What are some challenges of incorporating visual elements in technical instructions or manuals? The biggest challenge is when you use visuals elements you have to choose the right ones that are related to the subject or the topic you are writing about. It’s very important to choose carefully when using visual elements in manuals because you have to use ones that are specific to explain your points of the topic. Why are visuals important? It’s important because it will show how much you understand the topic you are explaining to others, and it will make it easy for the reader to understand what the writer is trying to explain. For an example, I am looking at a baby crib, and I don’t understand one or few of the steps, if there are some pictures it would be easy for me to look at the pictures and I can apply it to the crib, but if there are no images than I will be lost and It would take me longer. We will write a custom essay sample on School or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Are there times when it would be inappropriate to include visuals? Explain your answers. I bought my three years old son a crib, they have two parts of a manual the first one is explaining how to put the crib together but it has no images, so I tried so hard I got some of the crib right.I was made because I did not see any images to show me how to put the crib up; I was going to return the bed just because they did not include any images on how to do it. I do better when I see a picture than read the explanation, and it took me about two hours to get it but no luck. I looked in the box for the last time and I found the paper I was looking for, the one that has images on how to fix the crib step by step. It got the crib done within an hour and my baby boy was sleeping in it. I believe having visual elements in manuals is very important.

The eNotes Blog No More Smokin in the Boys Room Tracking Chips On the Rise for Junior High and High SchoolStudents

No More Smokin in the Boys Room Tracking Chips On the Rise for Junior High and High SchoolStudents I have a child in junior high and a child in high school. Every day, both of them must wear their school-issued identification card on a lanyard around their necks at all times. The doors to their schools are locked at 8:30 a.m.   After being checked out on a video camera and buzzed in, parents and other visitors must present a drivers license upon entering the building, and then that visitor is issued a sticker with a scanned image of their license picture and their name in bold letters.   The sticker must be worn at all times while on school grounds. My children do not attend school in the Gaza Strip. They are in a small Texas suburb where, honestly, the biggest threat to their well-being are West Nile mosquitoes, all of which, sadly, are too tiny for State-issued sticky-IDs. Still, it is not enough. Now in addition to their dog-collarserr.. I mean IDs, soon, they, like thousands of other Texas kids, will be required to have their IDs chipped, as in microchipped with GPS tracking devices that will let administrators and, presumably, teachers, know where they are at all times. Not surprisingly, there has been backlash. One student, Andrea Hernandez of San Antonio, Texas, just won the right to refuse to wear the embedded identification.   While Hernandezs reasons for balking at the requirement may be unusual (she believes the tracking is Satanic), many parents and students also contend that the practice is invasive and in violation of their rights. It all feels a little too creepily Big Brother-ish to lots of  dissenters. For their part, schools are embracing the GPS IDs because increased attendance means increased funding. Additionally, they claim that students rights being violated is inapplicable since the students are under age. Moreover, there are voices on all sides, parents, teachers, administrators, and students, who argue that there should be nothing to worry about and no objectionsif your student (or you) are where they (or you) are supposed to be. What do you think? Yes to chips or no? And why?

Business Management & Decision Making Essay Example | Topics and Well Written Essays - 2000 words

Business Management & Decision Making - Essay Example Strategies can be complicated and the decision-making process has to consider many factors. Ryanair is one such low-cost carrier that entered the market as pioneers in the budget airline industry and adopted a classical airline business model focusing on customer service. Their strategies in different areas like market segmentation, e-relationship with customers, marketing communication, their distinction in offering or abstaining from on-board and ground services have reached them this position. Ryanair, the Dublin based carrier, started its operations in 1991 on the very successful, Southwest Airlines Low Cost Leadership Model. Like most European flights, this airline offers a point-to-point rather than hub service. It offers no frills like seat allocation, meals or frequent flyer programs (SD, 2006). It aims to turnaround flights in 25 minutes and they have the shortest routes. Ryanair’s CEO is an accountant by training but an entrepreneur by inclination and he has amply demonstrated this ability in the success of this airline (Box & Byus, 2007). He has gone against the trade unions, the government officials and the competitors but he has achieved dramatic growth and profitability in this industry. Ryanair flies only Boeing 737s and is currently facing challenges escalating fuel costs, intense competition and regulatory framework in the UK. Despite these challenges, Ryanair has been able to create its own market due to its strategic decision making process. Success in marketing can be achieved by matching the organizational capabilities with the requirements of the marketplace. This matching is based on market segmentation. Expectation based segmentation is a powerful marketing tool in the services sector because it provides knowledge for customer identification, which aids better customer service (Diaz-Martin, 2000). They can tailor their actions to suit the individual requirements. Ryanair followed the expectation based

Gluten free diet Essay Example | Topics and Well Written Essays - 500 words

Gluten free diet - Essay Example The gluten containing substances should be known for sure because common food items that we consume in our everyday life which include pizza, pasta, sauces, cakes, cookies, soups and candies might also contain gluten. Certain sauces as well as wafers and chips are also known to contain gluten. Hence it is essential that before these items are consumed it should be checked if they are gluten free or not. This care should also be taken in the case of certain medications because vitamin supplements and medicines are also known to contain this substance gluten. To assist people in finding the appropriate food items for themselves the American Dietetic Association provided the names of items which were free from gluten. These include rice, potatoes, corn and nuts. It is also known that fruits and green vegetables are free from gluten. To further assist in this process the Food Allergen Labeling and Consumer Protection Act (FALCPA) in the United States was created in the year 2006. This ac t required the food processing companies to clearly mention the name of allergens on the bottles so that the consumer might be sure about the presence of gluten. The disease states in which a strict gluten free diet is recommended are known as celiac disease and dermatitis herpetiformis. It is also known that for children who suffer from autism it is helpful to recommend a gluten free diet for them. Celiac disease results due to the disturbances that occur in the intestine when gluten comes in contact with the lining. It leads to the initiation of an inflammatory process which damages the lining of the intestine and hence results in poor absorption form the small intestine. The patient complains of symptoms related to the gastrointestinal tract which include pain in the abdomen, vomiting, constipation and weight loss. In long standing cases the patient develops anemia which results due to the deficiency of anemia. Dermatitis herpetiformis are skin lesions that occur with or

The Prophet Muhammad Essay Example | Topics and Well Written Essays - 1000 words

The Prophet Muhammad - Essay Example Muhammad’s Uncle took and grandfather took care of Muhammad. As a young child, Attwell insists that Muhammad usually suffered from seizure fits. During the fits, Muhammad mentioned receiving voices from heaven and heavenly visions (Attwell, 2007). Attwell prescribes some tribes described the young boy, Muhammad, as demon-possessed (2007). Growing up, Muhammad learned the teachings of the Jewish religion and the Christian Church. Consequently, some of the two religions’ teachings were incorporated in the Koran. The Koran teaches that Jesus Christ is a prophet, just like Moses. Growing up, Muhammad prayed to 350 various gods, including the Moon God, Al-lah. The author proposes that Muhammad’s knowledge of Jewish and Christian teachings of the Angel Gabriel visit (Attwell, 2007). Consequently, Prophet Muhammad espoused that Angel Gabriel visited him in Mount Hira, after marrying the 40 year old wealthy widow, Khadijah. Confused about receiving visions, Khadijah and his relatives convinced Muhammad that they were real visions. The author, insist that this situation casts doubts on authenticity as a prophet (Attwell, 2007). Gahl Eden Sasson insists Muhammad insists he quarreled with Angel Gabriel when he was instructed to recite and surrender to the will of God (2008). However, Angel Gabriel â€Å"the angel overwhelmed me in his embrace until he had reached the limits of my endurance. It took a bear hug and some wrestling moves o the part of the archangel to get the Aries (Muhammad) to submit to God’s will (Sasson, 2008 p.124).† Muhammad also mentions that he met Adam in the first heaven and Jesus and John the Baptist in the second heaven, when Angel Gabriel brought him to visit heaven (Spencer, 2007). In fact, Lionel Attwill’s biased resolution indicates Muhammad’s unstable and mentally disturbed condition, magnified by his continued fasting and meditation to receive visions is reminiscent of schizoid delusions (Attw ell, 2007). The author insists that the scripture depicts Angel Gabriel as reassuring Mirriyam, mother of Yahsua by telling her â€Å"Hail, O woman richly blessed The Yahweh is with you. Do not be afraid for you have found favor with Yahweh† (Attwell, 2007; p. 260). The author insists that Angel Gabriel never hugged or squeeze the lady until she thought she was going to die and leaving her cold and doubting her vision and eager to take her own life, because of the Angel Gabriel visit. Being an illiterate all his life, the author insists that Muhammad did not write the Koran (Attwell, 2007). After Muhammad’s death, his followers wrote the Koran from memory and hearsay. The author further states that the Koran verse stating Muhammad was â€Å"escorted to the seven heavens on a white horse to the temple mount in Jerusalem is a myth without any evidence (Attwell, 2007, p.261)†. Likewise, the author insists that Muhammad assimilated prayer to Allah, the pagan religio n’s moon god, into the Islam religion. The author further states that there is no record of Muhammad curing the sick, saving the sight of the blind people, casting out demons, or any other miracles, like the other prophets mentioned in Christian and Jewish scriptures, including Jesus and Moses. Further, Goldschmidt proposed Muhammad was a liar. Initially, he instructed all Muslims to avoid praying to idols or images. However, to gain the favor of the current Meccan leaders, Muhammad made a 180 degree religious policy shift. To espouse increasing the spread of the

Advantages And Disadvantages Of Encryption Security Types Computer Science Essay

Advantages And Disadvantages Of Encryption Security Types Computer Science Essay An Egyption scribe used non-standard hieroglyphs in an inscription about 1900 BC. Example of written cryptography is the first documented that lists by Kahn. A piece of flat stone carved into a collage of images and some writing to identify themselves in trading dealings in 1500 BC antique Assyrian merchants used in intaglio. The digital signature produced by this mechanism. This signature belongs to the trader, but they only have that intaglio to produce the signature. The reversed-alphabet simple replacement cipher known as ATBASH is used by Hebrew scribes writing down the book of Jeremiah in 500-600 BC. A small number of Hebrew ciphers of the time are only one that is ATBASH. Skytale a device used called by Greek which is a staff around that a long, thin strip of leather was wrapped and written on. The leather was taken off and worn as a belt. It would seem that a matching staff and the encrypting staff would be left home by the recipient. In the field of 100-44 BC in government communications used a simple substitution with the normal alphabet by Julius Caesar. This produce only in a little amount, but it is not stronger like ATBASH.When this read by few people it was good enough. Julius Caesar didnt trust the messengers but trusted his associates. Inspired the solution of a cryptogram in Greek for the Byzantine emperor by A.D Abu Abd al-Rahman al-Khalil ibn Ahmad ibn Amar ibn Tammam al Farahidi al-Zadi al Yahmadi wrote a book on cryptography in 725-790. Plaintext at the massages start was based on the result. It was a regular cryptanalytic technique and used still in WW-II in opposition to Enigma messages. Kahn has found the first model of the nomenclature. A grouping replacement alphabet and small code compiled by Clement VII at the appeal in 1379 Gabrieli di Lavinde. For the next 450 years this class of code was to stay in common use in the middle of diplomats and some civilians. There were stronger ciphers being imaginary in the interim in the face of the truth, probably because of its relative expediency. The manipulative a cipher disk to make things easier the process, its make-believe and available the first polyalphabetic cipher at 1466 Leon Battista Alberti. Until the 1800s, this type of cipher was actually not working. In addition his own creation, Alberti wrote expansively on the position the art in ciphers. He also used the disk for enciphered code. These systems were much stronger than the nomenclature. The first book wrote on cryptology at 1518 Johannes Trithemius. Each letter was represented as a word taken from a succession of columns that make-believe a steganographic cipher. The now-standard form of rectangular substitution tables is described as polyalphabetic ciphers. The notion of varying alphabets with each other introduced by Johannes Trithemius. The key for a repetitive polyalphabetic cipher is introduced at 1553 Giovan Batista Belaso the opinion of using a passphrase. Introducing the digraphic cipher wrote a text on ciphers at 1563 Giovanni Battista Porta. Transposition, substitution and symbol substitution are classified as ciphers. To confuse the cryptanalyst he uses the optional of synonyms and misspellings. The first authentic plaintext and cipher text auto key systems together with wrote a book on ciphers at 1585 Blaise de Vigenere. A biliteral cipher known today as 5-bit double encoding at 1623 Sir Francis Bacon described a cipher which now bears his name. Dr.Robert Patterson make-believe his wheel cipher perhaps aided at 1790 Thomas Jefferson. The father of US cryptanalysis was in a job as a civilian cryptanalyst at Riverbank Laboratories and performed cryptanalysis for the US Government is be honored at 1917 William Frederick Friedman. The Enigma machine was taken over and superior upon to become the cryptographic workhorse of Nazi Germany at 1933-1945. But the Enigma machine was not profitable success. U.S. Data Encryption Standard preferred with changes by the US NSA based on the Lucifer cipher a plan at 1976 by IBM. New Directions in Cryptography, introducing the suggestion of public key cryptography in print by Whitfield Diffie on 1976. The Diffie-Hellman was stimulated on 1977, paper and acting as complete novices in cryptography, Ronald L. Rivest, Adi Shamir and Leonard M. To make a useful public key system had been discussing by Adleman. The full scientific report to anyone submitting a self-addressed, stamped envelope offer was included in the Scientific American article. An application for a New Block Encryption Standard a planned International Data Encryption Algorithm (IDEA) was published on 1990 by Xuejia Lai and James Massey in Switzerland. The warning by the FBI to require access to the clear text of the interactions of citizens. PGP (Pretty Good Privacy) was the unrestricted first description on 1991 by Phil Zimmermann. The earlier RC2 and RC4 algorithms included in RSADSIs BSAFE cryptographic library the author was Professor Ron Rivest on 1994. The user can vary the block size, number of rounds and key length, if the algorithm uses data-dependent rotation as its non-linear operation and parameterized. Introduction to Encryption Systems Encryption is a process to encrypt the messages that can be readable by the person who knows how to decrypt the messages. This method has been used for over 2,000 years. The encryption is refers to the translation of a data into a secret code by using the algorithms. In the science of cryptography the process that involved is encryption. The messages must be securely sent. These messages could be numeric data, text or secret codes. For example, Missile Launch Codes. This encryption systems providing privacy for the authorized peoples communications. The receiver must have a key to decrypt the message to return to its original plain text form. The key that use to decrypt the message is trigger mechanism to the algorithm. Nowadays, encryption systems is the advent of the internet and public used it rarely. Moreover, these systems became largely military tool. There are used this systems in many field. Such as banking, online marketing, healthcare and other services. Even the average householder is aware of the encryption. When an address beginning with https that shows that web browsers is encrypt text automatically when connected to a secure server. When connected to a secure website, even the browsers automatically encrypt the information but many of them still choose the use of the encryption to do their email. The feature plug-ins or interfaces for the popular email clients will be easily accomplished with the help of encryption program. The most popular and longstanding is called PGP (Pretty Good Privacy), a name for very strong military-grade encryption program. It will be allowed to not only for the messages, but also may used for the personal files and folders as well. When the information tra vels between the computers, interception of the transmission that cannot be readable because it was in unreadable gibberish. Even there are many types of encryption but not all types of encryption are reliable. Other than that, there are same computer that yields strong encryption that can be used to break weak encryption schemes. Earlier years, they used 64-bit encryption and they taught that was quite strong but it was break by the 128-bit encryption. This is the standard encryption and this will not change in the future. It was undoubtful.The data makes private by the strong encryption. But, it is not compulsory will be secure. If the used data wants to be secure, the recipient must be positively identified as being the approved party. The digital signatures or certificates are usually accomplished online. Types of Encryption The encryption consists of 5 types of encryption systems. There are manual encryption, transparent encryption, symmetric encryption, asymmetric encryption and email encryption. Firstly, manual encryption. This type of encryption involves the use of the encryption software. This encryption encrypts the computer programs in various bits of information digitally. Users participation must completely involve in this encryption. If the wants to encrypt the file, the user have to choose the type of encryption from a list that provided by the security system. This may use in the personal computers. For the reason that is the user easy to encrypt the personal files in a way they like, and also it will be protecting the personal material on a computer. Secondly is the transparent encryption. This encryption can be downloaded onto a computer to encrypt everything automatically. This is the most protected type, since it doesnt leave out anything. The computer has an encrypt duplicate in every ex ecutable appliance and folder that formed endure authority surges and defends information in casing a computer is stolen. In addition symmetric encryption also defined as one of the type of encryption. By using this type of encryption can easily encrypt information by own self. For an example, a letter or number coincides with another letter or number in the encryption code. The code can make by ourselves. Such as a=1, b=2 and so on. Besides that, asymmetric encryption is a safe and easy way that can be used to encrypt data that will be receiving. This type will do by electronically. The public key can be seeing by whoever want or post somewhere. Others can encrypt the information and send it back. There is also another key even the public key decipher that is private key. This key has only one person have. This means the data will encrypt by public key but it can be read only by the whomever has the private key. Lastly the email encryption is typically same as asymmetrical encryption method. This method is the emails that in inbox cannot be read by others especially by the hackers. There are 2 types of email encryption. The result in who gets the private key to the email is the first an email supplier. The client of an email address is given by regularly. The second type is managed over who gets the key gives by the user. This way the encrypt emails can read by others who have the private key given. Types of Encryption Software There are two main encryption-software types: Disk-encryption software, which protects mutually programs and data Data-encryption software, which protects just data Disk Encryption Software This type of software also called as full-disk-encryption software that used to protects the complete hard drive. This including the operating system, all software programs and its folders and files except for the MBR (Master Boot Record). Disk encryption hardware will protect the whole hard drive as well as MBR. This software no needs to buy, it will be already contain in a new computer or upgrade to a new operating system. For instance, Microsoft Vista and Windows 7 Enterprise and Ultimate editions. This software will protect the computer when not using it only. The laptop must switch off when not using it. Data Encryption Software This type of software will protects the chosen folders and files in an implicit vault, volume Or safe. In the computer must be store all the sensitive data in a virtual vault. When the virtual vault is closed only the data encryption software will protects the data. Whereas not actually working on any data within it should always closed the virtual vault. Process of Encryption 1The Encryption Process Binary message is very simple process of encryption The binary message is simply xored with another binary sequence The second sequence must be random Example: Let the message be ECE 101 Using ASCII encoding, we get: 45x 43x 45x 20x 31x 30x 31x In binary form: 01000101 01000011 01000101 00100000 00110001 00110000 00110001 Now select a random sequence of equal length, example: 1010011 1000011 0101101 1101110 0110010 1010001 1101010 The encrypted message is then: E C E SPACE 1 0 1 45x 43x 45x 20x 31x 30x 31x 1000101 1000011 1000101 0100000 0110001 0110000 0110001 $oplus$ 1010011 1000011 0101101 1101110 0110010 1010001 1101010 = 0010110 0000000 1101000 1001110 0000011 1100001 1011011 16x 00x 68x 4Ex 03x 61x 5Bx SYN NULL h N ETX a [ 2The Decryption Process To decrypt the encrypted message it must be xored with the same random sequence that was used for encryption. SYN NULL h N ETX a [ 16x 00x 68x 4Ex 03x 61x 5Bx 0010110 0000000 1101000 1001110 0000011 1100001 1011011 $oplus$ 1010011 1000011 0101101 1101110 0110010 1010001 1101010 = 1000101 1000011 1000101 0100000 0110001 0110000 0110001 45x 43x 45x 20x 31x 30x 31x E C E SPACE 1 0 1 Fundamentally, this works because $0 oplus 0 = 0$and $1 oplus 1 = 0$ $x oplus 0 = x$, for x=0 or x=1. 3Comparison of secret key and public key cryptography Uses of Encryption There are five uses of encryption: Uses of encryption Details Confidentiality The person correspondent or the recipient can normally be implicit of encrypted data Error Detection The inside of the message have not unintentionally changed will be checking User Authentication The recipient that the correspondent is the real creator and not someone else by the verification Message Authentication The messages have not been lost or interfered with when do the verification Proof of Origin The message came from the declared correspondent is providing to the third party Types of Encryption Algorithms There are six types of encryption algorithms. They are RSA, DES/3DES, Blowfish, Idea, Seal and RC4. The key length is discerned by the strong encryption used the algorithms. RSA The idea of a public key system was proposed in 1977. After, this proposed the 3 mathematicians, Ron Rivest, Adi Shamir and Len Adleman give a concrete example of how the method can be implement. A private and public key was used by this system and this method refers to RSA Scheme. This system used the term n=p*q. DES/3DES U.S was developed and endorsed the Data encryption Standard (DES) in 1977 as official standard form. A block cipher with 64-bit block size that uses 56-bit keys by DES. Some of them not concern about the DES secure. The Triple-DES (3DES) has emerged with a strong method. With the help of DES/3DES giving it a cumulative key size of 112-168 bits. BLOWFISH This is like a symmetric block cipher same as DES or IDEA. The blowfish was created on 1993 by Bruce Schneier. Then it gets acceptances as a strong encryption. IDEA On early 1990s the International Data Encryption Algorithms (IDEA) by Dr.X.Lai and Prof.J.Massey in Switzerland replacing by the DES standard. This system uses encryption and decryption at 8 bytes in a time. SEAL In 1993 Software-optimized Encryption Algorithm (SEAL) was designed by Rogaway and Coppersmith. Block Ciphers is slower than Stream Ciphers. This SEAL is considered very safe because it has 160 bit key. RC4 Ron Rivest was invented RC4 cipher. Commercial systems like Lotus Notes and Netscape was used this cipher. This cipher used 2048 bits (256 bytes) key size. It relatively fast and strong ciphers. Advantages and Disadvantages Encryption is playing a most important role in day-to-day. Even it play role in important, there also have some negative points. Advantages Disadvantages The information that stored in the computer from not permitted access-even from people who not have access the computer system that can be defend An aggressor can cooperation the encryption series itself The transmission from one computer to another computer can protect the information An aggressor might find a earlier anonymous and comparatively simple way to translate messages encrypted with the algorithm that using The data can be used to deter and detect accidental or intentional alterations The deleting all the data cannot be prevent by attacker To know the author of the document can be verify Before it is encrypted or after it is decrypted could access the file by attacker Cryptography VS Encryption Cryptography Encryption The science and study of secret writing is defined as cryptography The desktop-computer insurgency has made it likely for cryptographic techniques to become widely used and accessible to no experts Cryptography is a part of the history, on the ancient years complex based codes and algorithms and machines was created By having some secure communications the Enigma machine was developed by Germans, throughout the World War I The secret Ultra project through World War II was Enigma codes that decrypted by the British Users suggestion is always encryption of the unbelievable on system, or the holder or the law of the enforcement This system changed a plaintext to the cipher text, which always has the look of casual The encrypted form called as cryptogram, the process of the encryption will be determined by the encryption algorithms The transformation will be truthfulness, genuineness and privacy provides by the encryption The information that send by the A is authentic and has not been tampered Algorithm Compression Loss Authenticity IEDS No No Yes SCAN Yes No No MIE No No No CIE No No No VQ Yes No No DRP No No No VC No Yes No 4Figure 2.1 Image Encryption Algorithm Property Comparison Table Importance of Encryption This is a very mysterious subject. The administration seems have no realistic application outer surface. The computer has distorted the age. In this world has do whole thing was recorded on computers that was connected to the Internet. There are many areas use encryption: The outsiders cannot snatch a copy of the transit that will assure by the encryption. The transit will be going between the commerce with many places of work locations needs to send computer data files among themselves. The encryption system allows them to hide the information among themselves when dissimilar people share the computer system. But nowadays almost they share similar in some form. The possible document only can read by the person who designed the encryption. Even others have the physical access to it. This issue modified encryption keys to the people. If everybody keeps their personal data in encryption form, this was worried by the law enforment authorities. Because of this, they tried a limit of using the strong encryption by the general public. The encryption software treats as military ammunition by the laws of the United States of America and it will be allowed export with case-by-case permission from the government. Examples of Encryption There are few examples of encryption. This example can easily break by the unauthorized people. By this examples, can understand more about the encryption. Reverser Decode EncodeThis type will be the reverse of whole message. If someone want to look the encrypted words, they can see the words by the backwards. Example: hello olleh hello Shifter Decode EncodeThe letters incremented by one so a becomes b, b becomes c and so on. The message will be more easier when incremented. By this type of encryption also others can see the letters. Example: hello ifmmp hello Flipper Decode EncodeThis is done by flipping every two characters. This is done by switched the 1st and 2nd letters, 3rd and 4th letters and so on. This also easy to encrypt the letters again. Example: hello ehllo hello Caesar Cipher Decode EncodeThis was made by Julius Caesar. This can be seen in the history. This also can be easily broken. The encrypted message is being used to replace the real message. Example: hello khoor hello Challenges and Technologies 5The encryption is very useful to the worldwide. Even it is useful, there are some challenges that faced by the encryption: GLBA compliance and emerging technologies by Paul Rohmeyer, Contributor The second decade of managing information risks under the regularly oversight of Section 501. RSA 2008: Financial industry security challenges The unique security challenges facing the financial industry its talks by the Executive Director Ed Zeitler. This can put strain on IT. Overcoming USA Patriot Act challenges This was contributors by Michael Rasmussen and Michael Landers. The authority to regulate various activities of financial institutions and they required them to maintain anti-money laundering programs. Regulatory and competitive forces The privacy laws are required to protect identity and personal financial information from unauthorized parties. Key management challenges and best practices This explains that to all procedures related to generation, exchange, storage, safeguarding, use and replacement of keys. BITS releases guide for implementing email authentication protocols 500s consumer-facing services brands adopted DKIM and Sender ID (SIDF), Microsofts version of SPF. The challenge is to locating all their sources of email. 6Other than that, there some technologies in the encryption. RSA encryption system was the top of the list, it developed by Ronald Rivest, Shamir, and Leonard Aldeman in the late of 1970 at the Massachusetts Institute of Technology. Security Sockets Layer (SSL) is a public-key encryption seems widely used in client-to-server applications. It was developed by Netscape and supported by Microsoft browsers. This SSL was suffered from its complex computation system, which prolongs the time it takes to perform the encryption and decryption processes. Besides that, Pretty Good Privacy (PGP), also a technology was developed by Phil Zimmermman. It was released on 1991. This was easy to use and strong encryption. After 1996, PGP was launched as commercialize the software. Then, Zimmerman man continued to develop more the PGP. There are some companies operating over a large network to protect the information on their hard drives, the program was Symantec Corps Norton Your Eyes Only. On 2000, Wi ndows 2000 was equipped with automatic encryption schemes. Alternatively, the programs could encrypt data onto a company server and allow with authorized access the files to decrypt them. 7Language that used to develop the encryption The application in programming language must be in order form to develop it. There are two popular and relevant high level programming languages that is Java and C#. The features in terms and portability were compares between Figueroa n.d. and Java and C#. By this comparison can be identify which has the better performance in processing images. The both languages are portable based on the study. The architectures and operating systems in different to run a program in flexibility is refers to portability. The term of the programming languages was only portable for C#. Java in the other hand is portable for in source code, hardware and OS. When manipulate the image is converted into matrix where elements of the matrix represent a pixel of the image. There are two types of size, they are vector size and matrix size. C# is faster when both sizes are greater than 4096. Java is faster when processing small sizes. 8Technique of encryption Younes Jantan, 2007 has proposed a simple and strong method for image security using a combination of blocks based image transformations and encryption techniques. The original message divided into blocks, which is rearranged into a transformed image using a transformation algorithms and then transformed image is encrypted using the Blowfish algorithm. Without the key, encryption and decryption process cannot take place. The following figure shows the model of the proposed technique: Original Image Key Transformation process Encryption process Ciphered Image   Figure 2.2 An Overview Diagram of the Proposed Technique Depending on the key supplied by the different cipher codes have the similar image. The confidentiality and security will provide when the image based data transferred with the help of suitable user-defined key. The resulting image will not be generated because of the result of hash embedded inside the image file. The below figure shows the architecture proposed: Image Encryption Model Image Cipher Code (An encrypted image) User Defined Key Decrypted (Original) Image Image Decryption Model User Defined Key Figure 2.3 The Architecture of the Image Encryption and Decryption Model Future Improvements The future of encryption is brighter than ever before. The protection of corporation information assets and third-party information is increasing spectacularly and it is demand for more control. Even five years ago, the amount of information being communicated and stored by electronic means is hugely great. The information security products are growing at a higher rate than any other aspect of IT technology must be more effective within the enterprise today. From the perimeters of communication, the Internet and the mobility of its users have removed it. For the modern day enterprise the last line of the defense is encryption. In future, the encryption systems will be more useful to the users. Moreover, this encryption is tough, complicated, jargon and it is not user friendly. Even, by the IT people also cannot know what is actually encryption. How about the the common people. Many of them said that encryption is so great, why Microsoft did not use this. Because it is very expansive, too advance for the unknowledgeable persons and is not simple to use it. In future, the encryption will improve the PIN security. The unique encryption key can be used only by the EFT networks members only. But this costs high implementations, since some of the ATM owners ignored it. The remote key distribution may improve the compliance rates. There are 6 critical market drivers that will be the shape the future encryption  [9]  : Email privacy and regulatory requirements The global enterprises provided easy way exchange information can conduct the business electronically by the Internet and adoption of Internet protocols. Increasing compromises and unauthorized access to critical business information To improve the quality and level of protection enterprise employ to guard their information assets and the assets of their customers and business partners. The expanding enterprise The increasing number of regulations are aimed in a part at ensuring enterprises maintain and fulfill their fiduciary responsibilities. User mobility Ensure that the information during travel safe and the electronic communication also remain safe as it is transmitted across the Internet. Communications appliances Credit card may need protected for much longer periods of time. The Art of Storing and Retrieving Corporate Information Assets There are emerging the solutions for how to communicate among the various enterprise members in a secure manner. Conclusions The future of the encryption will be using by electronically for the purpose of enterprise conduct business. In future the encryption and the innovation of the applications providers. At Backblaze is protecting the privacy of the users data is a top priority that means encryption system. This is easy to use as a key part of the vision and makes the product hard to use for the encryption. For the military grade encryption made easy by mix of the public/private and symmetric key algorithms. The encryption is refers to the translation of a data into a secret code by using the algorithms. In the science of cryptography the process that involved is encryption. The messages must be securely sent. These messages could be numeric data, text or secret codes. For example, Missile Launch Codes. This encryption systems providing privacy for the authorized peoples communications.

Holocaust Survivors Essay -- Essays Papers

Holocaust Survivors Who survived the holocaust? What are their lives like today? What has been the government's response towards those who survived after World War II? Have the survivors kept their faith? How has the survivors next generation been affected? The survivors of the holocaust were deeply effected by the trauma they encountered.
