Authentication apparatus, authentication method, and authentication system
First Claim
1. An authentication apparatus comprising:
- a user information registration processing circuit that registers, for each user, user identification information, reference identification information that constitutes a reference, and a selection sequenced identification indicator string having a plurality of selection identification indicators that are selected from a plurality of identification indicators and a sequence of the selection identification indicators; and
a user authentication processing circuit that executes a user authentication by the use of a password and the user identification information, whereinthe user authentication processing circuit produces a random identification indicator string by arranging the plurality of identification indicators at random;
the user authentication processing circuit calculates, for each of the selection identification indicators of the selection sequenced identification indicator string, a position value that indicates the position of the respective selection identification indicator in the random identification indicator string relative to the reference, thereby providing a plurality of position values;
the user authentication processing circuit creates the password as a value by arranging the plurality of position values based on the order the respective selection identification indicators occur in the sequence of the selection identification indicators, thereby providing the password as a sequence of the position values;
when a job execution requirement is received, the user authentication processing circuit verifies a user as proper based on whether the user inputs the password, thereby providing the user authentication;
when the user authentication processing circuit verifies the user as a proper user, the authentication apparatus executes the job; and
when the authentication apparatus is operated and the user identification information is inputted, the user authentication processing circuit executes the user authentication by the use of the inputted user identification information.

Abstract
Provided is an authentication apparatus easily realizing a one-time password system ensuring the security of a password without new equipment. The apparatus includes a user information registration processing circuit and a user authentication processing circuit. The user information registration processing circuit registers user identification information, reference identification information constituting a reference, and a selection sequenced identification indicator string having selection identification indicators selected from identification indicators and a sequence of these indicators for each user. The user authentication processing circuit executes a user authentication using a password determined by calculating the positions of the selection identification indicators of the selection sequenced identification indicator string from the position of an identification indicator of a random identification indicator string where the identification indicators are arranged at random that corresponds to the reference identification information into the sequence of the selection identification indicators and the user identification information.
