Abstract

PROBLEM TO BE SOLVED: To improve a function by discriminating a certified person from a registered person at the time when a registered person falls in agreement by a living body key certification means with a prescribed threshold value and a nonliving body key certifica tion means. SOLUTION: A person certification device is constituted of, for instance, a living body key certification part 1 with a key of a face, a nonliving body key certification part 2 with a key of a radio wave tag, a discrimination part 3, and an output part 4. Next, the certification part 1 recognizes on input face image of a person to be certified, by a threshold value in which the person passing rate is maximized. Next, the certification part 2 inputs a radio wave signal of a radio wave tag device which the person to be certified carries with, when a signal strength is at least a prescribed threshold value, the signal is decoded to obtain a tag ID, and if a person registered corresponding to the tag ID exists, ID of the person is outputted. The discrimination part 3 outputs a person ID in the case where the person ID by the certification parts 1, 2 agree with each other, and the output part 4 outputs the person ID to the outside of the device. Thereby a registered person having a justifiable nonliving body key can pass surely, while a person to be certified who has obtained a nonliving body key illegally can be refused.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for authenticating a person, and more particularly to an apparatus and a method for authenticating an individual using a biometric key and a non-biological key.

[0002]

2. Description of the Related Art (First Problem) Conventionally, as a method of authenticating an individual, an encryption key such as an IC card / magnetic card / wireless card is stored in a computerized form, and a device key capable of reading out the encryption information. Authentication (including broadly those that use the physical characteristics of the device itself such as a lock as a key), authentication using an encryption key such as a password, and biometric keys such as a fingerprint / voiceprint / palmprint / iris / retina / face Certification has been proposed.

[0003] A personal authentication method using a non-living key such as an equipment key or an encryption key can authenticate the presenter of the non-living key without ambiguity, but is illegal to another person due to loss / theft of the equipment key or leakage of the encryption key. There is a risk of being used. On the other hand, the personal authentication method using a biometric key has a feature that the biometric key is inseparable from the individual and thus is difficult to use illegally.
Adjusting the security system so as to eliminate unauthorized users may cause a problem that even authorized users are rarely excluded.

[0004] The cause is that the biometric key is a pattern feature,
This is because authentication of the biometric key is performed by pattern recognition. In the personal authentication using a biometric key, a similarity is obtained by comparing an input biometric key of the input subject with a dictionary biometric key of the registrant, and the registrant who has obtained a maximum similarity equal to or greater than a predetermined threshold is referred to as the subject. Recognition is performed as a certifier, and others are rejected. At this time, the maximum similarity is the first similarity,
If the registrant who obtains the maximum similarity is called the first candidate, each of the first candidates is the person to be authenticated and the first similarity is equal to or greater than a predetermined threshold, and correct authentication is performed. Condition. Further, it is a condition for correct rejection that the first place candidate is not the person to be authenticated and that the first place similarity is less than a predetermined threshold.

[0005] As exemplified in FIG. 5, the rate at which correct authentication is performed when the threshold value is variously changed, that is, the pass-through rate 61 is monotonically between 100% and 0% as the threshold value increases. Decrease. Further, the rate at which correct rejection is performed when the threshold value is variously changed, that is, the false exclusion rate 62 monotonically increases from 0% to 100% as the threshold value increases. Both trajectories are non-maximum values 6
In general, they cross at 3, and there is no threshold that can be maximized.

At this time, if the threshold value is set to a high similarity range in which the exclusion rate is maximized, unauthorized users can be rejected most often, but since the pass-through rate is not maximum, the registrant is unjustified. We cannot minimize rejection. On the other hand, if the threshold is set to a low similarity range in which the personal pass rate is maximized,
Although the registrant can be passed the best, the passing of unauthorized users cannot be minimized because the exclusion rate is not the maximum.
For this reason, in person authentication using a biometric key, it is impossible to achieve both reliable authentication of a registered person and reliable rejection of a person other than the registered person.

In order to solve this problem, it is conceivable to perform personal authentication by using the authentication result of each of the biometric key and the non-biological key together. However, the effect of the combination of the biometric key and the non-biometric key is exhibited. The first problem in the prior art is that the usage to be obtained is not well established.

(Second Problem) Also, the biometric key and the non-biological key have different input methods. The subject must enter the biometric key and the non-biological key into the system during a series of operations for authentication. In spite of ergonomic issues, labor saving and improvement of comfort at that time, or pursuit of inevitable device structure based on human posture or habits when using human body structure and system are The second problem in the prior art is that the study for that purpose has not been sufficiently conducted.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a person authentication apparatus and method according to the present invention will be described with reference to the drawings. (First Embodiment) A first embodiment of a person authentication apparatus and method according to the present invention will be described. FIG. 1 is a diagram showing a block configuration of the apparatus of this embodiment. The apparatus of this embodiment includes a biometric key authentication unit 1, a non-biometric key authentication unit 2, a discrimination unit 3, and an output unit 4.
Consisting of FIG. 2 shows a processing configuration in the apparatus of this embodiment. The processing in this embodiment includes a biometric key authentication process S1, a non-biometric key authentication process S2, a discrimination process S3, and an output process S4. The apparatus according to the present embodiment is an example in which a face is used as a biometric key and a wireless tag is used as a non-biometric key.

The biometric key authentication unit 1 (step S1) is a functional block for inputting and recognizing a face image as a biometric key of a person to be authenticated. An inspection area is provided in an image, an image pattern in the inspection area is checked against a face pattern template while scanning the inspection area in an input image, and an inspection area having a maximum correlation value equal to or greater than a predetermined threshold is defined as a face area. The image in the area is extracted as a face image pattern, and the face image pattern thus periodically extracted is always held in a predetermined plurality, and the held face image pattern is stored in a predetermined size and brightness range. Into a normalized face image pattern, generate a correlation matrix from the predetermined plurality of normalized face image patterns, apply this to the principal component analysis, and convert the subspace based on the eigenvectors obtained as a result to the Predetermined multiple normalization An input subspace representing an image pattern is formed, and a maximum cosine between the input subspace and a dictionary subspace prepared for each registered person (registered person) is obtained as a similarity. The dictionary subspace that has obtained the maximum similarity is selected, and the registrant corresponding to the selected dictionary subspace is determined to be the authenticatee, and the person ID of the registrant is output. If there is no dictionary subspace for which the degree has been obtained, there is no registered person corresponding to the person to be authenticated, and a special person ID indicating that there is no corresponding person.
Is output.

At this time, as shown in FIG. 5, the predetermined threshold value is the similarity region (64
May be set somewhere on the left), but the lower the threshold is set, the lower the exclusion rate becomes. Therefore, it is desirable that the threshold be as high as possible. Ideally, the threshold value is set to 64 in the figure where the personal pass rate 61 starts to decrease from the maximum value 65. At this time, the stranger exclusion rate is 66 in the figure, which is smaller than the maximum value.

The non-living key authentication unit 2 (step S2) is a functional block for inputting and decoding a wireless signal of the wireless tag device as a non-living key carried by the person to be authenticated, and a wireless signal generated by the wireless tag. When the intensity of the wireless tag becomes equal to or greater than a predetermined threshold, the signal is decoded to obtain the tag ID of the wireless tag,
If there is a registered person corresponding to the tag ID, the person ID
If not, a special person ID representing no corresponding person is output.

The discriminating unit 3 (step S3) outputs the matched person ID which is the authentication result only when the person ID by the living body key authenticating unit 1 and the person ID by the non-living key authenticating unit 2 match. If they do not match, a special person ID indicating rejection is output.

The output section 4 (step S4) outputs the person ID from the discrimination section 3 to the outside of the apparatus.

The apparatus according to the present embodiment having the above configuration uses an authentication logic that authenticates if the authentication result of the biometric key and the non-biometric key match, otherwise rejects the authentication. , The following [Effects 1 to 3] are exhibited.

[Effect 1] A registrant (authorized user) having a valid non-biological key can be set by setting a similarity threshold value that maximizes the probability that the registrant is correctly authenticated (passing rate). Can be reliably passed when the biometric key matches the non-biometric key.

[Effect 2] An authenticated person (illegal user) who has illegally obtained the non-living key is usually authenticated as a registrant different from a legitimate holder of the non-living key in authenticating the living key. Therefore, there is a high possibility that the biometric key is rejected because of a mismatch between the biometric key and the non-biometric key.

[Effect 3] The authorized user can receive the authentication of the biometric key and the non-biometric key in parallel, and enjoys the comfort that minimizes the total waiting time from the start to the completion of the authentication. It becomes possible.

As a result, the maximum authentication of the authorized user and the maximum rejection of the unauthorized user are both realized, and the reliable authentication and comfort of the authorized user and the security for the unauthorized user are made parallel. It becomes possible.

The biometric key by the biometric key authentication unit 1 and the non-biometric key by the non-biometric key authentication unit 2 are not limited to the above examples. (Second Embodiment) A second embodiment of the person authentication apparatus and method according to the present invention will be described. FIG. 3 is a diagram showing a block configuration of the apparatus of this embodiment. The apparatus of this embodiment includes a non-living key authentication unit 11, a living key authentication unit 12, and an output unit 13. FIG. 4 shows a processing configuration in the apparatus of this embodiment. The processing in this embodiment includes a non-living key authentication processing S11, a living key authentication processing S12, and an output processing S13. The apparatus according to the present embodiment is an example in which a face is used as a biometric key and a wireless tag is used as a non-biometric key.

Non-living key authentication unit 11 (step S11)
When the strength of a wireless signal emitted by the wireless tag, which is a non-biological key carried by the subject, is greater than or equal to a predetermined threshold, the signal is decoded to obtain the tag ID of the wireless tag, and the tag ID is assigned to the tag ID. If there is a corresponding registrant, the person ID is output, and if not, a special person ID indicating no corresponding person is output.

The biometric key authentication unit 12 (step S12)
If the non-living-body key authentication unit 11 receives an unrelevant person ID, the person ID is output as it is. Otherwise, the image is input periodically to form an input image. An inspection area is provided, and while the inspection area is scanned in the input image, an image pattern in the inspection area is compared with a face pattern template, and an inspection area having a maximum correlation value equal to or greater than a predetermined threshold value is regarded as a face area. Then, an image in the area is extracted as a face image pattern, the face image pattern thus periodically extracted is always held in a predetermined plurality, and the held face image pattern is normalized to a predetermined size and brightness range. Into a normalized face image pattern, generate a correlation matrix from the predetermined plurality of normalized face image patterns, perform a principal component analysis on the correlation matrix, and convert the subspace based on the eigenvectors obtained as a result into the predetermined plurality of The normalized face of An input subspace representing an image pattern is formed, and a maximum cosine between the input subspace and a dictionary subspace corresponding to a person ID by the non-living key authentication unit 11 is obtained as a similarity, and the similarity is equal to or greater than a predetermined threshold. When the number is less than the predetermined threshold value, the special person ID indicating that there is no corresponding person is output.

At this time, as shown in FIG. 5, the predetermined threshold value is the similarity region (6
4 (left side of FIG. 4), the lower the threshold is set, the lower the exclusion rate becomes. Therefore, it is desirable that the threshold be as high as possible. Ideally, the threshold value is set to 64 in the figure where the personal pass rate 61 starts to decrease from the maximum value 65. At this time, the stranger exclusion rate is 66 in the figure, which is smaller than the maximum value.

The output unit 13 (step S13) outputs the person ID from the biometric key authentication unit 12 to the outside of the device.

The apparatus according to the present embodiment having the above-described configuration can achieve both high authentication reliability and high security by the same [Effect 1] and [Effect 2] as the apparatus of the first embodiment. The following new [Effect 4] can be obtained.

[Effect 4] The biometric key authentication can be performed at a high speed with a reduced calculation cost because the biometric key authentication only needs to be collated with the single registrant indicated by the non-biometric key authentication result. Since the collation is performed with only one registered person, the risk of an authentication error is reduced, and the reliability of the authentication result is improved.

It should be noted that the non-living key by the non-living key authentication unit 11 and the living key by the living key authentication unit 12 are not limited to the above example. (Sensor Arrangement) Next, a description will be given of a sensor arrangement provided in the person authentication apparatus according to the present invention, that is, an arrangement of a photographing unit for inputting a face image as a living body key and an arrangement of a receiving unit for inputting a radio signal as a non-living body key. I do. From the relationship between the height of the device and the height of the person to be authenticated, there are generally two types of sensor arrangements in the person authentication device according to the present invention, as shown in FIGS. 7 and 8. (First Sensor Arrangement) FIG. 7 shows a first sensor arrangement. In the figure a, the person to be authenticated 101 stands upright and the device 1
02, and the height of the device 102 is made substantially equal to the height of the person to be authenticated 101 so as to induce such a posture.

Normally, the wireless tag 105 is considered to be worn at the height from the waist to the chest of the person to be authenticated, so that the face is at a high position and the wireless tag is at a lower position when viewed from the device 102. . At this time, the receiving sensitivity area 104 of the receiving means 107 provided in the non-living key authentication unit that should receive the wireless signal of the wireless tag must be set in front of the apparatus, in a range covering the waist from the chest of the person to be authenticated. For this reason, the receiving means 107 is arranged at a height substantially at the center of the height of the subject 101 from the hip to the chest.

On the other hand, the photographing means 1 provided in the biometric key authentication unit
The field of view 103 at 06 must be set so that an upright face is placed in it. For this reason, the photographing unit 106 is installed substantially at the same height as the assumed height of the face of the person to be authenticated 101 and facing the front. At this time,
Since the face of the person to be authenticated 101 is at a position higher than the wireless tag, the photographing means 106 is necessarily installed at a position higher than the receiving means 107.

It is considered that the wireless tag 105 is often put in a breast pocket of clothes of the person 101 to be authenticated, or worn like a badge on the chest or waist according to the rules of the group of the person to be authenticated. At this time, the wireless tag 105 is off the body axis of the person 101 to be authenticated,
Is placed on the body axis, the face image and the tag ID can be input at the same position by the person to be authenticated. Therefore, as shown in FIGS. It is installed so that it may not be on the same straight line with respect to the assumed body axis of the authenticator 101, that is, the vertical direction of the device 102. In particular, the direction in which the receiving means 107 is shifted is the wireless tag 1
05 is the side that is often mounted, and is usually the left side of the person 101 to be authenticated. Of course, it is also possible to equip two right and left receiving means 107 as shown in FIG. 3C so that the wireless tag 105 may be attached to either side.

By arranging in this way, the following [Effect 5]
7] can be obtained.

[Effect 5] The subject 101 can input the face image and the tag ID at the same position, and the [Effect 3] can be ensured.

[Effect 6] The subject 101 is the device 102
The face image and the tag ID
Can be input simultaneously without any procedure, and the comfort of the person to be authenticated can be further improved.

[Effect 7] Photographing means 106 and receiving means 1
By arranging steps 07 differently, it becomes possible to design the width of the device smaller than when both sensor means are arranged side by side.

In particular, in the device of the first embodiment, the effect 5 and the effect 6 allow the input of the living key and the non-living key to be performed in a non-procedure parallel manner. It is possible to reliably realize the comfort that the authentication is performed in the shortest binding time without making the authentication subject feel the authentication time difference of the key. (Second Sensor Arrangement) The second sensor arrangement is shown in FIG. In FIG. 2A, the subject 101 leans down and looks into the device 102, and the height of the device 102 is made smaller than the height of the subject 101 so as to induce such a posture.

At this time, as described in the first sensor arrangement, the receiving means 107 is arranged at a height almost at the center of the height of the subject 101 from the waist to the chest.

On the other hand, the photographing means 106 is installed upward at a low position in order to photograph the face to be looked into from below. Accordingly, the subject 101 is first authenticated for the tag ID by entering the receiving sensitivity area 104 of the receiving means 107, and then authenticated for the face by looking down at the photographing means 106 with his face down. In order to secure this order, the present sensor arrangement is configured such that the photographing means 106 is installed upward at a low position so that it is difficult to input a face image in the upright state.

At this time, since the bent face and the wireless tag are very close to each other, it is desirable that the photographing means 106 is installed below the receiving means 107. In particular, since the photographing means 106 has a minimum distance at which the image can be clearly photographed due to the restriction of the depth of field, it is better to install the photographing means 106 in this way.
The degree of freedom of adjusting the focal length and the angle of view is obtained.

As in the case of the first sensor arrangement, the wireless tag 105 is put in the breast pocket of the clothes of the person 101 to be authenticated, or is worn like a badge on the chest or waist according to the rules of the group of persons to be authenticated. Since the face image and the tag ID can be input at the same position by the person to be authenticated, the photographing means 106 and the receiving means 107 are connected to the person to be authenticated 101 as shown in FIGS. Is set so as not to be collinear with the assumed body axis, that is, the vertical direction of the device 102.

By arranging in this manner, the above [Effect 5]
[Effect 7] can be obtained as well as the following [Effect 8] can be newly obtained.

[Effect 8] The subject 101 is the device 102
To enter a tag image by entering a predetermined position in front of the user, and then bend the face so that a face image can be input.
And the input order of face images can be naturally guided.

In particular, in the device of the second embodiment, the effect 5 and the effect 8 prevent the subject to be conscious of an increase in waiting time due to the authentication order of the non-living key and the living key. Therefore, it is possible to maintain the comfort while improving the reliability of the authentication according to the [Effect 4].

In the first and second sensor arrangements, the biometric key is not limited to the face but may be, for example, an iris, a retina, or a voice. That is, if the biometric key is obtained from the head of the person to be authenticated, and the sensor means for the acquisition is given directivity toward the head, the above-mentioned [Effects 5 to 8] are similarly obtained.

In the first and second sensor arrangements, the non-living key is not limited to the wireless tag, but may be, for example, a personal identification number or an ID.
It may be a C card, a magnetic card, or a lock key. This is because these non-living keys are input by the motion of the hand of the subject, and it is natural that the motion of the hand is performed near the height of the center from the waist to the chest. [Effects 5 to 8] can be similarly obtained as long as the non-living key is input at such a height of the subject.

In the first and second sensor arrangements, the person to be authenticated 101 may be in a sitting position instead of a standing position. In short, in the present sensor arrangement, the face of the person to be authenticated 101 is substantially facing the front, and the sensor arrangement according to the position of the face and the position of the wireless tag at that time can be taken.
In the sensor arrangement of the above, the biometric key and the non-biological key can be input immediately by entering the position where the subject 101 can input,
In the second sensor arrangement, the non-living key can be input first by entering the position where the subject 101 can enter, and then the biometric key can be input by the bending operation of the subject.

The device housing 102 for realizing the first and second sensor arrangements does not need to be placed on the floor as illustrated, but may be fixed to a wall or ceiling, for example, or may be the subject to be authenticated. However, the present invention can be implemented as a portable device, or as a separate sensor unit. In short, in the present invention, the above [Effect 5]
As long as the sensor means can be installed in the above-described arrangement so as to exhibit [8], differences in the shape and fixing method of the device housing do not matter. (Appearance of Apparatus) FIG. 9 shows an example of the appearance of a person authentication apparatus according to the present invention. In the figure, a is the appearance of the device that can be fixed to the floor, and b in the diagram is the appearance of the device that can be fixed to the wall. At this time, the sensor means 106 for inputting the living key and the sensor means 107 for inputting the non-living key are attached to the rotatable housing section 108, and the fixing section 10 for fixing the apparatus is provided.
9 secures to the floor or wall. Housing part 10
8 and the fixed portion 109 are rotatable at a boundary portion 110 in the drawing, and the rotation range is indicated by 111 in the drawing.

The following [Effect 9] can be obtained by making the housing portion 108 of the sensor rotatable with respect to the installation portion 109 in this manner.

[Effect 9] In accordance with the flow line of the person to be authenticated in the environment where the apparatus is installed, the direction of the sensor can be adjusted independently and easily from the direction of the installation part so that the person to be authenticated can be authenticated on the flow line. Thus, it is possible to improve the comfort of the person to be authenticated.

The present device installed near the flow line of the person to be authenticated achieves the following [Effects 10 to 11].

[Effect 10] The device housing is formed in a shape incorporating a large number of curved surfaces, so that the body of the person to be authenticated can be prevented from being damaged when an accidental collision by the person to be authenticated occurs.

[Effect 11] A protective cover 11 is provided for each sensor.
2 is attached so that the collision does not damage the sensor means.

The housing section 108 of the sensor can not only pan (horizontal rotation) around the vertical axis as described above, but also can tilt up and down (vertical rotation). Further, the housing portion 108 can be movable, for example, up, down, left and right, instead of rotating. That is, as long as the housing unit 108 is independently movable with respect to the fixed unit 109, and as a result, the person to be authenticated can be captured on the flow line, the difference in the degree of freedom of movement does not matter.

It is also possible that the input means of the living key and the input means of the non-living key are housed in separate housing parts, and each housing part is movably supported by a separate fixing part. .

In the device having one fixing portion as in the above a, the housing portion 108 and the fixing portion 109 can be fixed by suspending from the ceiling by exchanging the vertical relationship between the housing portion 108 and the fixing portion 109. It is also possible to fix it to the wall.

Also, in the device having two fixing portions as in the above-mentioned b, it is possible to fix to the ceiling or the floor instead of the wall.

The housing may be moved by a human hand, moved by a machine, for example, by a motor, or automatically moved by a device. (Arrangement of devices focusing on flow lines) A person authentication device that uses both a biometric key and a non-biological key is applied to a security gate system that permits only authenticated persons to pass and rejects other persons. Consider the case. In this case, it is particularly important to consider the flow line because the use form in which the person to be authenticated moves toward the gate to be authenticated and passes through the gate as it is is ideal.

FIGS. 10 to 12 show examples of the environment in which the personal authentication device is installed. FIG. 10 shows the case where the gate is at the end of the passage, FIG. 11 shows the case where the gate is at the corner of the passage, and FIG. 12 shows the case where the gate is at the middle of the passage or on the wall of the square. In each of the figures, the upper row a is a perspective view of the gate as viewed from the front, and the lower row b is a top view.

In the figure, 201 is a floor, 202 is a ceiling, 203
205 to 207 to 208 are walls, and 206 is a gate door. In the figure, reference numerals 301, 401, and 501 denote persons, 302 and 303 denote ganglia of the person 301, and 402 and 40, respectively.
3 is a flow line of the person 401, and 502 and 503 are flow lines of the person 501. Of these, 302, 402, and 502 are flow lines for the persons 301, 401, and 501 to pass through the door 206, respectively. At this time, the person authentication device applied to the security gate system must be able to authenticate the persons 301, 401, and 501 on the flow line for passing through the door 206.

When the door 206 is located at the back of the passage as shown in FIG. 10 and the person 301 proceeds along the passage toward the door 206, it is assumed that the person 301 intends to pass the gate with the progress. Can be considered. Therefore,
The person authentication device is a person 3 approaching the gate on the flow line 302.
01 only needs to be authenticated.

On the other hand, as shown in FIGS. 11 and 12, when there is a flow line that does not pass through the gate, it is not possible to consider the approach of a person as the intention to pass. Specifically, the person authentication device is required to authenticate only the persons on the flow lines 302, 402, and 502.

In any case, by installing the person authentication device as shown in FIGS. 7 and 8 in the vicinity of the gate door 206 so as not to obstruct the flow line, the person to be authenticated 301, 401,
501 moves on the flow lines 302, 402, and 502 to the front of the apparatus, stops at a predetermined position on the front of the apparatus, receives authentication, and can pass through the door 206 after authentication. An installation example for this is illustrated in FIG. 341 and 342 in the figure
Are flow lines for the person to be authenticated to pass through the door 206, and 351 and 352 in the figure are personal authentication devices. In FIG. A, the person authentication device 351 is installed on one side of the door 206, and the person to be authenticated moves along the flow line 341 and can stand still in front of the device 351 to be authenticated. Figure b
In, the person authentication device 351 is installed near the center of the door 206, and the person to be authenticated
2 and can stand still in front of the device 351 to be authenticated. In the figure c, the person authentication devices 351 and 352 are installed on both sides of the door 206, and the person to be authenticated moves along the flow line 341 or 342, and stops in front of the device 351 or 352. Can be certified.

In any of the examples, the present arrangement realizes the following [Effects 12 to 13].

[Effect 12] Person authentication devices 351 and 35
Reference numeral 2 denotes the flow lines 303, 403, and 5, which are installed beside the flow line of the person to be authenticated and near the gate door 206, and do not prevent the person to be authenticated from passing through the gate.
03 can be ignored.

[Effect 13] The subject is the flow lines 302 and 4
02 and 502 (indicated by reference numerals 341 and 342 in FIG. 13) to the front of the apparatus and receive authentication, thereby notifying the apparatus of the intention to pass the gate. (Arrangement of Separate Sensors Focusing on Flow Lines) However, in the above-described installation method, the person to be authenticated must temporarily stop in front of the person authentication device near door 206 to be authenticated. In order to provide a more comfortable feeling of use, it is desirable to realize authentication that does not hinder the subject's walking as much as possible.

Here, considering the first embodiment, the following considerations hold.

When authenticating the face of the person to be authenticated, the biometric key authentication unit extracts a face image pattern having a high correlation with the face pattern template from the input image. At this time, since the size of the face pattern template is fixed, the size of the face in the input image from which the face pattern template can output a correlation value equal to or greater than a predetermined threshold is approximately in a constant range (the boundary is If the size is out of this range, the correlation value between the face pattern and the face pattern template decreases. Here, the photographed image of the face becomes smaller as the distance between the photographing means and the face becomes longer, and becomes larger as the distance becomes closer. Therefore, the distance between the face and the photographing means from which the face pattern template can output a correlation value equal to or larger than a predetermined threshold has a substantially constant range. The range in which the person to be authenticated can be located within this distance range is called a face detection range (generally, a biometric key detection range). That is, the biometric key authentication unit can authenticate only the face of the person to be authenticated within the face sensing range.

When the strength of the wireless signal of the wireless tag device carried by the person to be authenticated becomes greater than or equal to a predetermined threshold value, the non-living key authentication unit decrypts the signal and acquires the tag ID of the wireless tag. At this time, since the strength of the wireless signal attenuates in accordance with the distance between the receiving means and the wireless tag, the predetermined threshold defines a spatial range around the receiving means in which the signal of the wireless tag can be decoded. The range in which the person to be authenticated can be positioned so as to insert the wireless tag into the wireless tag is called a wireless sensing range (generally, a non-living key sensing range). That is, the non-living key authentication unit can authenticate only the wireless tag of the subject in the wireless sensing range.

In the apparatus of the first embodiment, the face sensing range and the wireless sensing range are spatially overlapped with each other,
The person ID by the biometric key authentication unit and the person ID by the non-biometric key authentication unit can be obtained almost simultaneously. FIG. 14 schematically shows this. The upper part a of the figure is a perspective view of the gate viewed from the front, and the lower part b is a top view. 6 in the figure
Reference numeral 06 denotes a camera center of the photographing unit 601 provided in the biometric key authentication unit, 607 in the figure denotes a camera optical axis of the photographing unit 601, and 605 denotes a view pyramid representing a photographing range of the photographing unit 601. It is. At this time, the face sensing range is the range 603 in the drawing within the visual field pyramid 605, and the wireless sensing range is inside 604 in the drawing. The subject 301 moves toward the gate (from right to left in the figure) while the face sensing range 6
03 and the wireless sensing range 604 at almost the same time. Immediately after the entry, the pass permitting unit determines whether or not to permit passing. In the case of permitting, the door 206 is opened and the person to be authenticated is left as it is. You can pass through the gate by continuing to enter. By setting such a sensing range, a new next [Effect 14] can be obtained while achieving [Effects 1 to 3] and [Effects 5 to 6].

[Effect 14] The person to be authenticated does not need to stop at the front of the apparatus to be authenticated, and is prevented from proceeding by passing through the face sensing range and the wireless sensing range almost simultaneously while proceeding to the gate door 206. Since the user can be authenticated naturally without any trouble, the comfort is improved.

In order to spatially overlap the face sensing range 603 and the wireless sensing range 604, the receiving means 602 is installed near the face sensing range 603. On the other hand, the photographing unit 601 has its face sensing range 603
In order to photograph the face of the person to be authenticated 311 that is farther, that is, farther than the receiving unit 602 can decode the radio signal, and the photographing unit 601 approaches the gate, from approximately the front, It is installed closer to the gate than the receiving means 602 is.

The horizontal distance closest to the door 206 among the outer edges of the face sensing range 603 and the wireless sensing range 604 is represented by L,
Assuming that the average walking speed of the person 311 is S, and that the processing time from when the person 311 reaches the common sensing space until permission to pass through the gate is P, L = S × P. desirable. The authentication of the subject is started when the subject is at least L away from the door,
Assuming that the time required for the subject to move from the door to the position at which the distance from the door becomes L after the authentication is started is ΔT that is sufficiently short, the following [Effect 15] can be newly obtained.

[Effect 15] After the person to be authenticated passes through the common space and is authenticated, the door is unlocked after a sufficiently short time ΔT and the door is allowed to pass, so that the unlocking is waited in front of the door. There is no comfort.

Next, considering the second embodiment, the following considerations hold.

As in the discussion regarding the first embodiment, the non-living key authentication unit has a wireless sensing range, and the living key authentication unit has a face sensing range. At this time, by arranging the wireless sensing range in front of the face sensing range on the flow line, it is possible to obtain the person ID by the non-living key authentication unit prior to the obtaining of the person ID by the biometric key authenticating unit.

FIG. 15 schematically shows this. The upper part a of the figure is a perspective view of the gate viewed from the front,
The lower part b is a top view. Reference numeral 606 in the figure denotes the center of the camera of the photographing unit 601 provided in the biometric key authentication unit.
Reference numeral 07 denotes an optical axis of the camera of the photographing means 601;
A field of view pyramid 05 represents a photographing range of the photographing means 601. At this time, the face detection range is the range 603 in the drawing within the visual field pyramid 605, and the wireless detection range is inside 604 in the drawing. Subject 301
While entering the gate (from right to left in the figure), the user can enter the wireless sensing range 604 at a position 311 and input a person ID by a wireless tag, and then enter the face sensing range 603 at a position 312 to enter the face. You can enter a person ID. At this time, in the face image authentication based on the person ID by the wireless tag, collation with only one dictionary subspace suggested by the person ID is performed to determine whether or not the passage is permitted. In the case of permission, the door 206 is opened. After being opened, the subject can pass through the gate by continuing to enter. By setting such a sensing range, [Effects 1 to 2] and [Effects 4 to
6], and the following new [Effect 16] can be obtained.

[Effect 16] The person to be authenticated does not need to stop at the front of the apparatus and be authenticated. The subject passes through the wireless detection range while proceeding to the gate door 206, and then proceeds through the face detection range. It is possible to receive the authentication naturally and with high precision without being hindered, thereby improving both comfort and authentication certainty.

The above is an example of installation of the sensing range in an installation environment where a door exists exclusively in the back of a passage. On the other hand, if the door is installed at the corner of the passage, in the middle of the passage, or on the wall of the plaza, the flow of traffic that passes through the gate and the flow of traffic that passes by will be mixed, and the willingness of the authenticated person will not be confirmed. Cannot unlock the door. Therefore, by setting the wireless sensing range closer to the door than the face sensing range, the intention of passing is confirmed when a person enters the wireless sensing range.

FIG. 16 shows an example of setting such a sensitivity range. The upper part a of the figure is a perspective view of the gate viewed from the front, and the lower part b is a top view. The wireless sensing range 604 is set closer to the door 206 than the face sensing range 603, and the movements of persons on the flow lines 303 and 403 that do not enter the face sensing range 603 can be ignored, and the movements that enter the face sensing range 603 can be ignored. Even if the face is authenticated by the face direction of the person on the line 503, the intention to pass is confirmed based on the presence or absence of entry into the wireless sensing range 604, and the flow line 503 can be ignored. As a result, the following effects can be obtained.

[Effect 17] By considering the entry into the wireless sensing range as the intention to pass, in the various installation environments exemplified in FIGS. While ignoring, it is possible to perform person authentication without hindering the movement of the subject who has the intention to pass.

The sensor arrangement illustrated in FIGS. 14 to 16 is such that the means 601 for photographing a face image is
Although the means 602 for receiving the radio signal is fixed to each side wall, as long as it does not hinder the flow line for passing through the gate and the face detection range and the radio detection range can be set to the required arrangements, The sensor means may be fixed where and how. However, in a general passage, the places that can be fixed are limited, and each sensor means must be fixed to at least the ceiling or floor, or the side wall, the door itself, the door frame, or the like. By doing so, it is possible to maintain a stable sensing range without obstructing the flow line. (Embodiment by Combination) It should be noted that the person authentication apparatus and method according to the present invention are not limited to the above-described embodiment, and may be implemented in various combinations within the technical scope.

For example, by combining the apparatus of the second embodiment, the sensor arrangement shown in FIGS. 7 and 8 and the movability of the sensor housing shown in FIG. When the biometric key authentication unit that has received the person ID according to the above uses the only dictionary subspace suggested by the person ID to recognize the face image, the biometric key authentication unit of the photographing unit according to the camera angle suggested by the person ID Orientation or height may be adjustable, and a face image may be input and authenticated using a field of view that matches the height of the person. By doing so, the field of view itself can be narrowed, and the face image of a person can be photographed with a considerably large angle using the adjusted camera angle, and a good-quality face image can be obtained. Of course, the input biometric key is not limited to the face image, but may be an iris image or a retinal image, and is particularly effective for an iris image or a retinal image requiring a close-up image. (Description of Embodiment Using Medium) As illustrated in FIG. 4, information (for example, a program) for realizing the personal authentication device and the method thereof according to the present invention is recorded on a recording medium 71, and the recorded information is recorded on the recording medium 71. The device 7 via the recording medium 71
2 or the device 73, or via the communication lines 75 and 76 to the device 73 or the device 74. That is, the present invention is not limited to the above-described embodiment, and can be implemented with various modifications within the technical scope.
