PROBLEM TO BE SOLVED: To provide an information processor which permits the reference to the user data pertaining to another system under the proper protection of secrecy and also permits the reference to the user data according to the security ranks of a referred user and a referring user. SOLUTION: When a personal computer 2-1 issues a reference request to the data on a user pertaining to another system, this request is sent to an ID conversion part 6-1 via a user ID management part 3-1. The part 6-1 converts the user ID into a guest ID by referring to an ID conversion table 14-1 and sends the reference request to a user ID management part 3-2. The part 3-2 refers to a user ID table 11-2 to confirm registration of the guest ID. Thus, the reference request is sent to a user data management part 5-2 via a security check part 4-2 and the whole or an open part of the designated one of user data 13-2 can be referred to. |
