Block-Based Lossless Data Hiding in Delta Domain
Digital watermarking is one of the ways to prove the ownership and the authenticity of the media. However, some applications, such as medical and military, are sensitive to distortion, this highlights the needs of lossless watermarking. In this paper, we propose a new lossless data hiding algorithm in delta domain. A MSE discount is obtained by using checkerboard-pattern watermark sequences. The PSNR between the watermarked image and the original image is high and there is no “salt-and-peppers” artifact. The proposed algorithm can be extended to withstand the JPEG attack.
