JPH0729005A - Personal identification system - Google Patents

Abstract

PURPOSE:To provide a personal identification system which prevents the illegal use of a personal resource and whose security is higher in a computer system. CONSTITUTION:At the time of using the system, a user reads an ID card by a pen input system 5, sets an input condition such as the color and thickness of a pen and inputs a sign and a mark by an input pen. The inputted sign (mark) is recognized by a pattern recognition means 6, a write order recognition means 7 and an input condition recognition means 8 as respective data, and an ID number and sign (mark) information are transferred to a host system 9. The host system 9 searches sign (mark) information which is previously registered in a user data base 14 with card ID as a key, data-collates sign (mark) information having same ID, a pattern, a write order and the input condition by a pattern collation processing part 10, a write order collation processing part 11 and an input condition collation processing part 12. Only when they coincide, the use of the system is permitted.

Description

Detailed Description of the Invention

[0001]

[Industrial field of application] The present invention relates to a personal authentication system for determining whether or not an input signature or mark is of a person who is registered in advance.

[0002]

2. Description of the Related Art A conventional method is, for example, Japanese Patent Laid-Open No. 3-24.
As described in Japanese Patent No. 4086, as a method of authenticating a person, a signature handwriting or a writing pressure at the time of writing a signature is used.

[0003]

Currently, a credit card, a check, a traveler's check, and the like use a signature as one of means for authenticating an individual, but these must have a signature on the medium itself. Therefore, in the case of personal identification by handwriting of the related art, there is a problem that if the handwriting is lost, the handwriting is imitated so that it may be illegally used by another person.

Further, in the case of the personal authentication using the writing pressure of the conventional technique, there is a problem that the physical condition of the person or the inclination of the pen may cause an erroneous recognition.

An object of the present invention is to solve such problems and provide a personal authentication system with higher security.

[0006]

The above object is to provide a pen input system with means for recognizing a pattern and a writing order of an input sign or mark, and to input data input from the pen input system to a pattern or a writing order. It is determined whether or not the entered signature or mark belongs to a pre-registered person by transferring it to a host system equipped with a processing unit for collating and comparing the data with the data registered in the database in advance. It is achieved by having a function.

[0007]

As described above, according to the present invention, by using the signature and mark patterns and the writing order as the personal identification method, it is possible to create a unique cipher that only the registered person can write. For this reason, if this authentication system is adopted in application fields where cards are used, such as cash cards and credit cards, even if a signature or mark is written on the card, it cannot be imitated by anyone, so It cannot be used illegally. Further, not only a signature but also a mark such as a figure can be registered, so that anyone can easily register and use it.

[0008]

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram of a personal identification system to which the present invention is applied. In FIG. 1, the registration pen input system 1 uses a pattern recognition means 2 for recognizing a pattern of a sign or a mark input from an input pen, a writing order recognition means 3, and a color or thickness of the pen. The input condition recognition means 4 recognizes the contents that can be selected on the input screen. Similarly, the pen input system 5 used as a general use system includes a pattern recognition means 6, a writing order recognition means 7, and an input condition recognition means 8.
It is composed by.

The host system connected to the pen input system further includes a user database 14 for storing sign (mark) information corresponding to a user ID, a control unit 13 for the user database 14, data input by a user, and the user in advance. A pattern matching processing unit 10 for matching whether or not the data registered in the database match, and a writing order matching processing unit 1
1 and the input condition collation processing unit 12.

When the user registers the pen input system 1,
Read the D card. Next, input conditions such as the color and thickness of the pen are set on the input screen, and a signature or mark is input with the input pen. The input signature or mark is used for the pattern recognition unit 2, the writing order recognition unit 3, and the input condition recognition unit 4.
Are recognized as respective data by. The pen input system 1 sends the ID number and signature (mark) information to the host system 9. The host system 9 stores the card ID and signature (mark) information in the user database 14.

The user causes the pen input system 5 to read the ID card when using the general use system. Then, similarly, input conditions such as the color and thickness of the input pen are set on the input screen, and a signature or mark is input by the input pen. The inputted signature or mark is recognized as respective data by the pattern recognition means 6, the writing order recognition means 7 and the input condition recognition means 8. The pen input system 5 sends the ID number and signature (mark) information to the host system 9. The host system 9 searches the file using the card ID as a key, reads the signature (mark) information registered with the ID to the database control unit 13, and the pattern (writing order) and the input of the signature (mark) transferred with this. The conditions are matched by the pattern matching processing unit 10, the writing order matching processing unit 11, and the input condition matching processing unit 12, respectively, and the use of the general use system is permitted only when they match.

[0013]

As described above, according to the present invention, a signature or mark pattern can be used as a means for personal identification.
By using the stroke order, it is possible to prevent unauthorized use by recognizing habits and shapes that can only be written by the registered person and the pen input system can realize a more secure personal authentication system. You can
