Near field authentication through communication of enclosed content sound waves
First Claim
1. A system for near field authentication of a source comprising:
- an audio receiving computing device having an audio input configured to receive a near field authentication request from a mobile computing device by;
scanning a plurality of predetermined frequencies to detect a signal using the audio input;
verifying, responsive to detecting the signal, that the signal includes at least one enclosed content message; and
extracting content from the enclosed content message, wherein the content includes device identification data including a bit array derived from user-configurable and non-user-configurable data specific to the mobile computing device and wherein the signal is a modulated carrier wave comprising a sound wave.

Abstract
A method for near field authentication of sources using an audio transceiver computing device includes scanning a plurality of predetermined frequencies for a free frequency, selecting the free frequency from the plurality of predetermined frequencies, generating a periodic enclosed content message, generating a modulated carrier wave representing the periodic enclosed content message, and transmitting the modulated carrier wave at the free frequency. A method for near field authentication of sources using a microphone input of a receiving computing device includes scanning a plurality of predetermined frequencies to detect a signal using the microphone input, verifying, responsive to detecting the signal, that the signal includes at least one enclosed content message, and extracting a content from the enclosed content message.

8. A non-transitory computer readable medium useful in association with an audio transceiving computing device which includes one or more processors, a receiver, logic that executes in the one or more processors, an audio input, and a memory, the computer readable medium including instructions configured to cause the audio transceiving computing device, by execution of the instructions in the one or more processors, to receive a near field authentication request of a source by:
-
scanning a plurality of predetermined frequencies to detect a signal using the audio input; verifying, responsive to detecting the signal, that the signal includes at least one enclosed content message; and extracting content from the enclosed content message, wherein the content includes device identification data including a bit array derived from user-configurable and non-user-configurable data received from the source and wherein the signal is a modulated carrier wave comprising a sound wave. - View Dependent Claims (9, 10, 11, 12, 13)
