Description

This disclosure relates to a display control system, a display control method, and a program.

Conventionally, various authentication methods have been implemented to verify the legitimacy of users. For example, Patent Literature 1 describes a technology in which a first terminal displays a first content including an input form for inputting information required for applying for a payment service and a two-dimensional code as authentication information, and when a user who wishes to upload an identity verification document from a second terminal reads the two-dimensional code of the first content with the second terminal, the second content reflecting the information inputted into the input form of the first content is displayed on the second terminal. In such an application, the user may be required to perform some kind of authentication in order to complete the application.

JP 2022-055620 A

However, with the technology of Patent Document 1, a user may accidentally close the first content and the second content when attempting to open a screen for performing authentication. In this case, the user must re-enter the information required for application from the beginning. This is not limited to when applying as in Patent Document 1, but is similar in other situations where authentication is required. For this reason, conventional technology has not been able to sufficiently improve user convenience.

One of the objectives of this disclosure is to improve user convenience.

The display control system according to the present disclosure includes a storage unit that stores at least a portion of the input information entered into an input screen that accepts input of the input information, an authentication unit that executes authentication required for a procedure performed from the input screen, which requires displaying a screen different from the input screen when an authentication start operation that can be performed at any time while the input screen is displayed is performed, and a display control unit that displays the input screen based on the input information stored by the storage unit when the authentication is completed.

This disclosure improves user convenience.

[1. Overall configuration of the display control system]
An example of an embodiment of a display control system according to the present disclosure will be described. Fig. 1 is a diagram showing an example of an overall configuration of a display control system. For example, the display control system 1 includes a server 10 and a user terminal 20. Each of the server 10 and the user terminal 20 is connected to a network N such as the Internet or a LAN.

The server 10 is a server computer. For example, the server 10 includes a control unit 11, a memory unit 12, and a communication unit 13. The control unit 11 includes at least one processor. The memory unit 12 includes a volatile memory such as a RAM, and a non-volatile memory such as a flash memory. The communication unit 13 includes at least one of a communication interface for wired communication and a communication interface for wireless communication.

The user terminal 20 is a user's computer. For example, the user terminal 20 is a personal computer, a smartphone, or a tablet. The user terminal 20 includes a control unit 21, a memory unit 22, a communication unit 23, an operation unit 24, and a display unit 25. The physical configurations of the control unit 21, the memory unit 22, and the communication unit 23 may be similar to those of the control unit 11, the memory unit 12, and the communication unit 13, respectively. The operation unit 24 is an input device such as a keyboard, a mouse, or a touch panel. The display unit 25 is a display such as a liquid crystal display or an organic EL display.

The programs stored in the storage units 12 and 22 may be supplied via the network N. Also, the programs stored in a computer-readable information storage medium may be supplied via a reading unit (e.g., an optical disk drive or a memory card slot) that reads the information storage medium, or an input/output unit (e.g., a USB port) that inputs and outputs data to and from an external device.

The display control system 1 is not limited to the example of FIG. 1 as long as it includes at least one computer. For example, the display control system 1 may include only the server 10 without including the user terminal 20. In this case, the user terminal 20 exists outside the display control system 1. The display control system 1 may include only the user terminal 20 without including the server 10. In this case, the server 10 exists outside the display control system 1.

2. Overview of the display control system
In this embodiment, an example of the display control system 1 will be described taking as an example a situation in which a user applies for a payment service. The payment service is a service that provides electronic payment (cashless payment). Any payment method can be used in the payment service. For example, in the payment service, a credit card, a debit card, electronic money, a wallet, points, an account such as a bank account, or cryptocurrency can be used as a payment method.

In this embodiment, an example is taken of a case where the person receiving payment in a payment service corresponds to the user. For example, the user is a person in charge of a store considering joining the payment service. The user applies for the payment service in order to register his or her store as an affiliated store. When the user operates the user terminal 20 to access the server 10, an input screen for inputting information required for the application is displayed on the display unit 25.

Figure 2 is a diagram showing an example of an input screen. In this embodiment, an example is given of a case where the input screen SC1 is displayed in a browser, but the input screen SC1 may also be displayed in an application other than a browser (for example, an application dedicated to a payment service). In the example of Figure 2, the input screen SC1 is displayed in a first tab T1 of a browser window W1. The browser window W1 is a browser window. Any number of tabs can be displayed in the browser window W1. The browser window W1 may be a window without the concept of tabs. Furthermore, there may be no distinction between tabs and windows.

For example, the user inputs the information required for application, such as name, date of birth, email address, and address, into input form F on input screen SC1. Hereinafter, the information input into input screen SC1 will be referred to as input information. Input information may be any information and is not limited to the user's personal information. For example, input information may include information such as the store name or representative, the content of the service the user desires, payment method information, transfer account information, or questions about the payment service.

In this embodiment, an example is given in which an application is made through seven steps, including "Basic", "Store", "Account", "Confirm", "Document Confirmation", "Submit", and "Complete". Furthermore, for each step, a page is displayed that requests some input from the user. For this reason, the input screen SC1 is made up of seven pages. The main part of the URL of each page other than the arguments (the part before "?" in the example of Figure 2) is the same, but the main part of the URL may be different for each page. Furthermore, there may be required input items to proceed from one step to the next.

The application itself may be carried out in any flow and is not limited to the example of this embodiment. For example, the number of steps and pages required for the application may be any number and is not limited to seven. The application does not have to be divided into multiple steps, and multiple steps may be combined on one page. The layout of the input screen SC1 may also be any layout and is not limited to the example of this embodiment. For example, the input screen SC1 may be composed of only one page.

In this embodiment, the user must perform authentication to complete the application. The user can perform authentication at a time that is convenient for the user. In the example of FIG. 2, the application is completed when the user proceeds to the "Complete" step, so the user can perform authentication at any step from the "Basic" step to the "Submit" step. For example, an authentication window W2 for starting authentication is displayed so as to be superimposed on the input screen SC1. When the user scrolls the input screen SC1, the authentication window W2 also moves.

Figure 3 is a diagram showing an example of the authentication window W2 when the user scrolls the input screen SC1. For example, the authentication window W2 moves in the direction in which the input screen SC1 is scrolled. In this embodiment, the display position of the authentication window W2 in the first tab T1 does not change. That is, the relative positional relationship between the parts in the input screen SC1 (for example, text such as "Contractor's name" and the input form F) and the authentication window W2 changes due to scrolling, but the absolute position of the authentication window W2 in the first tab T1 does not change.

The authentication window W2 may be configured to be able to be moved, minimized (folded), or closed by a user operation. If the authentication window W2 is configured to be able to be minimized or closed, the authentication window W2 may be configured to be redisplayed by a user operation. The authentication window W2 may be automatically redisplayed without requiring a user operation when a predetermined step has been reached in a series of procedures. The authentication window W2 may not be displayed initially, but may be displayed when a certain step has been reached.

For example, when authentication is complete, the authentication window W2 disappears. Therefore, until authentication is complete, the authentication window W2 is displayed on the page to which the user transitions, regardless of which page the user transitions to. For example, if the user proceeds to the "Store" step without performing authentication on the "Basic" step page, the authentication window W2 is displayed on the "Store" step page. If the user returns to the "Basic" step page without performing authentication on the "Store" step page, the authentication window W2 is displayed on the "Basic" step page.

Figure 4 is a diagram showing an example of a flow in which a user starts authentication. For example, the user can start authentication by selecting button B1 in authentication window W2. In this embodiment, email authentication using email is described as an example of authentication. The authentication itself may be of any type and is not limited to the example of this embodiment. For example, SMS (Short Message Service) authentication, authentication using a message app or a message function of an SNS (Social networking service), outgoing phone call authentication, incoming phone call authentication, password authentication, biometric authentication, password authentication, or possession authentication using a personal number card may be performed.

For example, when the user selects button B1, an authentication e-mail is sent to the e-mail address entered by the user. In this embodiment, the e-mail is sent to the e-mail address entered on the "Basic" step page, but the e-mail may be sent to another e-mail address. For example, the e-mail may be sent to an e-mail address entered in advance to display the input screen SC1. As shown in FIG. 4, the authentication window W2 displays a message prompting the user to confirm the e-mail. The user can also send the e-mail again by selecting button B2. The user can also change the e-mail address and then select button B2. The user confirms the e-mail and completes the authentication.

Figure 5 is a diagram showing an example of an email. In this embodiment, an example is shown in which an email is displayed in a browser, but the email may also be displayed in an application other than a browser (for example, an application dedicated to email). In the example of Figure 5, an email screen SC2 showing the contents of the email is displayed in the email tab MT of the same browser window W1 as the first tab T1.

For example, the authentication email includes a link L for completing the authentication. In this embodiment, the portion of the URL of the link L other than the arguments (the portion before "?" in the example of FIG. 5) is the same as the URL of the input screen SC1. For example, the URL of the link L has some of the arguments of the URL of the input screen SC1 hashed, and does not include other portions of the arguments of the URL of the input screen SC1.

For example, the URL of input screen SC1 includes a first argument ("sessionid=123456" in the examples of Figs. 2 to 5) and a second argument ("step=1" in the examples of Figs. 2 to 5). The first argument is a session ID that can identify a session established between the server 10 and the user terminal 20. If the session is maintained, the first argument does not change. The second argument is a step ID that can identify the step at which the page is being displayed on input screen SC1. If a page transition occurs on input screen SC1, the second argument changes.

In this embodiment, the first argument of link L is hashed, so that even if the email address is incorrect, the risk of the session ID being leaked can be reduced. The reason why the second argument is not included in link L will be described later. When the user selects link L, authentication is completed. When the user completes authentication, an input screen SC1 reflecting the input information held by server 10 is displayed in a second tab T2, which is a new tab in browser window W1.

For example, the second tab T2 displays an input screen SC1 similar to the first tab T1. In the example of FIG. 5, the second tab T2 displays an input screen SC1 similar to the first tab T1 in FIG. 4 immediately before authentication begins. The input screen SC1 may display information indicating that authentication has been completed. In this embodiment, it is assumed that the server 10 holds the input information. Therefore, even if the user accidentally closes the first tab T1 or the browser window W1 in an attempt to display the mail screen SC2, the input screen SC1 reflecting the input information that has already been entered can be displayed by selecting the link L.

In this embodiment, the server 10 stores information that can identify the currently displayed page among the multiple pages of the input screen SC1. The page that is displayed in the second tab T2 after the user selects the link L is the page that was displayed by the user until recently. For example, even if the user transitions to another page of the input screen SC1 after the authentication email is sent, when the user selects the link L, the other page that was displayed until recently is displayed.

Figure 6 is a diagram showing an example of a case where the page of input screen SC1 changes after an authentication e-mail has been sent. In Figure 6, the specific content portion in browser window W1 has been omitted. The pattern in the upper part of Figure 6 is the flow described with reference to Figures 2 to 5. As in the pattern in the lower part of Figure 6, after button B1 is selected on the "Basic" step page of input screen SC1 and an e-mail is sent, the page transitions to the next "Store" step page. If the user then displays email screen SC2 and selects link L, the page of the "Store" step is displayed, instead of the page of the "Basic" step that was displayed when button B1 was selected.

In this embodiment, the server 10 stores information that can identify which page is to be displayed when link L is selected. This information may be included in link L, but in this case, in the case of the pattern in the lower part of Figure 6, information for returning to the page of the "Basic" step is included in link L. As a result, the page is returned to the "Basic" step page, rather than the "Store" step page. In this regard, by deliberately not including this information in link L, it is possible to return to the page of the "Store" step. The above-mentioned reason is why this information is not included in link L.

As described above, in this embodiment, in order to perform authentication, it is necessary to display the mail screen SC2, which is a screen different from the input screen SC1. When displaying the other screen, the user may accidentally close the input screen SC1 on which the user had been entering data. In this regard, the input information stored in the server 10 can prevent the user from having to start inputting data over again even if the user accidentally closes the input screen SC1, thereby improving user convenience. Details of the display control system 1 will be described below.

[3. Functions Realized by the Display Control System]
FIG. 7 is a functional block diagram showing an example of functions realized by the display control system 1. As shown in FIG.

[3-1. Functions realized by the server]
For example, the server 10 includes a data storage unit 100, a saving unit 101, a determination unit 102, an authentication unit 103, a display control unit 104, and an application receiving unit 105. The data storage unit 100 is realized by the storage unit 12. The saving unit 101, the determination unit 102, the authentication unit 103, the display control unit 104, and the application receiving unit 105 are realized by the control unit 11.

[Data storage unit]
The data storage unit 100 stores data necessary for applications from users. For example, the data storage unit 100 stores a saved database DB.

Figure 8 is a diagram showing an example of the saved database DB. As shown in Figure 8, the saved database DB is a database for saving input information. For example, the saved database DB stores a session ID, a hashed session ID, display portion information, input information, an authenticated flag, and an expiration date. Any information may be stored in the saved database DB. The information stored in the saved database DB is not limited to the example in Figure 8. For example, if an email is sent to an email address entered before displaying the input screen SC1, this email address may be stored in the saved database DB. The saved database DB may also store a URL included in the link L.

The session ID is information that can identify a session established between the server 10 and the user terminal 20. The session ID can be generated using various known methods. For example, the server 10 generates the session ID based on a random number generation function. In this embodiment, the validity period of the session ID is set. The server 10 generates the session ID so that the value is not the same as any other session ID within the validity period. When the user selects button B1, a hashed session ID is generated and stored in the storage database DB.

The session ID is an example of user identification information that can identify a user. Therefore, the section written as session ID can be read as user identification information. User identification information can also be said to be information that can identify the user terminal 20. User identification information may be other information and is not limited to a session ID. For example, user identification information may be the IP address of the user terminal 20, information in the SIM card such as a telephone number, the terminal name, a MAC address, or an individual identification number. User identification information may also be other information that is dynamically generated like a session ID (for example, a one-time password).

The display portion information is information about the currently displayed portion of the input screen SC1. In this embodiment, since the input screen SC1 is made up of seven pages, the display portion information indicates the page number of the currently displayed page. For example, display portion information of "01" means that it is the page of the "Basic" step. Similarly, display portion information of "02" to "07" means that it is the page of the "Store" step, the "Account" step, the "Confirm" step, the "Document Confirmation" step, the "Submit" step, and the "Complete" step, respectively.

The display portion information may indicate the portion of a page that is currently being displayed, rather than the page number. The display portion information may indicate the page number of the currently displayed page and the portion of this page that is currently being displayed. For example, the display portion information may indicate the vertical position of a page. For example, the vertical position is the amount of scrolling from the top end. The display portion information may be the position of a section within a page, rather than the amount of scrolling. For example, if the input screen SC1 is not divided into multiple pages, the display portion information may indicate only the vertical position of the input screen SC1, without including the page number.

The input information is information entered into the input screen SC1. In the example of FIG. 2, the input information includes letters, numbers, other symbols, or combinations of these entered into the input form F of the input screen SC1. The input information is not limited to information entered as text, and may be files such as images, videos, or documents uploaded by operation from the operation unit 24. In the example of FIG. 8, the input information also includes the item names of the input form F, but the input information does not have to include the item names.

The authenticated flag is information indicating whether or not authentication has been performed. For example, the authenticated flag indicates a first value, which means that authentication has been performed, or a second value, which means that authentication has not been performed. When a session is established between the server 10 and the user terminal 20, an authenticated flag with a first value is generated. When authentication is completed by the authentication unit 103 described below, the authenticated flag is changed from the first value to the second value.

The expiration date is the end point of the period during which the session ID is valid. For example, when the server 10 establishes a session with the user terminal 20 and generates a session ID, the server 10 sets the expiration date to a point a certain amount of time after that point (for example, any time between 1 minute and 30 days, longer or shorter). The server 10 may update the expiration date each time communication is performed between the server 10 and the user terminal 20. The expiration date of the hashed session ID may be stored in the storage database DB separately from the expiration date of the session ID.

The data stored in the data storage unit 100 is not limited to the above example. The data storage unit 100 can store any data. For example, the data storage unit 100 stores display data for displaying the input screen SC1. When a browser is used as in this embodiment, the display data is data in HTML format. When a dedicated application other than a browser is used, the display data may be image data for displaying some kind of screen in the application.

[Storage section]
The storage unit 101 stores at least a part of the input information inputted to the input screen SC1 that accepts input of the input information. For example, the user terminal 20 transmits the input information inputted to the input screen SC1 to the server 10 by executing a script included in the display data of the input screen SC1. The transmission of the input information may be periodically executed at a predetermined cycle, or may be triggered by some input by the user (for example, a key input to the operation unit 24 or focusing on the input form F).

In this embodiment, the storage unit 101 associates the input information with identification information capable of identifying the input information and stores the associated information in the server 10. A session ID will be described as an example of identification information capable of identifying the input information. Therefore, the section describing the session ID can be read as identification information capable of identifying the input information. The identification information capable of identifying the input information may be information other than the session ID. For example, the identification information capable of identifying the input information may be the user identification information described above, or may be an ID that is generated each time input information is input.

For example, when the storage unit 101 receives input information from the user terminal 20, it associates a session ID capable of identifying a session with the user terminal 20 with the received input information and stores them in the storage database DB. The user terminal 20 transmits the session ID together with the input information to the server 10. At least one of the session ID and the input information may be encrypted before transmission. If the input information is to be stored in a database other than the storage database DB, the storage unit 101 may store the input information in the other database. If the input information is stored in a computer other than the server 10, the storage unit 101 may store the input information in the other computer.

In this embodiment, the user can input some input information, perform authentication, and then input the remaining input information. Hereinafter, input information input before authentication is referred to as first input information. Input information input after authentication is referred to as second input information. When there is no need to distinguish between these, they are simply referred to as input information. For example, the storage unit 101 stores the first input information input into the input screen SC1. In the example of Figures 4 and 5, the name, date of birth, and email address input before authentication correspond to the first input information. The address and other information input after authentication correspond to the second input information.

For example, the storage unit 101 stores the input information entered in the input screen SC1 displayed in the first tab T1 of the browser. In this embodiment, since the second tab T2 is displayed after authentication, this input information is the first input information described above. The input screen SC1 after authentication may be displayed in the existing first tab T1, rather than opening a new second tab T2. In this case, both the first input information and the second input information are entered in the first tab T1, and the storage unit 101 stores both the first input information and the second input information entered in the first tab T1. When the user performs authentication at the end of the application, there is no second input information to be entered, so the storage unit 101 stores the first input information entered in the first tab T1 without storing the second input information.

Note that the input screen SC1 after authentication may be displayed in a window separate from the window before authentication. In this case, the browser window W1 that displays the input screen SC1 before authentication is referred to as the first window. The separate browser window after authentication is referred to as the second window. When there is no need to distinguish between these, they are simply referred to as windows. The storage unit 101 may store the input information entered into the input screen SC1 displayed in the first tab or window of the browser.

In this embodiment, the storage unit 101 further stores display portion information related to the portion of the input screen SC1 that is currently being displayed. For example, the user terminal 20 executes a script included in the display data of the input screen SC1 to send a page transition request to the server 10 to transition to the next page. The page transition request is data in a predetermined format that indicates a page transition. It is assumed that the page transition request includes the page number of the page to be transitioned to.

In this embodiment, since the input screen SC1 is composed of seven pages, the page transition request includes a number from "01" to "07" as the page number of the transition destination page. The display portion information may be transmitted from the user terminal 20 to the server 10 periodically, rather than at the timing of the page transition. The periodic transmission is as described in the process of saving the input information.

The storage unit 101 can store the input information at any timing. The timing at which the storage unit 101 stores the input information is not limited to the example of this embodiment. For example, when an authentication start operation is performed, the user terminal 20 may transmit the input information input up to that point to the server 10. In this case, the user terminal 20 does not transmit the input information to the server 10 until the authentication start operation is performed. The server 10 receives the input information transmitted when the authentication start operation is performed. The storage unit 101 stores the received input information.

For example, an input information save operation for saving input information may be performed as an operation separate from the authentication start operation. The input information save operation may be any operation. For example, a button for instructing the saving of input information may be displayed on the input screen SC1, and selecting this button may correspond to the input information save operation. The input information save operation may be an operation of selecting a specific key on the keyboard, or an operation of displaying a window superimposed on the input screen SC1. When the input information save operation is performed, the storage unit 101 saves the input information received from the user terminal 20.

[Determination section]
The determination unit 102 determines whether or not an authentication start operation has been performed, which can be performed at any timing while the input screen SC1 is displayed. The authentication start operation is an operation for starting authentication. In this embodiment, a case will be described in which the operation of selecting the button B1 in the authentication window W2 corresponds to the authentication start operation, but the authentication start operation may be any operation or may be another operation. For example, the authentication start operation may be an operation of selecting an image other than the button B1 displayed in the authentication window W2.

The authentication start operation does not have to be an operation on the authentication window W2 superimposed on the input screen SC1. For example, if an image for starting authentication is displayed on the input screen SC1, the authentication start operation may be an operation of selecting this image. For example, the authentication start operation may be an operation of tapping or flicking a location where the input screen SC1 and the authentication window W2 are not displayed. Furthermore, the authentication start operation is not limited to an operation on the operation unit 24. For example, the authentication start operation may be an operation using voice or gestures.

For example, when the user selects button B1, the user terminal 20 transmits an authentication start request to the server 10 to request the start of authentication. The authentication start request is data in a predetermined format for starting authentication. The determination unit 102 determines whether an authentication start operation has been performed by determining whether an authentication start request has been received from the user terminal 20. In this embodiment, the authentication start operation can be performed from any of the multiple pages included in the input screen SC1.

[Authentication section]
When it is determined that an authentication start operation has been performed, the authentication unit 103 executes authentication that requires displaying a screen other than the input screen SC1 and is necessary for the procedure performed from the input screen SC1. The authentication is not completed unless the other screen is displayed. The procedure performed from the input screen SC1 is not completed unless the authentication is successful. Successful authentication means that the legitimacy of the user is proven.

The other screen is a screen displayed using a window, a tab, or an application other than the input screen SC1. In this embodiment, the mail screen SC2 corresponds to the other screen. Therefore, the description of the mail screen SC2 can be read as the other screen. The other screen may be a screen other than the input screen SC1, and is not limited to the mail screen SC2. For example, when SMS authentication is performed instead of mail authentication, a screen for displaying a short message corresponds to the other screen. For example, when incoming call authentication or outgoing call authentication is performed, a screen for answering or speaking a phone call corresponds to the other screen. Note that the server 10 may be involved in the display of the other screen, but in this embodiment, the server 10 is not involved in the display of the other screen. For example, the other screen may be displayed by the user terminal 20 communicating with another server computer (e.g., a mail server) other than the server 10, or may be displayed only by internal processing of the user terminal 20 without communication by the user terminal 20.

The procedure carried out from input screen SC1 is a procedure that progresses or is completed by inputting input information on input screen SC1. In this embodiment, a case will be described in which applying for a payment service corresponds to a procedure carried out from input screen SC1. Therefore, the section describing applying for a payment service can be read as a procedure carried out from input screen SC1. Any procedure is possible on input screen SC1, and is not limited to applying for a payment service to register as an affiliated store.

For example, an application by an end user who makes a payment through a payment service, rather than a store that receives payment through a payment service, may correspond to the procedure carried out through input screen SC1. An application for a service other than a payment service may correspond to the procedure carried out through input screen SC1. For example, an application by a facility affiliated with a travel reservation service (e.g., a hotel, rental car store, tourist facility) or a store that operates an e-commerce service may correspond to the procedure carried out through input screen SC1.

For example, the other services may be financial services, communication services, video distribution services, ticket sales services, online flea market services, etc. Furthermore, the procedures carried out from the input screen SC1 are not limited to applying for a service. For example, the procedures may be a procedure for registering a comment on a news article, a procedure for purchasing a product in an electronic commerce service, a procedure for making a payment in a payment service, or a procedure for using a financial service.

For example, the authentication unit 103 sends a notification including authentication information required for authentication to a specified notification destination. The notification destination is the destination of the notification. The authentication information is information for proving legitimacy. The notification is an electronic message. In this embodiment, the user's email address corresponds to the notification destination, the link L corresponds to the authentication information, and the email corresponds to the notification. Therefore, the places where email address, link L, and email are written can be read as notification destination, authentication information, and notification, respectively.

As mentioned above, authentication using notifications is not limited to email authentication. The notification destination, authentication information, and notification may be the same as those used for authentication other than email authentication. For example, in SMS authentication, the phone number corresponds to the notification destination, the link L included in the short message corresponds to the authentication information, and the short message corresponds to the notification. For example, in authentication using a message app, the message app account corresponds to the notification destination, the link L included in the message app message corresponds to the authentication information, and the message app message corresponds to the notification.

In this embodiment, the authentication unit 103 sends an email including a link L to the user's email address entered as input information on the input screen SC1. For example, the authentication unit 103 hashes the user's session ID based on a hash function and generates the link L by incorporating the hashed session ID as an argument into the URL of the input screen SC1. The hashed session ID is stored in the storage database DB. The authentication unit 103 hashes the session ID, which is the first argument of the arguments of the URL of the input screen SC1, and includes it in the link L, but does not include the second argument in the link L. The authentication unit 103 generates an email by including the link L in a fixed-phrase email, and sends it to the user's email address.

For example, the email screen SC2 displays an email sent by the authentication unit 103. The authentication unit 103 performs authentication based on the URL of the link L received from the user terminal 20 that has displayed the email screen SC2. The authentication unit 103 determines whether the hashed session ID included as an argument in the URL received from the user terminal 20 exists in the saved database DB. If it is determined that the hashed session ID exists in the saved database DB, the authentication unit 103 determines that the authentication is successful. If the authentication is successful, the authentication unit 103 changes the value of the authenticated flag. This change in value causes the authentication window W2 to disappear.

For example, the authentication unit 103 determines that the authentication has failed if it is determined that the hashed session ID does not exist in the storage database DB. In this embodiment, a match of the hashed session ID is a condition for successful authentication, but a match of the session ID transmitted by the user terminal 20 during communication is not a condition for successful authentication. Both a match of the hashed session ID and a match of the session ID transmitted by the user terminal 20 during communication may be conditions for successful authentication.

In this embodiment, the user terminal 20 that displays the input screen SC1 before authentication and the user terminal 20 that displays the mail screen SC2 are the same, but they may be different. For example, the input screen SC1 before authentication may be displayed on the user's personal computer (first user terminal 20), and the mail screen SC2 may be displayed on the user's smartphone (second user terminal 20). In this case, after completing authentication on the smartphone, the user may continue to input data from the smartphone, or may continue to input data from the personal computer that originally had the input screen SC1 open.

[Display control unit]
The display control unit 104 displays the input screen SC1. In this embodiment, since the display control unit 104 is realized by the server 10, the display control unit 104 generates display data for the input screen SC1 including the input information, and transmits the generated display data to the user terminal 20 to display the input screen SC1. In this embodiment, a case will be described in which the display control unit 104 displays both the input screen SC1 before authentication and the input screen SC1 after authentication, but the display control unit 104 may display only one of them. In this case, a function for displaying the other screen will be present separately from the display control unit 104.

In this embodiment, when authentication is completed, the authentication unit 103 displays the input screen SC1 based on the input information stored by the storage unit 101. When authentication is completed, it means after authentication is completed. Some screen may be displayed between the completion of authentication and the display of the input screen SC1. It is sufficient that the input screen SC1 based on the input information stored by the storage unit 101 is displayed at some point after authentication is completed, and the display of some screen (for example, a screen indicating that authentication is completed) may be inserted in between, or may not be inserted. For example, the display control unit 104 displays the input screen SC1 based on the input information associated with the session ID (in this embodiment, a hashed session ID) received from the user terminal 20 that has executed the authentication. The authentication unit 103 obtains the input information associated with the session ID from the storage database DB and sets it in the input form F of the screen SC1. The authentication unit 103 displays the input screen SC1 including the input form F in which the input information is set. The authentication unit 103 displays the input screen SC1 in the same state as immediately before the authentication was completed, based on the input information stored in the saved database DB.

In this embodiment, since second input information can be input after authentication in addition to the first input information input before authentication, the display control unit 104 displays an input screen SC1 that accepts input of second input information different from the first input information based on the first input information. For example, the display control unit 104 displays the input screen SC1 in a second tab T2 different from the first tab T1, or in a second window different from the browser window W1 (first window).

In this embodiment, the display control unit 104 displays an authentication window W2 for receiving an authentication start operation so as to be superimposed on the input screen SC1, and when the input screen SC1 is scrolled, the display control unit 104 makes the authentication window W2 follow the input screen SC1. Since the movement of the authentication window W2 itself is executed by the user terminal 20, the display control unit 104 makes the authentication window W2 follow the input screen SC1 by transmitting to the user terminal 20 display data of the input screen SC1 including a script for making the authentication window W2 follow the input screen SC1.

In this embodiment, not only the input information but also the display portion information is stored, so the display control unit 104 displays the input screen SC1 based on the input information and display portion information stored by the storage unit 101. For example, the display control unit 104 refers to the storage database DB and acquires the display portion information associated with the session ID (in this embodiment, a hashed session ID) received from the user terminal 20. This display portion information indicates the currently displayed page among the multiple pages included in the input screen SC1. The display control unit 104 displays the page among the multiple pages indicated by the display portion information stored by the storage unit 101. It is assumed that data (e.g., HTML data) for displaying each page is pre-recorded in the data storage unit 100.

[Application Reception Department]
The application acceptance unit 105 accepts the application after the input screen SC1 is displayed by the display control unit 104. The input screen SC1 accepts input of information necessary for application for the service, and the application acceptance unit 105 completes the application based on the various input information. Completing the application means storing the input information entered by the user in a database for users who have completed their application. When the application acceptance unit 105 receives a page transition request to the "Complete" page, it accepts the application on the condition that authentication is completed and all input information has been completed. If authentication is not completed or if there is any required input information that has not been entered, the application is not completed.

[3-2. Functions realized by user terminal]
The user terminal 20 includes a data storage unit 200, a display control unit 201, and an operation reception unit 202. The data storage unit 200 is realized by the storage unit 22. The display control unit 201 and the operation reception unit 202 are realized by the control unit 21.

[Data storage section]
The data storage unit 200 stores data necessary for applying for a payment service. For example, the data storage unit 200 stores a browser, a session ID, and display data of the input screen SC1.

[Display control unit]
The display control unit 201 displays various screens on the display unit 25. For example, the display control unit 201 displays an input screen SC1 and a mail screen SC2. The display control unit 201 executes a script included in the display data of the input screen SC1, and controls the display of the input screen SC1 and the authentication window W2.

[Operation reception section]
The operation reception unit 202 receives various operations performed from the operation unit 24. For example, the operation reception unit 202 receives operations on each of the input screen SC1 and the mail screen SC2. The operation contents received by the operation reception unit 202 are transmitted to the server 10.

[4. Processing Executed in the Display Control System]
9 and 10 are diagrams showing an example of processing executed by the display control system 1. The processing in Fig. 9 and Fig. 10 is executed by the control units 11 and 21 operating in accordance with programs stored in the storage units 12 and 22, respectively.

As shown in FIG. 9, when a user performs an operation to display input screen SC1, the user terminal 20 sends a display request for input screen SC1 to the server 10 (S1). The display request is data in a predetermined format for displaying input screen SC1. The display request includes the URL of input screen SC1. When the user terminal 20 receives the display request for input screen SC1, it establishes a session with the server 10 (S2).

In S2, the server 10 issues a session ID and calculates a certain period of time from the current time as the expiration date. The server 10 stores the issued session ID, an authentication flag with a first value indicating no authentication, and the expiration date in the storage database DB in association with each other. The server 10 transmits the session ID and display data of the input screen SC1 to the user terminal 20 (S3). The display data of the input screen SC1 also includes data for displaying the authentication window W2.

When the user terminal 20 receives the session ID and the display data, it records the session ID in the storage unit 22 and displays the input screen SC1 on the display unit 25 (S4). The input screen SC1 in S4 is in the state shown in FIG. 2. The session ID is stored in the browser's cookie. Thereafter, when the user terminal 20 communicates with the server 10, the session ID stored in the cookie is transmitted.

The user terminal 20 identifies the user's operation based on the detection signal of the operation unit 24 (S5). In S5, an input operation for inputting input information, a scroll operation for scrolling the input screen SC1, an authentication start operation for starting authentication, a display operation for displaying the mail screen SC2, or a page transition operation for transitioning to the next page is performed. When an operation such as closing the input screen SC1 is performed, a process corresponding to the operation is executed.

In S5, when an input operation is performed (S5: input operation), the user terminal 20 displays the input information entered by the input operation on the input screen SC1 (S6). The user terminal 20 transmits the input information together with the session ID to the server 10 (S7). When the server 10 receives the session ID and the input information, it associates them and stores them in the storage database DB (S8).

When a scroll operation is performed in S5 (S5: scroll operation), the user terminal 20 scrolls the input screen SC1 (S9). In S9, the user terminal 20 controls the display of the authentication window W2 so that it moves together with the scrolling of the input screen SC1. In this embodiment, the user terminal 20 controls the display of the authentication window W2 by executing a script included in the display data of the input screen SC1. The script includes a command to move the authentication window W2 within the input screen SC1 when a scroll operation is performed.

The process of controlling the display of the authentication window W2 may be executed by the server 10. In this case, the display position of the authentication window W2 is calculated by the server 10, and the user terminal 20 receives the display position of the authentication window W2 from the server 10 and moves the authentication window W2. When the authentication window W2 is displayed as a pop-up separated from the input screen SC1, the user terminal 20 simply needs to prevent the display position of the authentication window W2 from changing, and therefore no special process of controlling the display of the authentication window W2 is executed.

When an authentication start operation is performed in S5 (S5: authentication start operation), the user terminal 20 transmits an authentication start request to the server 10 (S10). When the server 10 receives the authentication start request, it transmits an authentication e-mail to the user's e-mail address (S11). In S11, the server 10 calculates an argument by hashing the session ID based on a hash function. The server 10 generates and transmits an e-mail including the URL of the input screen SC1 and the calculated argument as a link L. Note that if the user has not input an e-mail address, the authentication start operation may not be accepted, or the process of S10 may not be executed and an error may occur.

When a display operation is performed in S5 (S5: display operation), the user terminal 20 displays the mail screen SC2 on the display unit 25 (S12). Here, it is assumed that the email sent in S11 is displayed on the mail screen SC2. Moving to FIG. 10, when the user selects the link L, the user terminal 20 transmits an authentication completion request to the server 10 (S13).

When the server 10 receives the authentication completion request, it executes the authentication and updates the authenticated flag in the saved database DB (S14). If the authentication fails, the authenticated flag is not updated and an error message is displayed on the user terminal 20. The server 10 generates display data for the input screen SC1 based on the input information in the saved database DB and transmits it to the user terminal 20 (S15). When the user terminal 20 receives the display data for the input screen SC1, it displays the input screen SC1 on the second tab T2 (S16) and returns to the processing of S5. However, since the authentication is complete, the authentication window W2 is not displayed and the authentication start operation is not accepted.

When a page transition operation is performed in S5 (S5: page transition operation), the user terminal 20 transmits a page transition request to the server 10 (S17). When the server 10 receives the page transition request, it determines whether or not the transition is to the final page (S18). When it is determined that the transition is not to the final page (S18: N), the server 10 updates the display portion information (S19) and transmits display data of the page after the transition to the user terminal 20 (S20).

If it is determined in S18 that the page has been transitioned to the final page (S18: Y), the server 10 determines whether or not authentication has been completed based on the authenticated flag (S21). If it is determined that authentication has not been completed (S21: N), the server 10 causes the user terminal 20 to display an error message (S22). The user terminal 20 displays the error message and returns to the processing of S5. If it is determined in S20 that authentication has been completed (S21: Y), the server 10 executes processing to complete the application (S23), and this processing ends.

In the display control system 1 of the present embodiment, when authentication is completed, the input screen SC1 is displayed based on the input information stored by the storage unit 101. Since authentication requires the display of a mail screen SC2 different from the input screen SC1, the user may mistakenly close the input screen SC1 that was open until then. In this case, the input screen SC1 based on the input information that was input until then is displayed, and it is possible to avoid starting over from the beginning, thereby improving user convenience. Even if the user does not close the input screen SC1, if the screen on which authentication is completed is displayed in a tab or window other than the first tab T1, the user must return to the first tab T1 to continue the input operation, but since the input operation can be continued on the input screen SC1 that is displayed when authentication is completed, this also improves user convenience. Furthermore, by improving user convenience, it is possible to prevent the user from stopping input midway, thereby reducing the drop rate of the user. For example, since the user can start authentication at any time they like, even if the user is not in an environment where he or she can immediately check e-mail, it is possible to perform authentication with a high degree of freedom, such as inputting input information halfway and executing authentication at any time after a certain amount of time has passed. With conventional methods, users who are not in an environment where they can check their e-mail immediately may give up midway through input, but highly flexible authentication can reduce the rate at which users drop out. For example, a user who has entered a certain amount of information may feel that it would be a waste to abandon the process, since they have already taken the time to enter their information, even if they find authentication troublesome. In this case, the likelihood of the user completing the input increases. For example, an effect similar to the sunk cost effect can be achieved.

Furthermore, the display control system 1 saves the first input information input to the input screen SC1, and displays the input screen SC1 that accepts input of second input information different from the first input information based on the first input information. This allows authentication to be performed midway through the user's input, rather than after the user has completed all input, improving user convenience. For example, the user can perform authentication when a certain amount of input has been completed, and then continue inputting after that. By improving user convenience, it is also possible to prevent users from abandoning input midway. As a result, by improving user convenience, it is possible to prevent users from abandoning input midway, thereby reducing the user dropout rate.

The display control system 1 also displays the input screen SC1 in a second tab T2 different from the first tab T1, or in another window different from the browser window W1. This allows the input screen SC1 to be displayed in a new location, improving user convenience.

The authentication start operation can be performed from any of the multiple pages included in the input screen SC1. This allows the user to start authentication from any page, improving user convenience.

The display control system 1 also displays an authentication window W2 for accepting an authentication start operation so as to be superimposed on the input screen SC1, and when the input screen SC1 is scrolled, the authentication window W2 follows it. This makes it easier for the user to notice that authentication is required. Furthermore, when the user wants to start authentication, the authentication window W2 can be immediately confirmed, improving user convenience.

The display control system 1 also displays the input screen SC1 based on the input information and display portion information stored by the storage unit 101. This allows the input screen SC1 to be displayed from the portion that the user had displayed until immediately before authentication, improving user convenience.

The display control system 1 also displays, among the multiple pages, the page indicated by the display portion information stored by the storage unit 101. This allows the input screen SC1 to be displayed from the page that was displayed immediately before authentication when the user inputs data while moving between pages, improving user convenience.

The server 10 also associates the session ID and the input information and stores them in the storage database DB. The display control system 1 displays the input screen SC1 based on the input information associated with the session ID received from the user terminal 20 that has executed the authentication. This makes it possible to more reliably display the input screen SC1 based on the input information stored by the storage unit 101. For example, it is possible to store the input information in a cookie on the user terminal 20, but if the user accidentally closes the browser window W1, the input information stored in the cookie may be lost. In this regard, by having the server 10 store the input information, it is possible to display the input screen SC1 based on the input information stored by the storage unit 101 even if the user accidentally closes the browser window W1.

The display control system 1 also sends an email containing the URL indicated by the link L to the user's email address. The display control system 1 performs authentication based on the URL received from the user terminal 20 that has displayed the email screen SC2. This allows authentication to be completed with simple operations, improving user convenience. Furthermore, it is possible to more reliably prevent impersonation by a third party.

In addition, the display control system 1 accepts the application after the input screen SC1 is displayed. This improves user convenience when applying.

5. Modifications
The present disclosure is not limited to the above-described embodiment, and may be modified as appropriate without departing from the spirit and scope of the present disclosure.

[5-1. Modification 1]
For example, in the embodiment, a case has been described in which input to the input screen SC1 is accepted even after the authentication start operation has been performed. As described in the embodiment, if input information is transmitted to the server 10 in real time, even if input information is input between the authentication start operation being performed and the link L being selected, the input information can be reflected in the input screen SC1 after authentication. In the first modified example, as another method, a case in which input to the input screen SC1 is restricted when the authentication start operation is performed will be described.

FIG. 11 is a diagram showing an example of a function realized in the first modified example. The display control system 1 includes a restriction unit 106. The restriction unit 106 is realized by the control unit 11. When it is determined that an authentication start operation has been performed, the restriction unit 106 restricts input to the input screen SC1. In the first modified example, a case is described in which setting the input form F to the disable attribute corresponds to restricting input, but erasing the input form F may also correspond to restricting input. For example, when it is determined that an authentication start operation has been performed, the restriction unit 106 transmits a request to the user terminal 20 indicating that the input form F should be set to the disable attribute.

When the user terminal 20 receives the request, it changes the attribute of input form F to "disable". When the restriction unit 106 is realized by the user terminal 20, the restriction unit 106 executes a script included in the display data of the input screen SC1 and changes the attribute of input form F to "disable". In this case, the user terminal 20 can restrict input to input form F without receiving a request from the server 10. When deleting input form F, the same process can be followed to delete input form F.

When authentication is complete, the display control unit 104 displays the input screen SC1 with the restrictions imposed by the restriction unit 106 lifted based on the input information stored by the storage unit 101. Lifting the restrictions means setting the input form F to the enable attribute or displaying the input form F. The process of displaying this input screen SC1 is the same as in the embodiment.

The display control system 1 of the first modified example restricts input to the input screen SC1 when it is determined that an authentication start operation has been performed. When authentication is completed, the display control system 1 displays the input screen SC1 from which the restriction by the restriction unit 106 has been lifted, based on the input information stored by the storage unit 101. This prevents input information entered after the authentication start operation has been performed from going to waste, thereby improving user convenience.

[5-2. Modification 2]
For example, if a user inputs an incorrect email address, an email containing the link L may be sent to a third party. In this case, if the third party selects the link L in the email, the third party will be able to view the input information that the user has input up to that point. Therefore, the display of the input information may be restricted on the input screen SC1 after the link L is selected so that the input information cannot be viewed by the third party.

When authentication is completed, the display control unit 104 of the second modified example may display an input screen SC1 that has been processed to restrict the display of the input information stored by the storage unit 101. Restricting the display of the input information means blacking out the input information, not displaying the input information, or encrypting the input information. A password may be set to display the input information whose display has been restricted again.

When authentication is completed, the display control system 1 of the second modified example displays an input screen SC1 that has been modified to restrict the display of the input information stored in the storage unit 101. This makes it possible to prevent a third party from viewing the input information entered by the user.

[5-3. Modification 3]
For example, the display control system 1 may not include some of the functions described in the embodiment. The present disclosure can solve problems other than the problem of improving user convenience by displaying the input screen SC1 based on the input information stored in the storage unit 101. For example, it can solve other problems such as improving user convenience by making the authentication window W2 follow the input screen SC1 when the input screen SC1 is scrolled. Therefore, the scope of the present disclosure also includes a case where the display control system 1 does not include a configuration for displaying the input screen SC1 based on the input information that has already been input when authentication is completed.

For example, the display control system 1 may not include the storage unit 101, but may include only the determination unit 102, the authentication unit 103, and a configuration of the display control unit 104 that causes the authentication window W2 to follow when the input screen SC1 is scrolled. The display control system 1 of the modification example 3 causes the authentication window W2 for starting authentication at any timing to follow when the input screen SC1 is scrolled, thereby eliminating the need for the user to search for an image for performing the authentication start operation, thereby solving problems other than those described in the embodiment. This disclosure also supports such a configuration.

[5-4. Other Modifications]
For example, the above-described modifications may be combined.

For example, in the embodiment, a case has been described in which a store considering joining the payment service corresponds to a user, but a person who makes a payment using the payment service (a so-called end user) may also correspond to a user. The display control system 1 may be applied when this person registers as a member for the payment service. The display control system 1 is also applicable to other services described in the embodiment, so the display control system 1 may be applied when registering as a member for services other than the payment service.

For example, in the embodiment, the server 10 stores the input information, but the user terminal 20 may store the input information. For example, the user terminal 20 stores the input information in a browser cookie or in another location (a memory area other than the browser). When the user selects the link L, the user terminal 20 may display an input screen SC1 that carries over the input information that was entered up until immediately before authentication, based on the input information stored in the user terminal 20.

For example, an expiration date may be set for the link L. When an authentication start operation is performed, the authentication unit 103 stores the expiration date of the link L in the storage database DB. The expiration date is a fixed time after the authentication start operation is accepted. The length of the expiration date may be any length. Even if the user selects an expired link L, authentication is not completed. When the link L expires, the user must perform the authentication start operation again. In this case, a new expiration date is set.

For example, if the user re-enters an email address after an authentication email has been sent, the link L included in the sent email may become invalid. Each time a new link L is generated, the authentication unit 103 invalidates the old link L. For example, the authentication unit 103 may delete the hashed session ID included in the old link L from the storage database DB, or may store a flag indicating that the hashed session ID is invalid in the storage database DB. The hashed session ID changes each time an email is resent.

For example, the display control unit 104 may display the input screen SC1, which carries over the input information previously input, only when there is access from a user terminal 20 in which the hashed session ID included in the link L is saved. In other words, in addition to the selection of the link L, a match of the session ID (not hashed) may also be a condition for carrying over the input information.

For example, the functions described as being realized by the server 10 may be shared among multiple computers. The functions described as being realized by the server 10 may be realized by the user terminal 20. For example, the main processing related to the display of the input screen SC1 may be executed by the user terminal 20, rather than by the server 10. In this case, the display control unit 201 of the user terminal 20 may have the same functions as the display control unit 104 of the server 10 described in the embodiment. However, since the display control unit 201 does not need to transmit display data to the outside like the display control unit 104, it is sufficient to process the display data generated by the display control unit 201 itself or the display data received from the server 10 and display it on the display unit 25.

For example, the functions described as being realized by the server 10 or the user terminal 20 may be realized by at least one computer in the display control system 1, or the functions may be shared among multiple computers. In this case, each of the multiple computers may transmit its own processing results to the other computers, thereby sharing the functions.
