Abstract

A method of wireless charging authentication for a wireless charging device includes receiving an authentication information from an electronic device for authentication of charging; determining whether the authentication succeeds or not according to the authentication information; and supplying wireless power to the electronic device for charging if the authentication succeeds or stopping to supply wireless power to the electronic device if the authentication fails.

Claims

1. A method of wireless charging authentication for a wireless charging device, comprising:

receiving an authentication information from an electronic device for authentication of charging;

determining whether the authentication succeeds or not according to the authentication information; and

supplying wireless power to the electronic device for charging if the authentication succeeds or stopping to supply wireless power to the electronic device if the authentication fails.

2. The method of claim 1, further comprising:

sending a first response to the electronic device to indicate whether the authentication is needed in response to a query received from the electronic device.

3. The method of claim 1, wherein the step of determining whether the authentication succeeds or not according to the authentication information comprises:

determining that the authentication fails if the wireless charging device does not receive the authentication information for a predefined duration.

4. The method of claim 1, further comprising:

sending a second response to the electronic device to indicate whether the authentication succeeds or fails.

5. The method of claim 1, wherein the wireless charging device starts supplying wireless power or keeps on supplying wireless power if the authentication succeeds.

6. The method of claim 1, wherein the wireless charging device stops supplying wireless power or releases a warning signal if the authentication fails.

7. The method of claim 1, wherein the wireless charging device receives the authentication information from the electronic device periodically.

8. The method of claim 1, wherein the authentication information comprises at least one of a security code, a password, full or partial of an identity of the electronic device, an input to the electronic device, and information indicating that a user of the electronic device has completed a certain operation on the electronic device.

9. The method of claim 1, wherein the wireless charging device determines whether the authentication succeeds or not by comparing the received authentication information with data stored in a memory of the wireless charging device.

10. The method of claim 1, wherein the wireless charging device determines whether the authentication succeeds or not by manipulating the received authentication information and checking if a value derived from manipulation of the received authentication information equals a predefined value.

11. The method of claim 1, wherein the step of determining whether the authentication succeeds or not according to the authentication information comprises:

sending the received authentication information to a controller for determining the authentication succeeds or not by the controller.

12. The method of claim 1, further comprising:

sending an authentication success message to a controller to inform that the authentication for the electronic device succeeds;

wherein the authentication success message comprises at least one of an identity of the electronic device, an identity of the wireless charging device, and a location of the wireless charging device or the electronic device.

13. The method of claim 1, further comprising:

sending an authentication failure message to a controller to inform that the authentication for the electronic device fails;

wherein the authentication failure message comprises at least one of an identity of the electronic device, an identity of the wireless charging device, a location of the wireless charging device or the electronic device, and the reason of authentication failure.

14. The method of claim 1, further comprising:

sending a request to the electronic device for receiving the authentication information from the electronic device.

15. A wireless charging system, comprising:

an electronic device; and

a wireless charging device, for providing wireless power to charge at least one electronic device comprising the electronic device;

wherein the wireless charging device is configured to receive an authentication information from the electronic device for authentication of charging, determine whether the authentication succeeds or not according to the authentication information, and supply wireless power to the electronic device for charging if the authentication succeeds or stop supplying wireless power to the electronic device if the authentication fails.

16. The wireless charging system of claim 15, wherein the wireless charging device is further configured to send a first response to the electronic device to indicate whether the authentication is needed in response to a query received from the electronic device.

17. The wireless charging system of claim 15, wherein the wireless charging device determines that the authentication fails if the wireless charging device does not receive the authentication information for a predefined duration.

18. The wireless charging system of claim 15, wherein the wireless charging device is further configured to send a second response to the electronic device to indicate whether the authentication succeeds or fails.

19. The wireless charging system of claim 15, wherein the wireless charging device starts supplying wireless power or keeps on supplying wireless power if the authentication succeeds.

20. The wireless charging system of claim 15, wherein the wireless charging device stops supplying wireless power or releases a warning signal if the authentication fails.

21. The wireless charging system of claim 15, wherein the wireless charging device receives the authentication information from the electronic device periodically.

22. The wireless charging system of claim 15, wherein the authentication information comprises at least one of a security code, a password, an identity of the electronic device, an input to the electronic device, and information indicating that a user of the electronic device has completed a certain operation on the electronic device.

23. The wireless charging system of claim 15, wherein the wireless charging device determines whether the authentication succeeds or not by comparing the received authentication information with data stored in a memory of the wireless charging device.

24. The wireless charging system of claim 15, wherein the wireless charging device determines whether the authentication succeeds or not by manipulating the received authentication information and checking if a value derived from manipulation of the received authentication information equals a predefined value.

25. The wireless charging system of claim 15, wherein the wireless charging device sends the received authentication information to a controller of the wireless charging system for determining the authentication succeeds or not by the controller.

26. The wireless charging system of claim 15, wherein the wireless charging device is further configured to send an authentication success message to a controller of the wireless charging system to inform that the authentication for the electronic device succeeds, wherein the authentication success message comprises at least one of an identity of the electronic device, an identity of the wireless charging device, and a location of the wireless charging device or the electronic device.

27. The wireless charging system of claim 15, wherein the wireless charging device is further configured to send an authentication failure message to a controller of the wireless charging system to inform that the authentication for the electronic device fails, wherein the authentication failure message comprises at least one of an identity of the electronic device, an identity of the wireless charging device, a location of the wireless charging device or the electronic device, and the reason of authentication failure.

28. The wireless charging system of claim 15, wherein the wireless charging device is further configured to send a request to the electronic device for receiving the authentication information from the electronic device.

29.
