Title: Authentication and management device
Inventor: SUGIYAMA AKIRA
IPC: G06F21/44
Filed: 2000-03-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce the responsibility and duty of a user of an application and data, and in addition, those of a manager, by letting a computer determinately perform registration and management of an ID, and setting and management of a password. SOLUTION: In communication between two parties' computers in time and space (an eigen-time system) from a start date and time QB0 up to an end data and time QE0, transmission timing of an accessing side exists surely earlier than that of an accessed side in the eigen-time system. A receipt time of specific communication data from the other party, a transmitted time of the specific communication data to the other party or the like in the eight-time system can be used by each other as inherent authentication data of the partner so that specific communication partners can be determined more surely with high accuracy. Namely, by repeating transmission and reception of the communication data between the specific communication partners, it is possible to determine the positions of the partner's computer like UP1, UP2, and UPn in the eigen- time and perform exact authentication.
