Authenticating apparatus for executing user authentication
First Claim
1. An authenticating apparatus comprising a controller configured to expand a control program into random access memory to function as:
- an authentication-processing unit that executes user authentication by comparing an entered password with a preset password;
an input-receiving unit that receives a sequence of characters of the entered password and at least one dummy key inserted before a character in the sequence of characters, wherein the at least one dummy key is not considered part of the sequence of characters such that, in the comparison performed for the user authentication, the at least one dummy key is not compared with the preset password; and
a dummy-input-notification unit that causes a notification at an input timing during said receiving of the sequence of characters;
whereinthe notification comprises at least one vibration;
the input-receiving unit is configured to receive the at least one dummy key after the notification is caused and before receiving the character in the sequence of characters;
the input timing indicates the character in the sequence of characters before which the at least one dummy key is to be inserted;
the number of said at least one vibration indicates the number of dummy keys which are required to be inserted to provide said at least one dummy key; and
the authentication-processing unit, together with comparing the entered password with the preset password, compares the number of dummy keys received as said at least one dummy key with the number of dummy keys which are to be inserted, and when the entered password and the preset password match, and the number of dummy keys received as said at least one dummy key match the number of dummy keys which are required to be inserted, determines that authentication is successful, and when the entered password and the preset password do not match, and/or the number of dummy keys received as said at least one dummy key and the number of dummy keys which are required to be inserted do not match, determines that authentication is failure.

Abstract
Provided is an authenticating apparatus that by a simple method improves security when entering a password. The authentication-processing unit executes user authentication by comparing an entered password that is entered with a preset set password. The input-receiving unit receives dummy keys while the entered password is entered that are not compared with the set password. The dummy-input-notification unit notifies using vibration of dummy key input timing and the number of times input is required. The authentication-processing unit, together with comparing the entered password with the set password, compares the number of times dummy keys are inputted with the number of times input is required. When the entered password and the set password match, and the number of times dummy keys are inputted and the number of times input is required match, authentication is determined to be successful.
