可看見的浮水印可以作為智慧財產權的保護，而資料隱藏的技術可以做為認證的機制來判斷是否遭受竄改。在這篇論文裡，採用了調適性無失真可看見的浮水印的方法使得影像的品質能夠提升。方法中結合了PVMA與PPSA作為可看見浮水印的演算法。在資料隱藏的階段中，將函數選擇的紀錄與浮水印的樣式必須嵌入到影像中，這樣在還原階段接收端可以無失真的還原得到原始影像與浮水印。此方法的安全性也是一個討論的重點。

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.
