Considered the authentication of video clips applied in broadcast monitoring

a new robust hashing algorithm for video was proposed based on the 3D wavelet transform （3D DWT）. The new proposed algorithm could realize the authentication of video clips by using the embedded watermark information created by the hash value and the watermark identifier. This new robust video watermark algorithm could also be applied in the security of broadcast monitoring. Based on the academic analysis and experimental results

the new proposed algorithm has good security and robust performance.
