SOLUTION: An input/display device 1 is composed of a CRT with a touch panel and equipped with a color input part 3 and a message part 4. Then the color input part 4 displays displays four arrays 12 of a color 11 among 16 colors on the CRT screen and also displays a button 13 having characters 'reset' at its lower end. Then combination data on four colors is matched against data of the color 11 of each color array 12 to confirm whether or not the data of the color 11 is matching and when that is confirmed, a person himself confirmation signal is outputted to a CD machine 5 and a display erasure command of a message field 14 is outputted to an image display part 23, thus completing the operation. Therefore, the illegal use of a card can be prevented by employing a color which can reduce a limited frequency.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an identification method used as a method of identifying a person when using a card or the like.

[0002]

2. Description of the Related Art Conventionally, as a method of identifying a person, an encryption method for identifying a person by inputting a plurality of numbers (personal identification numbers) is generally used. In addition, a limit number of times is set to allow re-input (re-selection) due to a number input error, and if the correct number is not input within the limit number of times, the card cannot be used.

[0003]

However, in the method based on the combination of the above-mentioned numbers, meaningless numbers are easy to forget, and simple meaningful numbers (for example, birthday, telephone number, etc.) are guessed by others. It is easy to use, and if the card is lost or stolen, the personal identification number could be easily known and could be used illegally.

Further, in the method of combination of numbers, when the person forgets the personal identification number, the number of times is exceeded while repeating trial and error, the card cannot be used, and the procedure for reissuing the card is complicated. There was no choice but to carry out post-treatment.

Therefore, the first aspect of the present invention is to provide a method for identifying a color by using a meaningless color and relaxing the limit number of times.

[0006]

In order to achieve the above-mentioned object, the color identifying method according to claim 1 of the present invention provides a plurality of color rows in which a plurality of colors are arranged, and each of the color rows is provided. The identification is confirmed when the color selection of is matched with the color designation set for the identification.

By selecting a color from the color string by the above method, the selection becomes meaningless, and the risk that the personal identification number (preset color combination) is known to others is reduced. The color identification method according to claim 2 is the color identification method according to claim 1 in which the number of times of color reselection is limited, and when the color selection is incorrect, the color identification method is set for identification. Check if the color that is close to the selected color is selected, and if the color that is close to is selected,
It is characterized in that the limit number of times is relaxed.

According to the above method, when the color selection is wrong, and when a similar color is selected, the limit number is relaxed and the selection is allowed to be repeated. This prevents the card from becoming unusable.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of an identification device using the color identification method of the present invention.

The identification device of the present invention comprises an input / display device 1 and I
The input / display device 1 is formed of a CRT with a touch panel, and the input / display device 1 is divided into a color input unit 3 and a message unit 4. The ID confirmation device 2 is connected to, for example, the CD machine 5 as an output operation unit, and is connected to the encryption database file 6 as a determination database (DB) unit. When a card is input, the CD machine 5 reads the card-specific data (card number, etc.) stored in the card and outputs an ID check signal including this data to the ID confirmation device 2. The cryptographic database file 6 stores a code number for each card (data of a color combination of four digit numbers for identification).

In the color input section 3, four columns 12 of 16 colors 11 are displayed on the CRT screen according to the image data output from the ID confirmation device 2, and the word "reset" is written at the lower end. Button 13 is displayed, and the arrangement position (XY coordinates) of each color 11 and button 13 on the CRT screen is set in advance. By touching a position corresponding to each color 11 or button 13, the XY The coordinates are displayed on the touch panel and I
The ID confirmation device 2 determines which color 11 is input to the D confirmation device 2 and which "reset" button 13 is selected.
You can understand. The row 12 of 16 colors 11 is formed by arranging similar colors in order.

In the message section 14 of the message section 4, the image data output from the ID confirmation device 2
"Please select a color.", "The color selection is incorrect. Please select again.", Or "The card cannot be used." Is displayed.

The ID confirmation device 2 is formed of a microcomputer, and has an input / output section 21 for inputting / outputting data to / from the CD machine 5 and an image in which the image data of the CRT of the input / display device 1 is preset. The data section 22 and the image data section 22
Connected to the image display unit 23 for outputting image data to the CRT of the input / display device 1, and an ID for inputting data of XY coordinates touched from the touch panel of the input / display device 1.
A database input / output unit 25 for inputting / outputting data to / from the input unit 24 and the encrypted database file 6;
It is connected to the image display unit 23, the ID input unit 24, and the database input / output unit 25, exchanges data through the input / output unit 21, inputs XY coordinate data through the ID input unit 24, and enters the database. It is composed of a judgment unit 26 that judges the identification by transmitting and receiving data via the output unit 25.

The operation of the judging section 26 will be described with reference to the flowchart of FIG. The image display unit 23 outputs the image data of the color input unit 3 stored in the image data unit 22 to the input / display device 1 (CRT), and the color column 12 and the “reset” button 13 are displayed on the CRT. It is assumed that

First, it is confirmed whether or not the ID check signal is input (step-1). If not confirmed, the limit number N is set to "3" (step-).
2) Delete the four-color combination data and the XY coordinate data, which will be described later (step-3).

When the input of the ID check signal is confirmed in step-1, the data of the card included in this signal is output to the encryption database file 6 (step-
4), the code number of the card from this cipher database file 6 (data of color combination of digit number 4 for identification)
Is input (step-5), the combination data of these four colors is stored (step-6), and a command signal for displaying "Please select a color" in the message field 14 is output to the image display section 23 (step). -7).

In response to this display command signal, the image display unit 23 outputs the image data of "Please select a color" stored in the image data unit 22 to the input / display device 1 (CRT), and the message column Displayed on 14.

Next, when the XY coordinate data by selecting the color 11 of each color row 12 is input from the touch panel of the color input section 3 (step-8), this XY coordinate data is stored (step-9), and subsequently. Confirm that the "reset" button 13 has been selected (step-10). When you confirm, XY stored
The coordinate data is erased (step-11), the process returns to step-8, and if not confirmed, it is confirmed whether all four XY coordinate data for each color row 12 are stored (step-).
12). If not confirmed, the process returns to step-8, and if confirmed, these four XY coordinate data are converted into data of color 11 of each color row 12 (step-13).

Next, the combination data of the four colors and the data of the color 11 of each color row 12 are matched (step-14), and it is confirmed whether the color data match (step-15).
Upon confirmation, a personal identification signal is output to the CD machine 5 (step -16), an instruction to erase the display of the message column 14 is output to the image display section 23 (step -17), and the processing ends.

The CD machine 5 carries out operations such as withdrawing money according to the personal identification signal. Further, the characters in the message field 14 are deleted by the image display unit 23. Of course, it is possible to use it together with the conventional numerical encryption method.

If the data do not match in step -15, a fitness calculation by fuzzy inference, which will be described later, is performed (step -18), a value n for subtracting the limited number is set (step -19), and then the limited number of times. The value n is subtracted from N (step-20), and it is confirmed whether the subtracted limited number N is 1 or less (step-21). If it is greater than 1, the image display unit 23 displays "Color selection is wrong. Please select again. "Is output to the message field 14 and the display command signal is output (step-22), and the process returns to step-11.

In response to this display command signal, the image display section 23 stores the image data of "Color selection is wrong. Please select again." It is output to the CRT) and displayed in the message column 14.

In step-21, when the limited number N is 1 or less, a command signal for displaying "Card cannot be used" in the message field 14 is output to the image display section 23 (step-23), and the CD machine 5 A signal indicating that the person cannot be confirmed is output to (step -24), and step -17 is executed.

In response to the display command signal, the image display section 23 stores the image data "Card cannot be used" stored in the image data section 22 on the input / display unit 1 (CR).
Output to T), displayed in the message column 14, and then deleted. Further, the CD machine 5 stores the unusable data in the card and returns the card.

A method of setting the value n for subtracting the limited number of times by the fuzzy inference will be described with reference to FIGS. 3 and 4. In FIG. 3, the membership function is set for each color column 12, and the color indicated by * A is the color set for personal identification on the card, and the matching value of this set color is 1. , "1""2" digit color column 12 has matching values greater than 0 for two colors on both sides, and "3""4" digit color column 12 has matching values greater than 0 for both sides. It is formed so that the value exists. That is, the first two
Regarding the color of the digit, the matching value is strict because it is unlikely to be erroneously memorized.

Next, the matching values of the color column 12 of "1""2" digits are added, and the matching values of the color column 12 of "3""4" digits are added,
The position of the center of gravity is obtained by a fuzzy operation using the membership function and the fuzzy rule shown in FIG. 4 based on the added compatible value.
0) ”,“ −1 subtraction (n = −1) ”,“ −2 subtraction (n =
-2) ". In addition, the combination of addition of compatible values is "
It is also possible to change to 1 "digit and" 2,3,4 "digit, or" 1,2,3 "digit and" 4 "digit.

According to the above fuzzy reasoning, when the selection of the color 11 is wrong, the degree of error of the color 11 is judged,
When a color similar to the color set on the card is selected on the touch panel, no subtraction is performed, the limit number N does not decrease, the color selection can be repeated, and the color is set on the card. If you select on the touch panel a color that does not at all approximate the existing color, the maximum number of times is
-2 "is subtracted, and the card becomes unusable less than a predetermined number N of times.

The operation of the above configuration will be described. First, when the user of the card inserts the card into the CD machine 5, the CD machine 5 reads the data of the card set in the card, outputs an ID check signal including this data to the ID confirmation device 2, and the ID The ID confirmation device 2 confirms the code number of this card (data of the color combination of the digit number 4 for identification) by the check signal, and displays the message "Please select a color" in the message column 14.

According to this display, the user can use each color column 12
Select color 11 for each. This color selection is 4 for the ID confirmation device 2.
If the color combination data match, a personal identification signal is output to the CD machine 5, and the CD machine 5 carries out operations such as withdrawing money.

If the color data do not match, the degree of error in the selected color is obtained by fuzzy inference, and the limit number is reset based on this degree. The message "Incorrect selection. Please select again" is displayed in the message field 14. If the limit number of times is 0, a signal indicating that the person cannot be confirmed is output to the CD machine 5, and a message "card cannot be used" is displayed in the message column 14. The CD machine 5 stores the unusable data in the card and returns the card.

As described above, by first selecting the color 11 from the color string 12, the selection becomes meaningless depending on the taste or sensitivity of the person, and the personal identification number (combined data of four colors for identifying the person). It is possible to reduce the risk that the card is easily known to others, and it is possible to prevent the card from being used illegally when the card is stolen or lost. Also, if the wrong color 11 is selected, and if an approximate color is selected, the selection can be repeated when ambiguously stored by relaxing the limit number of times. It is possible to prevent the card from becoming unusable. It is also effective for users who have poor eyesight and have difficulty in identifying numbers.

In addition, although the approximated colors 11 are arranged in order in each color column 12, even if they are not arranged in order, the approximated colors for each color 11
By registering 11 in advance, the matching value shown in FIG. 3 can be obtained. Needless to say, the membership function and fuzzy rule used for fuzzy inference can be set arbitrarily.

[0033]

As described above, according to the first aspect of the present invention, by selecting a color from the color string, it becomes a meaningless selection depending on the taste or sensitivity of the person, and the personal identification number (set for personal identification is set. It is possible to reduce the risk that the created color combination is easily known to others, and to prevent unauthorized use of the card when the card is stolen or lost. It is also effective for users who have poor eyesight and have difficulty in identifying numbers.

According to the second aspect of the present invention, when the color selection is wrong and an approximate color is selected,
By relaxing the limit number of times, it is possible to prevent the card from becoming unusable when repeated storage is allowed when the storage is ambiguous.
