Abstract

PURPOSE: To minimize an intercepted password code to be tentative damage by forming a part of the password to be a variable value being a present parameter fluctuated with the elapse of time to decrease the number of digits of the pass work to be stored by the user.
CONSTITUTION: The password code consists of fixed digits D1, D4 and variable digits D2, D3, the fixed digits D1, D4 are set by the user, and any present value of a month parameter P1, a day parameter P2 and an hour parameter P3 predetermined by the system is set as the variable digits D2, D3. When the user applies the service request from a transmission section 1 at 1:15 pm, the user inputs '9130' as the password code. The password code is sent through a telephone line 2 and received by a reception section 3 of the controller 4. The reception section collates the fixed digits in a way similar to a conventional method and the variable digits of the password code depending on the present time of a timer 6.
