Abstract
A system and method are disclosed for use of a passive sensor within a mobile device as a separate authentication mechanism to exchange a secure key with a desired network. A network access point presents an encoded bit stream via an audio signal over an audio channel or a video signal within a video presentation. Each signal type is configured for reception by a passive sensor on the mobile device. This received information would be used to generate the private key within the mobile device for encrypting the wireless communication channel. Only mobile devices within audio or visual range of the presentation may be authenticated and thus securely connected to the network.
