| Abstract | ||
| In this paper a new digital video watermarking scheme based on detection of video key-frames using histogram color techniques. The watermark is embedded in the DWT of the blue band of all key-frames using LSB algorithm, (as blue color is less sensitive to human visual). Stream cipher is included in the proposed scheme for encryption of the watermark for better security. The watermark is recovered by averaging the watermark from all the key-frames. Results show that the proposed method is robust against different type of attacks like lossy compression, frames dropping, frames swapping, sharpening, lightening, darken, noising, and distortion. | ||
