Data Security Using Cryptography and Steganography Techniques
Although cryptography and steganography could be used to provide data security, each of them has a problem. Cryptography problem is that, the cipher text looks meaningless, so the attacker will interrupt the transmission or make more careful checks on the data from the sender to the receiver. Steganography problem is that once the presence of hidden information is revealed or even suspected, th...
متن کاملCryptography in Data Compression
This paper describes cryptographic methods for concealing information during data compression processes. These include novel approaches of adding pseudo random shuffles into the processes of dictionary coding (Lampel-Ziv compression), arithmetic coding, and Huffman coding. An immediate application of using these methods to provide multimedia security is proposed.
متن کاملEnhancement of Network Security Techniques using Quantum Cryptography
Quantum cryptography uses the law of quantum physics for unconditionally secure data communications. This is a main achievement because the cryptography currently in use, known as conventional cryptography, relies completely on the hardness of a mathematical equation. The advances in quantum computing has threatened the computational security of classical cryptography, which in theory can effic...

متن کاملImage Classification Using Data Compression Based Techniques
Earth Observation applications are seldom usable on different kinds of data types, being strongly dependant on the characteristics of the sensor used (i.e. spatial, spectral and radiometric resolutions of the data), models adopted and a priori assumptions. We propose a parameter-free, model independent methodology based on data compression to perform image classification and indexing: data comp...
