ABSTRACT:
A theft protection method and promotion system for audio media for providing a secure and irreversible way to protect audio containing media content, while supplying an enhanced promotional potential. The inventive device includes a proposed process for the preparation and digital conversion of initial unprotected audio media, a method for producing an irreversibly encrypting waveform to be embedded into audio media, a method for producing a waveform that audibly nullifies the encrypting waveform, a process for the down-sampling and encoding of protected material, and a distribution and promotion system that provides a means by which an end user can access and interact with the protected material.
