Cryptography Vs Steganography

Datatype Description smallint 1 byte is the minimum storage needed int Uses only the bytes that are needed. For example, if a value can be stored in 1 byte, storage will take only 1 byte bigint Uses only the bytes that are needed. For example, if a value can be stored in 1 byte, storage will take only 1 byte decimal This storage is exactly same as the vardecimal storage format datetime Uses the integer data representation by using two 4-byte integers. The integer value represents the number of days with base date of 1/1/1900. The first 2 bytes can represent up to the year 2079.

31. Which level of RAID refers to disk mirroring with block striping? a) RAID level 1 b) RAID level 2 c) RAID level 0 d) RAID level 3 Answer: a 32. A unit of storage that can store one or more records in a hash file organization is denoted as a)

Ever since data is in encrypted format, its probably difficult for attacker to decode it ; but this will ultimately lead to data owner to suffer in one or the other way. 6. In order to solve this problem metadata is stored for each server content into proxy server. 7. Suppose size of data stored in server 1 is 2GB and similarly size of data stored in server2 is 2 GB.

• ICMP; is one of the main rules of the internet protocol suite. It is used by system devices, like router, to send error messages showing, for example, that a demanded service is not offered or that a crowd or router could not be touched. • DHCP; Dynamic host configuration protocol is a customer server rules that repeatedly delivers an internet rules (IP) address and other linked arrangement information such as the subnet mask and avoidance entry. • Bluetooth; Bluetooth is a wireless communication technology that lets people to usefully connect their plans with other policies “and “the character of the technology is developing to not only allow devices to talk with one another, but actually allow the all-in-one communication between devices, native requests and the cloud.” •

Invisible ink is a liquid that is used to send messages that can only be seen when affected with chemicals (dictionary.reference.com). The ink was used to send special messages to others so prying eyes can not see the message. This type of ink has been used for hundreds of years to communicate. Invisible ink was used by Germans during the first World War to communicate with each other to pass on information about England (scientificamerican.com). Invisible ink was also used during the Revolutionary war by both the Brits and Americans (clements.umich.edu).

According to the article “Spy Letters of the American Revolution” and “Spy Techniques of the Revolutionary War” invisible ink contained ferrous sulfate and water. The code would be in the lines of a normal letter and the code was revealed by adding heat to the paper. Ciphers are another way of communicating in the spy world, both the British and Americans used these techniques. Ciphers were coded letters that

I assumed that the word meant being quiet and secretive, because it was information that was best if kept hidden. The Merriam Webster dictionary defines the word “discreet” as “not likely to be seen or noticed by many people”. I think the author

Source music as an element is the music whose genre is called dogme 95. There formally form a source in a film which could be a television set or a radio. They are called source music because they come from a screen source that can be inferred. Structure as an element of film score refers to the way the score was composed to fit a particular that the director was displaying. Music might be played incidental depending in the variation the film is played.

At the end of our presentation we clarified that many music companies breach these laws, however they receive no penalties for doing so (evidence can be found in our script). We presented to a class of year twelves but hope to later present to a mature group of year eleven

For example, your entire class fails a test and your teacher lets you retake it. Since you already know you did badly on the test, you do not want to fail it again. So you cheat your way out of it. You all finish the test without getting caught. Eventually your teacher will find out you cheated.

I. INTRODUCTION Optical camouflage is a active camouflage. The concept is simple. If the background image is projected on the object painted with retro reflective material, it creates invisibility. Digital Video camera, computer,

This would embed the message into a metal cylinder with tin foil wrapped around it. Which could be played back multiple times before causing damage to the tin foil and losing the recorded

These codes can be shown as symbolic, written, audio and technical. Each one of these elements helps to categorised and helps to determine the genre. Conventions are what an audience typically expects from the genre. The producers and directors then in turn use what the audience expect in order to make the genre desired. Narrative conventions are the expected characters, settings, storylines and themes of a particular type of genre.

The word steganography is of Greek origin and means "covered writing" or "concealed writing”, Cryptography and Steganography are ways of secure data transfer over the Internet. Cryptography scrambles a message to conceal its contents; steganography conceals the existence of a message. It is not enough to simply encipher the traffic, as criminals detect, and react to, the presence of encrypted communications. But when information hiding is used, even if an eavesdropper snoops the transmitted object, he cannot
