摘要:In this paper, a new method for digital image watermarking is proposed. The proposed method divides the pixel into two parts: semi-pixel 1 and semi-pixel 2. The watermark information bit is inserted at a pixel location according to the difference of two semi –pixels. The pixel for insertion of watermark is selected by using pseudo random number generator that is seeded with a secret key. Experimental results showed that the proposed method has given a good quality watermarked image
