Identification and verification of a video clip via its hash find application in broadcast monitoring. For broadcast monitoring, a novel method for computing a robust hash from video clips, being secret key based, is proposed based on the 3-D Discrete Wavelet Transform (3D-DWT) and median quantization. The proposed hash function is shown to be remarkably robust against video modifications and lossy compression. On the basis of the video hashing, a security video watermarking scheme for broadcast monitoring is put forward based on the communication diversity technique. Some analyses and experimental results show that the proposed scheme has good security and robustness.
