The transmission interface 1H is provided for this purpose.

On the other hand, the key box 10 is a CPU 10 as a control means which is connected to the fingerprint reader 10A, the numeric keypad 10B and the display 10C described above via a bus.
R, which stores D, a processing program, fixed data, and the like
A key that is provided with an OM 10E, a RAM 10F that temporarily stores processed data, input data, and the like, and that unlocks the locked state of the lock mechanism of the key storage unit 10D that is a control target based on fingerprint collation so that the key can be taken out. A transmission interface 10H for transmitting data between the storage unit controller 1G and the fingerprint collation device 1 is provided.

Here, all the persons who pass through the building are designed to register their fingerprints with the fingerprint collation device 1, and the registration data of the person who uses the key box 10 is obtained from the fingerprint collation device 1 through the key box. It is supposed to be downloaded to 10.

The operation of the ID discriminating system having the above configuration will be described below with reference to the flow charts shown in FIGS. 5 to 7 are flowcharts which are stored in the ROM 1E of the fingerprint collation apparatus 1 and are executed under the control of the CPU 1D. First, in the flow chart 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 FIG.
The process moves to the flowchart shown in.

In the flow chart shown in FIG. 6, a predetermined I consisting of a personal identification number and a key box number is used.
By entering the D number from the numeric keypad (step S3)
(A person who does not use the key box uses only the personal identification number as the ID number), the fingerprint is read, and the characteristic points are calculated (steps S4 and S5). It is determined whether or not the calculated feature point data has a predetermined value "A" or more (step S6). If it is determined that the feature value data has a predetermined value "A" or more, the feature point data and the ID number are paired to the RAM. To store (step S
7). At this time, the fingerprint registration "OK" is displayed on the display.
At the same time as the display, the characteristic point data and ID number of the person having the storage part number of the key box are transmitted to the key box side and stored in the RAM to be downloaded (steps S8 and S9).

On the other hand, if it is determined in step S6 that the calculated feature point data is not more than the predetermined value "A", that is, if the fingerprint is difficult to read, then
It is determined whether or not there is a predetermined value "B" or more (step S1
0) If it is determined that the value is equal to or more than the predetermined value “B”, the feature point data and the “fingerprint small code” indicating that the read feature point data are few and the ID number are stored in the RAM (step S11). . Further, at this time, "OK" display of fingerprint registration is displayed on the display unit, and the feature point data and ID number of the person having the storage unit number of the key box are transmitted to the key box and stored in the RAM. It is downloaded (steps S8 and S9).

If it is determined in the above step S10 that the calculated feature point data is not more than the predetermined value "B", that is, if the fingerprint is more difficult to read, it is determined that there is no fingerprint whose matching level is zero during fingerprint matching. Well, the "fingerprint-free code" and the ID number indicating this are RA
It is stored in M (step S12). Also, at this time,
Fingerprint registration "OK" is displayed on the display,
The "fingerprint-free code" and the ID number are transmitted to the key box and stored in the RAM to be downloaded (steps S8 and S9).

Returning to the flow chart shown in FIG. 5, when there is no fingerprint registration mode setting input in step S1 and there is a fingerprint collation mode setting input from the numeric keypad (step S13), the "fingerprint" is displayed on the display. The "verification mode" is displayed (step S14). In this state, when the ten key is input and the personal identification number is input, the input personal identification number is collated (step S16). If the result is NG, "NG" is displayed on the display (step S17), the process returns to step S15, and OK.
In case of, the fingerprint is read by displaying "Please place your finger" on the display (step S1).
8). After that, the fingerprint is read, the characteristic point data of the fingerprint is calculated, and it is determined whether or not the characteristic point data in the RAM corresponding to the personal identification number matches within a predetermined range (step S
19-S21).

The operation after the comparison of the characteristic point data is shown in FIG.
The process moves to the flowchart shown in. That is, the feature point data calculated by reading the fingerprint and the RA corresponding to the personal identification number
If the result of comparison with the feature point data in M indicates that they match, “OK” is displayed on the display and the electric lock on the door is temporarily unlocked (step (S22, S23), a person can turn the knob to enter the building, and the entrance door is closed after entering (step S24, S23).
S25).

On the other hand, as a result of comparison between the characteristic point data calculated by reading the fingerprint and the characteristic point data in the RAM corresponding to the personal identification number, if it is determined that they do not match, it corresponds to the input personal identification number. It is determined whether or not the "fingerprint small code" is stored in the data stored in the RAM (step S26), and if the person is not the "fingerprint small code", "NG" is displayed on the display (step S26). S27), if the person has a "fingerprint small code", it is determined whether the feature point data of the fingerprints 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, and it is determined whether the feature point data in the RAM corresponding to the personal identification number matches within a predetermined range. The fingerprint collation accuracy can be changed by changing the collation level to the data level.

Next, FIG. 8 and FIG. 9 show R of the key box 10.
6 is a flowchart stored in the OM 10E and executed under the control of the CPU 10D. First,
In the flowchart shown in FIG. 8, the "fingerprint matching mode" is displayed on the display (step S31). In this state, when the numeric keypad is input and the personal identification number is input, the input personal identification number is verified (step S
32, S33). As a result, in the case of NG, "N
"G" is displayed (step S34), so that step S
Returning to step 32, in the case of OK, "Please place your finger" is displayed on the display unit to read the fingerprint (step S35). After that, the fingerprint is read, the characteristic point data of the fingerprint is calculated, and it is determined whether or not the characteristic point data in the RAM corresponding to the personal identification number match within a predetermined range (steps S36 to S38).

The operation after the comparison of the characteristic point data is shown in FIG.
The process moves to the flowchart shown in. That is, the feature point data calculated by reading the fingerprint and the RA corresponding to the personal identification number
If the result of comparison with the feature point data in M indicates that they match, “OK” is displayed on the display and the lid of the corresponding key storage section is unlocked. (Steps S39 and S40) The key can be taken out or stored, and the lid is automatically locked again by closing the lid after taking out or storing the key (Step S4).
1, S42).

On the other hand, as a result of comparison between the feature point data calculated by reading the fingerprint and the feature point data in the RAM corresponding to the personal identification number, if it is determined that they do not match, it corresponds to the input personal identification number. It is determined whether or not the "fingerprint small code" is stored in the data stored in the RAM (step S43), and if the person is not the "fingerprint small code",
It is determined whether or not the person has a "fingerprint-free code" (step S4).
4) If the person is a "fingerprint-free code", repeat step 40 below. If the person does not have the "no fingerprint code", "NG" is displayed on the display (step S4).
5). If the person has a "fingerprint low code", it is determined whether the feature point data of the fingerprints match within a predetermined collation level (step S46). If the result of the determination is that they do not match, "NG" is displayed on the display (step S4).
5) If there is a match, step S40 and subsequent steps are repeated.
In this way, the fingerprint is read, the feature point data of the fingerprint is calculated, and it is determined whether the feature point data in the RAM corresponding to the personal identification number matches within a predetermined range. The fingerprint collation accuracy can be changed by changing the collation level to the data level.
