Abstract :
In this paper, a simple and robust watermarking scheme is presented by using random mapping function. The idea of the proposed algorithm is watermark embedding which can be more robust than the traditional LSB technique. Using the proposed algorithm, it makes the secure random coordinate of cover image to increase the robustness of the watermarked image. Experimental results show that the quality of the watermarked image higher in the case of the proposed scheme than using the LSB technique.
