More Information
Summary:Several techniques have been developed for the security of the secret data or information such as steganography, cryptography but among these the digital watermarking technique is the highly securable and imperceptible technique. In this technique, a piece of information known as watermark is hidden in the cover/host image, audio or video for the security purpose. Most of the techniques are generally applied over the RGB color space. But this research paper laid stress on the YCbCr and CIELab color spaces to determine the effective or efficient color space for the embedding and extraction of the watermark with more security with minimum BER. The proposed algorithm for these two color spaces is simple, secure and robust against different attacks.
