Electronic devices, operating methods and systems

[0001] The present disclosure relates to updating and registering a device identifier that identifies an electronic device when the device is factory reset.

[0002] Digital TV services utilizing wired or wireless networks are becoming more widespread. Digital TV services can offer a variety of services not available with existing analog broadcasting services.

[0003] For example, IPTV (Internet Protocol Television), a type of digital TV service, and smart TV services offer interactivity, allowing users to actively choose the type of program they want to watch and when. Building on this interactivity, IPTV and smart TV services can also offer a variety of additional services, such as internet search, home shopping, and online games.

[0004] Conventional TVs are registered and used on a space policy server that manages home appliances. For this purpose, a device identifier is required to identify the TV.

[0005] The device identifier can be a value hashed using the SHA (Secure Hash Algorithm)-512 function of the wired MAC (Media Access Control) address.

[0006] However, since the MAC address of a TV is a unique value, the same device identifier is always used even if the product's owner changes, such as when selling a used TV.

[0007] Accordingly, the previous owner of the TV may have the TV's device identifier on the space policy server, which may cause problems in using or controlling the TV's product information with the previous owner's account.

[0008] An object of the present disclosure may be to change the device identifier when the owner of an electronic device changes, thereby invalidating the device identifier of the previous owner.

[0009] The purpose of the present disclosure may be to prevent the previous owner from using or controlling information about the current owner's electronic device by changing the device identifier registered in the space policy server when the owner of the electronic device changes.

[0010] An electronic device according to an embodiment of the present disclosure may include a communication circuit that performs communication with an external device or server, and a processor that, when paired with the external device, receives a MAC (Media Access Control) address and product initialization information of the external device from the external device, generates a device identifier using the MAC address and the product initialization information, and transmits the generated device identifier to the server through the communication circuit.

[0011] An operating method of a system according to an embodiment of the present disclosure may include: a step in which a first electronic device receives, when paired with an external device, a MAC (Media Access Control) address and first product initialization information of the external device from the external device; a step in which the first electronic device generates a first device identifier using the MAC address and the first product initialization information; a step in which the first electronic device transmits the generated first device identifier to a server; and a step in which the server registers the first device identifier as a device identifier of the external device.

[0012] In a system including an external device, first and second electronic devices, and a server according to an embodiment of the present disclosure, when pairing with the external device, the first electronic device receives a MAC (Media Access Control) address and first product initialization information of the external device from the external device, generates a first device identifier using the MAC address and the first product initialization information, transmits the generated first device identifier to a server, and the server can register the first device identifier as a device identifier of the external device.

[0013] According to an embodiment of the present disclosure, the device identifier of the display device (100) may change due to product initialization of the display device (100).

[0014] Accordingly, the problem of the existing owner of the display device (100) using the product information of the display device (100) or performing remote control of the display device (100) can be prevented.
