Abstract
A method and apparatus for monitoring a localized region of a touch screen for a plurality of sensor inputs to identify a camera profile of at least one user equipment. In response to identifying the camera profile initiating a localized visual data exchange by displaying data within a region defined by the camera profile. Data communication is initiated with the user equipment over the alternative communication. In order to maintain a secure communication the invention periodically monitors the localized region of the touch screen for the plurality of sensor inputs identified as the camera profile during the localized visual data exchange while communicating over the alternative communication network.
