A Security Video Watermarking Scheme for Broadcast Monitoring

Identification and verification of a video clip via its fingerprint find applications in broadcast monitoring, database search and transaction tracking. For broadcast monitoring, we propose a novel robust hashing algorithm for video based on the 3-D wavelet transform (3D-DWT). Then the watermark information and the short fingerprint using the proposed hash algorithm are combined to create the embedding information. On the base of the video hashing, a security video watermarking scheme is proposed for broadcast monitoring. Finally, the security of proposed algorithm is analyzed. Some experimental results, which prove the effectiveness of the algorithms, are presented.
