Using digital fingerprints to associate data with a work

摘要

A computing device, during sampling or playback of a work, receives a command to associate data with the work at a particular point in the work. The computing device generates a digital fingerprint of a segment of the work, wherein the segment corresponds to the particular point in the work. The computing device then associates the data with the digital fingerprint.
