Abstract

This paper presents a new fast video watermarking scheme in spatial domain for embedded device identity verification. A binary watermark signal, which is produced by the identity of the embedded device such as the disc video player, is permutated using sequence numbers generated by a secret key. And then it is encoded by Gray code. Each bit of the binary encoded watermark is embedded four times in different positions, by modifying the intensities of a nonoverlapping block of 8*8 of the blue component of the frames in host video. In watermarking extract scheme, the frame of the watermarked video and the original video are decoded to images. And the intensities of a block of 8*8 of all components of the frame images in the watermarked and the original video are compared to calculate the probability of detecting '0' or '1' for extracting binary watermark. Both the embedding and the extraction of watermarks are done in the spatial domain, so the computational cost is low. Then the digital watermark with the identity information is embedded in real time to the video image when the embedded devices play their videos. Experimental results show that the algorithm has obvious low complexity, and the strong robustness against distortion, deleting, and cropping operations.
