FIG. 9 is a flowchart showing a process flow of the control unit 310 of the server apparatus 300. First, mutual authentication by TLS is performed in response to a connection request from the terminal device 200 (S300a). If there is no problem as a result of the authentication, an advertisement data transmission request for the display device ID from the terminal device 200 is accepted, and it is checked whether the advertisement for the display device ID has been updated (S300b). The check compares the current date and time with the value of the field “next update date and time” of the display device management information record corresponding to the display device ID. When it has been updated (NO), warning information is transmitted to the terminal device 200 (S300m). If not updated (YES), the advertisement data corresponding to the display device ID, the update date / time, and the verification information are acquired through the database control unit 320 (S300c), and the acquired update date / time is also converted into text. After superimposing the information (S300d), it is transmitted to the terminal device (S300e).

Fig. 10 shows an example of advertisement data with the update date converted to text. As illustrated in FIG. 10, by superimposing the update date and time on the displayed advertisement, it is possible to prevent the user from attempting to update the updated display device 100.

Next, it waits for a transmission completion notification from the terminal device, and if there is no notification within a predetermined time (NO in S300g), it is determined that there is a possibility that the display device has failed, and the server administrator is notified through the display unit 390 ( S300n). If there is a notification (YES in S300g), the terminal device 200 verifies whether fraud has been performed based on the information received by the transmission completion notification (S300h). This process will be described later. When it is determined that fraud has not been performed (YES in S300i), the terminal management information (S300j) and the display device management information (S300k) are updated through the database control unit 320. This update will also be described later.

If it is determined that fraud has been performed (NO in S300i), the server administrator is notified through the display unit 390 (S300p), and warning information is also transmitted to the terminal device 200 (S300q).

<Received information verification process>
With reference to FIG. 11, a processing flow of the control unit 310 when the server apparatus 300 verifies the transmission completion notification transmitted from the terminal apparatus 200 will be described.

FIG. 11 is a flowchart showing a process flow of the control unit 310 of the server apparatus 300. First, the installation location and reference verification information corresponding to the display device ID are acquired through the database control unit 320 using the display device ID as a search key (S310a). The acquired installation location and the received position information are compared (S310b). If they do not match (NO in S310c), it is determined that the notification is invalid. This process assumes an act of detecting an act of moving the display device 100 from the original setting location, moving to the home, for example, and accumulating points illegally. In this case, the fact that the received location information and the installation location do not match is utilized.

If they match (YES in S310c), the reference verification information is compared with the received verification information (S310d). Specifically, the received verification information is compared with reference verification information corresponding to the display device ID. If they match in comparison (YES in S310e), it is determined as a valid notification, and if not (NO in S310e), it is determined as an unauthorized notification. With this process, it is possible to detect an illegal act such as sending a transmission completion notification without rewriting the advertisement data. This is because valid verification information can be acquired only by transmitting appropriate data to the display device 100. Further, even if the verification information of the other display device 100 and the past verification information are stored and reused, the verification information includes the hash value of the advertising data displayed on the display device 100 immediately before and the advertising device. Since the ID and the next update date / time are concatenated, such information does not match the reference verification information. Furthermore, since the verification information is encrypted only with a secret key that is managed only by the server device 300 and is associated with the advertising device ID associated with the advertising device ID, it is difficult to create the information illegally.

<Terminal (status) information update processing>
12, when the server apparatus 300 determines that the transmission completion notification transmitted from the terminal apparatus 200 is valid, the server apparatus 300 updates the record corresponding to the terminal ID in the terminal management information storage unit 370. A processing flow of the control unit 310 will be described.

FIG. 12 is a flowchart showing a process flow of the control unit 310 of the server apparatus 300. First, the number of points corresponding to the display device ID received from the terminal device 200 is searched through the database control unit 320 (S320a). Next, the accumulated point number corresponding to the terminal device ID of the terminal device 200 is searched (S320b), the point number of S320a is added to the accumulated point number (S320e), and the terminal management information is obtained through the database control unit 320. The point-added accumulated points are written back to the record corresponding to the terminal device ID in the storage unit 370.

<Display device management information update processing>
After the server device 300 determines that the transmission completion notification transmitted from the terminal device 200 is valid, the server device 300 updates the record corresponding to the display device ID in the display device management information storage unit 350 with reference to FIG. A flow of processing of the control unit 310 will be described.

FIG. 13 is a flowchart showing a process flow of the control unit 310 of the server apparatus 300. First, the value stored in the field “next advertisement ID” from the record corresponding to the display device ID (corresponding to the advertisement ID of the advertisement already displayed on the display device 100) is stored in the field “next update date”. Get the value and the value stored in the field "Location". Next, the value stored in the field “display period” is acquired from the record of the advertisement management information storage unit 350 corresponding to the acquired advertisement ID (S330a), and added to the acquired next update date and time (S330b). With this processing, even if the actual update is delayed from the next update date and time, the next update date and time is shifted accordingly, so that the actual display period is not shortened.

Next, an advertisement to be displayed on the advertisement display device 100 next time is determined (S330c). As a specific determination method, for example, from all records in the advertisement management information storage unit 350, the value of the field “display period” is consistent with the next update date and time after the addition, and the value of the field “display location” It shall correspond with the said installation place, and the advertisement ID of the record is specified as the next advertisement ID.

Next, reference verification information is generated (S330d). Specifically, the hash value of the update date and time superimposed advertisement data generated in step S300d is calculated, and the concatenation of the advertisement display device ID and the next update date and time is stored in the field “display device ID”. Encrypt with Next, the next advertisement ID is stored in the field “next advertisement ID”, the next update date / time is stored in the field “next update date / time”, and the reference verification information is stored in the field “reference verification information”. The record of the device management information storage unit 350 is updated (S330e).

With the above configuration, it is possible to add points to the terminal device 200 in which the display device 100 is rewritten to an appropriate advertisement while preventing fraud, and the advertising agency can reduce the installation cost and ecology without incurring human costs. From the viewpoint, it is possible to realize rewriting of advertisements using electronic paper, which is desirable.

<Update omission check process>
With reference to FIG. 14, a processing flow of the control unit 310 when detecting an update update of an advertisement on each display device 100 in the server device 300 will be described. This process is executed at predetermined time intervals (eg, 1 hour).

FIG. 14 is a flowchart showing a process flow of the control unit 310 of the server apparatus 300. First, as an initialization process, the index i is initialized to 0, and the list for managing the update omission display device is emptied (S340a). Next, while incrementing the index, it is checked whether or not all the display devices are not updated, and for those that are not updated, the display device ID is added to the list (S340b to S40h).

More specifically, a display device management information record related to the i-th display device is acquired (S340c), the current date and time are acquired (S340d), and the difference between the current date and the next update date and time is a predetermined positive number (example) : 1 hour) is checked (S340e), and if it is larger (YES), it is determined that update is missed, and a predetermined positive number is added to the value of the field "point number" of the acquired display device management information record (S340f), the display device ID corresponding to the i-th display device is registered in the list (S340g). This process is continued (S340g). If S340e is smaller (NO), the process proceeds directly to S340h.

When the update omission check for all the display devices is completed (NO in S340b) and the display device ID is registered in the list (S340i), the server administrator is notified through the display unit 390 that the update omission has occurred (S340i). S340j). As a result, it is possible to specify a display device that is not updated, and it is possible for an advertising agency to manually handle only the display device that is not updated.

Further, the installation location corresponding to the display device ID of update update is notified to the terminal having the terminal ID included in the field “region” that there is an update update display device (S340k). Specifically, the display device identification information and the installation location are acquired from the record corresponding to the display device ID, and if the advertisement is rewritten now, a message that points are added more than usual is added and transmitted. In this way, it is possible to prompt the user to respond to the update failure by notifying the user of the display device of update failure, and to accelerate the response by adding points.
