Abstract
In a computing device, both an address of a first device and a secret are graphically encoded to generate one or more images that can be captured by a second device. The second device captures and decodes the one or more images, and sends a communication initiation request to the address of the first device. The communication initiation request includes the address of the second device and identifies the secret. Communication between the first and second device continues only if the first device verifies, based on the communication initiation request, that the second device knows the secret.
