Near field authentication through communication of enclosed content sound waves
DC CAFCFirst Claim
1. A method for near field authentication of a source, the source using an audio transceiver computing device, the method comprising:
- 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;
wherein each period of the periodic enclosed content message includes a begin indication, a content, and an end indication;
wherein the content includes biometric data and a bit array, the bit array being derived from user-configurable and non-user-configurable data specific to the audio transceiver computing device; and
wherein the modulated carrier wave comprises 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.
