Description

This invention relates to a test system, a test browser, and a test terminal, and in particular to a test system, a test browser, and a test terminal for conducting tests via the Internet.

Previously, various exams such as qualification exams and ability/scholastic ability tests basically required candidates to gather at one or more test locations and take the test using paper tests or test terminals. However, due to the recent spread of infectious diseases such as COVID-19, it remains difficult to take tests in groups at test locations, and there is an increasing need for candidates to take tests at home or other remote locations from various parties, including companies, educational institutions, and organizations that administer certification and accreditation exams.

When candidates take the exam remotely, as opposed to when they take the exam in a group, it is not possible to have a test supervisor supervise the candidates, so measures to prevent cheating are necessary.

Therefore, in the past, technology has been proposed in which an image of the examinee is captured by a camera or the like during the test, and the image is compared with a pre-registered identification image to verify the examinee's identity (Patent Documents 1 and 2). It has also been disclosed that a test is registered in advance using physical characteristic data, and authentication is then performed again using the physical characteristic data when the test data is sent during the test (Patent Document 3).

Referring to the figure, the examination system 1 is an IBT (Internet Based Testing) system that provides a service of conducting examinations via the Internet, and includes a face authentication server 21 that receives a request to register a personal image from a registration terminal 11 and registers the personal image in a personal image database 51, a matching request to the face authentication server 21 to match the examinee image sent from an examination terminal 12 with the personal image database 51, and an examination database 52 in which examination questions created by an examination question creation device 53 are registered, an examination server 22 that controls the examination, a scoring device 23 for scoring the examination results, and an evidence image matching device 24 for determining cheating. Note that the registration terminal 11, the face authentication server 21, and the examination server 22 are connected to each other so that they can communicate with each other, and the examination terminal 12 and the examination server 22 are connected to each other so that they can communicate with each other, via the Internet N.

Each terminal and server is equipped with a computer that includes a processing device such as a CPU (Central Processing Unit), various programs that are interpreted and executed on the processing device, and internal memory such as a RAM (Random Access Memory) for storing programs and various data, and the computer provides control means for executing various processes. The programs referred to here include basic control programs such as an OS (Operating System), and application programs that are launched on the OS and realize specific functions.

In addition, each terminal and each server is equipped with a storage unit for temporarily or permanently storing various data or programs to be processed, and this storage unit is composed of storage devices such as a main memory device, auxiliary storage devices such as a hard disk (HD) or built-in SSD (Solid State Drive), and external storage devices such as memory cards, external SSDs, and HDs.

Figure 2 is a functional block diagram showing an example of a registration terminal and a face recognition server that make up the test system shown in Figure 1, and Figure 3 is a functional block diagram showing an example of an examination terminal and a test server that make up the test system shown in Figure 1.

With reference to these diagrams, the details of each terminal and server are explained below.

(Registered terminal)
The registration terminal 11 is a terminal used for registering a personal image in the personal image database 51 and a test examinee list in the test database 52, and is configured as a smartphone. The registration terminal 11 can also be configured as a tablet terminal or other mobile terminal, a desktop PC (Personal Computer), or a notebook PC. The registration terminal 11 includes an imaging unit 111, and a test applicant information acquisition unit 110, a personal identification document information acquisition unit 112, a personal image registration request unit 113, and a test applicant information registration request unit 114, which are realized by application software installed in the registration terminal 11.

The imaging unit 111 is composed of a camera attached to the registration terminal 11 for capturing an image of a subject. In the registration terminal 11, the imaging unit 111 is used to capture an image of an identity verification document on which a facial photograph is printed, and to capture an image of a test applicant (test applicant capturing means).

The test applicant information acquisition unit 110 first requests the test applicant to provide information for registering the examinee list, including at least the name and date of birth of the test applicant, and transmits the information for registering the examinee list obtained in response to the request to the test database 52 via the test control unit 222 of the test server 22. In addition, the test database 52 creates a test examinee list based on the transmitted information for registering the examinee list.

The exam applicant information acquisition unit 110 also displays (gives) to the exam applicant the exam number and password acquired from the exam control unit 222 by searching the exam candidate list described below, and transmits the exam number to the exam applicant information registration request unit 114.

The identification document information acquisition unit 112 is used to determine the authenticity of an identification document that includes a face photo captured by the imaging unit 111 (identification document determination means) and to acquire a photo image based on the face photo (photo image acquisition means). An identification document refers to a document that certifies one's identity, and specific examples include a driver's license and a personal number card (My Number card). Note that other identification documents that include a face photo, such as a passport, may also be used. Determining the authenticity of an identification document means determining whether the document to be determined functions as an identification card or not. The identification document information acquisition unit 112 performs OCR (Optical Character Reader) processing on the identification document (document to be determined) captured by the imaging unit 111 to obtain the description, generates information about the identification document based on the description, and determines whether the document to be determined is created according to a predetermined format based on the generated information, depending on the type of identification document. If the document to be judged is prepared according to a prescribed format, the identity verification document information acquisition unit 112 judges that the document to be judged is a valid identity verification document. This judgment may be completed within the registration terminal 11, or may be obtained as a result of an inquiry via a network. In addition, this judgment may also judge the thickness and flatness of the document to be judged to determine whether it has been tampered with.

The identification document information acquisition unit 112 sends the acquired photographic image to the matching request acceptance unit 212 of the face authentication server 21, and also sends information on the validity of the identification document to the identification image registration request unit 113, which will be described below. In addition, it sends the name and date of birth written on the identification document to the examination control unit 222. The examination control unit 222 searches the transmitted name and date of birth from the examinee list in the examination database 52, and obtains the examination number and password corresponding to the transmitted name and date of birth from the examinee list and sends them to the examination applicant information acquisition unit 110.

The personal image registration request unit 113 transmits the image of the test applicant captured by the imaging unit 111 to the matching request reception unit 212 of the face authentication server 21, and receives from the matching request reception unit 212 the result of the judgment made by the matching request reception unit 212 as to whether the image of the test applicant matches the photographic image based on the face photograph published on the identification document. If the judgment result indicates a match and if the judgment information on the validity of the identification document is valid, then the identity is confirmed, and a registration request is made to the registration request reception unit 211 of the face authentication server 21 to request that the image of the test applicant be registered as the personal image.

The test applicant information registration request unit 114 requests the registration request receiving unit 211 to register the examination number received from the test applicant information acquisition unit 110 as test applicant information, linked to the personal image. The test applicant information may include various information written on the identification document according to a specified format. The various information written on the identification document may include, for example, name, date of birth, address, etc., and may be extracted by the above-mentioned identification document information acquisition unit 112.

(Facial recognition server)
The face authentication server 21 includes a registration request receiving unit 211 , a matching request receiving unit 212 , and a reference request receiving unit 213 .

The registration request receiving unit 211 registers the image of the test applicant as the personal image in the personal image database 51 based on the registration request for the personal image sent from the registration terminal 11 (registration means). In addition, the registration request receiving unit 211 registers the test applicant information including at least the examination number linked to the personal image in the personal image database 51 (test applicant information registration means). Note that the registration request receiving unit 211 may also register other test applicant information besides the examination number in association with the personal image in accordance with the registration request.

The matching request receiving unit 212 compares the applicant image and the photo image sent from the registration terminal 11, determines whether they match (image determination means), and sends the determination result to the personal image registration request unit 113. Based on the matching request sent from the test server 22, the personal image is matched with the examinee image described below to perform face authentication processing (matching means). Details of the face authentication processing will be described later.

The inquiry request reception unit 213 transmits the image of the person to the test server 22 based on the inquiry request transmitted from the test server 22 (inquiry means). Details of the inquiry request will be described later.

(Exam device)
The examination terminal 12 is a terminal used by examinees to take the examination, and is configured as a desktop PC or a notebook PC. It may also be configured as a smartphone, a tablet terminal, or other mobile terminal. The examination terminal 12 includes an imaging unit 121, an examinee information transmission unit 122, a password input unit 123, an answer creation unit 124, and an evidence image acquisition unit 125, which are realized on the Web.

The imaging unit 121 is composed of a web camera attached to the examination terminal 12 for capturing images of a subject. In the examination terminal 12, the imaging unit 121 is first used to capture an image of the examinee before the start of the examination (at the time of logging in). During the examination, the imaging unit 121 also captures an image of the examinee who performs a specific action, which will be described later. Furthermore, the image of the examinee may be captured at the start and end of the examination, or at any timing during the examination as necessary (examinee imaging means).

First, the examinee information transmission unit 122 transmits an examinee image captured by the imaging unit 121 before the start of the test to the matching request unit 221 of the test server 22 in order to authenticate the examinee's face. Note that the information transmitted to the matching request unit 221 may include other examinee information in addition to the examinee image.

When the examinee is authenticated in the facial recognition process described below, the password input unit 123 presents the examinee with the examination number linked to the examinee's image and requests the examinee to present a password. The password presented by the examinee is then transmitted to the test control unit 222 via the matching request unit 221.

The answer creation unit 124 is used to present test questions, accept answer creation operations, send answers, etc., when the examinee is authenticated in the face authentication process described below and the result of matching the examinee number and password is valid. For example, the answer creation unit 124 obtains test questions from the test server 22 and presents them to the examinee through a display unit (not shown) such as a display of the test terminal 12. The answer creation unit 124 also accepts answer creation operations from the examinee through an operation unit (not shown) such as a touch panel, and sends the answers to the test control unit 222 of the test server 22. The answer creation unit 124 may be capable of creating answers not only to multiple-choice questions but also to written questions. By adopting written questions as test questions, the examinee can be asked to give more complex answers than in the case of multiple-choice questions alone, which improves the accuracy of the evaluation of the examinee's understanding, and the test system 1 is more likely to prevent cheating and other misconduct. In the case of a multiple-choice question, the answer creation unit 124 creates an answer based on information indicating which option the examinee selected. In the case of a written question, the answer creation unit 124 may create an answer based on characters input using a keyboard, pen device, pointing device, etc., or may create an answer by capturing an image of characters or sentences written by hand or the like on a separate sheet of paper using the imaging unit 121 and reading them. Note that OCR processing may be used to read the contents written on the separate sheet and create an answer in the answer creation unit 124. Since OCR processing can also read vertically written documents, the answer creation unit 124 is suitable for creating answers in Japanese. In addition, the answer creation unit 124 may display an image of the characters or the like that has been read on the display unit, so that the examinee can submit it as an answer after determining whether it is possible to grade it. Furthermore, the answer creation unit 124 may transmit information to the test control unit 222 that an answer created by writing by hand or the like on a separate sheet of paper will be mailed separately.

The evidence image acquisition unit 125 acquires an image (evidence image) captured by the imaging unit 121 during a test when a specific action or the like occurs. The evidence image acquisition unit 125 also transmits the acquired evidence image to the test control unit 222 of the test server 22.

(Test Server)
The test server 22 includes a matching request unit 221 , a test control unit 222 , and an inquiry request unit 223 .

In response to an examinee image being sent from the examination terminal 12, the matching request unit 221 transfers the examinee image to the matching request receiving unit 212 of the face authentication server 21 and sends a request to match the examinee image and the examinee's image with the examinee's number (matching means). The matching request unit 221 also receives the results of the face authentication process from the face authentication server 21, and if the result shows that the examinee has been authenticated and an examinee number has been obtained by searching the examinee's image database 51, it instructs the examination terminal 12 to present the examinee's number at the password input unit 123 and to request the examinee to present his or her password. Furthermore, it transfers the password and examinee number sent from the examination terminal 12 to the examination control unit 222 and sends a password matching request (password matching means). Then, if the result of the face authentication is valid and the result of matching the examinee's number and password is valid, it instructs the examination control unit 222 to proceed with the examination (examination control means).

The test control unit 222 first compares the examination number and password transmitted via the comparison request unit 221 with the examination number and password in the examinee list registered in the test database 52 (password comparison means). If the examinee is identified as a result of the face authentication process and the comparison result between the examination number and the password is valid, the test proceeds (test control means). Specifically, the test control unit 222 transmits the test questions that have been read out in advance from the test database 52 and assigned to the examinee to the answer creation unit 124 of the test terminal 12 as the test proceeds. The test control unit 222 also receives the answer sheets that are created in the test terminal 12 according to the test questions and transmitted from the test terminal 12, and stores the contents in the test database 52. Furthermore, the test control unit 222 receives the evidence images transmitted from the evidence image acquisition unit 125, stores the contents in the test database 52, and transfers the evidence images stored in the test database 52 to the evidence image comparison device 24 in response to an inquiry from the evidence image comparison device 24 (evidence image comparison means).

In response to an inquiry from the evidence image matching device 24 via the test control unit 222, the query request unit 223 sends a query request for the person's image to the query request reception unit 212 of the face authentication server 21, and also sends the person's image sent from the query request reception unit 212 to the evidence image matching device 24 via the test control unit 222 (evidence image matching means).

(Exam question creation device)
The test question creation device 53 creates test questions and registers them in the test database 52. The test question creation device 53 uses a CBT (Computer Based Testing) system to create test questions through screen input or the like.

(Scoring device)
The marking device 23 is for marking answers to written questions written by examinees (marking means). The marking device 23 can be used by logging in by inputting a teacher code and a password that have been given to the examinee in advance. The marking device 23 queries the exam control unit 222 of the exam server 22, acquires the answers to the written questions of the examinees stored in the exam database 52, and presents them to the grader via a display unit (not shown). The grader grades the answers based on the presented answers to the written questions. When the marking device 23 transmits the marking results to the exam control unit 222, the marking results are stored in the exam database 52. Marking may be performed on the Web. Marking of answers to multiple-choice questions may be performed by the marking device 23 or may be automatically performed by another device not shown.
(Evidence image matching device)
The evidence image matching device 24 is for matching the evidence image and the person's image to determine whether or not there is any misconduct (evidence image matching means). The evidence image matching device 24 queries the test control unit 222, requests a comparison between the evidence image stored in the test database 52 and the person's image stored in the person's image database 51, obtains the evidence image and the person's image, and presents them to the misconduct judge via a display unit (not shown). The misconduct judge compares the evidence image and the person's image presented to the evidence image matching device 24 to determine whether or not there is any misconduct. The result of the determination as to whether or not there is any misconduct is also transmitted to the test control unit 222 and stored in the test database 52. In this manner, the grading is completed.

After grading is complete, if the result of matching the examination number and password entered via the examination terminal 12 is valid, the examination result corresponding to the examination number is displayed on the examination terminal 12, and the examinee is notified of the examination result. The notification of the examination result may indicate only pass/fail, or may indicate the specific grade (score). Furthermore, the matching before notifying the examination result may include facial recognition.

The processing flow in the test system is explained below.

FIG. 4 is a flow chart showing the flow of processing in the examination system shown in FIG. 1, where (1) shows the registration processing and (2) shows the examination processing.
(Registration process flow)
1 to 3 and (1) of FIG. 4, in the examination system 1, in response to the user's operation, the registration process (S1) of the applicant's image is started in the registration terminal 11. Here, the user may be the applicant who will be the examinee, or an operator who assists the applicant in the registration process. For example, a registration station equipped with the registration terminal 11 may be provided, and a dedicated operator may assist the applicant in the administrative process of the registration process on behalf of the applicant who is unfamiliar with the operation, thereby lowering the hurdle for the applicant in the registration process.

When the registration process is started, first, the image capture unit 111 of the registration terminal 11 reads the identification document (S11). At this time, the type of identification document to be judged may be selected. Next, the identification document information acquisition unit 112 judges the authenticity of the identification document on which the face photo is published. Specifically, the identification document information acquisition unit 112 judges whether the identification document to be judged is created according to a predetermined format (S12). If the document to be judged is created according to a predetermined format, then, the identity matching process is performed (S13). In the identity matching process, the matching request acceptance unit 212 of the face authentication server 21 first acquires a photo image based on the face photo published on the identification document from the identification document information acquisition unit 112, and acquires the test applicant image captured by the image capture unit 111 from the identity image registration request unit 113. The matching request acceptance unit 212 judges whether the photo image thus acquired matches or does not match the test applicant image. Well-known pattern recognition techniques can be used to determine whether the images match or not.

If the photograph image and the test applicant image match, the personal image registration request unit 113 sends the test applicant image to the registration request reception unit 211 of the face authentication server 21 and makes a personal image registration request to register the test applicant image as the personal image. The test applicant information registration request unit 114 also requests the registration request reception unit 211 to register at least the examinee number as test applicant information linked to the personal image. In response to these registration requests, the registration request reception unit 211 of the face authentication server 21 links the personal image and examinee number to the personal image database 51, and also registers various information associated therewith (S14). This completes the registration process.

The application for the exam may be accepted at the same time as the registration process, or the application for the exam may be accepted separately from the registration process. Furthermore, the application for the exam may involve authentication processing using an examinee number and password that is separate from the registration process.

Furthermore, when the registration process is normally completed, some or all of the information collected for the registration request may be deleted from the registration terminal 11. For example, the information to be deleted includes the photo image and the image of the applicant for the test, the description obtained by applying OCR processing based on the identification document, and the result of the match/mismatch between the photo image and the image of the applicant for the test. This improves information security.
(Examination process flow)
1 to 3 and (2) of FIG. 4, in the examination system 1, as the examination process (S2), first, an operation to enter the online venue of the applied examination is accepted in the examination terminal 12 (S21). In response to this, a matching process at the time of entry is carried out in the examination terminal 12 (S22). First, an examinee image captured by the imaging unit 121 of the examination terminal 12 is sent to the matching request unit 221 of the examination server 22. In response to this, the examination server 22 sends a matching request together with the examinee image to the matching request receiving unit 212 of the face authentication server 21. In the face authentication server 21, the matching request receiving unit 212 matches the examinee image with the examinee image based on the matching request sent from the examination server 22. If the examinee is authenticated as a result of the face authentication server 21, the examination terminal 12 further requests the presentation of a password and performs matching of the password sent to the examination control unit 222 via the matching request unit 221. By carrying out the matching process in two stages in this way, it is possible to enhance the effect of deterring and preventing cheating. If the facial authentication result and the password matching result are both valid, the test server 22 instructs the test control unit 222 to proceed with the test. As a result, the test terminals 12 enter the test room and wait for the test start time. The test may start all at once on a specified date and time, or may be able to start at any time selected by the user. An authentication process may also be executed when the test starts. The start of the test refers to the period from when the test room entry is accepted until the test starts.

When the test begins, test questions and their answers are exchanged via communication between the test server 22 and the test terminal 12 (S23). During the test implementation process, on the test terminal 12, when the test taker performs a specific action or an action that may be fraudulent, the imaging unit 121 captures an image of the test taker, and the evidence image is acquired by the evidence image acquisition unit 125 each time.

A specific action is, for example, when the face goes out of the frame of the image capture range or when that state continues for more than a predetermined time. A potentially fraudulent action is one that is suspected of being a tampering such as cheating, for example, when the face goes out of the frame of the image capture range, the eyes are not on the screen, or another person is in the picture. Evidence images acquired in response to potentially fraudulent actions are used later to determine whether or not there has been any fraud. Details will be given later. In this way, records of specific actions and potentially fraudulent actions can be collected without interrupting the test.

The test will end normally when the test time has elapsed or when the test taker has performed the exit action.

When the test ends normally, a misconduct judgement is made (S24). In judging misconduct, first, the evidence image acquisition unit 125 of the examination terminal 12 transmits the evidence image acquired in response to the possibly fraudulent action to the examination control unit 222 of the examination server 22. The examination control unit 222 of the examination server 22 stores this evidence image in the examination database 52. The evidence image may be registered in association with the examination result. As a specific method of judging misconduct, the misconduct judge compares and judges the evidence image and the person's image that can be acquired by the evidence image matching device 24 in response to a reference request for examinees who have passed the marking. In this way, the person's image and the imaging unit 121 of the examination terminal 12 can be used not only to match the examinee but also to judge misconduct. In addition, since the misconduct judge actually compares the evidence image and the person's image to make a judgment, for example, for examinees who have been forced to perform specific actions or actions that may be fraudulent due to physical characteristics due to a handicap, a judgment can be made taking into account the physical characteristics, making the system user-friendly.

Regardless of the score, the evidence image and the person's image may be checked by a cheating judge to determine whether or not cheating has occurred. Also, an AI function that has been trained on the detection of cheating may be used to compare and analyze the evidence image and the person's image to detect cheating. Furthermore, the evidence image used to determine cheating may not only be an image taken during the test, but may also be an image taken before the start of the test, at the start of the test, or at the end of the test. This completes the test-taking process.
(Brief Summary)
As described above, the examination system 1 includes an identification document information acquisition unit (identification document determination means, photo image acquisition means) 112 that determines the authenticity of an identification document containing the examinee's photograph and acquires a photo image based on the face photograph published on the identification document, and an applicant image registration request unit (exam applicant image acquisition means, registration means) 113 that acquires an applicant image and requests the face authentication server (registration means) 21 to register an image of the applicant's appearance as an applicant image when the applicant image is found to be authentic and the face authentication server 21 (image determination means) finds that the applicant image matches the photo image. The examination terminal 12 also includes an examinee information transmission unit (exam examinee imaging means, comparison means) 122 that transmits the examinee image to the examination server 22 by having the examinee image captured by an imaging unit (exam examinee imaging means) 121 at least before the start of the examination. Furthermore, the facial authentication server 21 is provided with a matching request receiving unit (matching means) 212 for matching the photographic image acquired via the personal identification document information acquiring unit (photographic image acquiring means) 112 of the registration terminal 11 with the applicant image acquired via the imaging unit (applicant imaging means) 111 and the applicant image registration request unit 113, and also the examinee image acquired via the matching request unit (matching means) 221 of the exam server 22 with the registered applicant image, and the exam server 22 is provided with an exam control unit (exam control means) 222 for receiving the result of the facial authentication process from the facial authentication server 21 at the matching request unit 221, and starting the exam in response to an instruction from the matching request unit 221 if the examinee image and the applicant image match and if the matching result between the examinee number and the password is valid. Further, the exam server 22 is provided with a marking device (marking means) 23 for marking exam papers.

In this way, the authenticity of the identification documents can be determined before verifying the identity of the examinee, making it possible to more reliably verify the identity of the examinee.

Furthermore, with the examination system 1, it is possible to attract a wide range of examinees. For example, with conventional group examinations, the venues tended to be concentrated in urban areas, but with the examination system 1, examinees in rural areas can also take the examination without any burden. Furthermore, it also becomes possible for examinees with disabilities who have difficulty traveling to take the examination.

In addition, in the test system 1, the face recognition server and the test server work together, so it is possible to share the roles of face recognition function and test function between the servers. This improves development efficiency.

Furthermore, the imaging unit 121 (examinee imaging means) captures an image of the examinee when the examinee performs a specific action.

In this way, images can be captured when the examinee performs a specific action, which reduces the amount of data generated compared to when images are captured continuously. An example of a case where images are captured continuously is when capturing video.

Furthermore, the evidence image matching device (evidence image matching means) 24 makes it possible to match the image of the person in question with the evidence image.

In this way, after the test is completed, the images captured up to that point can be compared, making it possible to determine whether the test was taken legitimately by the person in question.

Furthermore, the identity verification document determination unit 112 generates information about the identity verification document based on the items recorded on the identity verification document, and determines the legitimacy based on the generated information.

This makes it easier to use the system because the authenticity of the identity document can be determined based on the information contained on the identity document.

Furthermore, the examination system 1 includes an examination applicant information registration unit 114, which links the examination applicant's examination number and password given to the examination applicant with an image of the applicant and registers them as examination applicant information, a registration request acceptance unit 211, and an image database 51 (examination applicant information registration means), an examination question creation device 53 (examination question creation means) that registers questions created using a computer as examination questions, a password input unit 123, a matching request unit 221, and an examination control unit 222 (password input unit 123) that presents the examination number to the examinee and requests the examinee to present a password when a match is confirmed between the examinee's image captured before the start of the examination and the examinee's image. the password matching means), a matching request unit 221 that starts the test using the registered test questions if it is confirmed that the password presented by the examinee matches the password registered in the test database 52 and given to the test applicant, and a test control unit 222 (test control means), a marking device 23 (marking means) that enables marking of test answers, an evidence image matching device 24 (evidence image matching means) that enables the capture of evidence images captured by the image capture unit 121 (examinee image capture means) when the examinee performs a specific action during the test and an image of the examinee, and an examination terminal 12 (examination result notification means) that notifies the examinee of the test results after marking is completed.

In this way, each component (means) from applying for the exam, creating the exam questions, conducting the exam, marking, and notifying the exam results are linked to each other, resulting in an easy-to-use exam system 1.

(Modification)
In the above embodiment, the registration terminal and the examination terminal are described as separate terminals, but this is not limited to the above. A test terminal that realizes both the functions of the registration terminal and the examination terminal described above on one terminal may be used. In this way, the authenticity of the identification document can be determined on the test terminal, and then the identity of the examinee can be confirmed, thereby realizing a test terminal that can more reliably confirm the identity of the examinee. It is more preferable that the test terminal has no functions other than the registration terminal function and the examination terminal function.

In the above embodiment, a terminal with a specific configuration has been described as a registration terminal or an examination terminal, but by installing a test browser with the functions of both the registration terminal and the examination terminal, any terminal with the functions of both the registration terminal, the examination terminal, or both the registration terminal and the examination terminal may be a terminal with both the functions of the registration terminal, the examination terminal, or both the registration terminal and the examination terminal. In this way, the examination browser can determine the authenticity of the identity document and then verify the identity of the examinee, so that a test browser that can verify the identity of the examinee more reliably can be realized. Regarding the examination terminal function, it is more preferable if the test browser only connects to the online venue (examination site) of the applied examination and cannot display other sites. It is also more preferable if the test browser is displayed full screen on the display unit of the examination terminal and cannot be switched to other screens. It is also more preferable if the clipboard and copy functions are disabled.

In addition, in the above embodiment, the face recognition server and the test server are described as separate server devices, but this is not limited to the above. The face recognition server and the test server may be implemented on a single server device, or each of the face recognition server and the test server may be configured as multiple server devices rather than a single server device.

Generally, when many test takers access one server device simultaneously from various locations, such as their homes, response times tend to slow down. However, by implementing an exam system using a group of server devices, it is possible to distribute the servers using a load balancer and to multi-spread (handle multiple test takers at the same time), improving response times.

In addition, by making the server and network equipment redundant and logging client operations in real time, if a problem does occur, the most recent log state can be reproduced and a resume function can be provided to allow the exam to be taken immediately from where it left off.

Furthermore, in the above embodiment, the identification document determination unit generates information about the identification document by performing OCR processing on the identification document, but this is not limited to this. If the identification document is equipped with a storage device such as an IC chip, and information about the identification document is stored in this storage device, this may be read out. That is, the identification document determination unit may read information about the identification document from the storage device equipped in the identification document by NFC (Near Field Communication), and determine the authenticity based on the read information. This makes it possible to accurately determine the authenticity of the identification document based on the information stored in the storage device equipped in the identification document, resulting in a user-friendly system.

Furthermore, in the above embodiment, the examination system only handles the examination process, but it may also notify the examination results after the examination process is completed. The examination results are notified, for example, by requesting the examinee's examination number and password when logging in to the examination result notification venue, and if the examination number and password match is valid, the results of the examinee are displayed on the web.

Furthermore, in the above embodiment, the identity of the test applicant and test taker is confirmed by facial recognition, but biometric authentication such as fingerprint authentication, iris authentication, or vein authentication may be used instead of facial recognition.

Furthermore, in the above embodiment, when a specific action or an action that may be fraudulent is detected, the examinee is simply photographed, but it is also possible to display a warning message on the display unit of the examination terminal, or to forcibly terminate the test depending on the number of failures.

Furthermore, in the above embodiment, the evidence images and the examinee's image were checked by a cheating judge to determine whether cheating had occurred, but if a predetermined number of evidence images or more are saved, it may be possible to assume that cheating has occurred and automatically fail the examinee.

Furthermore, in the above embodiment, the examinee imaging means captures evidence images and is equipped with an evidence image matching device, but the examinee imaging means does not have to capture evidence images and does not have to be equipped with an evidence image matching device.
