[0018] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals, and duplicated explanations will be omitted.

[0019] <<1. Overview of the information processing system>> When using a service provided by a government or private company, a user may submit a photo ID to prove the user's identity in addition to application data. A verifier from the government or private company must then verify the various data submitted. For example, the verifier checks the details of the application data and checks the image data of the photo ID to see if there is anything unusual about the various printed information included in the photo ID and whether the photo has been tampered with.

[0020] When verifying such non-face-to-face photo identification documents, for example when the document is so elaborately crafted that a photo of another person is meticulously pasted onto it, it can become difficult for the verifyer to determine whether the photo is that of the owner of the identification document.

[0021] Therefore, the information processing system according to this embodiment determines the validity of a facial photograph being the facial photograph of the owner based on characteristic information relating to the outer frame of the facial photograph included in a photo-attached identification document.

[0022] Hereinafter, a technology for determining whether a face photo included in a photo-attached identification document is a face photo of the owner by the information processing system according to the present embodiment will be described in order. First, an overview of the information processing system will be described with reference to FIG.

[0023] 1 is an explanatory diagram for explaining an example of an information processing system according to the present embodiment. The information processing system according to the present embodiment includes a network 1, an examination terminal 10, an examination system 20, and a server 30.

[0024] (Network 1) The network 1 connects the examination terminal 10 and the examination system 20, and the examination system 20 and the server 30. For example, the network 1 includes a wide area Internet line or a dedicated line using a communication cable such as an Ethernet cable for communication conforming to standards such as IEEE.

[0025] (Examination terminal 10) The examination terminal 10 is an information processing terminal for verifying an identity document. For example, the examination terminal 10 may be a PC (Personal Computer) or a smartphone. In the following description, an example in which the examination terminal 10 is a PC as shown in FIG. 1 will be mainly described.

[0026] (Examination System 20) The screening system 20 holds the application data of the user and the image data of the personal identification document. The screening system 20 according to the present embodiment may be, for example, a PC or a server.

[0027] For example, a terminal of a user who uses a certain service transmits application data and image data of a photo ID document to the screening system 20. Then, when a verifyer selects the application of the user during the screening, the screening system 20 transmits the application data and image data of the photo ID document to the server 30. In the following description, the image data of the photo ID document may be simply referred to as a photo ID document.

[0028] (Server 30) The server 30 is an example of an information processing device, and determines the validity of the facial photograph included in the photo identification document being the facial photograph of the owner, based on characteristic information related to the outer frame of the facial photograph included in the photo identification document.

[0029] An example of the information processing system according to the present embodiment has been described above. Next, an example of the functional configuration of the examination terminal 10 and the examination system 20 according to the present embodiment will be described with reference to FIG.

[0030] <<2. Example of Functional Configuration of Examination Terminal 10 and Examination System 20>> 2 is an explanatory diagram for explaining an example of a functional configuration of the examination terminal 10 and the examination system 20 according to the present embodiment. First, an example of a functional configuration of the examination terminal 10 according to the present embodiment will be described.

[0031] The examination terminal 10 according to this embodiment includes an operation unit 11, a display unit 13, a control unit 15, and a communication unit 17, as shown in FIG.

[0032] The operation unit 11 accepts an operation input from a checker. For example, the operation unit 11 allows the checker to select an object to be examined.

[0033] The operation unit 11 may be, for example, various input devices such as a mouse and a keyboard.

[0034] The display unit 13 displays the application data and the personal identification document. The display unit 13 also displays the validity, which is the face photo of the owner received from the screening system 20.

[0035] The display unit 13 may be, for example, a CRT (Cathode Ray Tube) display device, a liquid crystal display (LCD) device, or an OLED (Organic Light Emitting Diode) device.

[0036] The control unit 15 controls the overall operation of the examination terminal 10. For example, the control unit 15 controls various communications by the communication unit 17.

[0037] The communication unit 17 performs various communications with the screening system 20. For example, the communication unit 17 transmits to the screening system 20 information related to the screening target selected by the user.

[0038] In addition, the communication unit 17 receives information from the screening system 20 regarding the validity of the facial photograph included in the photo-attached identification document determined by the server 30 as being the facial photograph of the owner.

[0039] The above is a description of an example of the functional configuration of the examination terminal 10 according to the present embodiment. Next, a description will be given of an example of the functional configuration of the examination system 20 according to the present embodiment.

[0040] The examination system 20 according to this embodiment includes a database unit 21, a control unit 23, and a communication unit 25, as shown in FIG.

[0041] The database unit 21 holds various types of customer information such as application data and image data of a photo ID document corresponding to the application data.

[0042] The control unit 23 controls the overall operation of the examination system 20. For example, the control unit 23 controls various communications by the communication unit 25.

[0043] The communication unit 25 performs various communications with the examination terminal 10. The communication unit 25 also performs various communications with the server 30.

[0044] For example, the communication unit 25 receives information about the subject of the screening from the screening terminal 10, and transmits to the server 30 application data and a photo ID corresponding to the subject of the screening.

[0045] In addition, the communication unit 25 receives the judgment result of the examination target from the server 30 and transmits the judgment result to the examination terminal 10.

[0046] An example of the functional configuration of the examination system 20 according to this embodiment has been described above. Next, an example of the functional configuration of the server 30 according to this embodiment will be described with reference to FIG.

[0047] <<3. Example of functional configuration of server 30>> 3 is an explanatory diagram for explaining an example of a functional configuration of the server 30 according to the present embodiment. As shown in FIG. 3, the server 30 according to the present embodiment includes a database unit 31, a communication unit 33, and a control unit 35.

[0048] The database unit 31 holds master data of a certain standard identification document with a face photograph.

[0049] The communication unit 33 performs various communications with the screening system 20. For example, the communication unit 33 receives image data of the photo identification document to be screened from the screening system 20. The communication unit 33 also transmits to the screening system 20 a determination result indicating the validity of the face photo on the photo identification document being the face photo of the owner.

[0050] The control unit 35 controls the overall operation of the server 30. As shown in FIG.

[0051] The recognition unit 351 recognizes various printed information and the facial photograph contained in the photo identification document received from the screening system 20.

[0052] In addition, the recognition unit 351 recognizes the outer frame of the face photograph included in the photo-attached identification document received from the screening system 20.

[0053] For example, the recognition unit 351 may recognize, as the outer frame of the face photo, straight lines that are included in a predetermined range of the face photo identification document and at least one of the length and angle satisfies a predetermined condition. This allows the recognition unit 351 to recognize the outer frame of the face photo with higher accuracy without recognizing lines of the clothes, face, etc. included in the face photo as the outer frame of the face photo.

[0054] The recognition unit 351 may also convert the number of pixels of the identification document with a face photo into a predetermined number, thereby enabling the recognition unit 351 to recognize various types of printed information and face photos with higher accuracy.

[0055] The recognition unit 351 may also recognize feature information related to the outer frame of the facial photograph included in the photograph-attached identification document received from the screening system 20. Specific examples of feature information related to the outer frame of the facial photograph will be described later.

[0056] The learning unit 353 generates learning data by a machine learning technique using a combination of print information on a personal identification document with a face photo and feature information on the outer frame of the face photo as training data.

[0057] The estimator 355 is an example of an estimation unit, and inputs a user's identification document with a facial photograph to estimate feature information related to the outer frame of the facial photograph. The function of the estimator 355 is obtained by the learning data generated by the learning unit 353.

[0058] For example, the estimator 355 estimates standard feature information relating to the outer frame of the face photograph on the user's photo identification document based on the print information included in the user's photo identification document.

[0059] The determination unit 357 determines whether the face photo included in the photo identification document is the face photo of the owner based on feature information related to the outer frame of the face photo included in the photo identification document. A specific example of the determination of validity will be described later.

[0060] An example of the functional configuration of the server 30 according to this embodiment has been described above. Next, a specific example of the determination according to this embodiment will be described with reference to FIG.

[0061] <<4. Specific examples of validity judgment>> 4 is an explanatory diagram for explaining a specific example of a process for determining the validity of the owner's face photo from a driver's license. Note that the driver's license C shown in FIG. 4 is an example of an identification document with a face photo.

[0062] 4, the driver's license C includes various printed information and a facial photograph. The various printed information includes, for example, the issue date W1 and the issuer W2.

[0063] First, the recognition unit 351 recognizes the print information of the driver's license C and the facial photograph from the image data of the driver's license.

[0064] The recognition unit 351 also recognizes the outer frame of the facial photograph. More specifically, the recognition unit 351 recognizes a straight line connecting points P1 and P2, a straight line connecting points P2 and P3, a straight line connecting points P3 and P4, and a straight line connecting points P4 and P1, which are on the outer frame of the facial photograph.

[0065] Then, the recognition unit 351 recognizes feature information regarding each recognized line. Note that the feature information of each line includes various information such as the position, length, angle, or width of each line.

[0066] For example, the recognition unit 351 may recognize the position of each straight line using the distance from predetermined printed information included in the driver's license C to each vertex on the outer frame of the facial photograph. More specifically, the recognition unit 351 may calculate the distance from the printed information W3, "Driver's License," to each of points P1, P2, P3, and P4 on the outer frame of the facial photograph, and recognize the position of each straight line using the calculated distances.

[0067] Next, the estimator 355 estimates standard feature information related to the outer frame of the facial photograph based on the print information recognized by the recognition unit 351. The standard feature information includes various information such as the position, length, angle, or width of a reference straight line.

[0068] For example, the estimator 355 estimates standard feature information regarding the outer frame of a facial photograph based on the issue date w1 and issuer w2 included in the driver's license C.

[0069] Then, the judgment unit 357 compares the feature information regarding the outer frame of the facial photograph on the driver's license C with the standard feature information, and based on the result of the comparison, judges the validity of the facial photograph included in the driver's license C being a facial photograph of the owner of the driver's license C.

[0070] For example, the determination unit 357 may perform a similarity evaluation between feature information of the outer frame of the face photograph on the driver's license C and the standard feature information, and determine the result of the similarity evaluation as the validity that the face photograph is the face photograph of the owner.

[0071] A specific example of the process for determining the validity of the face photo of the owner from the driver's license according to this embodiment has been described above. Next, the operation of the information processing system according to this embodiment will be described in sequence with reference to Figs. 5 and 6.

[0072] <<5. Example of Operation Processing of Information Processing System According to the Present Embodiment>> 5 is an explanatory diagram for explaining an example of the operation process of the information processing system according to the present embodiment. First, in the examination terminal 10, the unexamined data is inquired by the verifying person, and an examination target is selected (S101).

[0073] Then, the screening system 20 transmits the personal identification document selected by the verifying person as the subject of screening to the server 30 (S105).

[0074] Next, the server 30 receives the personal identification document (S109).

[0075] Then, the server 30 judges whether the facial photograph on the received personal identification document is the facial photograph of the owner (S113).

[0076] Then, the server 30 transmits the validity of the received personal identification document being the face photograph of the owner as a determination result (S117).

[0077] Then, the examination system 20 receives the judgment result of the examination target, and transmits the judgment result to the examination terminal 10 (S121).

[0078] Then, the examination terminal 10 displays the received judgment result (S125).

[0079] Then, at the examination terminal 10, examination and judgment are performed by the verifying person (S129), and the information processing system according to this embodiment ends the operation processing.

[0080] The above is a description of an example of the operation process of the information processing system according to the present embodiment. Next, with reference to Fig. 6, a description will be given of an example of the operation process in which the server 30 according to the present embodiment determines whether the face photograph on the personal identification document is the face photograph of the owner.

[0081] 6 is an explanatory diagram for explaining an example of the operation process of the server 30 according to this embodiment. First, the communication unit 33 receives an identification document with a user's face photo (S201).

[0082] Next, the recognition unit 351 recognizes the application data, various printed information, and the face photo, and the server 30 judges whether the various printed information is correct or not (S205). If the various printed information is correct (S205 / Yes), the process proceeds to S209, and if the various printed information is incorrect (S205 / No), the process of the server 30 according to this embodiment ends.

[0083] If the various types of printed information are correct (S205 / Yes), the recognition unit 351 detects feature information related to the outer frame of the face photograph included in the personal identification document (S209).

[0084] Then, the estimator 355 estimates standard feature information based on the print information included in the user's personal identification document (S213).

[0085] Next, the determination unit 357 determines whether the facial photograph included in the user's identification document is the owner's facial photograph based on the feature information related to the outer frame of the facial photograph on the user's identification document and the standard feature information (S217).

[0086] Then, the communication unit 33 transmits the validity of the photograph being the face of the owner as a determination result to the screening system 20 (S221), and the operation process of the server 30 according to this embodiment is terminated.

[0087] An example of the operation process of the server 30 according to this embodiment has been described above. Next, the effects of this embodiment will be described.

[0088] <<6. Effects of this embodiment>> According to the present embodiment described above, various operational effects can be obtained. For example, the server 30 according to the present embodiment can provide the verifying person with the validity that the face photograph included in the identification document is the face photograph of the owner, so that the verifying person can determine with higher accuracy whether the identification document has been tampered with.

[0089] In addition, the estimator 355 estimates standard feature information of the outer frame of the facial photograph based on the print information included in the identification document using the data learned by the learning unit. This allows the determination unit 357 to determine with higher accuracy whether the photograph is the owner's facial photograph based on the standard feature information on the outer frame of the facial photograph that may vary depending on the issuer and issue date of the identification document.
