Description

  The present invention relates to a system for performing face authentication of a visitor such as an event venue.

  Conventionally, as a method of authenticating visitors at event venues where only those who have applied in advance can enter, the faces of the visitors are photographed and compared with the face images of the visitors registered in the authentication server in advance There is a system for performing face authentication by performing (for example, Patent Document 1).

JP 2003-187352 A

  By the way, when authenticating a visitor in an event venue etc., the following methods can be considered. That is, a ticket is sent to a visitor in advance, and the visitor carries the ticket with him. Then, the visitor reads identification information such as a QR code (registered trademark) printed on the ticket into a reader of an accepting device (authentication device) installed at the entrance of the venue. Then, the face image of the visitor registered in advance in the authentication server in association with the read identification information is compared with the face image of the visitor photographed at the event venue or the like and collated. .

  However, in the conventional face authentication system, in many cases, a reader such as a QR code of a reception device and a camera device that captures the face of a visitor are installed separately. Therefore, for example, a legitimate right holder who has the entry qualification approaches the camera so that his / her face is photographed by the camera, and then a person who tries to enter illegally impersonates the person who has the right title. It was possible to make unauthorized entry by reading QR codes, etc. As a result, there was a problem that a person who was not originally qualified for admission would enter illegally.

  In view of the problems as described above, an object of the present invention is to provide a face authentication system capable of more accurately performing face authentication processing of a visitor to a specific area where only a person having admission qualification can enter. To do.

  In order to solve the above-described problem, an aspect of the present invention is an authentication device for performing face authentication to determine whether a person to be authenticated is a legitimate authority who should be permitted to enter a specific area.

(Configuration of face recognition system)
FIG. 1 is a diagram illustrating an example of the configuration of the face authentication system according to the present embodiment. The face authentication system 1 according to the present embodiment is a system for performing face authentication at an event venue or the like where only a visitor having a legitimate title of entry can enter. Specifically, the person having a legitimate title (legitimate title holder) may be, for example, a person who has obtained a regular ticket or a person who has received a regular ticket from a person who has obtained a regular ticket. Note that the ticket may be issued on a paper basis, or may be a digital ticket distributed from the website for application to the applicant's mobile terminal through the network. In this embodiment, the case of a digital ticket will be described as an example.

  The face authentication system 1 illustrated in FIG. 1 includes an authentication device 10, a mobile terminal 20 carried by a visitor, and an authentication server 30 that executes a visitor authentication process.

  In the face authentication system 1 according to the present embodiment, the face authentication of the visitor is performed, but before that, the visitor performs a procedure for acquiring a ticket properly by purchasing a digital ticket in advance. It is a premise. For example, it is assumed that the purchase procedure of digital tickets is mainly performed online, but visitors purchase in advance by entering their face images and personal data such as name, address, and telephone number at the purchase site. Perform the procedure. When the purchase procedure is completed normally, the visitor obtains a digital ticket issued from the ticket issuer by a method such as download and stores it in the portable terminal 20. Then, the portable terminal 20 is carried to the event venue, and the entrance procedure is performed by displaying the digital ticket and causing the authentication device 10 to read it.

  Hereinafter, the configuration of each apparatus will be described.

(Configuration of mobile device)
The mobile terminal 20 is a mobile terminal possessed by an attendant, and includes a terminal storage unit 202 and a display unit 204.

  The terminal storage unit 202 stores a digital ticket obtained by purchasing in advance. Here, the digital ticket used in the face authentication system according to the present embodiment includes a face image of the visitor and identification information for uniquely identifying the visitor (or ticket). The identification information may take any form. For example, it may be a character string, a one-dimensional code such as a barcode, a two-dimensional code such as a QR code, or the like. In the present embodiment, a case of a QR code will be described as an example.

  The display unit 204 displays the digital ticket stored in the terminal storage unit 202. The visitor displays the digital ticket on the display unit 204 and causes the identification information acquisition unit 102 of the authentication device 10 described later to read a QR code (identification information).

(Configuration of authentication device)
The authentication device 10 is a device that is assumed to be installed in the vicinity of an entrance of a specific area such as an event venue or an airport where only those who have the right to enter can enter. This is a device for performing face authentication in order to determine whether or not a venue visitor or the like) is a legitimate person who should be allowed to enter a specific area. The authentication device 10 includes an identification information acquisition unit 102, a first imaging unit 104, a second imaging unit 106, an output unit 108, and a ticket issuing unit 110.

  The identification information acquisition unit 102 acquires identification information for identifying the person to be authenticated. Specifically, the identification information acquisition unit 102 is, for example, a QR code reader or the like. For example, a visitor displays a digital ticket including a QR code (identification information) on the display unit 204 of the mobile terminal 20 to display a QR code reader (identification). It is acquired by holding it over the information acquisition unit 102).

  The first photographing unit 104 photographs the authentication target person at substantially the same timing as the identification information acquisition part 102 acquires the identification information provided by the authentication target person. Specifically, for example, the first photographing unit 104 is configured to authenticate the person to be authenticated at substantially the same timing as when the person to be authenticated holds a digital ticket including a QR code (identification information) over a QR code reader (identification information acquisition unit 102). Shoot the face. “Substantially the same timing” means that it is sufficient if the timing is almost the same, even if not exactly the same. By photographing the face of the person to be authenticated at such timing, the attendees are switched between the time when the identification information acquisition unit 102 obtains the identification information and the time when the face of the person to be authenticated is photographed. It is possible to avoid a situation where an unqualified person enters illegally.

  The second imaging unit 106 images the authentication target person at a timing that is substantially the same as or different from the timing at which the identification information acquisition unit 102 acquires the identification information provided by the authentication target person. Specifically, for example, the second photographing unit 106 is configured to be substantially the same, before, after, or substantially the same as the person to be authenticated holding a digital ticket including a QR code (identification information) over a QR code reader (identification information acquisition unit 102). Photograph the face of the person to be authenticated. For example, the second imaging unit 106 determines the authentication target person at the timing of approaching the authentication apparatus 10 and walking (the face is almost straight) before the authentication target person causes the QR code reader to read the QR code. Take a picture of your face. Alternatively, for example, the face of the person to be authenticated is photographed at a timing when the person to be authenticated walks toward the entrance after the QR code is read by the QR code reader (the face is almost straight).

  The output unit 108 includes authentication information including the identification information acquired by the identification information acquisition unit 102 and a first authentication image that is an image including the face portion of the person to be authenticated captured by the first imaging unit 104. Is output. Further, the output unit 108 may further output a second authentication image that is an image including the face portion of the person to be authenticated photographed by the second photographing unit 106. For example, the output unit 108 may output the captured image captured by the first imaging unit 104 and the second imaging unit 106 as it is, or may output a part of the captured image including the face portion of the person to be authenticated or the face portion. May be cut out and output. Further, the output unit 108 may output an image obtained by performing some processing on the captured image.

  The ticket issuing unit 110 issues another ticket related to the digital ticket when data indicating that the verification is successful is output as a verification result in the verification unit 304 from the result output unit 306 of the authentication server 30 described later. It has a function. For example, it may be possible to issue a seat ticket at an event venue. The ticket issuing unit 110 may print out a seat ticket or the like, or may output a command for issuing a ticket to an external ticket issuing apparatus together with necessary information such as a seat number. In addition to issuing tickets on a paper basis, for example, a seat number may be transmitted to the mobile terminal 10 of the user. When printing out a seat ticket or the like, at least the printing device needs to be installed near the entrance of the venue, but the ticket issuing unit 110 itself may be a device different from the authentication device 10.

(Authentication server)
The authentication server 30 is a server installed in a remote place different from the authentication device 10 via a network, for example. Alternatively, the authentication device 10 may be installed separately or integrally with the authentication device 10. The authentication server 30 includes a visitor information storage unit 302, a verification unit 304, and a result output unit 306.

  The visitor information storage unit 302 stores the identification information and the face image data of the legitimate right person who should be permitted to enter in association with each other. FIG. 2 shows an example of data stored in the visitor information storage unit 302. In FIG. 2, the identification information, the name of the visitor (applicant), the address, the telephone number, and the file name of the face image data are associated in a database format. Also, the face image data having the file name shown in the “face image data” field in FIG. 2 is also stored in the visitor information storage unit 302. When a visitor inputs such information (including his / her face image) online at the time of application for entry, the information is stored in the visitor information storage unit 302 in a format as shown in FIG.

  Here, the rightful owner is a person who has made an application for admission (paid or free of charge) and is permitted to enter. However, for example, there are cases where a person who obtains a ticket for an event or the like and a person who actually goes to the event or the like are different. However, if the ticket acquisition is performed by a legitimate means or the ticket is transferred by a legitimate means, the person who has obtained the ticket is the “right party”. In such a case, after the ticket is obtained, it is possible to notify the ticket issuer of the face image data of the new visitor and the address of the visitor by changing the visitor. It may be. The ticket issuer rewrites the contents of the visitor information storage unit 302 when an entry change procedure or the like is performed.

  The collation unit 304 obtains the face image data of the legitimate right original person associated with the identification information output from the authentication device 10 from the visitor information storage part 302, the face image data of the legitimate right original person, and the authentication device 10 is collated with at least the first authentication image output from 10. Further, the collation unit may collate the acquired face image data of the original right holder and the second authentication image output from the authentication device 10.

  Specifically, for example, the collation unit 304 searches the visitor information storage unit 302 using the identification information output from the authentication device 10 as a key, and extracts the face image data of the visitor associated with the identification information. . Then, the extracted face image data is collated with the first authentication image (and the second authentication image) output from the authentication device 10. In addition, collation of these image data can be performed using a prior art. In addition, the determination of the coincidence or disagreement between the two may be, for example, that a certain threshold value is provided, and a matching result “match” is obtained when the coincidence rate of both is equal to or greater than the threshold value. As described above, the first authentication image and the second authentication image are based on the captured images captured by the first capturing unit 104 and the second capturing unit 106, but are captured at different positions. Therefore, for example, even when face authentication using the first authentication image is difficult because the quality of the first authentication image is low, face authentication can be executed with the second authentication image. . Further, the face authentication may be performed with higher accuracy by collating both the first authentication image and the second authentication image with the face image data in the visitor information storage unit 302.

  The result output unit 306 outputs the collation result in the collation unit 304. If the collation result in the collation unit 304 is unsuccessful (the faces do not match), for example, result data indicating that fact is transmitted to the authentication device 10. Upon receiving the unsuccessful result data, the authentication device 10 may display a message indicating that the face images do not match, for example, on a display (not shown). When the authentication server 30 is installed at the entrance of an event venue or the like, the verification result may be displayed on a display (not shown) provided in the authentication server 30. Further, for example, the collation result may be displayed on a computer for an attendant at a venue entrance (including a mobile terminal such as a smartphone). Then, if the result of the verification is unsuccessful, the clerk displays the face image of the legitimate right person stored in the authentication server 30 on the clerk's computer, and displays the face of the person to be authenticated who actually came. It may be possible to make a visual comparison. At this time, for example, the face image data of the legitimate right holder stored in the authentication server 30 together with the collation result may be transmitted to the attendant computer, or the authentication server 30 may be transmitted to the attendant computer in advance. A copy of the face image data of the legitimate right owner stored in the may be stored.

  As described above, the authentication device 10 and the authentication server 30 may be configured integrally (for example, as one device). In this case, the authentication server 30 may be provided with the ticket issuing unit 110 (the same function as the above) of the authentication device 10 described above.

(Hardware configuration)
Each device described above can be realized by a hardware configuration similar to that of a general computer device. FIG. 3 is a diagram illustrating an example of a hardware configuration of each apparatus. As an example, the computer apparatus 4 shown in FIG. 3 includes a processor 41, a RAM 42, a ROM 43, a built-in hard disk device 44, an external hard disk device, a CD, a DVD, a USB memory, a memory stick, an SD card, and other removable devices. A memory 45, a communication interface 46 that communicates with other computer devices, and an input / output user interface 47 (display, touch panel, keyboard, mouse, speaker, lamp, etc.) for the user to exchange data are provided. In addition to these components, the authentication device 10 includes two cameras (first photographing unit 104 and second photographing unit 106) and a QR code reader (identification information obtaining unit 102). The function of each component of each device according to the present embodiment can be realized by, for example, the processor 41 reading a program stored in advance in the hard disk device 44, the ROM 43, the removable memory 45, etc. into a memory such as the RAM 42 and executing it. It is. Note that the hardware configuration shown in FIG. 4 is merely an example, and the present invention is not limited to this.

(Processing sequence)
FIG. 4 is a sequence diagram illustrating an example of processing in the face authentication system according to the present embodiment.

  First, for example, when the authentication apparatus 10 (or another apparatus) detects that the person to be authenticated is approaching within a predetermined range in the shooting direction of the second shooting unit 106 of the authentication apparatus 10, the second shooting is performed. Unit 106 photographs the person to be authenticated (step S100).

  Thereafter, the display unit 204 of the mobile terminal 20 displays a digital ticket including a QR code (identification information) according to the operation of the person to be authenticated (step S102). Then, when the user holds the display unit 204 of the portable terminal 20 on which the digital ticket is displayed over the QR code reader (identification information acquisition unit 102) of the authentication device 10 (step S104), the QR code reader reads the QR code ( Read identification information). At substantially the same time, the first photographing unit 104 photographs the person to be authenticated (step S106). If the QR code is not read normally (step S108: No), a message indicating that the reading is NG is output (step S110). The output may be performed by various methods, for example, displaying a message on the display of the authentication device 10, outputting by voice, or indicating by lighting / flashing of a lamp. Then, the QR code is read again through steps S104 and S106.

  If the QR code is normally read (step S108: Yes), the first authentication image, the second authentication image, and the identification information acquired from the QR code are output to the authentication server 30 ( Step S112).

  When the authentication server 30 acquires the first authentication image and the QR code from the authentication device 10, the authentication target person is referred to with reference to a database stored in the visitor information storage unit 302 using the acquired identification information as a key. Search for face image data. The extracted face image data is collated with the first authentication image (and the second authentication image) acquired from the authentication device 10 (step S114). At this time, the first authentication image may be collated first, and if the authentication is unsuccessful, the second authentication image may be collated.

  The authentication server 30 transmits the verification result to the authentication device 10 (step S116). In the authentication device 10, when the result of the verification is unsuccessful (step S118: No), for example, a warning sound is sounded, a light blinks, etc., and the nearby staff is notified. (Step S120). Moreover, the collation result may be transmitted to a portable terminal or the like carried by the attendant. If the result of the verification is a success (step S118: Yes), a normal termination process (for example, a staff member in the vicinity of the authentication device 10 that performs the ticket issuing process in the ticket issuing unit 110 can confirm the verification success). The lamp is turned on, etc. (or nothing need be executed) and the process is terminated (step S122) (the person to be authenticated can enter the event venue or the like).

  In the sequence diagram of FIG. 4, the second photographing unit 106 photographs the person to be authenticated in step S100. However, in the photographing by the second photographing unit 106, the QR code is normally read in step S108. After being performed (step S108: Yes), it may be executed.

(Authentication device structure)
As described above, in the authentication device 10 according to the present embodiment, at least the identification information acquisition unit 102 and the first imaging unit 104 are arranged close to each other, and the identification information acquisition unit 102 acquires the identification information from a digital ticket or the like. By making the timing and the timing of photographing the face of the person to be authenticated almost simultaneous, another person tries to improperly enter on behalf of the person who has the right to enter during these processes. Can be avoided.

  Furthermore, the inventor of the present invention examined the arrangement for the first photographing unit 104 and the second photographing unit 106 to acquire a higher quality face image as follows.

  FIG. 5 is a diagram illustrating an example of an external view of the authentication apparatus according to the present embodiment. The authentication device 10 according to the present embodiment includes a QR code reader 602 (602a, 602b: corresponding to the identification information acquisition unit 102), a first camera 604 (604a, 604b: corresponding to the first photographing unit 104), and a second camera. 606 (606a, 606b: corresponding to the second imaging unit 106).

  The authentication device 10 of the present embodiment is assumed to be installed at an entrance of a specific area such as an event venue. When a visitor tries to enter a specific area, he / she first walks toward the authentication device 10 installed at the entrance to the specific area. At this time, for example, when the authentication device 10 (or another device) detects that the person to be authenticated has approached within a predetermined range in the shooting direction of the second camera 606 of the authentication device 10, the second camera Reference numeral 606 photographs a person to be authenticated.

  After that, the person to be authenticated reads the ticket with the QR code (identification information) of the digital ticket sent in advance over the QR code reader 602, and at the same time, the first camera 604 receives the visitor. Take a picture of the face. After that, the visitor walks toward the entrance to the specific area, and at this time, the visitor passes the side of the authentication device 10 along the mounting table 610 from the first camera 604 toward the second camera 606. The authentication apparatus 10 is installed so as to be in the form of going. Note that the second camera 606 may be configured to photograph the face portion of the authentication target person at substantially the same timing as the authentication target person holds the QR code over the QR code reader 602, for example. The face part of the person to be authenticated may be photographed at a timing when the person passes the side of the authentication device 10 after the QR code is read by the QR code reader 602.

  The authentication device 10 illustrated in FIG. 5 includes two QR code readers 602, two first cameras 604, and two second cameras 606. This is because the position of the face when the ticket is held over the QR code reader 602 changes depending on whether the visitor is right-handed or left-handed. 602b is assumed to be used by left-handed visitors. However, the present invention is not limited to this, and a left-handed visitor may use the QR code reader 602a, and a right-handed visitor may use the QR code reader 602b, or the QR code reader 602, the first camera. One 604 and one second camera 606 may be provided.

  As described above, the authentication device 10 according to the present embodiment allows the first camera 604 to photograph the face portion of the visitor at substantially the same timing as when the visitor causes the QR code reader 602 to read the QR code. The face of the visitor who has the identification information read by the QR code reader 602 can be reliably photographed.

  Here, the inventor of the present invention repeats trials in order to photograph the face of the visitor with higher quality at the timing as described above, and the QR code reader 602, the first camera 604, and the second camera 606. Was determined. Details will be described below.

First, FIG. 6 is a diagram illustrating a positional relationship between each unit of the authentication device 10 and a visitor (authentication target person). The visitor 50 displays the digital ticket with the QR code on the portable terminal 20 and holds it over the QR code reader 602 of the authentication device 10. At this time, it is assumed that the attendee's line of sight is usually facing the digital ticket (QR code reader 602), and the visitor's face 54 is facing downward. The first camera 604 is installed at an angle such that the face 54 of the visitor facing downward is photographed while looking up from below. Given this situation, the following relation holds:
Height at which the first camera 604 is installed ≒ Height at which the QR code reader 602 is installed + length of a visitor's hand + length from a visitor's shoulder to eyes

  The inventors of the present invention repeated trials under the above conditions. Table 1 is a table showing data regarding each trial.

  Here, in Table 1, each value of the QR code reader 602, the first camera 604, and the second camera 606 means the height from the ground. Based on the results shown in Table 1, the appropriate positional relationship among the QR code reader 602, the first camera 604, and the second camera 606 was found as follows.

  In the above table, the “azimuth angle” of the first camera 604 and the second camera 606 indicates how much the azimuth angle is toward the passage with respect to the direction from the front to the rear of the authentication device 10. Moreover, since the elevation angle and azimuth angle of the first camera 604 and the second camera 606 are determined by the direction in which the face portion of the visitor can be photographed, they can be determined by common sense angles. The QR code reader 602 is installed at a position of approximately 0 to 100 mm from the front surface of the mounting table. FIGS. 7A and 7B are examples of a plan view and a side view of the authentication device 10 shown in FIG. 5, respectively, and illustrate the dimensions shown in the above table.

  Note that, as described above, the face authentication system according to the present embodiment mainly includes unauthorized entry by the first camera 604 photographing the person to be authenticated almost simultaneously with the QR code reader 602 reading the QR code. Is to prevent. Therefore, it is not influenced by conditions such as the performance and model of the first camera 604 and the second camera 606.

  According to the authentication device and the face authentication system using the same according to the present embodiment, it is possible to prevent an act of illegally entering in the face authentication process of a visitor to a specific area where only a person having admission qualification can enter. it can. In addition, since the visitors themselves perform self-authentication and face authentication without stopping, a more speedy face authentication process can be realized.

  Up to this point, one embodiment of the present invention has been described. However, the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention may be implemented in various forms within the scope of the technical idea.

  In addition, the scope of the present invention is not limited to the illustrated and described exemplary embodiments, and includes all embodiments that provide the same effects as those intended by the present invention. Further, the scope of the invention is not limited to the combinations of features of the invention defined by the claims, but may be defined by any desired combination of particular features among all the disclosed features. .
