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.

Claims

1. A method for near field authentication of a source the source using an audio transceiver computing device 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.

2. The method of claim 1 further comprising

displaying a user interface on the audio transceiver computing device requesting the biometric data from a user;

and

responsive to receiving the biometric data, generating the periodic enclosed content message, wherein the content in each period of the periodic enclosed content message includes the biometric data.

3. The method of claim 1 or 2, wherein the transmitting step further comprises transmitting the modulated carrier wave for a predetermined number of periods, or a predetermined period of time.

4. The method of claim 1 or 2, wherein the transmitting step further comprises transmitting the modulated carrier wave until a stop indication is received from a user.

5. The method of claims 1 to 4 wherein the modulated carrier wave comprises a sound wave.
