  As a technique for preventing unauthorized use of an IC card, there is a technique for authenticating the match / mismatch between an IC card user and an IC card holder based on biometric information (see, for example, Patent Documents 1 and 2).

  In the technique of Patent Document 1, the fingerprint data of the person is recorded in advance on the card, and the fingerprint of the person who brought the card is read by the fingerprint reading means. The fingerprint data read by the fingerprint reading means and the fingerprint data recorded on the card are collated to determine whether or not the user is the person himself / herself.

  Therefore, the technique of Patent Document 1 can be easily managed and quickly verified as to whether or not the person is the person.

  In the technique of Patent Document 2, the registered biometric authentication information is divided and stored in the IC card or the center device, the biometric authentication information acquired from the user at the time of authentication is also divided, and the divided information is collated.

  Therefore, the technique of Patent Document 2 does not need to reproduce the divided information and can improve the safety of the biometric authentication information. Moreover, since a random number, a personal identification number obtained from a user, or the like is used as a rule for division, it is difficult for a third party to guess the division rule, and the entire information is estimated from a part of the divided information. Can reduce the risk.

  The spectrum waveform conversion unit 231 extracts a plurality of spectrum waveforms 510 decomposed into fingerprint partial information 115 from the fingerprint image 50 read by the first biological information reader 21. Note that the spectrum waveform conversion unit 231 may include means for performing frequency conversion such as Fourier transform on the grayscale waveform to obtain a frequency spectrum, and may extract the frequency spectrum as a plurality of spectrum waveforms 510.

  The spectrum waveform comparison unit 232 compares the spectrum waveform 510 extracted by the spectrum waveform conversion unit 231 with the fingerprint portion information 115 read from the IC card 10.

  The authentication unit 233 determines whether the comparison results match / mismatch. When it is determined that they match, the authentication unit 233 gives authentication that the user of the vending machine 40 and the holder of the IC card 10 match.

  When the authentication unit 233 determines that there is a mismatch, the biometric authentication device 23 again uses the unused fingerprint portion information 115 (first spectrum waveform 116-1) in the inner spectrum waveform comparison unit 232 of the fingerprint portion information 115 read from the IC card 10. The spectrum waveform comparison unit 232 compares the spectrum waveform 510 extracted by the spectrum waveform conversion unit 231 with an unused one of the .about.nth spectrum waveform 116 -n.

  Referring to FIG. 9, the control unit 25 controls the card settlement apparatus 20 and also controls the merchandise sales apparatus 30, and performs a biometric authentication process control unit 250, a settlement process control unit 260, and a product takeout control unit 270. With.

  The biometric authentication process control unit 250 instructs display contents on the display 24 in the biometric authentication process, and includes a product name / price display instruction unit 251, a fingerprint reading display instruction unit 252, and an IC card reading display instruction unit 253.

  The selection button unit 31 includes a storage unit 312 that stores product name information 313 corresponding to each button and price information 314 of the product name. The selection button unit 31 outputs the product name information 313 and the price information 314 of the product name when the user selects a product desired to be purchased and presses the button, and transmits it to the control unit 25.

  The product take-out device 32 includes a product storage unit (not shown) for storing a plurality of products, and in response to a discharge instruction based on the product name information 313 from the control unit 25, takes out the product of the product name information 313 from the outlet of the vending machine 40. It is discharged (not shown).

  Next, the operation of the card payment system 80 configured as described above will be described with reference to the drawings.

  FIGS. 12 and 13 are flowcharts for explaining the operation of the card payment system 80.

  Referring to FIGS. 12 and 13, the user selects a product desired to be purchased in front of the vending machine 40 and presses a button on the product sales apparatus 30 (S101).

  The selection button unit 31 of the product sales device 30 transmits the product name information 313 and the price information 314 corresponding to the pressed button to the control unit 25 of the card settlement device 20 (S102).

  When receiving the product name information 313 and the price information 314, the control unit 25 starts a biometric authentication process for the user (S103).

  The control unit 25 instructs the display 24 to display the product name and the price using the product name / price display instructing unit 251, and the fingerprint reading display instructing unit 252 instructs the display unit 24 to display the user's fingerprint. Is displayed on the first biological information reader 21 (S104).

  The display 24 displays the product name and the price, and displays prompting the fingerprint to be read into the first biological information reader 21 (S105).

  The first biometric information reader 21 reads the fingerprint of the user and transmits a fingerprint image 50 as the first biometric information to the biometric authentication device 23 (S106).

  The biometric authentication device 23 converts the fingerprint image 50 into a 100-line spectrum waveform 510 (spectrum waveforms 510-1 to 510-100) by the spectrum waveform conversion unit 231 and extracts it as fingerprint partial information 115 (S <b> 107).

  The biometric authentication device 23 transmits the extraction end information of the fingerprint portion information 115 to the control unit 25 (S108).

  The control unit 25 instructs the display 24 to display a message prompting the user to read the IC card 10 into the reader / writer 22 by the IC card reading display instruction unit 253 (S109).

  The display 24 displays that the IC card 10 is read into the reader / writer 22 (S110).

  The user holds the IC card 10 over the reader / writer 22 (S111).

  The reader / writer 22 communicates with the first communication unit 120 of the IC card 10 through the second communication unit 223, and reads the management information 130 stored in the IC card 10 (S112). The management information 130 is an identification number 111 of the IC card 10 consisting of alphanumeric characters, holding amount information 112, and second biological information 113 of the holder of the IC card 10. Among these, the second biological information 113 is stored as fingerprint partial information 115 (first spectrum waveform 116-1 to n-th spectrum waveform 116-n) (provided that 2 ≦ n ≦ 20). The reader / writer 22 uses the spectrum waveform number determination unit 222 to determine the number of fingerprint partial information 115 to be read (the number read from the first spectrum waveform 116-1 to the nth spectrum waveform 116-n).

  Here, the number to be read may be determined by comprehensively considering the accuracy of the biometric authentication process, the communication speed between the IC card 10 and the reader / writer 22, and the processing speed of the biometric authentication device 23.

  As the number of readouts increases, the amount of information for authenticating the match / mismatch increases as compared with the spectrum waveform 510 of the first biometric information, and the accuracy of biometric authentication increases. However, the amount of information transferred from the IC card 10 to the reader / writer 22 increases, and the transfer time increases. Further, the biometric authentication device 23 increases the amount of information to be authenticated and increases the processing time.

  Therefore, the number to be read is determined to be an optimum number so that the biometric authentication and the payment process are completed within the time when the user holds the IC card 10 over the reader / writer 22. For example, if the time for which the user holds the IC card 10 over the reader / writer 22 is 0.5 seconds, the biometric authentication process, the biometric authentication process in the case of mismatch, and the payment process are performed for 0.5 seconds. The number to be read is determined so that the process can be completed within a predetermined time.

  Here, as an example, it is assumed that the number of fingerprint portion information 115 to be read is one, and the reader / writer 22 reads the first spectrum waveform 116-1, and the operation will be described below.

  The reader / writer 22 transmits the read first spectrum waveform 116-1 to the biometric authentication device 23 (S113).

  The biometric authentication device 23 compares the first spectrum waveform 116-1 with the 100-line spectrum waveforms 510-1 to 510-100 extracted in the above (S107) by the spectrum waveform comparison unit 232 (S114).

  The authentication unit 233 determines whether or not the first spectrum waveform 116-1 matches any of the 100 spectrum waveforms 510-1 to 510-100 (S115, S116).

  When the number of fingerprint portion information 115 to be compared is plural (for example, three cases of first spectrum waveform 116-1, second spectrum waveform 116-2, and third spectrum waveform 116-3). If the number (two in this example) of more than half of the total matches one of the spectrum waveforms 510-1 to 510-100, the authentication unit 233 recognizes the user's fingerprint and the IC card 10. Judge that the fingerprint of the holder matches. The authentication unit 233 authenticates that the user of the vending machine 40 matches the owner of the IC card 10.

  When the biometric authentication device 23 determines a match in the match / mismatch determination (S116), the determination result is transmitted to the control unit 25, and the control unit 25 ends the biometric authentication process (S117) and performs the payment process. Start (S127).

  When the biometric authentication device 23 determines that there is a mismatch, the determination result is transmitted to the control unit 25, and the control unit 25 again causes the IC card reading / display instruction unit 253 to hold the IC card 10 to the user with the reader / writer 22. The display 24 is instructed to prompt the reading (S118).

  The display 24 displays that the IC card 10 is read into the reader / writer 22 (S119).

  The user again holds the IC card 10 over the reader / writer 22 (S120).

  The processes (S118) to (S120) are applied only to a case where the biometric authentication process cannot be performed again within the time when the user holds the IC card 10 over the reader / writer 22. Usually, the processing of (S118) to (S120) is not necessary.

  For example, the biometric authentication process, the biometric authentication process in the case of mismatching, and the payment process are set so that they can be completed in 0.5 seconds, and the time for the user to hold the IC card 10 over the reader / writer 22 is set. Assume that 0.5 seconds. However, when the time for the user to hold the IC card 10 is 0.1 seconds, the biometric authentication process shown below (S121) cannot be performed again while holding the IC card 10 once. is there.

  The reader / writer 22 communicates with the first communication unit 120 of the IC card 10 through the second communication unit 223. The reader / writer 22 selects, for example, from the unused fingerprint portion information 115 (second spectrum waveform 116-2 to n-th spectrum waveform 116-n) that has not been read in (S113) as the second biological information 113, for example, The second spectrum waveform 116-2 is read (S121).

  The reader / writer 22 transmits the read second spectrum waveform 116-2 to the biometric authentication device 23 (S122).

  The biometric authentication device 23 compares the second spectrum waveform 116-2 with the 100-line spectrum waveforms 510-1 to 510-100 extracted in (S107) by the spectrum waveform comparison unit 232 (S123).

  The authentication unit 233 determines whether or not the second spectrum waveform 116-2 matches any of the 100 spectrum waveforms 510-1 to 510-100 (S124, S125).

  When the biometric authentication device 23 determines that there is a mismatch (S125), the determination result is transmitted to the control unit 25, and the control unit 25 stops the settlement process of the IC card 10 (S126).

  In the above description, the biometric authentication process is performed twice as an example, but the possible number of executions of the biometric authentication process depends on the time when the user holds the IC card 10 over the reader / writer 22. Needless to say, the present invention also includes performing biometric authentication processing three or more times.

  When the biometric authentication device 23 determines that they match, the process returns to (S117).

  When the settlement process is started (S127), the control unit 25 instructs the reader / writer 22 to update the new holding amount information 112 by using the IC card holding amount information update instruction unit 261 (S128).

  The reader / writer 22 rewrites and changes the holding amount information 112 of the IC card 10 to the new holding amount information 112 using the information obtained by subtracting the price information 314 from the current holding amount information 112 as the new holding amount information 112 (S129). .

  The control unit 25 confirms the completion of the settlement process by the IC card 10 (S130), and instructs the display unit 24 to display the completion of the price settlement process for the product by the settlement process end display instruction unit 262. (S131).

  The display 24 displays that the payment processing has been completed (S132).

  The control unit 25 instructs the product take-out device 32 of the product sales device 30 to discharge the product corresponding to the product name information 313 (S133).

  The product take-out device 32 discharges the product corresponding to the product name information 313 to the take-out port (S134).

  The card payment system 80 described above uses the partial information of the first biometric information and a part of the partial information of the second biometric information 113 for biometric authentication. Therefore, the card payment system 80 has a small amount of information for biometric authentication processing, can shorten the authentication processing time, and can perform biometric authentication and payment processing while the user holds the IC card 10 over the reader / writer 22. There is.

  Further, the card payment system 80 uses the second biometric information 113 of the authorized holder of the IC card 10 stored in the IC card 10 to authenticate the user. There is an effect that it can be prevented.
