Adaptive Video Watermarking Scheme for Effective Resistance to Linear Collusion in Spatial Domain

  • A mathematical model was established to solve the problem of linear collusion attacks in video watermarking.From this model,the design rules of video watermarking for resistance to linear collusion were put forward.In addition,an adaptive video watermarking algorithm for effective resistance to linear collusion was proposed.Furthermore,some nonoverlapping blocks(subframes) 8 by 8 were adaptively selected as embedding regions,and watermark strength was adapted proportionally to the variances of the subframes.The experimental results show that with the proposed algorithm,the correct rate to extract watermark can reach 100% after linear collusion,frame removal,frame insertion,frame reorganization and MPEG(moving picture experts group)-2 compression.
