Abstract: An example method includes: (a) receiving a set of query fingerprints associated with a media file; (b) comparing the set of query fingerprints to a set of reference fingerprints associated with primary reference media files; (c) identifying first and second subsets of query fingerprints, wherein the first subset of query fingerprints satisfies a first threshold extent of similarity, and wherein the second subset of query fingerprints does not; (d) identifying at least one candidate reference media file of the primary reference media files; (e) comparing the second subset of query fingerprints to a subset of secondary reference fingerprints, wherein the subset of secondary reference fingerprints is based on the identified at least one candidate reference media file; (f) identifying a particular reference media file of the plurality of secondary reference media files; and (g) transmitting an indication that the media file matches the particular reference media file.

Abstract: Link2File, A method to allow computers connected to the Internet to find each other, identify specific files, video and/or audio channels within them and automatically initiate actions (such as peer-to-peer file transfers or video feeds), even when their Internet Protocol (IP) address is reassigned at random by a third-party.
