| Summary: | In this paper, a frame-by-frame blind video watermarking technique, which is resistant against collusion attack, is proposed. Collusion attack is the main problem in video watermarking for copyright protection. Whereby in this attack, colluders try to estimate and remove the watermark by comparing with as many as watermarked materials. To address the collusion attack in this work, each frame is assigned a different watermark. Since each frame has a unique watermark, it is impossible for the attack to estimate it. To achieve the required robustness as well as maintaining the quality, a combination of Block Truncation Coding (BTC), Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) techniques is used. The results show that the proposed method is robust against all types of collusion attack, and at the same time, the quality of the video is maintained at a satisfactory level. |
