System and method for media fingerprint indexing

A system, comprising:

• one or more processors;
• a memory coupled to one or more processors, wherein the memory stores program instructions executable by the one or more processors to implement a media fingerprint and indexing service, wherein said media fingerprint and indexing service is configured to:
• generate a fingerprint for a media file, wherein the fingerprint comprises a plurality of frames, each frame corresponding to a different time segment of the media file, wherein each value of each frame has a confidence value indicating the accuracy of that value;
• for each frame of the fingerprint, combine the confidence values for that frame to produce a confidence score for each frame of the fingerprint;
• select a portion of the plurality of frames of the fingerprint having confidence scores greater than a remaining portion of the plurality of frames of the fingerprint;
• generate an index based on the position of each selected frame in the fingerprint.

A non-transitory computer-accessible storage medium storing program instructions computer-executable to implement a media fingerprint and indexing service, configured to:

• generate a fingerprint for a media file, wherein the fingerprint comprises a plurality of frames, each frame corresponding to a different time segment of the media file, wherein each value of each frame has a confidence value indicating the accuracy of that value;
• for each frame of the fingerprint, combine the confidence values for that frame to produce a confidence score for each frame of the fingerprint;
• select a portion of the plurality of frames of the fingerprint having confidence scores greater than a remaining portion of the plurality of frames of the fingerprint;
• generate an index based on the position of each selected frame in the fingerprint.
