Abstract
Device, system and method of securely transmitting information from a mobile device or application or a user device to a mobile phone or other acoustic aware devices using audio frequency encoded data and security token transmission.
Claims20
A transmitter for securely transmitting data, comprising:
- an actuator configured to generate electrical impulses, the electrical impulses including user credentials comprising an electronic token;
- an encoder configured to serialize and encode the user credentials including the electronic token;
- and
- a transducer configured to sonically transmit the electrical impulses including the user credentials and electronic token in response to actuation of the actuator,
- wherein the electrical impulses comprises modulated audio frequency carrier signals,
- wherein the audio frequency carrier signals are transmitted using modulation schemes involving multi-frequency FSK (frequency shift keying) and multiple transmissions,
- wherein multiple FSK frequency pairs are used in a sequence of transmissions,
- wherein data in the sequence is transmitted at different data rates, and
- wherein, in the sequence, two frequencies are transmitted alternatingly at a rate of a bit rate.

- a transducer configured to sonically transmit the electrical impulses as sound signals;
- and
- a user device configured to securely receive the sound signals, the user device comprising a data processing module,
- wherein the electrical impulses comprises modulated audio frequency carrier signals,
- wherein the audio frequency carrier signals are transmitted using modulation schemes involving multi-frequency FSK (frequency shift keying) and multiple transmissions,
- wherein multiple FSK frequency pairs are used in a sequence of transmissions,
- wherein data in the sequence is transmitted at different data rates, and
- wherein, in the sequence, two frequencies are transmitted alternatingly at a rate of a bit rate.

- and
- decoding the sound signals representing the user credentials and sending decoded credentials, including the electronic token, to a processing network,
- wherein the electrical impulses comprises modulated audio frequency carrier signals,
- wherein the audio frequency carrier signals are transmitted using modulation schemes involving multi-frequency FSK (frequency shift keying) and multiple transmissions,
- wherein multiple FSK frequency pairs are used in a sequence of transmissions,
- wherein data in the sequence is transmitted at different data rates, and
- wherein, in the sequence, two frequencies are transmitted alternatingly at a rate of a bit rate.
