Improved Mixed Video Watermarking Scheme
摘要
Abstract
Proposed an improve mixed video watermarking scheme. By embedding the robust and fragile watermarkings into AC coefficients of the middle frequency in the EXIT macroblock and the horizontal component of motion vector to a-chieve the gold of hiding the secret and verifying information in the video, we can protect the video copyright with the a-bility of the integrity certification. The results show that:compared to the mixed video watermarking scheme proposed by G. Qiu et al,when embedding the robust watermark, the code rate decreases by 6% on average and it owns a better resistance to attacks \ the fragile watermark is more sensitive to attacks.关键词
