Metamorphic cryptography considering concept of XOR and chaotic sequence: Using video as medium

Abstract

Society increasing dependency on modern digital world allows more creativity in today's world. Increasing connectivity motivates cyber criminals to discover new ways to gain access to sensitive information for which they are not authorized to do so. Several types of research have been done in past and are still going on. To protect the sensitive information during communication, many researchers favor either cryptography or steganography. A group of researcher nowadays also favors the concept of metamorphic cryptography. Several algorithms have been proposed in past to perform steganography and cryptography. But LSB approach is most frequent and popular technique followed by researchers because it simply inserts bits of the message into LSB of video frames. The presented paper contains the concept of an efficient algorithm using LSB approach but keeping in mind how to create less distortion and also creating a chaotic sequence for high randomness and encryption effect.
