Abstract
A method and system for synthesizing electronic watermarks is disclosed. The method includes generating electronic watermark sounds for music data by converting harmonic overtones that match the music data into signals. The generated electronic watermark sounds are then synthesized into the music data. The synthesized electronic watermark sounds and the music data are then output via various ways. In one embodiment, an encoded music file is generated, which can be sent to a recipient via a network or recorded on any of various recording media for distribution.
Claims24
A method of electronically watermarking audio data, the method comprising:
- (a) selecting at least two different orders of harmonic overtones for original music data;
- (b) generating a digital signal for a sound of the original music data, the digital signal comprising harmonic overtones of the selected orders for the sound, the harmonic overtones being of a different frequency than the sound and within the humanly audible frequency range;
- and
- (c) synthesizing the digital signal into the original music data.
A system for electronically watermarking audio data, the system comprising:
- means for generating electronic watermark sounds for original music data, the electronic watermark sounds comprising harmonic overtones of the original music data, the harmonic overtones being of a different frequency than the original music data and within the humanly audible frequency range;
- means for synthesizing the generated electronic watermark sounds into the original music data;
- and
- means for outputting watermarked music data comprising the synthesized electronic watermark sounds and the original music data.
A computer usable medium having computer readable program code embodied therein for synthesizing electronic watermarks, the computer readable code comprising instructions for:
- generating digital signals for music data, the digital signals comprising harmonic overtones of at least two preselected orders for the music data, the harmonic overtones being of different frequencies than the music data and within the humanly audible frequency range, the harmonic overtones changing tone as the original music data changes;
- synthesizing the digital signals into the music data;
- and
- outputting the synthesized digital signals and the music data.
A method of watermarking audio data, the method comprising:
- generating digital signals for music data, the digital signals comprising harmonic overtones of at least two preselected orders for the music data, the harmonic overtones being of different frequencies than the music data and within the humanly audible frequency range, the harmonic overtones changing tone as the original music data changes;
- synthesizing the digital signals into the music data;
- and
- outputting the synthesized digital signals and the music data.
An audio watermarking system comprising:
- a processor receiving original music data;
- a computer program operating on the processor, the program being configured to:
- generate digital signals for the original music data, the digital signals comprising harmonic overtones of at least two preselected orders for the original music data, the harmonic overtones being of different frequencies than the original music data and within the humanly audible frequency range, the harmonic overtones changing tone as the original music data changes;
- synthesize the digital signals into the original music data;
- and
- output watermarked music data comprising the synthesized digital signals and the original music data;
- and
- an output module configured to provide the watermarked music data.
