FIG. 3 is a sequence for explaining processing in each configuration of the paper sheet processing system shown in FIG.
In such a configuration, the counting information auditing process will be described with reference to the flowchart shown in FIG.

  First, banknotes are inspected in the inspection machine main body 30, and a counting process is performed (S11). That is, the inspection machine main body 30 performs authenticity determination while transporting banknotes one by one, and further determines whether the genuine note is correct or not, thereby classifying it into a correct note and a damaged note. Every time it is sealed, it is cut so that it cannot be reused. The main control unit 21 of the inspection machine main body 30 acquires the accumulated money amount information of the cut banknotes from at least the type and number of banknotes determined to be non-payables among the correct and non-performing bills (step S12). In addition, you may make it acquire the total amount information of both the correct ticket and the non-performing ticket which performed the counting process.

  The main control unit 21 generates a MAC using an encryption key and monetary information stored in a storage unit (not shown) in the control unit 11, and the date, time, count value, and the like (step S13). The main control unit 21 transmits the money amount information, date, time, count value, etc., and the MAC to the PC 12 (step S14).

  The PC 12 stores the money amount information, date, time, count value, and the like transmitted from the main control unit 21 and the MAC in the storage unit in the PC 12 (step S15). At the same time, the PC 12 transmits the amount information, date, time, count value, etc., and the MAC to the customer server 1 shown in FIG. 1 (step S16).

  The customer server 1 stores the money amount information transmitted from the PC 12, the date, time, count value, etc., and the MAC in the storage unit in the customer server 1 (step S17).

  Here, when the IC card C is inserted into the IC reader / writer of the PC 12 and an operation for displaying the inspection result is input, the PC 12 displays the monetary amount information, date, time, count value, etc., and the MAC as the IC card C. (Step S18).

  The IC card C generates a MAC from the amount information transmitted from the PC 12, the date, time, count value, etc., and the encryption key stored in the ROM of the IC card C (step S19). The IC card C performs an authentication process as to whether or not the generated MAC matches the MAC transmitted from the PC 12 (step S20). The IC card C transmits the authentication result as a response to the PC 12 (step S21).

  The PC 12 displays the received authentication result on the display unit of the PC 12 (step S22). Further, between the customer server 1 and the IC card C, as shown in steps S23 to S27, the same processing as the above-described steps S18 to S22 is performed.

  In this authentication process, when it is determined that the MAC received from the PC 12 matches the generated MAC, the IC card C determines that the data received from the PC 12 has not been tampered with. If it is determined that the MAC received from the PC 12 and the generated MAC do not match, the IC card C determines that the data received from the PC 12 has been tampered with.

  In addition to the authentication result, the result of the counting process, for example, the total amount information of the cut bills may be displayed. Further, whether or not to display the result of the counting process may be determined and displayed according to the received authentication result. According to the paper sheet processing system configured as described above, the inspection machine main body 30 divides the banknotes into types such as a correct ticket, a damaged ticket, and an excluded ticket, counts each, and at least the banknote of the damaged ticket. Information on the accumulated amount of non-performing tickets is obtained from the type and number of sheets. The inspection machine body 30 generates a MAC from the acquired amount information, a random number such as a counter value, date or time, and a stored encryption key, and stores the amount information, the above random number, and the generated MAC. Are transmitted to the PC 12. The PC 12 stores the received data and transmits it to the customer server 1 at the same time. The customer server stores the received data.

  Here, when the IC card C is inserted into the IC reader / writer of the PC 12 and an operation for confirming whether the accumulated money amount information of the non-performing ticket stored in the PC 12 and the MAC is correct is input, the PC 12 The MAC and the random number described above are transmitted to the IC card C. The IC card generates a MAC based on the received data, performs an authentication process as to whether or not it matches the received MAC, and transmits an authentication result to the PC 12. The PC 12 displays the received authentication result.

  As described above, the MAC is not generated for each ticket type, but the MAC is generated based on the accumulated money amount information, so that it is possible to prevent tampering with the count information of the damaged ticket by a simple process. With the above configuration, it is possible to provide a paper sheet processing apparatus, a paper sheet processing method, and an authentication system that can process paper sheets more quickly.
