Abstract
PURPOSE:To unable an outsider to use a password switching system even in case the outsider intercepts and uses by stealing the contents of communication of a regular system user, by calculating the next password with use of a system end message every time the user uses the system and switching the passwords. CONSTITUTION:A user gives an indication to a central computer 1 via a terminal equipment 9 to show the end of application of the on-line processing service. Thus a CPU 2 performs the end processing and outputs an end message. At the same time, the CPU 2 sends the end message to a password recalculating computer 3 for calculation of the next password. While the end message is stored in an end message memory 7. The calculated password is stored in a password memory 5 as the next password together with user identifying information. The user of the equipment 9 receives the end message from a host system and prepares for application of the next on-line processing service by means of its own password recalculation formula.
