Abstract: A processing device has a personal authentication information receiving unit for receiving personal authentication information, a security information DB, and a processing information managing unit. The processing information managing unit converts the personal authentication information received by the personal authentication receiving unit to a user ID, detects an event concerning a processing operation, and associates the event with the user ID, thereby creating or updating an access management table for processing performance information, for storage in the security information DB. The processing information management unit then controls access to the processing performance information based on the access management table and the user ID obtained by conversion of the personal authentication information received by the personal authentication information receiving unit.
