A Video Multiple blind Watermark Scheme Based on Discrete Cosine Transform
This paper presents a new type of video multiple blind watermarking scheme based on discrete cosine transform (DCT), which aims at the demand of multiuser copyright sharing protection. The scheme which combined the scrambling technology and human visual system achieves the multiple watermarks embedded in different frequency components by adjusting the DCT coefficients of the video frames green component. According to the video content, the scheme can selectively chooses the embed-depth, and then by embedding the binary image watermark into the DCT middle and low frequency coefficients of the video frames green component, the scheme can obtain the superior performance on the multiple watermark embedded in the video carrier and the blind extraction. The experimental results show that the scheme possesses the strong robustness on traditional signal processing attacks such as the Gaussian, frame shear, salt, etc. Furthermore, the scheme has low complexity and the strong usability.
