Inventor: OHARA TAKAO
IPC: G06F21/33
Filed: 2001-01-26
Abstract: PROBLEM TO BE SOLVED: To conduct a user authentication with high reliability even for an Internet terminal of low level specification. SOLUTION: An authentication server 10 stores a table wherein the first identification information is made preliminarily to correspond to the second identification information. A key prepared optionally by the server 10 is received in a hand-held terminal 100. Irreversible change information of information including the key and the second identification information is computed thereafter to transmit information added to the irreversible change information with the key and the first identification information, as an authentication code. The second identification information is aquired in an authentication server 10 side based on the first identification information in the received authentication code, referring to the table. Then, irreversible change information of information including the second identification information and the key in the received authentication code is computed.  The user is authenticated when the resulting irreversible change information is consistent with the irreversible change information in the received authentication code.
