A copyright management system for online trade of digital images is proposed in which low-resolution images with a visible mark are freely downloadable. An authorized user receives a package containing the details of the image he/she buys together with a key for mark removing. Using a downloaded client-end routine, the user removes the mark, reconstructs the high-quality image and embeds a robust fingerprint in the image simultaneously
