ABSTRACT:
In personal identification systems which compare passwords in a verification computer to identify a user, successive passwords are generated, or retrieved from a stored list in the verification computer in response to each entry of a public username into the verification computer. A user device carried by the user retrieves the next successive password from a stored list in response to a command from the user and displays the password. The user then reads this password and offers it to the verification computer via a keyboard entry to be compared with the password already generated or retrieved in response to the username (the expected password).
