Disclosure route browsing system and its disclosure route verification of personal information

摘要

PPROBLEM TO BE SOLVED: To provide a personal information disclosure route browsing system which can verify a disclosure route of personal information and the contents of the disclosure when the personal information is leaked or there is a possibility of a fraudulent distribution of the personal information. PSOLUTION: In the personal information disclosure route browsing system, when business firm side devices 105-107 disclose collected personal information to other business firms, the devices make disclosure permission requests to a disclosure route management server 101. The disclosure route management server 101 determines a distribution route and disclosure range of the personal information, to which the disclosure request is made, and then transmits disclosure-permission data, which include a permission ID, information on a disclosure-origin firm side device, information on a disclosure-destination firm side device and its own electronic signature, to a disclosure permission-requesting firm side device. The requesting firm side device prepares a disclosure route record comprising the disclosure permission data and its own electronic signature, adds the record to the disclosure route data which the personal information has and attaches the disclosure route data to the personal information to be disclosed and displays it.
