For example, the communication terminal 300 receives user information corresponding to the user ID from the cloud server 40 and determines whether or not the user ID includes the terminal ID. If it is determined that it has been registered, the process proceeds to S810. If it is determined that it has not been registered, the process proceeds to S812.

In S810, it is determined whether or not the registered terminal ID matches the terminal ID of the communication terminal 300. If it is determined that they match, the process proceeds to S814. If it is determined that they do not match, the process proceeds to S812.

In S812, the network communication unit 310 transmits the terminal ID stored in the terminal identification information storage unit 314 to the cloud server 40. The cloud server 40 may store the received terminal ID in association with the user ID of the user 80 instead of the registered terminal ID. If the communication terminal 300 determines that the terminal IDs do not match in step S810, the communication terminal 300 inquires of the user 80 whether or not to re-register the terminal ID, and receives the instruction to re-register. Instead of the ID, the received terminal ID may be stored in association with the user ID of the user 80.

The content received by the network communication unit 310 is stored by the icon storage unit 340. In S828, the BLE communication unit 320 transmits the association information generated by the association information generation unit 334 to the display device 100.

In S830, the write mode request transmission unit 338 transmits the write mode request to the display device 100 via the BLE communication unit 320. In S832, the BLE communication unit 320 transmits the content received from the cloud server 40 in S826 to the display device 100. Then, the process ends.

FIG. 9 schematically shows an example of the processing flow by the cloud server 40. Here, an example of the flow of processing in which the communication terminal 300 logs in to the cloud server 40 and registers or re-registers the terminal ID is shown. Each process illustrated in FIG. 9 is executed mainly by a control unit included in the cloud server 40.

In S902, the user ID and password are received from the communication terminal 300. In S904, it is determined whether or not the user ID received in S902 matches the registered user ID, and the password received in S902 matches the password stored in association with the user ID. If it is determined that they match, the process proceeds to S904, and if it is determined that they do not match, the process returns to S902.

In S906, login is permitted. In S908, the user information stored in association with the user ID received in S902 is transmitted to the communication terminal 300. In step S910, it is determined whether a terminal ID is received from the communication terminal 300. If it is determined that it has been received, the process proceeds to S912. If it is determined that it has not been received, the process ends.

In S912, it is determined whether or not the terminal ID has been registered for the user ID received in S902. If it is determined that it has not been registered, the process proceeds to S914. If it is determined that it has been registered, the process proceeds to S916. In S914, the terminal ID received in S910 is registered in association with the user ID received in S902.

In S916, it is determined whether or not the terminal ID received in S910 matches the terminal ID registered for the user ID received in S902. If it is determined that they do not match, the process proceeds to S918. If it is determined that they match, the process ends.

In S918, it is determined whether or not a predetermined period has elapsed since the last re-registration of the terminal ID. The predetermined period may be arbitrarily set, for example, 30 days. If it is determined in S918 that the time has elapsed, the process proceeds to S920, and if it is determined that the time has not elapsed, the process proceeds to S922.

In S920, the terminal ID received in S910 is re-registered. That is, instead of the registered terminal ID, the terminal ID received in S910 is registered. In S922, re-registration is rejected. The cloud server 40 notifies the communication terminal 300 that the re-registration is rejected. Then, the process ends. In this way, by prohibiting re-registration until a predetermined period elapses, it is possible to suppress the reuse of the account due to frequent re-registration of the terminal ID.
