Digital watermarking on extracted key frames from uncompressed color video using 4-level DWT

Digital watermarks have been proposed as a way to handle the recent challenging issues like copyright protection and violation. The invisible watermark has many applications including video authentication, copy control, broadcast monitoring, fingerprinting, enhanced video coding etc. This paper propose a digital watermarking scheme on extracted key frames from uncompressed color video with another color watermark video using DWT. So, more information is embedded into original video while reducing the computation time and complexity compared to other schemes. This scheme is robust against attacks of frame dropping, frame averaging, noise addition and statistical analysis. Experimental results are shown to verify effectiveness and imperceptibility.
