Description

TECHNICAL FIELD The present invention relates to an information display system, and more particularly to an information display system suitable for limiting the display of information such as tickets and documents to specific individuals.

Patent Literature 1 discloses a system for issuing tickets with facial photographs. At an event venue or the like, it may be necessary to verify the identity of the ticket holder. According to the ticket described in Patent Literature 1, the event staff can visually confirm the identity based on the face photo printed on the ticket.

A photograph printed on a ticket may become difficult to see due to damage or dirt. In Patent Document 1, in preparation for such a situation, when selling a ticket printed with a face photograph, the face data is stored in a server at the head office. When it is difficult to confirm the identity of the person due to damage or dirt on the ticket at an event venue, etc., the face data registered on the ticket is read out on a display installed at the venue, and the identity is confirmed based on the display.

As described above, according to the system described in Patent Document 1, it is possible to reliably confirm the identity of the ticket holder at an event venue or the like by visual inspection by the staff.

Japanese Patent Application Laid-Open No. 2004-259134

However, in the system described in Patent Literature 1, the event staff must visually confirm the identity of the person at the event venue. Visual judgment requires a certain amount of time and is accompanied by a certain amount of misunderstanding. Furthermore, such identity verification inevitably places a heavy burden on event staff. On the other hand, if we build a system that allows only the person to display the ticket on the display, it will be possible to easily and reliably confirm the person's identity simply by checking whether the ticket is displayed at the event venue. .

a process of canceling registration of at least one of the registered display information and the registered biometric information when the cancellation condition is satisfied;
A process of reflecting the cancellation state on the terminal;
is further configured to perform

According to the first invention, the storage device of the server stores the registered display information and the registered biometric information. When the user requests display of the registration display information via the input interface of the terminal, the processing unit accepts user input specifying the operating user together with the acquired biometric information acquired at that time. Further, the processing unit performs personal authentication based on whether or not the received acquired biometric information matches the registered biometric information related to the operating user. If the two match, the operating user is authenticated as the user associated with the registered display information, and display of the registered display information is permitted. Therefore, according to the present invention, the registered display information can be displayed on the display of the terminal only when the personal authentication based on the registered biometric information is cleared.

According to the second invention, personal authentication is performed based on whether or not the face information registered in the server matches the face information acquired by the terminal. Face information can be easily acquired by a camera. In addition, if it is face information, the user is unlikely to feel resistance to submitting it as registered biometric information. Therefore, according to the present invention, it is possible to provide a highly convenient information display system.

According to the third invention, the processing of personal authentication is performed by the processing unit provided in the server. The processing unit can receive the acquired biometric information necessary for personal authentication from the terminal. As described above, according to the present invention, it is possible to properly authenticate the user under the condition that communication can be performed between the server and the terminal without imposing a processing load on the terminal.

According to the fourth invention, the personal authentication process is performed by the processing unit provided in the terminal. The terminal can receive and store registered biometric information required for personal authentication and registered display information required for display from the server. Therefore, the terminal can appropriately perform the personal authentication process and the information display process without communicating with the server when the display of the registration display information is requested.

According to the fifth invention, the registered biometric information is registered in the server at the time of user registration. Also, the registration display information is registered in the server when the registration is requested by the user. Then, the registered biometric information and the registered display information are provided to the terminal at the latest when the registration display information is registered. Therefore, according to the present invention, it is possible to store in the terminal all materials necessary for the personal authentication process and the information display process before the display of the registration display information is requested by the user.

According to the sixth aspect, both the registered biometric information and the registered display information are registered in the server when the user requests registration of the registered display information. Both of which are then provided to the terminal during its registration. For this reason, according to the present invention, as in the case of the fifth invention, before the display of the registration display information is requested by the user, all materials necessary for the personal authentication process and the information display process are sent to the terminal. can be stored in .

According to the seventh invention, the ticket information is registered as the registered display information, and the ticket information can be displayed on the display of the terminal only when the personal authentication is cleared. Therefore, according to the present invention, it is possible to very easily complete the identity verification work simply by confirming whether or not the ticket information is displayed on the display of the terminal.

According to the eighth aspect, during personal authentication, the variable information is displayed together with the ticket information on the display of the terminal. Since the variable information changes over time, the correct variable information at the time of personal authentication is not displayed until that time. In other words, the screen obtained by capturing the content displayed in advance is different from the correct screen at the time of personal authentication. Therefore, according to the present invention, it is possible to easily prevent a person from bypassing personal authentication using a capture screen.

According to the ninth invention, if the cancellation condition of the ticket is satisfied, the registration of at least one of the registered display information and the registered biometric information is canceled, and the state is reflected on the terminal. When the registration of the registered display information is cancelled, the ticket information is no longer displayed on the terminal of the user who was the registrant. Further, if the registration of the registered biometric information is canceled, the user who was the registrant cannot clear the personal authentication any longer. Therefore, it is possible to prevent unauthorized use of the ticket information by the original registrant. By registering the canceled ticket with another user, the ticket can be used effectively without relying on individual trading between users.

Embodiment 1.
[Configuration of Embodiment 1]
FIG. 1 is a diagram for explaining an outline of an information display system according to Embodiment 1 of the present invention. The information display system of this embodiment includes a management server 10 . A management server 10 is connected to a plurality of terminals 14 and 16 via a network 12 . Terminals 14 and 16 represent a smart phone and a tablet, respectively.

The information display system of the present embodiment assumes that ticket information is displayed on the terminals 14 and 16 of users who have cleared personal authentication at the event site. Therefore, in this embodiment, the terminals 14 and 16 are smartphones and tablets, which are mobile terminals. However, since the ticket information can also be displayed on an installation-type display placed at the event venue, the terminal of the present embodiment may include a personal computer or the like.

The server 10 and terminals 14, 16 each have a general configuration. FIG. 2 shows the hardware configuration of the server 10. As shown in FIG. As shown in FIG. 2, terminal 14 includes a central processing unit (CPU) 18 . Storage devices such as a ROM 22 , a RAM 24 and a storage 26 are connected to the CPU 18 via a communication bus 20 . A communication interface 28 , an input interface 30 and a display 32 are also connected to the communication bus 20 .

A program executed by the CPU 18 is stored in the ROM 22 of the management server 10 . In addition, in the storage 26 of the management server 10, account information of users registered as users in this system, biometric information and display information registered in relation to individual users (hereinafter referred to as "registered biometric information") and "registered display information") are stored.

Biometric information that can be used in this embodiment includes all biometric information that can be used for individual identification, such as face information, fingerprint information, voiceprint information, iris information, and vein information. In this embodiment, face information is used as biometric information because it is easy to acquire and manage. The display information used in this embodiment includes information to be included in the event ticket (hereinafter referred to as “ticket information”) and variable information that changes over time. The ticket information includes, for example, the date and time of the event, venue, seat type, price, number of tickets, and the like. The variable information includes a countdown display that displays the number of days until the date of the event, an embedded display that changes color and shape according to the time until the date and time of the event, and the like.

Terminals 14 and 16 also have a configuration generally similar to that shown in FIG. However, in the case of the terminals 14 and 16, the input interface (30) includes a touch panel built into the display (32) and a camera. In this embodiment, the camera functions as a biometric information acquisition device for acquiring face information, which is biometric information. When information different from face information, such as fingerprint information, is used as biometric information, a sensor or the like suitable for the biometric information to be acquired can be used as the biometric information acquisition device.

[Features of Embodiment 1]
The features of the information display system of this embodiment will be described below with reference to FIGS. 3 to 6. FIG. FIG. 3 is a flowchart for explaining the flow of user registration. The information display system of this embodiment first requests user registration from a user who wishes to use it.

A user who intends to register as a user uses the terminal 14 to enter account information such as an ID and a password. The entered account information is sent to the server 10 (step 100).

The server 10 that has received the account information associates them with individual users and stores them in the storage 26 (step 102).

In the system of the present embodiment, registration of face information as biometric information used for personal authentication is required at the time of user registration. In response to this request, the user requesting user registration takes a picture of his or her face or moving image with the camera of the terminal 14, and transmits the resulting face information to the server 10 (step 104). Personal authentication using face information is not performed based on the face image or face moving image itself, but is performed based on comparison of facial feature data. Therefore, the face information transmitted in step 104 may be a face image or a face moving image itself, or may be information of facial feature data extracted from an image or moving image.

Upon receiving the face information, server 100 associates the face information with the user's ID and stores it in storage 26 as registered face information (step 106). The above processing completes the user registration processing.

FIG. 4 is a flowchart for explaining the flow when a user purchases a ticket. In this scene, the user enters ticket purchase information into the terminal 14 after logging in to the system by entering an ID, password, and the like. The ticket purchase information includes information such as the name of the event, the date and time of the event, the type of seat, the required number of tickets, and the payment method for specifying the ticket to be purchased. The entered ticket purchase information is transmitted to the server 10 (step 108).

When the server 100 receives the ticket purchase information and secures the ticket specified by the ticket purchase information, it registers the ticket in association with the ID of the user who made the purchase (step 110). Since only one ID can be registered for one ticket, tickets associated with this user's ID will not be sold to other users thereafter.

When the ticket registration to the ID is finished, the server 10 sends a message to the effect that the ticket has been secured, the display information of the ticket, and the registered face information of the user who is the purchaser to the terminal 14 (step 112). . The display information of the ticket includes information (event name, date and time, venue, opening time, start time, seat type, number of tickets, fee, etc.) and variable information for fulfilling the ticket function. The variable information includes display information such as characters, colors, and shapes that change with the passage of time, such as a countdown display until the date of the event.

The terminal 14 that has received the above transmission displays a purchase completion message on the display (32), and stores the received ticket information and registered face information in the storage (26) in a state in which they are linked (step 114). With the above processing, the ticket purchase processing is completed.

FIG. 5 is a flowchart for explaining the flow of ticket presentation at the event site. A user who has purchased a ticket brings the terminal 14 in which the ticket information is stored to the event site. The display (32) of the terminal 14 displays a list of all tickets stored in the terminal 14 associated with the user's ID in response to a request from the operating user. When asked to present a ticket at the event venue, the user first selects the ticket to be displayed from the list on the display (32) (step 116).

When the ticket to be displayed is selected, the terminal 14 requests the user to take a picture of his/her face with the camera. Then, when the user takes a face image or a face moving image according to the instruction, the terminal 14 acquires face information based on the photographed result (step 118). Hereinafter, the face information captured here will be referred to as "acquired face information".

The terminal 14 then performs face authentication based on the obtained face information (step 120). Specifically, the degree of correlation between the facial feature data included in the acquired facial information and the facial feature data included in the registered facial information stored in association with the selected ticket is calculated.

Then, it is determined whether or not the user who provided the obtained face information matches the user who provided the registered face information based on whether or not the degree of correlation exceeds a preset threshold value ( step 122).

If it is determined that the two match, it can be determined that the user who is about to present the ticket is the rightful owner of the ticket at the event venue. In this case, the terminal 14 displays the ticket information on the display (32) assuming that the personal authentication has been cleared (step 124).

On the other hand, if it is determined that the two do not match, it can be determined that the user who is about to present the ticket is not the person who purchased the ticket. In this case, the personal authentication is denied, and the terminal 14 displays authentication NG on the display (32) (step 126).

As described above, according to the system of the present embodiment, only users whose personal authentication has been cleared can display ticket information on the display (32) of the terminal 14 at the event site. Therefore, the event staff who manages the entrance can very easily determine whether the terminal 14 holder is a genuine ticket holder simply by confirming whether the ticket information is displayed on the terminal 14. , and can be determined accurately.

Further, as shown in FIG. 5, in the system of this embodiment, the server 10 is not required to perform any processing regarding ticket presentation at the event site. That is, the series of processes shown in FIG. 5 can be completed by the terminal 14 alone without requiring communication with the server 10 . Therefore, according to the system of this embodiment, there is no need to consider risks such as network failures and communication failures due to access concentration, and stable performance can always be obtained.

Ticket-related fraud may include, for example, illegal resale of tickets. In a mode in which an account and an electronic ticket are linked, there have been cases where the ticket is illegally resold along with the account. According to the system of the present embodiment, if one individual who purchased the ticket transfers the ticket together with the account to another individual, the other individual cannot clear face authentication at the event venue. Therefore, according to the system of this embodiment, it is possible to effectively prevent fraud in such a manner.

Another example of ticket-related fraud is the change of visitors under the guise of re-entry. If the visitors are replaced, it will not be possible to clear the face recognition. For this reason, if a series of processes from capturing the obtained face information to presenting the ticket are executed in front of the event staff, the system of the present embodiment can effectively prevent fraud in such a manner. can.

FIG. 6 shows an example of display information displayed on the terminal 14 when face authentication is cleared. This display information includes ticket information 34 and countdown display 36 . The countdown display 36 is configured to change its display in cooperation with the clock function of the terminal 14, for example. As fraud related to tickets, the purchaser of the ticket calls the display information as shown in FIG. can be considered.

However, for example, according to the example shown in FIG. 6, it is not possible to obtain display information in which the countdown display 36 becomes "Day 0" until the day of the event. In the genuine display information for the day of the event, the countdown display 36 should be "Day 0". In this case, if you try to cheat using the captured screen, you will have to capture a screenshot on the day of the event and hand over the image to the assignee.

Furthermore, the countdown display 36 shown in FIG. 6 is merely an example of variable information, and the variable information may include an embedded display that changes in units of hours or minutes instead of units of day. As a result, if the displayed information changes by the hour or by the minute, it is virtually impossible to prepare a genuine capture screen in advance and hand it over to the transferee. Therefore, according to the system of this embodiment, it is possible to practically prevent illegal resale of tickets using captured images.

Furthermore, the time for which ticket information is displayed on the display (32) of the terminal 14 may be limited to 15 minutes or 30 minutes, and a timer indicating the remaining display time may be used as variable information. Additionally, the timer may have movement, such as a rolling motion, to indicate that it is running. In this case, a correctly displayed timer will always have some motion, whereas the captured image will not show such motion. Therefore, by checking whether the timer is operating normally at the event site, it is possible to effectively prevent unauthorized resale using the captured image. In addition, since the ticket information cannot be displayed continuously, it is possible to effectively prevent fraud such as renting out the entire terminal 14 .

[Modification of Embodiment 1]
FIG. 7 is a flow chart for explaining a modification of the first embodiment described above. FIG. 7, like FIG. 3, shows the flow of user registration. In FIG. 7, steps that are the same as those shown in FIG. 3 are denoted by common reference numerals, and description thereof will be omitted or simplified.

In the example shown in FIG. 7, after the registered face information is registered in the ID at step 106, the registered face information is transmitted from the server 10 to the terminal 14 (step 128). The terminal 14 then stores the received registered face information in the storage (26) at this stage (step 130).

In the first embodiment described above, the registered face information is transmitted to the terminal 14 together with the ticket-related information when the ticket is purchased. In this modified example, the transmission is completed at the time of user registration, and only the information related to the ticket is transmitted to the terminal 14 at the time of ticket purchase.

According to the procedure of this modified example, it is also possible to transfer the registered face information required for personal authentication and the ticket information required for ticket display to the terminal 14 prior to presenting the ticket at the event site. Therefore, according to this modified example, as in the case of the first embodiment, it is possible to proceed with personal authentication at the event site without relying on communication.

Further, according to this modification, since the registered face information is sent to the terminal 14 at the time of user registration, it is possible to save the trouble of sending the registered face information each time when purchasing a ticket. Therefore, according to this modified example, the overall processing load when a user purchases tickets repeatedly can be reduced compared to the case of the first embodiment.

By the way, in Embodiment 1 described above, event staff check tickets at the event site, but the present invention is not limited to this. Ticket confirmation may be performed not by event staff but by image processing using a camera.

Embodiment 2.
[Features of Embodiment 2]
An information display system according to a second embodiment of the present invention will be described below with reference to FIGS. 8 and 9. FIG. The system of this embodiment can be realized by a hardware configuration similar to that of the first embodiment (see FIGS. 1 and 2). This system differs from the system of Embodiment 1 in that the process of authenticating the person involved in presenting the ticket at the opening of the event is executed not at the terminal 14 but at the server 10 .

In this embodiment, the user registration process proceeds along the flowchart shown in FIG. 3, as in the case of the first embodiment.

FIG. 8 is a flowchart for explaining the processing that occurs when purchasing a ticket in this embodiment. In FIG. 8, steps that are the same as the steps shown in FIG. 4 described above are denoted by common reference numerals, and description thereof will be omitted or simplified.

In the flowchart shown in FIG. 8, when the ticket registration is finished in step 110, the server 10 transmits only a purchase completion message to the terminal 14 (step 132). At the time of ticket purchase, the terminal 14 does not receive information about the ticket, and only displays the purchase completion (step 134). In other words, in this embodiment, neither registered face information nor ticket information is transferred to the terminal 14 at the time of ticket purchase.

FIG. 9 is a flowchart for explaining the flow of processing associated with presenting a ticket at an event venue. Here, first, the user of the terminal 14 selects a ticket to be displayed on the terminal 14 . Information on the selected ticket is transmitted from the terminal 14 to the server 10 (step 136).

Upon receiving this information, the server 10 identifies the selected ticket from among the tickets registered in relation to the operating user of the terminal 14 (step 138).

The operating user of the terminal 14 is then requested to acquire and transmit face information. When the user receives this request and takes a picture of his/her face, the terminal 14 transmits the acquired face information to the server 10 (step 140).

Upon receiving the acquired face information (step 142), the server 10 performs face authentication processing based on the acquired face information (step 144). Here, as in step 120 shown in FIG. 5, the degree of correlation between acquired face information and registered face information related to the selected ticket is calculated.

If the degree of correlation exceeds the threshold, it is determined that the operating user of terminal 14 is a genuine ticket purchaser (step 146), and ticket information and variable information are transmitted from server 10 to terminal 14. (Step 148). On the other hand, if the above correlation is equal to or less than the threshold (step 146), the result of authentication NG is sent to the terminal 14 (step 150).

Upon receiving these transmissions, the terminal 14 displays the ticket information and variable information or the result of authentication NG on the display (32) (step 152).

As described above, the system of the present embodiment can display ticket information only on the terminal 14 of a user whose personal authentication has been cleared, as in the case of the first embodiment. Therefore, according to the system of this embodiment, it is possible to permit entry only to genuine ticket purchasers very easily and accurately.

In addition, in the system of the present embodiment, since ticket information and registered face information are not passed to the terminal 14, the risk of tampering with them can be eliminated. Furthermore, in the system of this embodiment, the only processing required of the terminal 14 is general-purpose processing such as information acquisition, transmission, reception, and display. can.

[First Modification of Embodiment 2]
In the second embodiment described above, the ticket information is not passed to the terminal 14 until the personal authentication is cleared. This modification differs from Embodiment 2 in that the ticket information itself is transmitted to the terminal 14 when the ticket is purchased. That is, in this modification, it is assumed that the ticket information is transmitted from the server 10 to the terminal 14 in the processing of steps 132 and 134 in the routine shown in FIG.

FIG. 10 is a flowchart for explaining the processing that occurs when a ticket is presented at the event venue in this modified example. In FIG. 10, steps that are the same as the steps shown in FIG. 9 described above are denoted by common reference numerals, and description thereof will be omitted or simplified.

According to the flowchart shown in FIG. 10, when the server 10 determines a match in step 146, it transmits a display permission signal to the terminal 14 (step 154). On the other hand, if a match is denied in step 146, server 10 transmits a display disapproval signal to terminal 14 (step 156).

When terminal 14 receives the above signal transmission (step 158), terminal 14 determines whether the signal is a grant signal (step 160). As a result, if it is an authorization signal, the ticket information stored in the storage (26) is displayed on the display (32). On the other hand, if the received signal is not the permission signal, the result of authentication NG is displayed on the display (32).

Thus, according to this modification, even if the ticket information is passed to the terminal 14 in advance, the same effect as in the case of the second embodiment can be obtained. In addition, according to the technique of this modification, since it is not necessary to communicate ticket-related information when presenting a ticket, the communication capability required for the event venue can be kept lower than in the case of the second embodiment. can be done.

[Second Modification of Second Embodiment]
In the second embodiment described above, the server 10 is caused to perform personal authentication, and the ticket information is not passed to the terminal 14 until the personal authentication is cleared. This modification differs from the second embodiment in that the ticket information is not passed to the terminal 14 until the personal authentication is cleared, but the personal authentication process itself is executed by the terminal 14 .

In this modification, in order to cause the terminal 14 to perform personal authentication processing when presenting a ticket at an event venue, registered face information is sent from the server 10 to the terminal 14 at the time of user registration or ticket purchase. sent. It is assumed that the terminal 14 stores the registered face information in the storage (26) when it is brought out to the event site.

FIG. 11 is a flowchart for explaining the processing that occurs when a ticket is presented at the event site in this modified example. In FIG. 11, steps that are the same as the steps shown in FIG. 5 described above are denoted by common reference numerals, and explanations thereof will be omitted or simplified.

According to the flowchart shown in FIG. 11, when the ticket is presented at the event site, the terminal 14 determines whether the face authentication matches (step 122). As a result, if no coincidence is obtained, the result of authentication NG is displayed on the display (32) (step 126).

On the other hand, if a match is determined, the terminal 14 issues a request for ticket information to the server 10 (step 162). Upon receiving this request, the server 10 transmits the ticket information to the terminal 14 (step 164). The terminal 14 that receives this displays the ticket information on the display (32) (step 166).

According to the above processing, ticket information can be displayed only on the terminal 14 of the user who has cleared the personal authentication, as in the case of the second embodiment. In addition, according to this modification, the processing associated with face authentication can be distributed to the terminal 14 without being concentrated on the server 10 . Furthermore, according to this modified example, since the ticket information is not passed to the terminal 14 in advance, the risk of tampering with the ticket information can be eliminated.

By the way, in Embodiments 1 and 2 described above, the display information handled by the system is limited to information related to tickets, but the present invention is not limited to this. For example, information that is permitted to be displayed only when personal authentication is cleared may be documents, spreadsheets, presentation materials, and the like. If such information is used as the display information of the present invention, it is possible to realize a system with a high security level in which even if the account information is leaked, only the person who registered the document can open the document. .

Embodiment 3.
Next, Embodiment 3 of the present invention will be described with reference to FIG. The functions of this embodiment described below can coexist with the functions of the above-described first or second embodiment or modifications thereof.

The information display system of this embodiment is characterized in that it has a function that enables ticket cancellation. FIG. 12 is a flowchart for explaining the processing for realizing ticket cancellation.

When the user wants to cancel the purchased ticket, after logging into the system, the user transmits a cancellation request from the terminal 14 to the server 10 (step 168).

When the server 10 receives the cancellation request (step 170), the server 10 performs processing to sell the ticket to be canceled (step 172). Note that this process may be replaced with a process of allocating a ticket to a user waiting for cancellation that has been received in advance.

When the ticket to be canceled is sold to a new user (step 174), the server 10 rearranges the registration of the ticket (step 176). Specifically, first, the ID of the person who wishes to cancel the ticket registered in the ticket is cancelled. As a result, the ticket to be canceled can be registered with another ID. The server 10 then registers the ticket with the ID of the new prospective purchaser. Finally, the server 10 transmits a message of successful cancellation to the terminal 14 .

If the ticket sale is not completed within the ticket sale period (step 174), the server 10 sends a message indicating that cancellation is not possible to the terminal 14 (step 178).

When the terminal 14 receives the transmission from the server 10 (step 180), it determines whether or not the cancellation has been established based on the received result (step 182). As a result, if the cancellation is not established, the result of cancellation NG is displayed on the display (32) (step 184).

On the other hand, if the cancellation is successful, the process to be executed at the terminal 14 is performed to invalidate the ticket (step 186). For example, as in Embodiment 1, when both registered face information and ticket information are stored in the storage (26) of the terminal 14, at least one of them is invalidated, or Information is disassociated. As a result, the terminal 14 cannot display the ticket information on the display (32).

As described above, according to the system display device of this embodiment, a user who cannot participate in an event for some reason can apply to cancel the purchased ticket. Then, if there is another person who wishes to purchase a ticket, the cancellation can be established and the ticket can be sold to the person who wishes to purchase the ticket.

As for illegal resale of tickets using cancellation, it is conceivable that the ticket owner has a meeting with the prospective purchaser in advance, and on the premise of receiving a reward, cancels the ticket at the timing when the purchaser can purchase it. . According to the system of this embodiment, it is not possible to know when and to whom the cancellation ticket will be sold, so it is possible to prevent such fraud. Then, such a chance can be appropriately given to the user who wants to cancel the ticket and the user who wants to purchase the ticket.

By the way, in Embodiment 3 described above, the condition for canceling a ticket is that the ticket can be sold to another person who wishes to purchase the ticket, but the condition is not limited to this. Ticket cancellation conditions can be appropriately set according to various requests.
