Abstract

Embodiments related to the establishment of a relationship between wireless devices are disclosed. In one disclosed embodiment, a wireless device includes an image capture device, a wireless transmitter and receiver, a logic subsystem, and memory comprising instructions executable by the logic subsystem to capture a first image via the image capture device, identify authentication features of the first image, and receive authentication data from a remote media device via the wireless receiver that comprises authentication features of a second image. The instruction further cause the logic subsystem to compare the authentication features of the second image to the authentication features of the first image to establish a trusted relationship with the remote media device if the authentication features of the second image exhibit a pre-determined relationship to the authentication features of the first image.

capturing one or more images at a first media device via an image capture device;

identifying one or more authentication features of the one or more images captured at the first media device;

receiving authentication data from a second media device at the first media device via wireless communication, the authentication data comprising one or more authentication features of one or more images captured at the second media device; and

establishing a trusted relationship at the first media device with the second media device if the one or more authentication features of the one or more images captured at the second media device exhibit a pre-determined relationship to the one or more authentication features of the one or more images captured at the first media device.

2. The method of claim 1, further comprising, transmitting authentication data from the first media device to the second media device via wireless communication, the authentication data transmitted to the second media device indicating the one or more authentication features of the one or more images captured at the first media device, where the authentication data transmitted to the second media device causes the second media device to:

establish a trusted relationship with the first media device if the one or more authentication features transmitted to the second media device exhibit a pre-determined relationship to the one or more authentication features of the one or more images captured at the second media device; and

decline the trusted relationship with the first media device if the one or more authentication features transmitted to the second media device do not exhibit the pre-determined relationship to the one or more authentication features of the one or more images captured at the second media device.

3. The method of claim 1, further comprising, establishing a personal area network between the first media device and the second media device only if the trusted relationship has been established at the first media device with the second media device.

4. The method of claim 3, further comprising, transmitting protected data from the first media device to the second media device through the personal area network via wireless communication only if the trusted relationship has been established at the first media device with the second media device.

5. The method of claim 1, further comprising, receiving provisional data from the second media device at the first media device via wireless communication;

and quarantining the provisional data at the first media device if the trusted relationship has been declined at the first media device with the second media device.

6. The method of claim 1, where identifying the one or more authentication features of the one or more images captured at the first media device includes identifying a blur kernel from the one or more images captured at the first media device;

and

where the one or more authentication features of the one or more images captured at the first media device comprise the blur kernel.

7. The method of claim 1, where identifying the one or more authentication features of the one or more images captured at the first media device includes identifying a motion path of the first media device;

and where the one or more authentication features of the one or more images captured at the first media device indicates the motion path of the first media device.

8. The method of claim 7, where the one or more authentication features received from the second media device indicates a motion path of the second media device;

and

where comparing the one or more authentication features received from the second media device to the one or more authentication features of the one or more images captured at the first media device includes identifying a deviation of the motion path of the second media device from the motion path of the first media device.

9. A media device, comprising:

an image capture device;

a wireless receiver configured to receive data broadcast by remote media devices;

a logic subsystem; and

memory comprising instructions that are executable by the logic subsystem to;

capture a first image via the image capture device;

identify one or more authentication features of the first image;

receive authentication data from a remote media device via the wireless receiver, the authentication data comprising one or more authentication features of a second image;

compare the one or more authentication features of the second image to the one or more authentication features of the first image;

establish a trusted relationship with the remote media device if the one or more authentication features of the second image exhibit a pre-determined relationship to the one or more authentication features of the first image; and

decline the trusted relationship with the remote media device if the one or more authentication features of the second image do not exhibit the pre-determined relationship to the one or more authentication features of the first image.

10. The media device of claim 9, further comprising, a wireless transmitter configured to transmit data to remote media devices;

and

where the memory further comprises instructions that are executable by the logic subsystem to cause the logic subsystem to;

transmit authentication data to the remote media device via the wireless transmitter, the authentication data transmitted to the remote media device indicating the authentication features of the first image.

11. The media device of claim 10, where the pre-determined relationship is a first pre-determined relationship, and where the authentication data transmitted to the remote media device causes the remote media device to:

establish a trusted relationship with the media device if the authentication features of the first image exhibits a second pre-determined relationship to the authentication features of the second image; and

decline the trusted relationship with the media device if the authentication features of the first image do not exhibit the second pre-determined relationship to the authentication features of the second image.

12. The media device of claim 9, where the first image is one of a plurality of images captured via the image capture device of the media device;

and

where the authentication data received from the remote media device further indicates one or more authentication features of a plurality of images including the second image captured at the remote media device.

13. The media device of claim 9, further comprising, a wireless transmitter configured to transmit data to remote media devices;

and

where the memory further comprises instructions that are executable by the logic subsystem to cause the logic subsystem to transmit protected data to the remote media device via the wireless transmitter only if the trusted relationship has been established with the remote media device.

14. The media device of claim 9, where the memory further comprises instructions that are executable by the logic subsystem to cause the logic subsystem to quarantine provisional information received from the second media device via the wireless receiver until the trusted relationship has been established at the first media device with second media device.

15. The media device of claim 9, further comprising a graphical display, and where the memory further comprises instructions that are executable by the logic subsystem to cause the logic subsystem to:

receive a device pairing request from the remote media device via the wireless receiver; and
