Digital image watermarking is the technology used to protect copy right information of multimedia objects. This paper presents a more secure method for copyright protection. In this scheme color image is decomposed into R, G, B channels and then DWT and DCT transformations are applied on these channels separately. The bits of watermark image are embedded into middle frequency coefficients of transformed R, G, B channels. Results reveal the performance of proposed algorithm using the metrics Peak Signal to Noise Ratio and Normalized Correlation and comparison of proposed scheme with the existing methods which used DWT-DCT transformations.
