Digital watermarking provide an effective way for overcoming serious problems of digital images on the Internet,including copyright violation,illegal copying and genuine identification,etc.The authors develop a bi-image watermarking method.This paper introduces the commonly used Matlab function in the digital watermarking algorithm and accomplished a new kind of watermark-embedding and detecting algorithm based on the DCT.It has good robustness with the experimental results given that the image embedded watermark after the attack can be extracted successfully.
