  • 摘要:The integrity video watermarking authentication algorithm is proposed based on DCT coefficients. Because of the characteristic of vulnerable to interference for high-frequency DCT coefficients, we use the relationship between the average energy of the high frequency coefficients and the energy of every the high frequency coefficients and Substitution cipher to beneficiate the Image Watermarking. The result is embedded in the intermediate frequency coefficients. Experimental results show that image of minor attacks will cause severe deformation so that it is difficult to extract the identifiable watermark. It can achieve the integrity authentication purposes.
