Transform Domain Video Steganography Using RSA, Random DNA Encryption and Huffman Encoding

Now a days digital communication is a large pool of information and so its security and privacy are very sensitive and vital characteristics of the system. As far as success of any event is concerned, the keystone is effective and safe communication. We are presenting here a novel approach wherein RSA, random DNA encryption, Huffman encoding and 2D DCT steganography melds to give a system with guaranteed three levels of security. As compared to existing methods, the new approach is found to improve the quality of steganographic system and deciphering the codes will be much more cumbersome.
