This paper addresses the problem of ensuring the integrity and the authenticity of H.264/AVC video. It is achieved by authenticating each Group Of pictures (GOP) within the video separately. The proposed technique uses content based digital signature generated from robust features extracted from transform domain as fragile watermark and then embeds it in motion vectors belonging to the GOPs with the best partition mode in tree-structured motion compensation. Experimental results show that the proposed detects spatial cropping and temporal in a video.
