Data Hiding in Video Streaming by Code Word Substitution

Abstract

Data hiding techniques can be used to embed a secret message and secret image into a video bit stream for copyright protection, access control and transaction tracking. They are some data hiding techniques to assess the quality of video in the absence of the original reference. To avoid the drawback of existing system such as lossless compression, gray scale mapping and noisy images forces higher bit plane when distortion are easily visible.Data hiding is also used for concealment in applications of video transmission, gray scale mapping and noisy image. Edge quality information and number of bits of a block are hidden in the bit streams processed in an encrypted format to maintain security and privacy.
