The fingerprint collation accuracy of the fingerprint collation apparatus 1 installed in a place with low security is set lower than the fingerprint collation accuracy of the key box 10 installed in a place with high security.
[0018]
The operation of the ID discrimination system according to the above configuration will be described below with reference to the flowcharts shown in FIGS.
5 to 7 show flowcharts that are stored in the ROM 10E of the key box 10 and executed under the control of the CPU 10D.
First, in the flowchart shown in FIG. 5, when the fingerprint registration mode is set from the numeric keypad (step S1), the “fingerprint registration mode” is displayed on the display (step S2), and the flowchart shown in FIG. Migrate to
[0019]
In the flowchart shown in FIG. 6, by inputting a predetermined ID number consisting of a personal identification number and a key storage unit number from the numeric keypad (step S3), the fingerprint is read and feature points are calculated (steps S4 and S5). . It is determined whether or not the calculated feature point data is greater than or equal to the predetermined value “A” (step S6). If it is determined that the calculated feature point data is greater than or equal to the predetermined value “A”, the feature point data and the ID number are paired into the RAM. (Step S7). At this time, “OK” is displayed on the display for fingerprint registration, and only the identification number of the ID number and the feature point data are also transmitted to the fingerprint verification device and stored in the RAM. (Steps S8 and S9).
[0020]
On the other hand, if it is determined in step S6 that the calculated feature point data is not greater than or equal to the predetermined value “A”, that is, if the fingerprint is difficult to read, then it is determined whether or not it is greater than or equal to the predetermined value “B”. If it is determined (step S10) and it is determined that the value is equal to or greater than the predetermined value “B”, the feature point data and the “fingerprint small code” indicating that the feature point data read is small and the ID number are stored in the RAM. (Step S11). At this time, “OK” is displayed on the display for fingerprint registration, and only the ID number of the ID number, the feature point data, and the “fingerprint small code” are transmitted to the fingerprint collation device and stored in the RAM. (Steps S8 and S9).
[0021]
If it is determined in step S10 that the calculated feature point data is not greater than or equal to the predetermined value “B”, that is, if the fingerprint is more difficult to read, there may be no fingerprint with a matching level of zero during fingerprint matching. The "no fingerprint code" indicating this and the ID number are stored in the RAM (step S12). At this time, “OK” is displayed on the display for fingerprint registration, and only the ID number of the ID number and “no fingerprint code” are transmitted to the fingerprint verification device and stored in the RAM. (Steps S8 and S9).
[0022]
Returning to the flowchart shown in FIG. 5, if there is no setting input for the fingerprint registration mode in step S1 and there is a setting input for the fingerprint verification mode from the numeric keypad (step S13), the “fingerprint verification mode” is displayed on the display. Is displayed (step S14). In this state, when a numeric keypad is input and a personal identification number is input, the input personal identification number is collated (step S16). As a result, in the case of NG, “NG” is displayed on the display (step S17), and the process returns to step S15. In the case of OK, “Please place your finger” is displayed on the display. Is read (step S18).
Thereafter, the fingerprint is read, the feature point data of the fingerprint is calculated, and it is determined whether or not the feature point data in the RAM corresponding to the password is matched within a predetermined range (steps S19 to S21).
[0023]
The operation after the feature point data comparison is shifted to the flowchart shown in FIG. That is, when it is determined that the feature point data calculated by reading the fingerprint and the feature point data in the RAM corresponding to the personal identification number match, “OK” is displayed on the display. At the same time, when the lid of the corresponding key storage unit is unlocked (steps S22 and S23), the key can be taken out or stored, and the lid is auto-locked again by closing the lid after taking out or storing. (Steps S24 and S25).
[0024]
On the other hand, if the comparison result between the feature point data obtained by reading the fingerprint and the feature point data in the RAM corresponding to the personal identification number is determined to be inconsistent, it is stored in the RAM corresponding to the input personal identification number. It is determined whether or not the “fingerprint small code” is stored in the stored data (step S26). If the person does not have the “fingerprint small code”, “NG” is displayed on the display (step S27). If it is a person with a “fingerprint small code”, it is determined whether or not the fingerprint feature point data match within a predetermined collation level (step S28). If the result of the determination is that they do not match, “NG” is displayed on the display (step S27), and if they match, step S23 and subsequent steps are repeated.
In this way, the fingerprint is read, the feature point data of the fingerprint is calculated, it is determined whether or not the feature point data in the RAM corresponding to the PIN number matches within a predetermined range, and the same feature point as at the time of registration The fingerprint verification accuracy can be changed by changing the verification level to the data level.
[0025]
Next, FIGS. 8 to 10 are flowcharts that are stored in the ROM 1E of the fingerprint collation apparatus 1 and executed under the control of the CPU 1D.

[0026]
In the flowchart shown in FIG. 9, by inputting a predetermined password from the numeric keypad (step S33), the fingerprint is read and the feature points are calculated (steps S34 and S35). It is determined whether or not the calculated feature point data is greater than or equal to a predetermined value “A” (step S36). If it is determined that the calculated feature point data is greater than or equal to the predetermined value “A”, the feature point data and the password are paired into RAM. (Step S37). At this time, “OK” is displayed on the display for fingerprint registration (step S38).
[0027]
On the other hand, if it is determined in step S36 that the calculated feature point data is not greater than or equal to the predetermined value “A”, that is, if the fingerprint is difficult to read, then it is determined whether or not it is greater than or equal to the predetermined value “B”. If it is determined (step S39) and it is determined that the value is equal to or greater than the predetermined value “B”, the feature point data and the small fingerprint code and the code number indicating that the feature point data read are small are stored in the RAM (step S39). S40). At this time, “OK” is displayed on the display for fingerprint registration (step S38).
[0028]
If it is determined in step S39 that the calculated feature point data is not greater than or equal to the predetermined value “B”, that is, if the fingerprint is more difficult to read, there may be no fingerprint at the time of fingerprint collation. The code and the password are stored in the RAM (step S41). At this time, “OK” is displayed on the display for fingerprint registration (step S38).
[0029]
Returning to the flowchart shown in FIG. 8, if there is no setting input for the fingerprint registration mode in step S31 and there is a setting input for the fingerprint verification mode from the numeric keypad (step S42), the “fingerprint verification mode” is displayed on the display. Is displayed (step S43). In this state, when there is a numeric keypad input and a password is input, the input password is verified (steps S44 and S45). As a result, in the case of NG, “NG” is displayed on the display (step S46), and the process returns to step S44. In the case of OK, “Please place your finger” is displayed on the display. Is read (step S47).
Thereafter, the fingerprint is read, the feature point data of the fingerprint is calculated, and it is determined whether or not the feature point data in the RAM corresponding to the password is matched within a predetermined range (steps S48 to S50).
[0030]
The operation after the feature point data comparison is shifted to the flowchart shown in FIG.
That is, when it is determined that the feature point data calculated by reading the fingerprint and the feature point data in the RAM corresponding to the personal identification number match, “OK” is displayed on the display. At the same time, by temporarily unlocking the electric lock of the doorway door (steps S51 and S52), a person can enter the hall by turning the knob, and after entering the doorway, the doorway door is closed (steps S53 and S54).
[0031]
On the other hand, if the comparison result between the feature point data obtained by reading the fingerprint and the feature point data in the RAM corresponding to the personal identification number is determined to be inconsistent, it is stored in the RAM corresponding to the input personal identification number. It is determined whether or not the “fingerprint small code” is stored in the stored data (step S55), and if it is not the “fingerprint small code” person, it is determined whether or not it is the “fingerprint no code” person ( In step S56), if the person is "no fingerprint code", step S51 is executed and step S52 and subsequent steps are repeated. If it is a person with “no fingerprint code”, it is determined whether or not the fingerprint feature point data match within a predetermined collation level (step S57). If the result of the determination is that they do not match, “NG” is displayed on the display (step S58). If they match, step S51 is executed and step S52 and subsequent steps are repeated.
In this way, the fingerprint is read, the feature point data of the fingerprint is calculated, it is determined whether or not the feature point data in the RAM corresponding to the PIN number matches within a predetermined range, and the same feature point as at the time of registration The fingerprint verification accuracy can be changed by changing the verification level to the data level.
