For the Triple Play Video Audit and Distribution Trust Mechanism

Abstract

For the new state of the triple play, video faces security problems and distrust problems between the subjects in the process of audit and distribution, and then we propose a new trust mechanism. The mechanism considering the video encoding, tampering and the human visual system (HVS), designs a method of video key information sampling, constructs a bit commitment (BC) protocol of sampling information group, and uses public key encryption for secure transmission by generating secret communication mark. The recipient verifies the communication mark and BC value to determine whether the video is tampered and locate the tampered area. The experimental results show that the mechanism has high security and credibility, effectively achieving the mutual trust between the subjects in the triple play.
