Abstract :

The role of color image is very important today. The development of network and multimedia technologies, copyright protection and content authentication has become a serious problem today that need to be solved urgently. Digital video watermarking technology provides a strong solution for it.The DWT and DCT are two most popular transforms used in watermarking algorithm. The wavelet transform plays a vital role in the image and video digital watermarking, and watermarking algorithm based on Discrete Wavelet Transform (DWT) causes more concern. This paper presents a dual purpose digital video watermarking algorithm based on DWT of color images. In this paper, we choose a suitable algorithm to embed watermarking and used a Arnold transform and chaotic encryption to provide a security. Due to this the system can protect the copyright of digital products and the authentication of certificates. The original video will be converted into number of frames and then the frames are converted from the RGB color space to the YCbCr components. The robust and fragile watermarking encrypted is embedded in the frames. The DWT is applied to Y, Cb, and Cr component separately. The chaotic encryption is applied after robust watermarking and the Arnold transform with the chaotic to the fragile watermarking and then the watermark is added to every channel separately so that the sensitivity and robustness will be increased.
