Abstract
This study introduces a technology utilizing digital images as electronic money by inserting watermark into the images. Watermarking technology assign contents ID to images and inserts the contents ID into the images in an unnoticeable way. The server that manages the issue and the usage of mage electronic money (called ‘WaterCash’ hereafter) stores issued contents ID to database and manage them as electronic money. WaterCash guarantees anonymity and prevents the forgery and modification of WaterCash based on semi-fragile watermarking technique. In addition, WaterCash is transferable and the illegal use of WaterCash can be prevented based on the watermarking technology. The watermarking .technology used in this paper was designed to be robust to image compression but vulnerable to intentional or non-intentional Image processing.
