Abstract:
1. A computer-implemented method for facilitating the identification of media objects exhibiting a device fingerprint produced by a target source device, the method comprising: a) receiving, by a computer system including one or more computers on network, a first set of media objects created by a plurality of source devices, each of the media objects including a device fingerprint produced by the source device which created the media object; b) determining, by the computer system, the device fingerprints for each of the media objects in the received first set of media objects; c) grouping, by the computer system, the device fingerprints determined for each of the media objects based on an analysis of the determined device fingerprints of the media objects, thereby defining groups of one or more device fingerprints; d) determining, by the computer system, a composite group fingerprint for each group of device fingerprints stored, wherein the composite group fingerprint of each group is determined using the one or more device fingerprints of the media objects which are members of the group; and e) storing, by the computer system, the groups of device fingerprints and the determined composite group fingerprint for each group on one or more storage devices.
