| Abstract | In this paper ,We introduced a novel method DS-CDMA based watermarking scheme on the basis of orthogonal pseudorandom sequence subspace projection, In this paper a new idea to eliminate the correlation between the code sequences and the host images in the watermark extraction phase, and in watermarking scheme improve the hiding capacity of message sequence. In our proposed scheme implements the steps and performance checking under different attacks by a series of experiments. The results observe the Host image under different attacks and show the higher robustness and achieve the high capacity to hide the data. In our proposed scheme implements the steps and performance testing under different attack conditions by a series of experiments. The experimental results observe the Host image under different attacks and show the higher robustness and increase the message capacity and achieve the high capacity to hide the data. |
