DEVICE AND METHOD FOR IDENTIFIER MANAGEMENT OF SOFTWARE DISTRIBUTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To monitor illegal copying by managing a distribution destination of distributed software with information including an identifier. SOLUTION: When a host computer 11 at a distribution center sells software through a network 12 at a request from a user terminal, each terminal is given a terminal identifier (MID) and a terminal password (MPSW) and the user is given a user identifier(UID) and a user password. The software is sold having a distribution identifier embedded. The host computer 11 relates those identifier to password and manages a history of sale. When the sold software is destroyed, restoration service is provided by referring the sale history. Each time the host computer 11 is accessed, the terminal password of the terminal is rewritten and it is checked whether or not the host computer is accessed by using the latest terminal password.
