Abstract
In this paper, an adaptive lossless visible watermarking scheme for watermarking according to image quality is proposed. The proposed adaptive algorithm combines Pixel Value Mapping Algorithm (PVMA) and Pixel Position Shift Algorithm (PPSA). While embedding, not only the function chosen record but watermarking pattern is embedded. When extracting, the receiver is able to recover the original image and obtain the watermark. The security of the propose scheme is also discussed.
