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 terminal130obtains the contents appropriated by a contents appropriator terminal120, 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 terminal140when a content browser terminal obtains the unfairly appropriated contents from the unfair contents appropriator terminal120. 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. The changed area of the contents can be automatically detected, thus the efficiency of watching the contents appropriation by the watcher terminal is enhanced.
