<P>PROBLEM TO BE SOLVED: To provide an insurance system that smoothly performs re-distribution of electronically distributed contents etc. <P>SOLUTION: The insurance system that guarantees re-distribution of electronically distributed authorized data is constructed in such a way that a right to receive re-distribution is generated contingent upon taking out an insurance policy, and can thereby implement an insurance system capable of smoothly carrying out re-distribution of contents etc. electronically distributed through a network. Furthermore, the insurance system is constructed in such a way as to receive re-distribution through an insurance service server, which allows the insurance service server to control re-distribution independently by the insurance server, and as the result, illegal re-distribution can be prevented. <P>COPYRIGHT: (C)2008,JPO&INPIT |
