Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem that only the efficiency improvement of verification work and verification processing has been taken into account in previous verification systems, regardless of the need for paying attention most to verification by face information among pieces of information for identifying an individual. <P>SOLUTION: If a subject 1 does not match any person on a blacklist, a facial verification system 3 fulfills its execution and expresses regret for the subject 1, who has been made to feel unpleasant (made to feel discomfort), such that face verification has been performed with the system for suspicion at least once, thus alleviating the annoyance of the subject 1. In addition, an inquiry is made on whether the subject 1 desires a certificate medium 6 indicating that "I am not a suspicious person used for verification", thus further alleviating the discomfort with humor. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a face matching, and more particularly, to a face information system and method for matching a person requiring attention using a face information authentication medium or face information obtained from a subject.
[0002]
[Prior art]
Japanese Patent Application Laid-Open No. H11-265451 discloses a system for collating image information generated by an image input device with image information stored in a database. In this prior art, distributed matching processing is performed in order to efficiently match image information having a relatively large capacity. It should be noted that additional information for explaining image information (a fingerprint is a specific example shown in the official gazette) is added, and when the collation is confirmed in the image information, the additional information is used for a search for specifying a person. Can be
[0003]
However, these systems focus on how to efficiently execute the matching process using image information indicating an individual (corresponding to a subject; also referred to as a subject). The additional information for explanation does not take into account the subject's feelings, but merely gives consideration to the convenience of the examiner.
[0004]
Japanese Patent Application Laid-Open No. 2002-157365 is a system for issuing a certificate. In this prior art, when a certificate expires, a new certificate is issued based on the information of the old certificate read by the certificate information reading means. The old certificate and the new certificate are of the same kind.

JP-A-2002-157365 (pages 7, 10-11, FIGS. 3, 6-7)
[0006]
[Problems to be solved by the invention]
For example, as a predetermined procedure (i.e., as a rule) at a boundary where the jurisdiction changes, such as an immigration inspection at an airport, it is often required to arbitrarily submit a facial information authentication medium indicating the individual.
[0007]
Because we witnessed in the media images of the September 11 terrorist attacks in the United States in the fall of 2001, and compared with the United States, which has rapidly taken countermeasures against terrorism in its own country, there is no sense of crisis and crisis management in its defenselessness. Otherwise, the Japanese police would be under criticism. In addition, as the soccer World Cup is held jointly by Japan and South Korea, measures against hooligans (commonly known as enthusiastic and sometimes violent activists among soccer spectators) have become a hot topic. When spectators began to make noise, the island nation of Japan knew that the mere fuss could eventually turn into a mob.
[0008]
Therefore, it is not possible to pass everyone through without any check (verification), and Japanese public opinion has begun to reach an agreement as a general opinion that some verification must be done. I have.
[0009]
The face information authentication medium submitted by the individual (subject) is stored in the database in advance through a terminal operated by the inspector, in addition to being collated with the individual by the eyes of the inspector (examiner). It may also be used for face matching using personal information requiring attention and face information. In addition, the subject himself / herself may operate the terminal to pass through the pass gate.
[0010]
Despite knowing that such face matching is a rule, people are still suspected, and even if they are not guilty about themselves, they just feel suspicious and amused. I do not think that. If there is an inspector, the inspector first confirms that the submitted facial information authentication medium belongs to the person. At this time, the subject often feels as if he / she sees his / her face, and therefore feels unpleasant.
[0011]
No, it may be irritating because he doesn't hurt himself. This is also a sign of why you must be suspected. Furthermore, it is hardly convinced that the submission of the facial information authentication medium is required without telling the reason. In other words, face information such as a face photograph is the information that can identify the individual most, and the face information is the information most likely to be the subject himself / herself to the subject. Among the information that identifies individuals, despite the need to pay the most attention to collation based on facial information, conventional collation systems have been concerned only with the efficiency of collation work / collation processing. There was a point.
[0012]
On the other hand, scandals continued, for example, in the police, and the media has taken up all of this, which has widened our citizens' distrust of the police system (organization). Then, the distrust that the user did not normally care about is aroused at the moment when the presentation of the facial information authentication medium is requested. This is like a rut, knowing the need, but not feeling sick.
[0013]
In other words, performing face matching is an action for the inspector to fulfill his / her duties, but the difficulty in obtaining psychological cooperation for that is a problem in utilizing the face matching system. there were.
[0014]
However, superficial cooperation may be obtained. With the power of ex officio with the law as a shield. However, the essence of the problem is not whether the cooperation can be obtained even on the surface, and whether the check of face matching can be smoothly and smoothly performed. Rather, the cause was that the psychological follow-up (mental care) was not performed while giving the subject's psychology an opportunity (trigger) to increase distrust.
[0015]
In other words, the problem is that psychological follow-up of the subject is not performed in the face matching system.
[0016]
[Means for Solving the Problems]
The essence of the present invention is that when a subject does not match a person requiring attention, face matching is performed, and at least once a suspicion is made to be unpleasant (it has caused discomfort). ) To demonstrate accountability and apologize to the subject. An apology can be indicated by explaining to the subject without directly saying "Sorry,""Sorry," or "I'm sorry." In other words, this is indirectly equivalent to an apology, because even if you cannot completely eliminate discomfort by fulfilling accountability, the subject seems to be saying, "If that is the case, why not help?" You will show sincerity.
[0017]
In the present invention, a type of caution indicating a type of caution is given to personal information of a person requiring caution including at least face information, and the personal information is grouped for each type of caution required. It has a cautionary person information database stored in advance, and indirectly transfers the face information of the subject from a face information authentication medium optionally submitted by the subject via an examination terminal operated by the examiner or the subject itself. Or a face collation method that is obtained directly from the subject and collated with the face information of the person of interest read out from the person of interest information database in the unit of caution type, wherein the face information When the face information acquisition unit acquires the face information of the subject from the authentication medium or the subject, the face information acquired by the face information acquisition unit and the caution person information database are acquired. The facial information of the person of interest obtained in units of the type of caution is compared with the facial information collating unit by the facial information collating unit. Based on the result of the collation of the facial information collated by the facial information collating unit, the subject The face information determining means determines whether or not the person of interest needs to be matched, and if the acquired subject does not match the person of interest, Acquiring the cautionary type of the cautionary person used for collation from the information database, and creating collation explanation information describing the cautionary type in which the subject's face information was collated by collation explanation information creating means. Along with the collation explanation information created by the collation explanation information creating means, a judgment result is acquired from the face information judgment means and output.
[0018]
The type of caution here refers to, for example, criminals, terrorists, illegal residents, hooligans, etc., which will be different depending on the purpose of use of the face collation system, and whose purpose of use is a person of caution. It is. The face information authentication medium referred to here is a medium that is voluntarily submitted by the subject and provides the face information of the subject to the face verification system. Certificate, qualification license (for example, wireless license, chief technician of telecommunications, dangerous goods handler, etc.), passport, credit card with face photo, employee ID card, student ID card, examination card, basic resident register card, alien registration card And so on. The type of the face information authentication medium and the method of recording the face information are not limited as long as the face information of the subject can be acquired.
[0019]
Executing the accountability to the subject specifically means to output a description of the collation content of “what kind of collation was in fact” and a collation result of “You were not a person requiring caution”. If there is an examiner who operates the examination terminal, this explanation may be transmitted to the subject via the examiner.
[0020]
In addition, the collation explanation information created by the collation explanation information creating means is recorded, and a certification medium issuing means for issuing a certification medium indicating that the subject is not a person requiring attention with respect to the caution type used for collation is further provided. When the information output means outputs the collation explanation information and the collation result, the information output means outputs question information for inquiring whether the subject desires the certification medium, and the subject has the certification When a reply signal regarding a certification medium acquisition request indicating that a medium is desired to be acquired is received, the certification medium may be issued from the certification medium issuing unit.
[0021]
When there is an inspector operating the inspection terminal, the question as to whether or not the certification medium is desired to be issued may be transmitted to the subject via the inspector. In this case, the result of the question transmitted through the examiner is input to the face matching system by the examiner, and if the subject desires the certification medium, the input information is transmitted to the face matching system for the certification medium. Issuance instruction.
[0022]
Here, the proof medium indicates that "as a result of the face matching, the subject was not a person requiring caution (that is, I was not suspicious)." Specifically, for example, when the type of caution is Hooligan, "I am not a Hooligan" is described in the certification medium.
[0023]
According to this proof medium, just saying "I am issuing a proof medium stating" I am not a hooligan ", how about it?" Because the listening itself is already somehow humorous, the subject's feelings are relieved. When the subject feels humor, the subject can forgive, for example, "It is not very popular to be mushy," or "(face matching) is inevitable."
[0024]
In the conventional face matching system, it was not necessary to issue a certification medium. The reason is that the inspection can be performed only by the face collation medium to be inspected, and it is unnecessary at all for the convenience of the inspection side.
[0025]
On the other hand, the proof medium issued by the face matching system according to the present invention is, as it were, calm (nagomi) and humor. In other words, the proof medium is intended to reconcile subjects who have a feeling of "Why should I be suspected?" Humor with consideration for people's feelings.
[0026]
Therefore, humor can often soften people's feelings, and humor is effective in resolving unpleasant feelings that have caused discomfort.
[0027]
Although it is needless to explain why it becomes humor, a suspicious individual (a person in need of attention for the inspector) does not bother to say that he is not a suspicious individual. More specifically, the suspicious person either hides it carefully or creates a suspicious atmosphere as it is, and does not bother explaining it. There is "funnyness (humorousness, mischievousness)" where suspicious people dare to take actions that should not be done, and this is why humor is a humor.
[0028]
From another point of view, if accountability is not fulfilled, for example, if the reason for verification is not explained at all, the examiner will have a sense of resistance to power and a sense of exclusion that will make the inspector feel that way. To the person. On the other hand, for example, he explained the reason, "Actually ...", and showed him the attitude of "I doubted you, even though he was in my duties." It is also expected that the subject will loosen and feel closer to the test side.
[0029]
People's feelings are not logical. If it is correct, you will never gain an understanding. It is important to consider how you can understand and to make an effort. Also, things are not perfect. Because there is always a critic who criticizes any good, one should consider accountability as a way to show one's willingness to do what one performs.
[0030]
Furthermore, a face photograph created from personal face information acquired from the face authentication medium may be added to the certification medium. By doing so, the certification medium can be easily understood by a third party in which the subject shows the certification medium.
[0031]
Furthermore, if the institution that performed the face verification puts its name on the certification medium, it would have been endorsed, so to speak, it is certain that the intimacy with the tester would be much greater than doing nothing.
[0032]
Further, the expiration date of the certification medium may be the expiration date of the face authentication medium. By doing so, when the face authentication medium expires and is renewed, the subject may offer to perform face verification in order to maintain his or her security.
[0033]
By the way, Japanese people, for example, live in island countries where foreigners are relatively rare, and are not accustomed to foreigners with different appearances and appearances, and are not good at them. Foreigners staying in Japan often experience an exclusive gaze from such Japanese. Of course, if you know each other personally, your exclusive gaze will decrease to the point where you do not mind, but it is not so much in public places where the public who knows nothing is overflowing . In such a case, it does not feel good just to feel that you are being seen with an exclusive glance, but if there is an endorsement of an institution that convinces the other party that you showed it, such as a police, it will be I think I should show. In addition, as for the psychology of a person, a sense of security can be obtained even if it seems that way, and a synergistic effect can be expected that if it is more dignified, it will be more and more invisible to suspicious people.
[0034]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, specific embodiments of the face matching system according to the present invention will be described in detail with reference to the drawings.
[0035]
FIG. 1 is a block diagram illustrating a first concept according to an embodiment of the present invention.
[0036]
In the figure, a subject 1 who undergoes face matching may say that his or her face information authentication medium 2 is the subject 1 itself. This is because the face information such as a face photograph is the information that can identify the individual most, and the face information is the information that is most likely to be the subject himself or herself to the subject 1.
[0037]
The subject 1 submits the face information authentication medium 2 to the face matching system 3. The face collation system 3 that has acquired the face information of the subject 1 from the face information authentication medium 2 is collated with the face information of the person requiring attention stored in the person with caution information DB (database) 4, and the collation result is obtained. Output. In the subject 1, a great discomfort occurs once at the time of the face matching. However, in the face matching system 3 according to the embodiment of the present invention, when the face matching does not result in the face matching, the explanation about the face matching is given. Since it is output to the subject 1 as sincerity indicated by the face collation system 3, the subject 1 feels sincerity and understands the explanation, so that discomfort generated in the feelings of the subject 1 Healed.
[0038]
The explanation about the face matching output from the face matching system 3 to the subject 1 usually includes a (mismatched) result, and expresses the gratitude from the gratitude (gratitude information) DB 5 in which the words of gratitude are stored. In some cases, words have been acquired and granted.
[0039]
The cautionary person information DB 4 is a cautionary type indicating what kind of caution is required for the personal information of the cautious person including at least the face information. This is a database in which the personal information is grouped for each and stored in advance. The acquisition of the face information authentication medium 2 may be performed via an inspector 7 generally called an inspector, and in that case, the procedure may be output from the face collation system 3 as an instruction to the inspector 7. Similarly, an explanation and appreciation of the face collation for the subject 1 may be transmitted to the subject 1 via the examiner 7.
[0040]
FIG. 2 is a block diagram illustrating a second concept according to the embodiment of the present invention.
[0041]
This figure shows a case where the subject 1 is inquired about whether or not the certification medium 6 is desired, in addition to the explanation about the face matching shown in FIG. In the figure, the face matching system 3 sends question information for asking whether or not the proof medium 6 indicating that the subject was not a person requiring caution as a result of the face matching (that is, I am not suspicious). Output. When the face collation system 3 receives a response to the question information output from the face collation system 3 to the effect that the subject 1 desires, the certification medium 6 is issued. In addition, you may pass through the inspector 7 like FIG.
[0042]
In the first place, the suspicious individual (the person on the inspection side needs attention) does not bother to say that he is not a suspicious individual. More specifically, the suspicious person either hides it carefully or creates a suspicious atmosphere as it is, and does not bother explaining it. The proof media 6 indicating that "the subject was not a person to be watched as a result of the face comparison (that is, I am not suspicious)" indicates that the suspicious individual dares to take actions that should not be performed. (Humorous, mischievous) ", which is the reason why humor is humorous. The subject 1 who felt the humor, for example, was able to forgive that "it is not very popular to be mushy" or "it is inevitable (face matching)" and so on. The discomfort that has arisen is further healed.
[0043]
FIG. 3 is a block diagram illustrating the principle that the conventional face matching system increases the discomfort of the subject using a psychological model of the subject.
[0044]
In the figure, since the collation with the person requiring attention performed by the face collation system 3 is not clearly seen from the subject 1 side, the subject 1 is suspicious of the unknown collation. Suspicion multiplies, causing great discomfort. Furthermore, even though the result of the collation does not match, that is, even though the collation did not correspond to the person requiring attention, neglect of the explanation for the collation, the great discomfort caused by the feeling of the subject 1 is further increased. There was a problem.
[0045]
Neglect of the description of the face matching by the face matching system 3 is regarded as the subject 1 having no psychological follow-up to the suspicion once. If the procedure is predetermined and the patient 1 is satisfied with the procedure in the mind of the subject 1, this does not cause much problem. However, when the subject 1 voluntarily submits the facial information authentication medium 2, “why should I be suspicious?”, “What is the necessary check (face verification) in the first place? Do not underestimate the existence of such questions that arise naturally. This is because the submission of the facial information authentication medium 2 is favorable to the subject 1.
[0046]
FIG. 4 is a block diagram illustrating the principle of healing the discomfort of the subject using the face matching system according to the embodiment of the present invention, using a psychological model of the subject.
[0047]
This figure corresponds to the concept shown in FIG. In the figure, since the collation with the person requiring attention performed by the face collation system 3 is not clearly seen from the subject 1 side, the subject 1 is suspicious of the unknown collation. Suspicion multiplies, causing great discomfort. However, the face matching system 3 determines that the matching result is inconsistent with the subject 1 who is raising anxiety or suspicion as to "what is used for (your face information)?" You can't answer anything until you get it. It can be said that most subjects to be subjected to face matching are good citizens, and that they are all in their duties to protect these good citizens.
[0048]
Therefore, the essence of the problem is not to cause discomfort in the feelings of the subject 1 by the face matching process. Rather, a psychology that reduces the discomfort once occurring in the subject's feelings by explaining the content of the verification after the face verification process and showing the verification result that did not match, that is, that he was not a person requiring caution. It can be said that it is important to follow the target. Once you have to doubt. However, I have to apologize once because I doubted. If you're convinced that the other person is just going to forgive you, it's a thank you.
[0049]
FIG. 5 is a block diagram illustrating the principle of healing the discomfort of the subject by the face matching system according to the embodiment of the present invention, using a psychological model of the subject.
[0050]
This figure corresponds to the concept shown in FIG. In the figure, following the psychological model shown in FIG. 4, the face matching system 3 inquires the subject 1 about "let's issue a certificate (certification medium 6)?" Although this inquiry itself is merely an inquiry, it is a temporary, but temporary, gap between the subject 1 and the face matching system 3 (examiner 7). But it also increases the effect of humor. This is a psychological follow-up that further reduces the discomfort once generated in the subject 1's feeling of humor. When giving this question to the subject 1, a specific thank-you may be added at this time.
[0051]
FIG. 6 is a block diagram showing specific emotions of the subject and the examiner related to the face matching system according to the embodiment of the present invention.
[0052]
The figure shows a specific emotion that arises between a good subject 1 that is statistically over 90% or more and an inspector 7 who fulfills his duties. The specific scene here assumes an airport. In the figure, as the impression before the two oppose each other, the inspector 7 is burning with a sense of mission, for example, "It is us who protects this country at the water's edge. We do not miss any bad guys." On the other hand, the subject 1 thinks, for example, "I do not know at all what I am doing, I am anxious." This indicates that there is no awareness.
[0053]
In addition, the examiner 7 during the examination (during face information collation) is probably useless (because a person of interest is also in the good subject 1 so as not to give a skit until the doubt is cleared). I work in a state where words are not emitted at all, so to speak. On the other hand, the subject 1 is, for example, "Why are you saying nothing? A scary face""Do not look at the face of a person.""What is the passport (individual equivalent. Subject 1 itself)? There are various thoughts such as "Do you understand properly that you are not a suspicious person?", And the state where there is no unnecessary communication between the two causes the anxiety, suspicion, and discomfort of the subject 1. I will spur.
[0054]
After the examination is completed, an instruction is issued from the face matching system 3 to the subject 1 to explain the examination that has been performed, and the examiner 7 gives an explanation to the subject 1 according to the instruction. For example, a collation explanation of "This time, we checked ..." and an appreciation of, for example, "I thought you were uncomfortable, but thank you for your cooperation" were received via the inspector 7. It is transmitted to the examiner 1. On the other hand, the subject 1 can understand, for example, "I see. Is that so?"
[0055]
Furthermore, according to the instructions output from the face matching system 3, the examiner 7 issues a certificate to the subject 1, for example, "If you wish," I am not ... " How is it? " Subject 1 who heard this asked a strange question, and for example, felt humor, such as "Wow, that's such a stupid". When he thought, "But it might be interesting," he asked, "Would you like me to issue it?" You will want to enjoy that humor. The subject 1 who senses humor from the face matching system 3 as described above has a favorable impression on the examiner 7 who has said so, and eventually with the face matching system 3. Subject 1's impression improved.
[0056]
FIG. 7 is an overall system diagram of the face matching system according to the embodiment of the present invention.
[0057]
This figure corresponds to the concept shown in FIG. In the figure, the face matching system 3 includes an examination terminal 8 that acquires the face information of the subject 1 from the face information authentication medium 2 that the subject 1 or the subject 1 arbitrarily submits. A face matching system control unit 9 is responsible for a matching process after the matching process for matching the acquired face information of the subject 1 with the face information of the person requiring attention acquired from the attention required person information DB 4. The operation of the inspection terminal 8 may be performed by the subject 1 or by the inspector 7. In addition, the attention-required person information DB 4 is provided outside the control unit so that it can be used by the plurality of face matching system control units 9, but may be provided inside the face matching system control unit 9.
[0058]
The face matching system control unit 9 checks the face information of the subject 1 obtained by the examination terminal 8 as the face information obtaining means and the face information of the person requiring attention obtained from the sensitive person information DB 4 on a unit of type requiring attention. Face information collating means 10 and a face information judging means for judging a degree of coincidence as to whether or not the subject 1 matches a person requiring attention based on a result of collation of the face information collated by the face information collating means 10. 11 and, if the acquired subject 1 does not match with the person requiring caution as a result of the determination by the face information determining means 11, the cautionary type of the person requiring caution used for comparison is obtained from the cautionary person information DB 4 The collation explanation information creating means 12 for creating collation explanation information for explaining the type of caution required to match the face information of the subject 1 and the collation explanation information created by the collation explanation information creating means 12 And an information output means 13 that acquires and outputs the determination result from the face information determination unit 11.
[0059]
It is preferable that the face information determination means 11 has a predetermined criterion, and that if the degree of coincidence of the result of comparison by the face information collation means 10 exceeds the criterion, it is determined that the two pieces of face information match. The type of caution is, for example, a criminal, a terrorist, an illegal stayer, a hooligan, etc., which is a subject whose use purpose will be different depending on the purpose of use of the face matching system, and whose purpose of use is a person of caution. .
[0060]
FIG. 8 is an overall system diagram of the face matching system according to the embodiment of the present invention.
[0061]
This figure corresponds to the concept shown in FIG. In the figure, the face collation system 3 further records collation explanation information created by the collation explanation information creating means 12, and a proof medium indicating that the subject 1 is not a person requiring attention with respect to the caution type used for the collation. 6 when the information output means 13 outputs the verification explanation information and the verification result, and outputs question information for inquiring whether the subject 1 desires the verification medium 6. Then, when the subject 1 receives a reply signal regarding a request for obtaining a certification medium indicating that the subject 1 desires to acquire the certification medium 6, the certification medium issuing means 14 issues the certification medium 6.
[0062]
FIG. 9 is a hardware block diagram of the face matching system according to the embodiment of the present invention.
[0063]
In the figure, the examination terminal is specifically a so-called scanner, and reads the face information from the face information authentication medium 2 of the subject submitted by the subject 1 and transmits the face information to the face matching system control unit 9. Carry. Specifically, the medium reading unit 15 includes a light source unit 16, a light source unit 16, and an operation unit 17. When a start button of the operation unit 17 is pressed, light for reading face information is irradiated from the light source unit 16 toward the face information authentication medium 2, The reflected light is read by the medium reading unit 15 to obtain the face information of the subject 1 and transmitted to the face matching system control unit 9 in the form of image data. The function of the operation unit 17 may be included in an HM (human machine) input / output unit 18 provided in the face matching system control unit 9 in some cases.
[0064]
The face matching system control unit 9 is specifically composed of an HM input / output unit 18, a calculation unit 19, a memory unit 20, and a transmission / reception unit 21. The calculation unit 19 is based on a processing program stored in the memory unit 20 in advance. The face information is cut out from the image data of the face information of one subject transmitted from the inspection terminal 8, and the face information of the person requiring attention and the features included in the face information acquired by the transmitting / receiving unit 21 from the person of interest information DB 4. By comparing the amounts, it is determined whether or not the degree of matching exceeds a predetermined reference. Information output from the face matching system 3 to the inspector 7, such as the matching result, is output via the output unit of the HM input / output unit 18, and a response regarding the issuance of the certification medium 6 from the subject 1 is checked 7 through the input unit of the input / output unit 18. Note that the cautionary person information DB 4 may be provided inside the face matching system control unit 9. The issuing unit 22 is a so-called printer that issues the certification medium 6, and issues the certification medium 6 when the subject 1 receives answer information indicating that the subject 1 desires the certification medium 6 from the HM input / output unit 18. I do. When the certification medium 6 is issued, covering the printed surface or the entire certification medium 6 with a printed surface protection sheet such as a laminated film helps to prevent the certification medium 6 from being forged. Processing such as covering the certification medium 6 with a printing surface protection sheet may be automatically processed by the issuing unit 22, or if there is an inspector 7, the inspector 7 is instructed to perform the processing. It may be performed.
[0065]
FIG. 10 is a block diagram illustrating a specific example of the database structure of the personal identification information DB in the embodiment of the present invention.
[0066]
In the figure, the type information is, for example, a criminal, a terrorist, an illegal stayer, a hooligan, etc., which will differ depending on the purpose of use of the face matching system, and the purpose of use is an object requiring attention, Each group stores personal information. Depending on personal information, it may belong to a plurality of types of persons requiring attention. Among these personal information, in addition to at least the face information, information effective for identifying the individual such as fingerprint information and voiceprint information, and history information such as criminal record, arrest record and the like are also recorded. Good.
[0067]
FIG. 11 is a functional block diagram of the face matching system according to the embodiment of the present invention.
[0068]
This figure corresponds to the concept shown in FIG. In the figure, the face matching system 3 has a function of acquiring the face information of one subject from the face information authentication medium 2 submitted by the subject 1, and has read out the acquired face information and the person-of-attention information DB4. A function that matches the face information of the person requiring attention, a function that determines whether or not the person of interest needs to be matched based on the result of the matching, and a function that needs to be used for face matching when the result of the matching does not match A function to acquire the type information of the person from the person-of-interest information DB4, a function to create collation explanation information describing the type collated based on the acquired type information of the person to be cautious, and a function to output the collation result Have. The function of outputting the collation result is a function of outputting the collation result together with the collation explanation information when the judgment result does not match, and instructing the examiner 7 to take an appropriate measure when the judgment result matches. Output to If the judgment result is inconsistent, a word of appreciation is read from the appreciation (information) DB 5 and added to the collation explanation information by the function of creating collation explanation information, and the collation result is output.

This is an example of an output screen directed to the inspector 7 when it is determined that the examiner 1 does not match the caution person and the subject 1 is not a caution person. In the same figure, the display of "not similar to any person requiring attention" in the output screen is an explanation of the inspection result (collation result), and similarly, "explains the reason for returning the ID card and performing face collation.""Please" is the explanation of the inspection reason (verification explanation information). Similarly, "If you need a certificate, please press the following button" is there.
[0081]
FIG. 18 is a diagram illustrating a specific example (an example of an output screen) of a screen output from the face matching system according to the embodiment of the present invention.
[0082]
7 is an example of an output screen output by the HM input / output unit 18 included in the face matching system control unit 9 by the information output unit 13 illustrated in FIGS. 7 and 8. The inspector 7 does not operate the face matching system 3. In a face matching system in which the subject 1 operates alone, the subject 1 does not match the person requiring attention in the flowchart shown in FIG. 13 or FIG. 7 is an example of an output screen directed to a subject 1 when it is determined that the subject is not the subject. In the same figure, the indication "This time, a hooligan was checked" in the output screen is an explanation of the inspection reason (verification explanation information), and similarly, "As a result, it did not match any hooligan" Is a description of the inspection result (verification result). Similarly, the display "If you need a certificate based on this verification result, please press the following button" is the confirmation of whether the certification medium is required (question information). is there. In addition, as shown in the example of the figure, a word expressing appreciation may be displayed on the output screen, "I was disturbed, but thank you for your cooperation."
[0083]
FIG. 19 is a diagram showing a specific example of the certification medium in the embodiment of the present invention.
[0084]
In the same figure, the humor that considers the feelings of human beings is described in the face verification certificate (certification medium 6) as "I am not a hooligan" and "I will prove that you are not a hooligan". Can be done. Also, by giving the face area cutout images shown in FIGS. 17 and 18 to this certificate, the subject 1 can easily understand the third party who shows this certificate. Further, this certificate has an expiration date of, for example, six months, and is preferably described. Finally, by saying "Thank you for your cooperation" as an appreciation and, for example, "XX police station" as an issuing organization that can be affirmed, the effect as the proof medium 6 is enhanced.
[0085]
FIG. 20 is a diagram showing a specific example of the certification medium in a case different from that of FIG.
[0086]
FIG. 19 shows a specific example in which the description contents are made as simple as possible as compared with FIG. In the figure, "I'm not a Hooligans!" And "I am not a hooligan" in the proof medium 6 correspond to humor. Similarly, "Thank you for your cooperation, though it was annoying."
[0087]
For those who wonder why such a proof medium 6 is necessary for the face matching system 3, it is relatively easy to understand, for example, by giving the following explanation. "Of course, many people, including you, don't need to be suspicious, but you have to be suspicious once to distinguish them from the few who are suspicious. However, if you are suspicious, only unpleasant feelings will remain in you, so the system will explain the result of the verification and the reason for it. I'm skeptical, so I'll explain it first: this is the minimum necessary sincerity and gratitude, and for example, in the case of a Hooligan collation, "I'm not a Hooligan" It is also possible to issue a written collation proof medium with your photo, of course, this is only humor, but we value this humor I want to come. "
[0088]
【The invention's effect】
According to the present invention described above, since the collation with the person requiring attention performed by the face collation system is not clearly visible from the subject side, the subject is suspicious of the unknown collation. Although suspicion grows and major discomfort occurs once, the subject can be explained by explaining the verification contents after the face verification process and indicating that the verification result was inconsistent, that is, that he was not a person requiring caution. Psychological follow-up to reduce the discomfort once occurring in the feelings of the person.
[0089]
Furthermore, by making an inquiry such as "Let's issue a certificate (certification medium)" from the face matching system to the subject, the inquiry itself is humor, so the subject who feels humor can It can be a psychological follow-up in which the discomfort once generated in one's own feeling is further reduced. This is because the gap in inquiring with questions containing humor just after the subject and the examiner (the face matching system) have a tension has further increased the effect of humor.
[0090]
From another point of view, if accountability is not fulfilled, for example, if the reason for verification is not explained at all, the examiner will have a sense of resistance to power and a sense of exclusion that will make the inspector feel that way. For example, by explaining the reason, "Actually ..." and showing the attitude of "I doubted you, even though it was my job. (I'm sorry)." It is also expected that the subject's sense of exclusion will be relaxed and the subject will feel closer to the test side.
