Application ID: 13310092

Base Claim:
1. A method to detect video copying, comprising: providing a set of reference data elements derived from a set of reference video frames in a reference video stream; providing a set of query data elements derived from a set of query video frames in a query video stream, each of the query data elements having a corresponding query data element identifier; associating with each of the reference data elements a fingerprint selected from among the query data element identifiers; and determining a similarity measure for the query video stream relative to the reference video stream by: for each snippet of the reference data elements that begins at successively shifted reference data element, identifying a segment associated with each snippet; and identifying one of the snippets as the best matching snippet, based on each snippet's associated segment; wherein the similarity measure for the query video stream relative to the reference video stream comprises at least one characteristic of the best matching snippet's associated segment.

Claim 2:
2. The method defined in claim 1 , further comprising deriving the set of reference data elements from the set of video frames in the reference video stream and deriving the set of query data elements from the set of video frames in the query video stream.
