2. Description of the Related Art When a user uses a service of a service company, the service company performs authentication in order to confirm that the user who intends to use the service is who he / she is. As the authentication method, for example, a method of using a personal identification number, a method of using a signature, a method of using a seal, a method of using an ID code (a small communication device that transmits or receives an ID code to a user device in a contactless manner), etc. are used. There is. The method of using a personal identification number is used, for example, when withdrawing cash from a bank account using a cash card. When the user withdraws cash, the ATM of the bank
Insert the cash card into the card slot of the (cash dispenser) and enter the PIN code. The ATM sends the card information (for example, ID) read from the cash card and the personal identification number input by the user to the authentication center. The authentication center is based on a database including the personal identification number input to the ATM and the read card information, and the correspondence relationship between the card information stored in the storage means and the personal identification number.
Authenticate. The method using a signature is used, for example, when paying for a product using a credit card. If the user pays with a credit card,
Sign the product purchase slip. The merchandise seller authenticates by comparing the signature on the merchandise purchase slip with the signature on the credit card. The method using a seal is used, for example, when withdrawing cash from a bank account using a bankbook. When withdrawing cash from a bank account using a bankbook, the user stamps a cash withdrawal sheet using a seal. The bank authenticates by comparing the stamp imprinted on the cash withdrawal sheet with the stamp registered in advance. The method using the ID code is, for example,
It is used to prevent unauthorized use of user equipment used by the user. In this method, the same ID code is stored in a tag carried by the user (a card member with a transmission / reception function, etc.) and a user device used by the user (for example, a mobile phone). Although the tag can be used by connecting it to the user equipment, it is often used as a wireless tag. The user device collates the ID code transmitted from the tag with the ID code stored in itself, and releases the use restriction of the user device if they match (outputs a use permission signal).
To do. Further, as another authentication method for confirming that the user is who he / she is, a method is known in which biometric information unique to each person (voiceprint, fingerprint, palmprint, retina pattern, image of a face, etc.) is used. In this authentication method, the biometric information of the user is read by the biometric information reading device, and the biometric information read is collated with the biometric information registered in advance to perform the authentication. Since this authentication method uses biometric information unique to each person, the authentication accuracy is high.

[0003]

[Problems to be Solved by the Invention] Conventional identification methods for identifying an individual by using a personal identification number, a signature, a seal or an ID code are the ones who use a cash card, those who use a credit card, and those who use a passbook. Even if the person carrying the tag storing the ID code is not the original user, the user may be authenticated as the correct user. For example, user equipment (eg, cash card)
If the information such as a stamp or a seal is lost or stolen, or the information such as a personal identification number, a signature or an ID code is stolen or leaked, the user device is illegally used. In addition, a conventional personal identification method for performing personal identification based on biometric information requires a biometric information reading device (for example, an imaging unit), a biometric information processing device (for example, an image processing device, a large-capacity storage device), or the like. , The cost of the entire system becomes high. Further, when a finger is scratched or an eye disease occurs, the fingerprint or the retina pattern may change, and the authentication accuracy may decrease. Further, when the retinal pattern is used, it is necessary to bring the eye to the measurement position, which is troublesome. Also, when using a fingerprint, it is necessary to bring the finger into contact with the fingerprint reader,
There is psychological discomfort for those who like cleanliness. Therefore, an object of the present invention is to provide a low cost and highly reliable personal identification method and personal identification device.

3) "7", 4th line (y = 4) is "1", 5th line (y =
5) is "2", the 6th line (y = 6) is "6", ...
., The reference information that the 16th line (y = 16) is "0" is stored. Alternatively, as shown in FIG. 6, the original information AB
The first column (x = 1) of the bitmap information “a” is “0”, the second column (x = 2) is “0”, and the third column (x = 3)
Is "3", the fourth column (x = 4) is "4", the fifth column (x =
5) is “3”, the sixth column (x = 6) is “3”, ...
., The reference information that the 16th column (x = 16) is “0” is stored. The total number of bit data of “1” in each column and each row of bitmap information may be stored as the reference information. Further, the total number of bit data of “0” may be stored as the reference information. Alternatively,
The total number of bit data that is “1” and the total number of bit data that is “0” may be stored. The bit line of the bitmap information of this embodiment corresponds to the "predetermined line" of the present invention.

The user portable device 10a transmits the first information A stored in the storage means 11a by the method described above. If position information is added to the first information A as shown in FIG. 7, the first information A1 to which the position information is added is transmitted. Processing means 23a of the user device 20a
When the communication unit 21a receives the information, the unit combines the received information with the second information B stored in the storage unit 24a to create collation information. Here, in the present embodiment, for example, as shown in FIG. 7, position information is added to the first information A and the second information B. Therefore, by arranging the received information and the second information B on the bitmap based on the position information added to the received information and the position information added to the second information B, the received information It is possible to easily create collation information in which the second information B and the second information B are combined. Various methods can be used to combine the received information and the second information B. Then, the processing means 20a collates the reference information with the information indicating the characteristics of the created collation information. In this embodiment, the total number of bit data which is "1" in each row or each column or each row and each column of the collation information is equal to each row or the original information AB "a" stored as the reference information in the storage means 24a. Each column or each row is compared with the total number of bit data which is "1" in each column. The processing unit 20a confirms that the person is the individual when the information indicating the characteristics of the matching information matches the reference information stored in the storage unit 20a. For example, the use permission signal is output to the debit card 40a.

Next, another example of the first embodiment of the personal identification method is shown in FIG. In the present embodiment, for example, as shown in FIG. 8, the original information AB “A” is divided by a dividing line indicated by a one-dot chain line to obtain first information A and second information B. And the first
The information A is stored in the storage means 11a of the user portable device 10a, and the reference information indicating the characteristics of the second information B and the original information AB is stored in the storage means 24a of the user device 20a. In addition, when the position information is added to the first information A and the second information B, the storage means 11a and 24a are stored in, for example, FIG.
The first information A1 and the second information B1 are stored in the format shown in FIG. In the present embodiment, as the reference information indicating the characteristic of the original information AB "A", bit data of "1" in each row or each column or each row and each column of the bitmap information of the original information AB "A" is continuous. The number (run length) is used. In the case of the original information AB “A” shown in FIG. 8, each row (bit line) of the bitmap information of the original information AB “A”
The number of consecutive bit data of "1" in "1", that is, the first row (y = 1) is "1", the second row (y = 2) is "1,3", and the third row (y = 3). ) Is “7”, 4th line (y =
4) is "1", the fifth line (y = 5) is "1,1", the sixth line (y = 6) is "6", and the seventh line (y = 7) is "2,1,"
2 ”, ..., Reference information in which the 16th line (y = 16) is“ 0 ”is stored. Or, the original information AB "A"
Of the bit data of "1" in each column (bit line) of the bitmap information of, that is, 1
Row (x = 1) “0”, Row 2 (x = 2) “0”, Row 3 (x = 3) “3”, Row 4 (x = 4) “1, 2,
1 ", 5th column (x = 5)" 1,1,1 ", 6th column (x =
6) “1,1,1”, ..., 16th column (x = 1
6) "0" stores the reference information. Alternatively, the number of consecutive bit data of “1” in each column and each row (bit line) of the bitmap information of the original information AB “A” may be stored as the reference information. The bit line of the bitmap information of this embodiment corresponds to the "predetermined line" of the present invention.

In the case of this embodiment, when the processing means 23a of the user device 20a receives the information by the communication means 21a, the received information and the second information B stored in the storage means 24a.
Are combined to create verification information. And the processing means 2
0a collates the information indicating the characteristics of the created collation information with the reference information. For example, the number of consecutive bit data that is "1" in each row or each column or each row and each column is equal to each row or each column or each row of the original information AB "a" stored as reference information in the storage means 24a. The number of consecutive bit data of "1" in each column is collated. The processing unit 20a confirms that the person is the individual when the information indicating the characteristics of the matching information matches the reference information stored in the storage unit 20a.

In the above, the column or row of the bitmap information of the original information or the collation information is set to the bit line.
Bit lines are not limited to columns or rows of bitmap information. For example, a diagonal line of bitmap information can be set as a bit line. FIG. 9 shows an embodiment in which a diagonal line of bitmap information is set as a bit line. In FIG. 9, a line inclined downward to the right shown by a broken line or a line inclined upward to the right shown by a dashed line is set. In this case, the storage means 24a of the user device 20a stores in the bit map information of the original information AB a predetermined line in a line inclined downward to the right, a line inclined upward to the right, a line inclined downward to the right, and a line inclined upward to the right. Of information (for example, bit data that is "1") or the number of consecutive predetermined information is stored. Then, the processing means 24a outputs the total number of the predetermined information or the predetermined information in the line inclined downward to the right, the line inclined upward to the right, the line inclined downward to the right, and the line inclined upward to the right of the matching information. The identification is performed by determining whether or not the number of steps to be performed matches the reference information. Further, the shape, position, number, etc. of the bit lines can be changed as appropriate.

Although the bit data of "1" is collated, the bit data of "0" is collated or "1" is collated.
It is also possible to collate the bit data that is “0” and the bit data that is “0” (both binary data). Further, the present invention can be applied even when the data has three or more values. For example, in the case of color image information, the total number or continuous number of data of a specific color in the bit line of the matching information is compared with the reference information. Further, the method of forming the first information A and the second information B can be variously changed. For example, the first information A and the second information B may partially overlap. Further, it is not necessary to divide all of the original information AB into the first information A and the second information B (because the information obtained by combining the first information A and the second information B does not completely match the original information AB). Good). In this case, a method of extracting information indicating the characteristics of the reference information and the matching information is considered. Further, when collating the collation information with the information indicating the characteristics of the reference information, the collation is performed not only when the two completely match, but also when the ratio of both pieces of information is equal to or more than a predetermined value. It may be determined that the usage information and the reference information match. Further, the method of setting the reference information can be variously changed.

As described above, in the first embodiment, one piece of original information AB is divided into the first information (first divided information) A and the second information (second divided information) B, and the first information is divided. A is stored in the user portable device (first device), and the reference information indicating the characteristics of the second information B and the original information AB is stored in the user device (second device). Then, the user device receives the normal first information A when the information indicating the characteristics of the matching information created by combining the received information and the stored second information B matches the reference information. Make sure you are who you are. Therefore, the cost can be reduced compared to the case where the biometric information is used. Further, even if the personal identification number or the card is lost or stolen, there is no fear of illegal use unless the user portable device is lost or stolen. That is, since the first information obtained by dividing the original information is stored in the user portable device (first device), even if the user portable device (first device) is lost or stolen, the second information or the original information is lost. Information cannot be determined. Further, since the second information and the reference information obtained by dividing the original information are stored in the user device (second device), even if the user device (second device) is lost or stolen, the first information and Unable to determine the original information.

Next, FIG. 10 shows a block diagram of a second embodiment of the personal identification device of the present invention. In the second embodiment, the original information AB is divided into first information (first division information).

Then, after that, the signal received via the communication means 21a is demodulated and output to the processing means 23a. The storage means 24a stores the original information AB. The processing means 23a receives the information and dividing line information received by the communication means 21a and the original information AB stored in the storage means 24a.
Based on, it is confirmed whether or not the information received by the communication means 21a is the authentic first information A, that is, whether or not the person is the person.

Next, a procedure (a second embodiment of the personal identification method) for performing the personal identification processing using the above-mentioned second embodiment of the personal identification device will be described. FIG. 11 is a diagram illustrating an example of the processing procedure of the second embodiment of the personal identification method.

(v) When the user device 20a receives the information a and the dividing line information, the user device 20a confirms whether or not the user device 20a is the person based on the received information a and the dividing line information and the original information AB stored in the user device 20a.

Next, FIG. 13 shows an example of the second embodiment of the personal identification method. In this embodiment, the image information “A” is used as the original information AB. The original information AB “a” is converted into bitmap information, for example, as shown in FIG. The bitmap information is, for example, position data (x coordinate, y coordinate) having x (column) coordinates and y (row) coordinates.
And bit data at each position of the image information (for example, "black"
If it is white, it contains binary data of "1", and if it is white, it contains binary data). Then, the dividing line information indicating the position of the dividing line and the first information A is stored in the storage unit 11a of the user portable device 10a, and the original information AB is stored in the storage unit 24 of the user device 20a.

The bit length information (next one digit) and the bit data of the first row of the first information A (next eight digits) are shown. That is, the data “010180” in the first line (y = 1) of the first information A1 shown in FIG.
“0000010” is the x coordinate (first two digits) and y coordinate (next two digits) of the first bit data of the first line (y = 1) of the first information A (position of the first line of the dividing line) , The bit data length of the first row of the first information A (next digit) and the bit data of the first row of the first information A (next eight digits) are shown. As a result, the data “01018000000010” on the first line of the first information A1 shown in FIG.
The data of the line (that is, the position of the dividing line) is the position of (x coordinate, y coordinate) = (06,01), the bit data length is 3 digits, and each bit data is “110” in order.
It means that. The bit data length of the first information A may be omitted. However, if the bit data length of the first information A is added, the user device 20a
The process of extracting the information of each column of the first information A from the information received by is facilitated. Also, on the user device 20a side,
When the position of the first information A in the original information AB is predetermined, the transmission of the dividing line information from the user mobile device 10a may be omitted.

When the communication unit 21a receives the information and the dividing line information, the processing unit 23a of a receives the original information AB based on the received information and the dividing line information and the original information AB stored in the storage unit 24a. Check whether it matches a part of. Here, in this embodiment, the dividing line information is transmitted from the user portable device 10a to the user device 20a. Therefore, for example, as shown in FIG. 15, the original information AB is divided by the dividing line indicated by the dividing line information to obtain the first information A. Then, the obtained first information A is collated with the received information. Alternatively, the received information is superimposed on the position of the dividing line indicated by the dividing line information of the original information AB, and the received information is collated with a part of the original information A divided by the dividing line. In this way, by using the dividing line information, the process of matching the received information with a part of the original information becomes easy. And the processing means 20
When the received information matches a part of the original information AB, the a confirms that he / she is the person. For example, the use permission signal is output to the debit card 40a.

Next, another example of the second embodiment of the identity verification method of the present invention will be described. In the present embodiment, for example, as shown in FIG. 16, the original information AB “A” is divided by the dividing line indicated by the alternate long and short dash line to obtain the first information A. Then, the first information A and the dividing line information are stored in the storage means 11 of the user portable device 10a.
a and store the original information AB and the dividing line information in the user device 2
0a of the storage means 24a. User device 20a
In the storage means 24a of, for example, as shown in FIG.
Original information AB1 in which position information is added to bit data of original information AB and dividing line information indicating the position of the dividing line are stored. In FIG. 16, the coordinates of the first line of the dividing line are (05,0
1) The coordinates on the second line are (07, 02), ..., 8
It is shown that the coordinates of the line are (08,08). Further, in the storage means 11a of the user portable device 10a, for example, as shown in FIG. 17, first bit information of the first information A is added with bit length information of the first information A and dividing line dividing line information. Information A1 is stored. For example, in FIG.

The bit data length of the line is 4 digits, and 1 of the first information A
It indicates that the bit data of the row is “1110” in order. The bit data length may be omitted.

The user portable device 10a transmits the first information A and the dividing line information (first information A1) stored in the storage means 11a by the method described above. User device 20
When the communication unit 21a receives the information and the dividing line information, the processing unit 23a of a receives the dividing line information and the storage unit 2
The division line information stored in 4a is collated, and the received information is collated with part of the original information AB stored in the storage means 24a. First, based on the received information and dividing line information and the original information AB stored in the storage means 24a, it is confirmed whether or not the received information matches a part of the original information AB. For example, using the method described above, it is confirmed whether or not the received information and a part of the original information AB match. If the received information and part of the original information AB do not match, it is confirmed that the person is not the person (not the authorized user). When the received information matches a part of the original information AB, it is confirmed whether the received dividing line information matches the dividing line information stored in the storage means 24a. If the received dividing line information does not match the dividing line information stored in the storage means 24a, it is confirmed that the person is not the person.
When the received dividing line information matches the dividing line information stored in the storage means 24a, it is confirmed that the user is the original person (a legitimate user). The order of collating the received information with a part of the original information AB stored in the storage means 24a and the collation of the received dividing line information with the dividing line information stored in the storing means 24a are reverse. But it's okay. In this embodiment, since the received information is collated and the dividing line information is collated, the identification accuracy is improved.

In the above, the received information and a part of the original information are collated based on the dividing line information, but the method of collating the received information and a part of the original information uses the dividing line information. The method is not limited. Further, when collating the received information with a part of the original information, or collating the received dividing line information with the stored dividing line information, not only when the two completely match, Even when the rate at which both pieces of information match is greater than or equal to a predetermined value, it may be determined that both pieces of information match. Further, the received information and a part of the original information, or the received dividing line information and the stored dividing line information are collated for each row, but the collating method of the two information is not limited to this and various methods are possible. Any method can be used. The position of the dividing line can be set appropriately. Also,
The dividing line information may be stored on the user device 20a side.

As described above, in the second embodiment, one piece of original information AB is divided by the dividing line to obtain the first information (first dividing information) A, and the first information A and the dividing line information are combined. The user portable device (first device) stores the original information AB in the user device (second device). Then, the user device, based on the received information and the dividing line information, and the stored original information AB, when the received information matches a part of the original information AB, that is, the regular first information A is received. Make sure you are who you are. Therefore, the cost can be reduced compared to the case where the biometric information is used. Further, even if the personal identification number or the card is lost or stolen, there is no fear of illegal use unless the user portable device is lost or stolen. That is, since the user portable device (first device) stores the first information obtained by dividing the original information and the dividing line information, the user portable device (first device) is stored.
Even if the device is lost or stolen, the original information cannot be determined. Moreover, since only the original information is stored in the user device (second device), the first information cannot be determined even if the user device (second device) is lost or stolen. Further, by storing the dividing line information also in the user device (second device), the reliability is further improved.

Although the personal identification device using a debit card has been described above, the present invention can be used for various purposes. FIG. 18 shows a usage example when the mobile phone 40c is used as a user device. In the example illustrated in FIG. 18, the mobile phone 40b performs the identity verification process and determines whether to permit communication based on the result.
For example, the user device 20b provided in the mobile phone 40b is the information transmitted from the user mobile device 10b.
Only when (1) is the correct information corresponding to the information (2) stored by itself, the use of the mobile phone 40b is permitted. As a result, it is possible to prevent unauthorized use of the mobile phone 40b. Note that the user device is, in addition to the mobile phone, various user devices having a communication function, for example, a PH.
