About Our Project

With the enormous growth of Internet and advent of media communication technologies, scalable media (image, video etc.) coding is considered to be integral texture of video representation and transmission. In this coding approach adaptation is done in the media content to fulfill the varying transmission and presentation demands of the consumers.

Assuring protection such as ownership as well as video content authentication becomes an important part of efficient and secure multimedia communication. This poses challenging research problems especially in their scalable representation. Encryption and cryptographic hashes are proposed for this purpose. But it is observed that the scalability property of the bit stream is lost if the video bit stream is encrypted with conventional cryptographic ciphers.
