Abstract

A customer authentication system that has: body feature information generation means for quantizing a body feature of a customer to generate body feature information; encrypted information generation means for encrypting the body feature information to generate encrypted information; a portable terminal for storing and maintaining the encrypted information; and a customer authentication device for decoding and collating the encrypted information received from the portable terminal and the encrypted information displayed on the portable terminal.

second decoding means for reading the encrypted information, displayed on a screen of the portable terminal, from the screen and decoding the encrypted information to generate second decoded information, and wherein

the customer authentication device collates the first decoded information with the second decoded information and, when the collation result is that the first decoded information is in agreement with the second decoded information, the customer authentication device authenticates the customer as a genuine customer.

5. The customer authentication system according to claim 1, 2, 3, or 4, wherein the body feature of the customer is a fingerprint pattern of any finger of the customer.

2. A customer authentication system comprising:

body feature information generation means for quantizing a body feature of a customer to generate body feature information;

a portable terminal; and

a customer authentication device, wherein

the portable terminal comprises

encrypted information generation means for permitting the input of the body feature information and encrypting the body feature information to generate encrypted information,

first storage means for storing the encrypted information, and

display means for displaying the encrypted information on a screen, and wherein

the customer authentication device comprises

second storage means for receiving and storing the encrypted information through a communication line,

reading means for reading an image of the encrypted information displayed on the display means in the portable terminal to generate read information,

decoding means for decoding the encrypted information stored in the second storage means to generate first decoded information and, in addition, decoding the read information to generate second decoded information, and

collation means which collates the first decoded information with the second decoded information and authenticates the customer as a genuine customer when the collation result is that the first decoded information is in agreement with the second decoded information.

3. A customer authentication system comprising:

first body feature information generation means for quantizing a body feature of a customer to generate first body feature information;

encrypted information generating means for encrypting the first body feature information to generate encrypted information;

second body feature information generation means for quantizing a body feature of the customer to generate second body feature information; and

a customer authentication device, wherein

the customer authentication device comprises

decoding means for receiving the encrypted information from the encrypted information generation means through a communication line and decoding the encrypted information to generate decoded information and

collates the second body feature information with the decoded information and authenticates the customer as a genuine customer when the collation result is that the second body feature information is in agreement with the decoded information.

4. A customer authentication system comprising:

first body feature information generation means for quantizing a body feature of a customer to generate first body feature information;

encrypted information generation means for permitting the input of the first body feature information and encrypting the first body feature information to generate encrypted information;

second body feature information generation means for quantizing a body feature of the customer to generate second body feature information; and

a customer authentication device, wherein

the customer authentication device comprises

storage means for receiving the encrypted information through a communication line and storing the encrypted information,

decoding means for decoding the encrypted information stored in the storage means to generate decoded information, and

collation means which collates the second body feature information with the decoded information and authenticates the customer as a genuine customer when the collation result is that the second body feature information is in agreement with the decoded information.

6. A method for customer authentication, comprising the steps of:

providing a customer authentication system comprising body feature information generation means, encrypted information generation means, a portable terminal, and a customer authentication device;

quantizing a body feature of a customer in the body feature information generation means to generate body feature information;

encrypting the body feature information in the encrypted information generation means to generate encrypted information;

displaying the encrypted information in the portable terminal on a screen; and

receiving the encrypted information in the customer authentication device through a communication line, reading an image of the encrypted information displayed on the portable terminal to generate read information, decoding the read information to generate first decoded information, decoding the received encrypted information to generate second decoded information, collating the first decoded information with the second decoded information, and authenticating the customer as a genuine customer when the collation result is that the first decoded information is in agreement with the second decoded information.

10. The method for customer authentication according to claim 6, 7, 8, or 9, wherein the body feature of the customer is

a fingerprint pattern of any finger of the customer.

11. A control program for carrying out the method for customer authentication according to claim 6, 7, 8, or 9 in a computer.

7. A method for customer authentication, comprising the steps of:
