Digital handshake between devices

An electronic device for establishing a secure communications path with another device, comprising control circuitry, a camera, and a display, the control circuitry operative to:

• generate a first key;
• direct the display to display the first key;
• extract a second key from an image of the other device captured by the camera;
• select a process for generating a digital handshake key using both the first and second keys;
• and
• generate a digital handshake key using the selected process.

A method for selecting a device with which to establish a secure communications path, comprising:

• capturing an image using a first camera of a first electronic device;
• identifying at least second and third devices in the captured image;
• detecting a second camera of the second device and a third camera of the third device;
• determining whether the first device is in the field of view of the second camera or of the third camera;
• and
• in response to determining that the first device is in the field of view of the second camera, establishing a communications path with the second device.

Non-transitory computer readable media for establishing a communications path between a first device and a second device, comprising computer readable code recorded thereon for:

• capturing an image of the second device using the first device;
• extracting, from the image, a second key associated with the second device;
• selecting from a plurality of processes a process to be used for generating a digital handshake key;
• generating the digital handshake key using the selected process with the second key;
• and
• establishing a communications path with the second device using the digital handshake key.
