Abstract

A server in a communications network establishes a communication channel between a user's device and another device having a display. Particularly, the server generates a Quick Response (QR) code utilizing one or more parameters, and sends it to a device for display to a user. Using his or her device, the user captures an image of the displayed QR code and extracts the parameters using an image analysis technique. The device then sends the extracted parameters back to the server, which then utilizes them to authenticate the user and establish the communications session.
