Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal identification device for identifying an individual on the basis of a human characteristic such as a fingerprint, a palm print, or a voice print capable of identifying the individual.

[0002]

2. Description of the Related Art Conventionally, a system that functions on the premise of identifying an individual (user), for example, an access control system for a host computer of a network or a computer in a company, or an individual in an electronic payment system used in a financial institution, etc. As the identification means, I
The method of using a D number (user identification number) and a password is most popular. However, this password method has an advantage that it has a simple structure, but has a problem that the security is low in reliability such that the password may be known to a third party.

Therefore, in recent years, the reliability of security is greatly improved by identifying an individual by utilizing the human characteristics (fingerprint, palm print, voice print, capillary blood vessel pattern of the retina, etc.) unique to each individual. The personal identification device thus made is put to practical use. That is, for example, a personal identification device using a fingerprint generally includes a terminal device that converts a fingerprint pattern into image data, and a storage device for registering fingerprint data of a specific individual in a state of being associated with an ID number. Is provided, and when the ID number is input through the terminal device, the I
The registered fingerprint data corresponding to the D number is collated with the characteristic points of the image data from the terminal device, and the individual is identified based on the collation result.

[0004]

There is a technical circumstance that a comparatively long time (about 2 seconds) is required for the collation of fingerprints as described above. For this reason, in the conventional personal identification device, when a plurality of terminal devices are provided, when fingerprint verification requests are simultaneously made from a plurality of terminal devices, it is necessary to wait for the verification operation in order, and However, there is a drawback in that the time required for the identification operation of, that is, the waiting time on the side of the user who is the operator becomes unreasonably long.

The present invention has been made in view of the above circumstances, and an object of the present invention is to improve reliability of security by identifying an individual based on a human body characteristic. An object of the present invention is to provide a personal identification device that enables quick identification operations even if personal identification requests are made at the same time.

[0006]

In order to achieve the above object, the present invention detects a human body feature capable of identifying an individual in a personal identification device for identifying an individual based on the human body feature. To identify the individual by collating the detection data from the terminal device with the human characteristic data registered in the storage means. And a control device that is connected to the terminal device via a network and sequentially applies detection data from each terminal device to the plurality of verification devices to operate the verification devices in parallel. It is what

[0007]

The terminal device detects a human body feature that can identify an individual and gives the detected data to the control device via the network. When the detection data is output from the plurality of terminal devices at the same time, the control device sequentially applies the detection data to the plurality of collating devices and causes the collating devices to operate in parallel. In this case, the individual is identified by collating the detection data with the human body characteristic data registered in the storage means. As a result, when there are individual identification requests from a plurality of terminal devices at the same time, the individual identification operations through those terminal devices are distributed and executed, and the time required for the identification operation is shortened. Become so.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to an access control system in a computer network will be described below with reference to the drawings. FIG. 1 shows the entire system configuration by combining functional blocks. In FIG. 1, a plurality of computers 1-1, 1-2, ... 1-n are connected via a network 2 so that they can access each other through a login process and a remote login process which will be described later. It has become. Each computer 1-1, 1-2, ... 1-n has
Fingerprint input section 3-1, 3-corresponding to the terminal device in the present invention
2, ... 3-n are connected, especially computer 1-1
A control unit 4 corresponding to the control device according to the present invention is connected to the.

The fingerprint input sections 3-1, 3-2, ... 3-n are of a well-known structure in which a light source, a triangular prism, a CCD element, an A / D converter, etc. are combined, and an individual operator is specified. The fingerprints, which are possible human characteristics, are detected as image data, and the matching data obtained by A / D converting the image data is used by the corresponding computer 1-1, 1-2,
… It's supposed to be given to 1-n.

A memory device 5 and a plurality of collating devices 6-1, 6-2, ... 6-n are connected to the control unit 4. In this case, the storage device 5 has a computer 1-
Fingerprint data of predetermined fingers (human body characteristic data in the present invention) relating to a plurality of specific individuals who are permitted to use 1, 1-2, ... 1-n are ID numbers previously assigned to the specific individuals. It is registered in the state of being associated with. Also,
The collating devices 6-1, 6-2, ... 6-n include the fingerprint input unit 3-1,
It is provided to identify the individual by collating the collation data from 3-2, ... 3-n with the registered fingerprint data of the storage device 5.

In the following, a normal login process in the system shown in FIG. 1 will be described.
Note that the normal login process here means the fingerprint input unit 3
-1, 3-2, ... 3-n through the corresponding computer 1-1,
1-2, ... Indicates logging in to 1-n, but here,
The case where the computer 1-2 logs in through the fingerprint input unit 3-2 will be described as an example.

That is, in FIG. 2 showing the flow of the normal login process, the computer 1-2 receives a login request (specifically, an ID number is input through, for example, a keyboard or an ID card not shown). If so, a fingerprint input request is made to the fingerprint input unit 3-2 (steps A1, A2). Then, the fingerprint input section 3-2
Then, "fingerprint input process" and "data transfer process"
Are sequentially executed (step A3).

Specifically, as shown in FIG. 4, the fingerprint input unit 3-2 detects the operator's fingerprint as image data in the "fingerprint input process" performed in response to the fingerprint input request, and In the subsequent "data transfer process", the image data is A / D converted and the A / D conversion is performed.
Control is performed to transfer the image data after D conversion to the computer 1-2 as collation data.

Returning to FIG. 2, the computer 1-2, which has received the collation data transferred from the fingerprint input section 3-2 as described above, sends the collation data to the computer 1-1 together with the ID number. Transfer and request verification (step A)
4). The computer 1-1 which has received the collation request transfers the collation data and the ID number to the control unit 4, and answers the fingerprint collation result, which will be described later, through the control unit 4 to the computer 1-2. (Step A5).

In the computer 1-2 which has received such answer back, when the fingerprint collation result is "OK", the login process for permitting the use start is performed,
When the fingerprint collation result is "NG", the process of rejecting the login is performed (step A6), and the normal login process is performed as described above.

Next, the remote login process in the system shown in FIG. 1 will be described. Note that the remote login process here refers to logging in to another computer from a computer that has already completed the normal login process as described above, but here, from the computer 1-2 that has already logged in. A case of logging in to the computer 1-3 will be described as an example.

That is, in FIG. 3 showing the flow of the remote login process, the computer 1-2 issues a remote login request to the computer 1-3 (step B).
1). It should be noted that such a remote login request can also be sent to an ID through a keyboard or ID card (not shown).
This is done by entering the number.

When the above remote login request is made, the computer 1-3 requests the computer 1-2 for the collation data of the operator's fingerprint (step B2). Then, the computer 1-2 displays the fingerprint input unit 3
The fingerprint input request for -2 is generated (step B3), and accordingly, the fingerprint input unit 3-2 sequentially executes the "fingerprint input process" and the "data transfer process" shown in FIG. Then, the matching data corresponding to the fingerprint of the operator is transferred to the computer 1-2 (step B4).

The computer 1-2 having received the collation data from the fingerprint input unit 3-2 in this manner transfers the collation data to the computer 1-3 which has made a login request (step B5). In response, computer 1-3
Transmits the collation data transferred as described above to the computer 1-1 together with the ID number at the time of the login request to make a collation request (step B6). The computer 1-1 which has received this verification request receives the verification data and the I
The D number is transferred to the control unit 4, and the fingerprint collation result, which will be described later, performed through the control unit 4 is answered back to the computer 1-3 (step B7).

In the computer 1-3 which has received such answer back, when the fingerprint collation result is "OK", the login process for permitting the use start is performed,
When the fingerprint collation result is "NG", the process of rejecting the login is performed (step B8), and the remote login process is performed as described above. It is needless to say that the normal login process and remote login process as described above can be similarly performed between any one of the computers 1-1, 1-2, and 1-n.

In the following, the collating devices 6-1 and 6 will be described.
The fingerprint collation function by -2, ..., 6-n and the control content by the control unit 4 will be described with reference to FIGS. First, referring to FIG. 5, collation devices 6-1, 6-2, ...
The 6-n waits in an idle state until the registered fingerprint data and the matching data are set through the control unit 4 (step C1), and when the registered fingerprint data and the matching data are set, the 6-n verifies itself. A BUSY flag indicating that the operating state has been entered is set (step C2). Next, a matching process is performed in which the registered fingerprint data and the matching data are compared to determine whether they match (step C3), and the matching result (if the registered fingerprint data and the matching data are matched, “ “OK”, and “NG” if they do not match (step C4),
An end flag indicating that the collating operation is completed is set (step C5).

After that, after confirming that the collation result set as described above has been read by the control section 4, the BUSY flag and the end flag are reset (steps C6 and C7), and the initial idle state is restored. Return.

On the other hand, in FIG. 6 showing the control contents by the control unit 4, the control unit 4 waits in an idle state until there is a collation request, that is, until collation data and an ID number are input from the computer 1-1. (Step D1) When the collation data and the ID number are input, the input data is fetched into a buffer memory (not shown) of the device in association with a predetermined data address, and the registered fingerprint data corresponding to the input ID number. Is read from the storage device 5 and loaded into the buffer memory in association with the data address (step D).
2).

Next, a plurality of matching devices 6i (i = 1, 2
, ... n) are in the BUSY state
When the extracting operation is executed by scanning the flag (steps D3-1, D3-2, ... D3-n) and the collation device 6i in the resting state in which the BUSY flag is reset is extracted, the collation device 6i is extracted. The registered fingerprint data and collation data in the buffer memory are set (steps D4-1, D4-2, ... D4-n). As a result, the collating device 6i executes the collating operation as described above, and BUSY is executed during the collating operation.
The flag is set and the end flag is set at the end of the matching operation.

The control unit 4 executes the step D4-
After executing D1, D4-2, ... D4-n, the collation device 6 is scanned by scanning the end flag of each collation device 6i.
Whether or not the collation result is output from i is detected (step D
5). At this time, if there is no matching device 6i that has output the matching result, it is determined whether or not there is another matching request (step D6). If "YES" is determined in this step D6, that is, if there is another collation request in a state before the collation device 6i outputs the collation result (a state in which the collation device 6i that outputs the end flag does not exist). Re-executes the control from step D2 onward, extracts another collation device 6i in the idle state, and causes the collation device 6i to start the collation operation.

When the control unit 4 detects the collation device 6i for which the collation operation is completed ("YE" in step D5).
In S "), the collation result is notified to the computer 1-1 (steps D7, D8, D9), and then the initial idle state is returned.

In summary, when a plurality of collation requests are made through the computer 1-1, the control section 4 sends the registered fingerprint data and the collation data given in response to the collation requests to the collation device 6i which is in a dormant state. By sequentially passing the fingerprints, the individual identification operations through the fingerprint input units 3-1, 3-2, ... 3-n are executed in a distributed manner.
Therefore, even when a plurality of collation requests are issued at the same time, the time required for the identification operation is shortened, and it is possible to prevent the waiting time on the user side from being unduly long.

Although the above embodiment is an example in which the present invention is applied to an access control system in a computer network, it may be applied to an access control system for a single computer and also to an electronic payment system. Of course it is possible,
In this case, "O
The process of “K” / “NG” may be replaced with “OK” / “No” for electronic payment.

In addition, the present invention is not limited to the above-mentioned embodiments, and for example, a palm print, a voice print, a capillary blood vessel pattern of the retina, or the like may be used as a human body feature capable of identifying an individual. The present invention can be variously modified and implemented without departing from the gist thereof.

As is apparent from the above description, according to the present invention, a plurality of collating devices for identifying an individual based on human characteristics are provided, and the above collating device is used when a plurality of collating requests are made. Since a control device for operating in parallel is provided, the reliability of security is improved by identifying an individual based on the human body characteristics as described above, but the same device from multiple terminal devices is used. The identification operation can be quickly performed when there is a personal identification request at a certain time, and the waiting time on the operator side can be shortened.
