Secure element authentication using over the air optical communication

Abstract

A system for facilitating secure communications accesses a secure element in response to determining that an authorized user operates the system. The system causes a light emitter to emit an output light signal for detection by a second system. The output light signal is emitted according to a predefined field of view, which operates as a constraint to prevent devices outside of the field of view from detecting the output light signal. The system also configures the light detector to detect a second output light signal emitted by a second light emitter of the second system. In response to (i) detection of the output light signal by a second light detector of the second system and (ii) detection of the second output light signal by the light detector, the system enables secure communication between the system and the second system.
