Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. The entrance / exit management device of the present invention is functionally broadly divided into an entrance / exit management device 1 and an exit / exit management device 2 and is connected via a database 3. The entrance management device 1 is connected to a card reader 11 for recognizing an entrance ticket, a gate control device 12 for opening / closing a gate of the venue, and a finger information collection / collation device 13.

The exit management device 2 includes a gate opening / closing control device 21 for performing gate opening / closing control, and a finger information collection / registration device 22.
Is connected. As described later, the finger information collection and collation device 1
3 and the finger information collection / registration device 22 can be shared and realized by one device module. FIG. 2 shows the internal configuration.

FIGS. 3 and 4 are flowcharts showing the operation of the embodiment of the present invention. For the former, the processing at the time of temporary exit,
The latter shows the process at the time of re-entry.

The operation of the embodiment of the present invention will be described below with reference to the flowcharts shown in FIGS. Normal entry is managed by the entry management device 1, and is entered and confirmed via the card reader 12 such as an entrance ticket. Here, if a correct card is input, the gate is opened by the gate opening / closing control device 11, and entry is permitted. At the time of temporary exit, fingerprint information input for finger authentication is performed by the finger information collection / registration device 22 of the exit management device 2, the finger information is registered in the database 3, and the gate opening / closing control device 21 is driven to open the gate. Becomes The details of the finger information collection and finger information registration (collation) operations will be described later.

At the time of re-entry, the finger information is input again by the finger information collection and collation device 13 of the entrance management device 1, and collation with the information registered in the database 3 is performed. As a result of the comparison and collation, if they match, a temporary exit person is re-entered, and the gate opening / closing control device 11 is driven to open the gate and permit entry.

FIG. 2 shows the internal configuration of the finger information collection / collation (registration) device. Finger information collection and collation (registration) device 13 (22)
Functionally comprises a finger information collecting unit and a finger information collating (registering) unit. First, the finger information collection unit will be described. In the figure, 31 is an electrode. The user places his / her finger in a vertical direction on the electrodes 31 arranged in an array as shown in the figure. 32 is a switch circuit. The switch circuit 32 is an analog switch controlled by the timing pulse generator 37. 33 is a power supply. Power supply 33
Generates a voltage to be supplied to a closed circuit formed between two adjacent electrodes when a finger is placed on an electrode and an arbitrary switch 32 is closed. 34 is a reference resistor. Due to the voltage drop at the resistor 34, two adjacent
The magnitude of the current flowing in a closed circuit composed of two electrodes is measured. 35 is a sampling hold circuit. The sampling and holding circuit 35 samples a potential difference between both ends of the reference resistor 34 at a given timing. 36 is an AD converter. The AD converter 36 converts the voltage obtained by the sampling and holding circuit 35 into a digital signal.

Reference numeral 37 denotes a timing pulse generator. The timing pulse generator 37 gives a switching timing of the switch 32, a sampling timing of the sampling and holding circuit 35, and a pointer switching timing of a memory circuit 38 described later. 38 is a memory circuit. The memory circuit 38 stores the data digitized by the AD converter 36. 39 is a parallel-to-serial conversion circuit. The parallel / serial conversion circuit 39 converts the parallel data into bit serial data, and transfers the data to a finger information database or a finger information matching (registering) unit for performing database registration via a serial transfer path (not shown).

The finger information collating (registering) section includes a serial / parallel conversion circuit 41, an operation mode switch 42, and a database memory 4.
3, the comparison and matching circuit 45, the data buffer 44, and
It is composed of a gate circuit 46. The serial / parallel conversion circuit 41 converts the serial bit signal from which the finger information has been collected and transmitted to parallel data, and stores it in the database memory 43 or the data buffer 44 via the switch 42. The finger information fetched into the data buffer 44 is compared and compared with the finger information registered in the database memory 43 by the comparison and matching circuit 45, and the comparison result controls the opening and closing of the gate 46. The switch 42 connects the output of the serial / parallel circuit 41 to the database memory 43 or the data buffer 44 according to the operation mode of registering the collected finger information in the database or performing comparison and collation.

The operation of finger information collection, finger information registration and collation in the above configuration will be described. As shown in the figure, when performing authentication, a user touches a finger on the electrodes 41 arranged in an array. At this time, as shown in the figure, the resistance between the electrodes (the resistance of the finger) is set to Ri (i =
1, 2,... N), the power supply is V0, the resistance is Rref, and the resistance R
When the voltage applied to both ends of ref is Vi, Vi is determined by the following equation (1).

Vi = V0 · Rref / Rref + Ri (1) When the contact area of the finger is large, Ri becomes small and therefore Vi becomes large. Conversely, when the contact area of the finger surface is small, Ri increases, and therefore Vi decreases. In this way, the fingerprint information is reflected on Vi as a result, so that the fingerprint information can be obtained from the Vi array information.

A timing pulse generator 37 switches the analog switch 32 and generates a control signal for the sampling and holding circuit 35. The analog switch 32 is switched at the falling edge of the timing pulse, and the sampling and holding circuit 35 samples at the rising edge. The data sampled by the sampling and holding circuit 35 is digitally converted by the AD converter 36. The digitally converted data is sequentially written to the memory 38.

There are two operations for collecting fingerprint information.
Database registration or finger verification. If the database registration mode has been set, the memory device 38
Is written to the data buffer 44 as it is via the parallel / serial conversion circuit 39, the serial / parallel conversion circuit 41, and the operation mode switch 42. Next, when the operation mode switch 42 is in the finger collation mode, the comparison / collation circuit 45 receives the fingerprint collection data written in the memory 38, and
3 is compared with a fingerprint database stored in advance. If the correlation is higher than a preset correlation threshold, a trigger signal is generated, and a control signal for opening the gate 46 is generated. If it is lower than the threshold, no trigger signal is generated. In this way, a trigger signal is generated only when it is determined that the person who has performed the finger verification matches the person registered on the database, and this trigger signal is a control signal for opening and closing the gate.

In the embodiment of the present invention, the circuit for collecting finger information and the circuit for registration and verification are shown separately. However, they can be incorporated in one module. Therefore, the direct (parallel) column conversion circuits 39 and 41 and the memory 38 are not required, and the comparison / collation circuit 45 can be replaced by a processor or the like.

FIG. 5 is a block diagram showing another embodiment of the present invention. In the embodiment shown in FIG. 5, a card output device 23 for issuing a card is added to the exit management device shown in FIG.
Further, the function for collating finger information is extended. Although details will be described later, for convenience, the finger information collection and collation (registration) device connected to the entrance management device 1 and the exit management device 2 is
The description will be continued with a finger information collection authentication collation (authentication registration) device 14 (24). The card output device 23 is for issuing a ticket by giving an index of finger information to a card when the player temporarily leaves the card, and loading the card into the card input device 12 and reading the index upon re-entry. Is used to collate finger information based on It is used to reduce the time required for finger authentication,
Furthermore, by allocating a storage area and writing partial information, it can be used for various services such as history management such as counting of the number of exits.

FIGS. 6 and 7 show the operation of the embodiment shown in FIG. 5 as a flowchart.

The operation of the embodiment shown in FIG. 5 will be described below in detail with reference to FIGS. First, entry is the same as in the embodiment shown in FIG. At the time of temporary withdrawal, finger information collection is performed by the finger information collection authentication information matching device 24 of the leave management device 2 and registration of the database 3 is performed. At this time, a ticket is issued by the card output device 23, a unique number is given to each issued card, and a card-specific number associated with the collected finger information is registered in the database 3 as an index.

At the time of re-entry, the card issued at the time of temporarily leaving the entrance management device 1 is loaded into the card input device 12, and the confirmation of the card and the index of the finger information are input. Further, the finger information is collected again by the finger information collection and authentication device 14, and the finger information registered in advance in the database 3 is indexed based on the index to perform the finger verification. As a result of the collation, when they match, the temporary exiting person is re-entered, the gate opening / closing control device 11 is controlled to open the gate, and the entrance is permitted.

Further, at the time of temporary leaving, database information can be made unnecessary by writing finger information on the ticketing card. In addition, the present invention can manage not only how many people enter and exit the venue, but also how many times the person has received the service. That is, it is realized by inputting finger information before receiving the service, collating it with the finger information on the database 3 to find out the number of times, and updating the number of accesses related to the finger information on the database 3. This can prevent duplicate distribution to the same person, for example, when distributing a sample.

[0029]

As described above, according to the present invention, by temporarily collecting finger information at the time of temporary leaving and registering it in a database for storing and managing the finger information for a certain period of time, by performing finger authentication collation at the time of re-entry, temporary Since it is possible to distinguish between a leaver and a new visitor, temporary exit management can be mechanized with high reliability without requiring special ink stamping or stamping. Further, by issuing a card at the time of temporary leaving and assigning an index, it is only necessary to collate with the finger information corresponding to the index, so that the time required for finger authentication can be reduced. Further, by writing a part of the information on the card, a relatively small database can be handled.
