Abstract

Techniques described herein are directed toward enabling a transfer of access rights for an electronic device between users. In embodiments a transferee device may receive a first request to obtain access rights for an electronic device associated with a transferor device. The transferor device may receive a second request to grant access rights for the electronic device. Embodiments may include receiving, at the transferee device, a device key associated with the electronic device and storing the device key in association with the electronic device. Embodiments may further include issuing a command from at least one of the transferee or transferor devices to unlock the electronic device, and causing the electronic device to comply with the command to unlock if the at least one of the transferee or transferor devices that issues the command has access to the device key when the command is issued.

First claim

What is claimed is:

1. A method comprising:
receiving, at a transferee user device, a first request to obtain access rights for an electronic device associated with a transferor user device;
providing, to the transferor user device, a second request to grant access rights for the electronic device associated with the transferor user device;
receiving, at the transferee user device, a device key associated with the electronic device;
storing the device key in association with the electronic device in memory of the transferee user device;
issuing a command from at least one of the transferee user device or the transferor user device to unlock the electronic device; and
causing the electronic device to comply with the command to unlock if the at least one of the transferee user device or the transferor user device that issues the command has access to the device key when the command is issued.

2. The method of claim 1 , wherein the device key is included within an encrypted packet of data, the encrypted packet of data being accessible by the electronic device.

3. The method of claim 2 , wherein the encrypted packet of data includes at least one dynamic data element.

4. The method of claim 3 , wherein the at least one dynamic data element comprises a counter value.

5. The method of claim 3 , wherein the at least one dynamic data element comprises a device identifier for the transferee user device.

6. The method of claim 1 , wherein the method further comprises:
providing, to the transferor user device, an identifier of an account associated with a user of the transferee user device.

7. The method of claim 1 , wherein the method further comprises:
using an optical code reader communicatively coupled with the transferee user device to read a machine-readable code generated by the transferor user device.

8. A user device associated with a user comprising:
a processor; and
a memory including instructions that, when executed with the processor, cause the user device to, at least:
receive a first request to obtain access rights for an electronic device associated with a transferor user device;
provide, to the transferor user device, a second request to grant access rights for the electronic device associated with the transferor user device;
receive a device key associated with the electronic device;
store the device key in association with the electronic device in memory of the user device;
issue a command from at least one of the user device or the transferor user device to unlock the electronic device; and
cause the electronic device to comply with the command to unlock if the at least one of the user device or the transferor user device that issues the command has access to the device key when the command is issued.

9. The user device of claim 8 , wherein the device key is included within an encrypted packet of data, the encrypted packet of data being accessible by the electronic device.

10. The user device of claim 9 , wherein the encrypted packet of data includes at least one dynamic data element.

11. The user device of claim 10 , wherein the at least one dynamic data element comprises a counter value.

12. The user device of claim 10 , wherein the at least one dynamic data element comprises a device identifier for the user device.

13. The user device of claim 10 , wherein the instructions further cause the user device to:
provide, to the transferor user device, an identifier of an account associated with the user of the user device.

14. The user device of claim 10 , wherein the instructions further cause the user device to:
use an optical code reader communicatively coupled with the user device to read a machine-readable code generated by the transferor user device.

15. A non-transitory computer-readable medium storing specific computer-executable instructions that, when executed by a processor, cause a user device operated by a first user to at least:
receive a first request to obtain access rights for an electronic device associated with a transferor user device;
provide, to the transferor user device, a second request to grant access rights for the electronic device associated with the transferor user device;
receive a device key associated with the electronic device;
store the device key in association with the electronic device in memory of the user device;
issue a command from at least one of the user device or the transferor user device to unlock the electronic device; and
cause the electronic device to comply with the command to unlock if the at least one of the user device or the transferor user device that issues the command has access to the device key when the command is issued.

16. The computer-readable medium of claim 15 , wherein the device key is included within an encrypted packet of data, the encrypted packet of data being accessible by the electronic device.

17. The computer-readable medium of claim 16 , wherein the encrypted packet of data includes at least one dynamic data element.

18. The computer-readable medium of claim 17 , wherein the at least one dynamic data element comprises a counter value.

19. The computer-readable medium of claim 17 , wherein the at least one dynamic data element comprises a device identifier for the user device.

20. The computer-readable medium of claim 15 , wherein the instructions further cause the user device to:
use an optical code reader communicatively coupled with the user device to read a machine-readable code generated by the transferor user device.
