Fingerprinting of Media Signals
First Claim
1. A method comprising:
- obtaining data representing a media signal;
searching the data for a digital watermark component;
obtaining information associated with the digital watermark component;
influencing a fingerprinting process according to the information associated with the digital watermark component; and
determining a fingerprint of the data representing the media signal utilizing the fingerprinting process influenced according to the information associated with the digital watermark component.

Abstract
The present invention relates generally to fingerprinting, e.g., a reduced-bit representation or other identifier of a media signal (e.g., audio, video or still images). One method recites: receiving a partial fingerprint of a media signal, wherein the partial fingerprint is derived from the media signal itself, the partial fingerprint being computed a first location; processing the partial fingerprint to obtain a more refined fingerprint, relative to the partial fingerprint, the act of processing occurring at a second location that is remote from the first location; and based at least in part of the refined fingerprint, identifying the media signal or information associated with the media signal. Another method recites: obtaining a fingerprint derived from a media signal, the fingerprint comprising a reduce-bit representation of the media signal; determining information associated with the fingerprint or the media signal; and causing a text message to be sent to a mobile device representing at least a portion of the information. Of course, other methods and combinations are described and claimed as well.
