Description

Digital contents can be copied without any loss of data, so the marketing system of them should have a mechanism to prevent illegal copies. However, the system should not decrease convenience of legal buyers. In this paper, the information marketing system with illegal copy protection is proposed; it only allows copies for private use, while keeping convenience of legal purchaser. The system prevents illegal copy, by encrypting rights for use with two informations and decrypting with either one when the contents will be used. The system has been appied to a PDF marketing system of the "Infoket". We have evaluated and improved the system to adapt to the actual services.
