Abstract: Bills are fed from a customer serving section to a discriminator according to continuous feeding, and the discriminator reads identification information of the bills to store the identification information in an identification information storage. When the discriminator discriminates a bill, it determines whether or not the same identification information as the identification information of the bill is stored in the identification information storage. If the same identification information is stored, the customer serving section feeds the bills to the discriminator according to intermittent feeding. This prevents any bill from being undiscriminated.

Abstract: An image display system which improves the ease of use provided to an operator when an alteration is detected in image data that is to be displayed. An electronic watermark detecting section and forwarding request section are appended to a personal computer connected to a disk cache storing image data. The electronic watermark detecting section has a function of checking for alterations in the image data in the disk cache, and an interface to the forwarding request section is also appended thereto. A transmission section is appended to a personal computer connected to an optical disk device storing original image data. The forwarding request section has the function of sending a request from the electronic watermark detecting section to the transmission section, and the function of transferring the image data transmitted form the transmission section, to the electronic watermark detecting section.

Abstract: An unfair contents appropriation detection system capable of efficiently detecting the contents intentionally changed for the worse with ill will. If a contents browser terminal 130 obtains the contents appropriated by a contents appropriator terminal 120, an unfair contents appropriation detection program is incorporated into the above contents appropriated by the contents appropriator terminal. This program transmits alarm information AL to a watcher terminal 140 when a content browser terminal obtains the unfairly appropriated contents from the unfair contents appropriator terminal 120. Furthermore, in this unfairly appropriated contents, there is embedded a digital water mark for obtaining the changed area information of the contents. The watcher terminal obtains the contents from the contents appropriator terminal based on the alarm information AL and executes verification of the digital water mark with regard to the contents as obtained.

Abstract: There is provided an unfair contents appropriation detection system capable of efficiently detecting the contents intentionally changed for the worse with ill will.
