A Video Watermark Method Based on Chaotic Encryption

Abstract:

An effective and integrated video watermark scheme mainly includes watermark generation, watermark embedding, watermark detecting, and watermark attack. The watermark data come from a meaningful binary image encrypted by two-dimensional chaotic stream encryption to improve watermark security. In the procedure of watermark embedding, watermarks are embedded into the random selected video frames through modifying the DCT coefficients. After robust and frame processes, watermarks can be mainly extracted and identified through watermark extracting algorithm. The experimental results show that the proposed video watermark method has some performances of security, imperceptibility and robustness.
