Enhanced Color Image Method for Watermarking in RGB Space Using LSB Substitution

Nowadays, with the rapid advancement of internet and the development of digital contents the enormous use of digital data such as multimedia services on the web become a fact. As still images, videos and other works are available in digital form, the ease with each perfect copy can be made may lead large scale unauthorized copying. In this paper a new approach for still image watermarking using least significant bits LSB technique is presented. The proposed algorithm satisfies the invisibility of the embedded colored JPEG image into the cover data under normal viewing conditions. The experimental results based on Matlab simulation by testing Mean square error (MSE), Peak signal to noise Ratio (PSNR) and Normalized Correlation (NC) show that the quality of the watermarked image of our system is higher.
