Abstract

Embodiments of the present invention relate to the embedding of signature or watermark identification into digitally encoded audio data. More specifically, the present invention relates to embedding a unique digital identifier into the sub or super-audio frequency of digital audio data. As such, the present invention allows for an inaudible watermark to be embedded into any digital audio data.

Claims

AMENDED CLAIMS[received by the International Bureau on 29 April 2002 (29.04.02); original claim 1 amended; new claims 6-9 added; remaining claims unchanged (2 pages)]
1. A method for providing digital infoπnation to an Internet device, the method comprising: providing an Internet device having a unique identifying signature so that said Internet device is individually identifiable; and providing digital information from the Internet to the Internet device, wherein the Internet device incorporates its unique identifying signature into the provided digital information so that any digital reproduction of the provided digital information may be readily identified and attributed to the uniquely identified Internet device.
2. The method of Claim 1 wherein the Internet device is a PC.
3. The method of Claim 1 wherein the Internet device is a MP3 type player.
4. The method of Claim 1 wherein the identifying signature of the Internet device is incorporated with the digital information by mixing an inaudible, data-modulated analog signal onto an existing audio signal of the digital information.
5. The method of Claim 4 wherein the data-modulated analog signal comprises a tone burst modulation waveform.
7
6. The method of Claim 2, further comprising the PC copying said provided digital information, into which has been incoφorated the unique identifying signature, on a compact disc, so that said unique identifying signature is also copied onto the compact disc, and wherein a listener does not hear said unique identifying signature when playing the copied digital information.
7. The method of Claim 6, wherein said provided digital information is music.
8. The method of Claim 3 further comprising the MP3 type player making a digital copy of said provided digital information, into which has been incorporated the unique identifying signature, so that said unique identifying signature is also copied, wherein a listener does not hear said unique identifying signature when playing the copied digital information.
9. The method of Claim 8, wherein said provided digital information is music.
