A Novel Algorithmic Approach for Information Hiding In a Video with Low Video Distortion

Data hiding in compressed video is the recent way of providing security. The main objective of data hiding in video is to transmit the message with security (by encryption) in streaming video. This paper presents a technique to hide secret data in the motion vectors of a compressed video which is not vulnerable to Stag analysis and also to maintain the quality and size of the reconstructed video. In this technique the secret message bit stream is embedded in the least significant bit of both components of the candidate motion vector. Also this paper uses a standard encryption mechanism (AES) in order to improve more security for the message. The proposed technique is found to have lower distortion to the quality of the video. “
