Watermarking is a potential method for copyright protection and multimedia data authentication in the Internet. The watermarking process can be considered as a communication task, where the watermarking acting like information embedded into a host image, which acts like noise in a communication channel susceptible to all kinds of attacks acting like as jamming. In this paper, a novel watermarking scheme using code division multiple access (CDMA) modulation is proposed to achieve a superior performance in terms of robustness and imperceptibility. In the proposed scheme, three watermark bits are modulated to five bits CDMA code. Then the CDMA code is embedded in the coefficients of a DWT domain. To explore the utility and demonstrate the efficiency of the proposed scheme, simulations under various conditions are conducted. The empirical results show that our proposed scheme can stand up against most common attacks.
