Abstract
A system for registering a password derivation pattern for deriving a password to be used in user verification includes a terminal device and a server. The terminal device is configured to display a presentation pattern, the presentation pattern including a plurality of elements, each of the plurality elements being assigned with predetermined characters, so as to cause the user to input a character assigned to a specific element with respect to the presentation pattern. The server is connected with the terminal device via a communication channel. The server is configured to repeat the process of displaying a new presentation pattern until the password derivation pattern is specified based on the character inputted by the user. The server is configured to store the specified password derivation pattern.
