Insurance system

摘要

An insurance system that guarantees re-distribution of electronically distributed authorized data. The insurance system 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 electronically distributed through a network. Furthermore, the insurance system is constructed in such a way as to receive re-distribution through the insurance service server, which allows the insurance service server to control re-distribution independently and prevents illegal re-distributions as a consequence.
