20140041054, "Attestation of possession of media content items using fingerprints," assigned to Microsoft.
A method for verifying a user's access to a content media item includes discovering at least one content item stored on a storage medium associated with a client device. A fingerprint of a selected portion of the media content item is obtained. The selected portion is a portion less than an entirety of the media content item. The fingerprint is communicated to an online service. Access to an online copy of the media content item is received if the fingerprint matches a known fingerprint of a media content item available to the online service
20140037133, "System, method & computer program product for video fingerprinting," assigned to The University Court of the University of St. Andrews
A method for fingerprinting a video involving identifying motion within the video and using a measure of the identified motion as a fingerprint. Once videos are fingerprinted, these fingerprints can be used in a method for identifying video. This involves creating a motion fingerprint for unidentified videos; comparing the fingerprints of the known and unknown videos, and identifying whether the unknown video is a copy of the known video based on the step of comparing.
