Abstract

A system and method for enabling a user to retrieve, decode, and utilize hidden data embedded in audio signals. An exemplary implementation includes a microphone structured to receive sound waves representative of an audio signal and hidden data embedded in the audio signal. The then microphone converts the received sound waves into an electrical output signal. The system also includes a processor electrically coupled to the microphone and configured to receive the electrical output signal in order to extract the hidden data and provide information represented by the hidden data as an output thereof. A user interface is also provided and is electrically coupled to the processor and configured to receive a first input from the user and activate the processor to selectively initiate extraction of the hidden data. The processor produces as an output the information represented by the hidden data. Finally, the system includes a user presentation mechanism configured to present the information to the user.
