Abstract
A blind digital image watermarking algorithm based on DCT is put forward in this paper. The watermark is embedded in the host image through adjusting the magnitude relationship of the chosen medium frequency coefficient, which is easy to be implemented. The experiments have proved that the proposed algorithm is with strong ability in resisting shear attracts, noise attracts, compression attracts, and other common attracts, and reaches to both of the good robustness and the good invisibility.
