Cryptography and Data Compression helps to combat hacking and theft. This subject ensures that students get proper training in data compression and coding that are broadly used in computers. All the fundamentals of data security lie in this course and training from a very basic level is crucial for the said purpose. The ground rules of compression are instructed for text compression, image compression, video compression and audio compression. The course content can be broken down to Shannon Fano coding, arithmetic coding, Huffman coding, family algorithms, dictionary techniques and entropy measures. Image compression has two dimensional versions, gray codes, JPEG, predictive techniques and loss less methods. MPEG is taught for industrial standard achievement in video compression. The topic of audio compression contains the elements of digital audio, frequency domain coding, M-law commands and ADPCM compression. Conventional encryption involves the use of topics like Steganography, encryption standards, S-box design, algorithm and international encryption.
