Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to personal authentication,
The present invention relates to a signature verification system, a signature verification method, and a recording medium recording a signature verification program, which is suitable for determining the authenticity of a person.

2. Description of the Related Art Two-way transactions in ATMs such as banks,
Further, in recent years, it has become an important issue in sending and receiving transactions / services on the Internet due to the development of communication such as networks to authenticate whether or not the other party is the person in question. Currently, the mainstream method for such authentication is identification number authentication, but biometrics authentication such as fingerprints and iris has recently been in the limelight because it can be easily spoofed. However, fingerprints and irises have the problem that they are psychologically disgusting because they are physical information, so they can be easily input to inexpensive tablets, etc., and dynamic recognition of the person based on changes in writing pressure, speed, etc. Signatures are receiving attention.

This type of dynamic signature collates handwriting information registered in advance in a collating device with handwriting information input from an input device such as a tablet to determine whether or not the user is the person himself / herself. For example, as described in Japanese Patent Application Laid-Open No. 2000-123170, a plurality of sample signatures are registered as reference signatures, a matching value between the input signature and each reference signature is calculated, and the matching value in the space spanned by the matching values is calculated. Based on the position of the input signature, it is determined whether the signature is the original signature.

In the conventional signature verification system, since it is difficult to make a signature that exactly matches the signature of the person who is registered in advance, the level of similarity determination is set low. When imitating, there is a problem that it may be recognized as the person. An object of the present invention is to provide a signature collation method that is difficult to imitate another person in authenticating with a signature and can perform reliable personal authentication. The present invention provides a plurality of handwritten signature data and their input order or input area. The above problem is solved by determining the authenticity based on the selection information.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings. 1 to 4 show an embodiment of a signature verification system to which the present invention is applied. FIG. 1 is a system configuration block diagram in one embodiment of the present invention. In FIG. 1, reference numeral 10 is a signature data input control mechanism having an input data detection unit and an input control unit. Reference numeral 20 is a signature input screen, and 30 is a handwritten character input means of the authentication client including 10 and 20. Reference numeral 40 is an authentication device, and 50 is an internal storage device of the authentication device 40. There are a plurality of authentication clients, that is, the handwritten character input means 30, and they are connected to the authentication device 40 by a communication line.

The signature data input control mechanism 10 is a device capable of acquiring coordinate data from the signature input screen 20. The signature data input control mechanism 10 detects the signature of each individual or the input data such as personal information (name, telephone number, etc.), and detects the input area. It is to be selected. The signature data, input order data, and input area data obtained here are used as personal authentication data. Here, the input area data is data indicating which input area is selected from the plurality of input areas, and the input order data is data indicating in what order the input areas are input.

FIG. 2 shows details of the signature input screen 20. FIG. 2A is an example of the signature input screen 20. The signature input screen 2
Reference numeral 0 has a plurality of signature input areas 21, 22, 23, and 24, and handwritten characters can be input to the areas 21 to 24, and the input handwritten characters are displayed. Figure 2 (b)
Is an example in which a name, a system setting character string, a telephone number, and a date of birth are entered in each signature input area 21 to 24. Figure 2
(c) is an example of a table created by the input data registration process. The input area, input order, and signature are registered. In the input area column, the identification numbers 21 to 24 of the signature input area
However, in the input order column, the input sequences 1 to 4 are registered, and in the signature column, the register address in which the image image of the input signature is stored is registered.

With reference to FIG. 2, in addition to the input from the touch panel, the signature can be input from the monitor screen, and at this time, conversational exchange is possible.
For example, the system outputs a voice message "Please input the first one". (Only the person himself / herself knows the input order and the input area, and since this is collated, what is the first and which area is to be input are not taught.) In this embodiment, 4 of the input areas 21 to 24 However, the number may be increased depending on the situation such as increasing the authentication accuracy.

The authentication device 40 includes an input data check unit (verifying unit) 41 and an input data registration unit (registering unit) 42.
Authentication processing is performed using the data registered in the internal storage device (storage means) 50. The internal storage device 50 stores signature data in the personal identification signature data holding unit 51, input order data in the personal identification input order data holding unit 52, and input area data in the personal identification input area selection data holding unit 5.
Hold at 3. The signature data (here, character string data) registered in the personal identification signature data holding unit 51 of the internal storage device 50 is a character string previously input by the authentication client person (authenticatee) from the handwritten character input means 30. It is registered in the holding unit 51 by the processing of the input data registration unit 42. The registration in the personal identification input order data holding unit 52 and the personal identification input area selection data holding unit 53 is performed after the characters input from the handwritten character input means 30 are recognized by the input data detection unit and then input data registration unit 42. You may perform by the process of. Each of the above data holding units 51, 5

The above-mentioned input data check unit (collating means) 41 includes the signature data, the input order data, transmitted from the signature data input control mechanism 10 of the handwritten character input means 30 of the authentication client,
The input area data is collated with the personal identification data stored in the storage device 50.

Next, an example of an input data registration processing procedure by the present signature verification system (input data registration unit 42) will be described with reference to the flowchart of FIG. Step S501
Then, in the input data registration unit 42, the input signature data is acquired from the signature data input control mechanism 10, and step S5
In step 02, the input area selection data is acquired in step 02.
In step S504, the input order data is acquired, and in step S504, the principal confirmation signature data holding unit 51, the principal confirmation input order data holding unit 52, and the principal confirmation input area selection data holding unit 53.
To register respectively. The operator or the system can allocate and apply the input area selection data and the input sequence data.

With reference to FIG. 5, the registered contents (table) should not be shown to anyone (the person himself).
Securely protect authentication data. If the person forgets, register again. In this case, before registration, you will be asked to present something that can authenticate you, such as a driver's license, to authenticate yourself. If the error message is repeated three times, authentication may be disabled unless the person re-registers.

Next, the input data check processing procedure (verification processing procedure) by the present signature verification system (input data check unit 41) will be described with reference to the flowchart of FIG. FIG. 6 shows a pattern (Pattern 1) for authenticating the person by matching the input area and the signature. When the input order is used instead of the input area for the determination, the determination is performed by the same flow. In step S201, the number of signatures (here, input character strings) input from the signature data input control mechanism 10 is acquired, and in step S202, the number-of-identity-signature data registered (stored) in the internal storage device 50 in advance is used. The number of input signatures obtained in step S201 is collated. Step S20
3 is a true / false determination in the number of input signatures. Step S
If the input signature is determined to be false in 203, a principal confirmation error message is output in step S210 and the process ends. On the other hand, if it is determined to be true, the signature data input from the signature data input control mechanism 10 is acquired in step S204, and N signature input screens 20 (N is 2
Step S20 of acquiring input area data that specifies the input area selected in the signature input area of (the above integer)
Do 5.

In step S206, the input signature data obtained in step S204 is collated with the personal identification signature data registered in the personal identification signature data holding section 51 of the internal storage device 50. Step S207 is a true / false determination in the input signature data. If the input signature is determined to be false in step S207, a principal confirmation error message is output in step S210, and the process ends. On the other hand, when it is determined to be true, the input area selection data obtained in step S205 and the input area selection data for personal identification registered in the personal identification input area selection data holding unit 53 of the internal storage device 50 are stored. The matching step S208 is performed.
Step S209 is a true / false determination in the input area selection data. If the selection of the input area is determined to be false in step S209, a personal identification error message is output in step S210 and the process ends. On the other hand, if it is determined to be true, the process returns to step S204 to obtain the next signature data, and the signature data is similarly determined for the number of times of the personal identification signature number data in the internal storage device 50. If the authenticity of all the signatures in the internal storage device 50 and the verification data for identification is true, the person is authenticated.

FIG. 7 is also a flowchart of the input data check processing procedure. FIG. 7 shows a pattern (Pattern 2) for authenticating the person using the input order and the input area.
The difference is that the input order is confirmed as compared to the step. In FIG. 7, the number of signatures (here, input character strings) input from the signature data input control mechanism 10 is acquired in step S301, and step S302 is the internal storage device 5.
The personal identification signature number data registered (stored) in 0 is compared with the input signature number obtained in step S301. Step S303 is a true / false determination based on the number of input signatures. If the input signature is determined to be false in step S303, a principal confirmation error message is output in step S313, and the process ends. On the other hand, if it is determined to be true, step S304 of acquiring the signature data input from the signature data input control mechanism 10, the signature input screen 2
Step S305 is executed to acquire data that specifies the input area selected in the N signature input areas of 0 (N is an integer of 2 or more).

In step S306, the input order data of N (N is an integer of 2 or more) signature data input from the signature input screen 20 is acquired, and in step S307, the input signature data obtained in step S304 and internal storage are acquired. The identity verification signature data in the device 50 is collated, and step S308
Is the authenticity determination in the input signature. Step S308
If the input signature is determined to be false in step S, step S
A personal identification error message 313 is issued and the process is terminated. On the other hand, when it is determined that the signature is a true signature, the input sequence data obtained in step S306 is collated with the personal confirmation input sequence data registered in the personal confirmation input sequence data holding unit 52 of the internal storage device 50. Perform step S309. Step S310 is a true / false determination in the input order. If it is determined in step S310 that the selection of the input order is false, a personal identification error message is output in step S310 and the process ends. On the other hand, if it is determined to be true, step S311 is performed in which the input area selection data obtained in step S305 is compared with the person confirmation input area selection data in the internal storage device 50. Step S312 is true / false determination in the input area selection data. If the selection of the input area is determined to be false in step S312, a personal identification error message is output in step S313, and the process ends. On the other hand, if it is determined to be true, the process returns to step S304 to acquire the next signature data, and the determination of the signature data is similarly performed for the number of the personal identification signature number data in the internal storage device 50.
If the authenticity of all the signatures in the internal storage device 50 and the verification data for identification is true, the person is authenticated.

Here, even if the signature data and the data of the input area / sequence are obtained one by one from the authentication client 30 in a time series and sequentially collated, the signature data input control mechanism 10 sets the combination of the signature data and the input area / sequence. Is generated as a record and transmitted to the authentication device 40.
May be a method of sequentially matching records in the table. In this case, since the number of rows in the table indicates the number of signature data, it is possible to easily perform the authentication determination based on the number of input data by determining the number of rows.

FIG. 3 is a block diagram of a system configuration according to another embodiment of the present invention, in which authentication using a single character (hereinafter,
It is called single character judgment. ) Shows the system configuration. In FIG. 3, 60 is a signature data input control mechanism similar to that of FIG.

80 is an authentication client (authenticatee) including 60 and 70
Is a means for inputting handwritten characters. 90 is an authentication device, 100
Is an internal storage device of the authentication device 90.

The signature data input control mechanism 60 performs the same processing as that of the signature data input control mechanism 10. The signature data, the input character number data, and the character input order data, which are the set of single characters obtained here, are used as the personal authentication data. FIG. 4 shows details of the signature input screen 70. Figure 4
(A) is the detailed drawing. The signature input screen 70 has a plurality of single character input areas 71 in which one character can be input, a clear button 72, and a send button 73, and sequentially acquires the single character data input in each single character input area 71 of the signature input screen 70. Then, it is displayed on the same screen 70. In this example, "Ichiro Suzuki" is input in the order of "bell", "ro", "tree", and "one". After inputting all single characters and confirming, send button 7
In step 3, the data is transmitted to the input data registration unit 92 of the authentication device 90.
In case of erroneous input, the clear button 72 is used to erase. The input data registration unit 92 registers the transmitted single character data. FIG. 4B is an example of a table created by the input data registration process. Input order, signature, and recognition character are registered. "Bell", "tree", "one", "ro" is 1,
The third, fourth and second are entered. The register address in which the image image of the input signature is stored is registered in the signature field. In the recognition character field, the signature data input control mechanism 60 is provided with a handwritten character recognition means having cells for recognizing individual characters, and the characters recognized by the character recognition means are registered, but this field is not necessary. .

The authentication device 90 includes an input data check unit 9
1 (collating means) and an input data registration unit 92 (registration means), and performs an authentication process using the data registered in the internal storage device 100. The internal storage device 100 stores the signature data in the personal identification signature data holding unit 101, the input character number data in the principal confirmation input character number data holding unit 102, and the input order data in the principal confirmation input order data holding unit 103. . The signature data (single character data in this case) registered in the personal identification signature data holding unit 101 of the internal storage device 100 is a character string previously input by the authentication client person (authenticatee) from the handwritten character input means 80. By the processing of the input data registration unit 92, individual characters separated by character or input by the system operator as an image are processed.
It is registered in the holding unit 101. Registration in the personal identification input character number data holding unit 102 and the personal identification input order data holding unit 103 recognizes the characters input from the handwritten character input means 80 and the individual characters provided in the signature data input control mechanism 60. It may be performed by the process of the input data registration unit 92 after the character is recognized by the handwritten character recognition means having a cell. For example, the personal identification signature data holding unit 101 and the personal identification input sequence data holding unit 10
3 may be configured in a table format as shown in FIG. 4B, and the personal identification input character number data holding unit 102 may be configured by a data holding register. The input data check unit (collating means) 91 collates the signature data, the input order data, the input character number data transmitted from the signature data input control mechanism 60 with each personal identification data stored in the storage device 100. I do.

Next, the input data check processing procedure using the single character determination will be described with reference to the flowchart of FIG. In the single character determination pattern (Pattern 3), the single character data of the signature input from the signature data input control mechanism 60 in step S401 is acquired, and step S402
Obtain the total number of characters input in step S403
The input sequence data of the character data of N characters (N is an integer of 2 or more) input from the signature data input control mechanism 60 is acquired. In step S404, the input character data obtained in step S401 is compared with the personal identification signature data (single character data) in the personal identification signature data holding unit 101 of the internal storage device 100. In step S405, the authenticity of the input character data is determined. When the character data is determined to be false in step S405, step S41
At 1, a personal identification error message is output and the process ends.
On the other hand, if it is determined to be true, step S40
In step S406, the character input sequence data obtained in step 3 is compared with the personal confirmation input sequence data in the personal confirmation input sequence data holding unit 103 of the internal storage device 100.
Step S407 is a true / false determination in the input order.
If the selection of the input order is determined to be false in step S407, a personal identification error message is output in step S411, and the process ends. On the other hand, if it is determined to be true, step S408 is performed to determine whether the signature input is completed. When the input is not completed, the next character string is similarly determined. If the input is completed, step S
The step S409 of collating the input character number data obtained in 402 with the personal identification character number data in the personal identification input character number data holding unit 102 of the internal storage device 100 is performed. Step S410 is a true / false determination based on the input character number data. If the number of input characters is determined to be false in step S410, a personal identification error message is output in step S411 and the process ends. On the other hand, if it is determined to be true, the user is authenticated.

As described above, the signature can be authenticated by processing one character string as a set of single characters. When this is applied to a plurality of signature data, the above processing may be performed for each signature. Further, the handwritten character input means may be provided with a wireless communication means, and the handwritten character input may be input to the authentication device through communication by the wireless communication means. If you do this,
It is convenient because a mobile terminal can be applied and it can be easily carried. It is also possible to program the signature verification method of the present invention for a computer and record the program in a recording medium. The order of collating the signature data, the input character number data, the input area data, and the input order data in the above embodiment can be exchanged, and a signature (here, a signature) other than a character string or a single character can be used as the signature. It is also possible to use figures and figures. Other,
It is obvious that various modifications can be made to the embodiments without departing from the spirit of the present invention.
