Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic authentication input device used in a terminal of an information processing device. In particular, the present invention relates to an input device for authenticating an operator or an auditor of a financial service terminal or automated financial machine.

〔overview〕

The present invention provides an electronic authentication input device for identifying terminal users, in which each user carries a unique authentication device (equivalent to a stamp), and the authentication device electronically transmits the user's authentication data. When used, the authentication data is converted into a signal to drive a light-emitting element, which is received by the light-receiving element of the authentication receiver attached to the terminal, and the authentication data signal is detected and stored in advance. This provides an electronic authentication input device whose operation is similar to that of a seal stamp method, by comparing the information with the existing authentication data and performing authentication.

[Conventional technology]

Conventionally, electronic authentication input devices and methods include those that use mechanical keys such as operator keys and auditor keys on electronic keyboards, and those that use the logic of operating a keyboard to enter a PIN number for authentication. There are some methods that use conventional methods, some that use ID cards such as magnetic cards or optical cards, and some that use a combination of these methods.

[Problem that the invention seeks to solve]

However, these conventional authentication devices and methods require the use of a mechanical key, or the manual entry of a personal identification number, so seals have long been used as an authentication method in Japan. This method is different from the method of stamping or stamping a seal and confirming the stamp, so the authentication operation and confirmation method of the authentication device and method had the disadvantage that Japanese people who are accustomed to the stamp method were not familiar with it.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic authentication input device that is similar to the conventional seal stamping method and can perform authentication without causing any discomfort.

[Means for solving problems]

The present invention includes an authenticator that stores individual authentication data of a user, reads out the authentication data during use, converts it into a signal, and drives a light-emitting element, and a light-receiving element that detects the authentication data signal and stores it in advance. The present invention is characterized by comprising an authentication acceptor that performs authentication by comparing the authentication data with the authentication data.

[For production]

Each user using one terminal carries a separate authenticator. When using a terminal, this authenticator is pressed against the authentication receiver of the terminal, just like pressing a stamp, and the user is identified to the terminal.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. 1 is an authentication device, which can also be called an electronic seal, which has authentication data for each person and is carried by each person. Reference numeral 2 denotes an authentication reception device, which is installed in a financial service terminal or a financial automatic machine.

The authenticator 1 includes a memory 11 for storing a control program, a memo 2 for storing authentication data, and a central processing unit (CPU) 13.
It is connected to memories 11 and 12. 14 is a serial parallel converter, central processing unit 13, memo January 1.1
2 and sends the converted signal to the light emitting diode 15 to drive the light emitting diode 15. The authenticator 1 has a built-in drive battery 16 for driving a circuit for transmitting these authentication data.

The authentication receiver 2 includes a signal detector 18 having a light receiving diode 17. The data from the signal detector 18 is sent to the authentication verifier 21
, and is sent to the authentication data processing unit 19 consisting of the memory 20 and processed.

Next, the operation of the embodiment will be described.

When the authenticator 1 is activated, the control program is read from the memory 10 to the central processing unit 13. According to the control program, the authentication data stored in the memory 11 is read out and sent to the serial/parallel converter 14.

The serial/parallel converter 14 converts the sent authentication data into a serial signal and drives the light emitting diode 15. The light emitting diode 15 converts this signal into light and sends it to the light receiving diode 17 of the authentication receiver 2.

When the authentication acceptor is driven, the light receiving diode 17 receives an optical signal from the light emitting diode of the authenticator 1 and converts it into an electrical signal. The signal detector 18 detects the authentication data signal from the authenticator 1 through photoelectric conversion of the light receiving diode 17,
The signal is sent to the authentication data processing section 19. The authentication data processing unit 19 passes the authentication data stored in advance in the memory 20 and the input authentication data to the authentication collation device 21.
to identify the person who affixed the seal (authentication 3).

FIG. 2 is a longitudinal sectional view illustrating the coupling relationship between the authenticator 1 and the detection portion of the authentication acceptor 2. As shown in FIG. FIG. 2(a) shows just before the -1 stamp is stamped, and FIG. 2 (bl indicates the stamp is being stamped).

In FIG. 2, 15 is a light emitting diode built into one end of the authenticator 1, and 17 is a key 2 of the authentication receiver.
This is a light receiving diode built into 4. key 24
is for push-in type activation 2. The key 24 can be installed as a detection part of the authentication acceptor 2, for example, on a part of the keyboard of a financial business terminal or separately from the keyboard.

When the authentication key 1 is pressed against the key 24 of the authentication receiver, the key 24 is turned on, the light emitting diode 15 and the light receiving diode 17 are activated, and the two are optically coupled. By optically coupling the authenticator 1 and the detection part of the authentication acceptor 2, the authentication data of the authenticator 1 is
The information is transmitted between the light emitting diode 15 and the light receiving diode 17, and verification and authentication can be performed by the authentication receiver 2.

When authentication is completed and the authenticator 1 is released from the key 24 of the authentication acceptor, the key 24 is raised and the switch is automatically turned off, and the optical coupling between the authenticator 1 and the detection portion of the authentication acceptor 2 is released.

The authentication data stored in the memory 11 of the authenticator 1 can be various types such as numerical data of a password, bit data of an encrypted seal impression, etc. In case of numerical data of PIN number,
The difference is that the data length is shorter than the bit data method for seal impressions.

As an example of authentication data, FIG. 3 shows an example in which a seal imprint is converted into bits as image data.

In this example, the seal impression "Saito" is divided into n rows vertically and m columns horizontally, and the seal impression information of the divided portions is converted into data 1 to N (nXm) in 8-bit units. The divided portions can be converted into data by encoding them based on the brightness of the divided portions or the direction in which the seal impression line cuts the divided portions. The information of each of these divided portions is configured into frames with data lengths 1 to N. And data 1~
A start of text) (ST father) code is added to the beginning of N, an end of text (ETX) code is added to the end, and a checksum code of the checksum is added after the end of text I- (ETX) code to form the whole. The data consists of:

Authentication data is stored in the memory 11 of the authenticator 1 in this data structure, and when the authenticator I and the authentication receiver 2 are driven, the data of the authenticator is transferred to the authentication receiver by the light emitting diode 15 and the light receiving diode 17. The authentication data processing device compares the authentication data with separately stored authentication data to perform authentication.

C Effects of the Invention] As described above, the present invention allows the authentication device to store the user's unique seal or signature, and to authenticate the user by pressing the key on the authentication receiver with the authentication device. Users can use the system with the same feeling as pressing a seal, and there is no discomfort with conventional seal authentication methods. Moreover, it has the effect of not requiring any troublesome operations such as pressing a password.
