CALL BACK REMOTE ACCESS METHOD AND DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a call back remote access device which prevents the grant to a potential wrong access when a remote access is executed by means of the call back authentication and ensures high security. SOLUTION: A call back request accepting circuit 111 is prepared independently of a dial back circuit 112. A user gives a request to a call back request processing part 101 of a remote access device (server) 100 via the line 111. The part 101 authenticates the user and then sends a call back trigger to a dial back control part 103 when the authentication of the user succeeds. The part 103 instructs a dial back execution part 102 to call the dial back number that is registered to the user. The part 102 performs the call via the circuit 112.
