Abstract: Methods, systems, and media for transforming fingerprints to detect unauthorized media content items are provided. The method comprises: receiving criteria relating to an application of a circumvention technique to one or more video content items, wherein the criteria includes abuse criteria that describes the circumvention technique and a transform for use with the one or more video content items in which the circumvention technique was applied; generating an abuse query that includes at least a portion of the abuse criteria that describes the circumvention technique; determining from a plurality of video content items, a subset of video content items responsive to the abuse query; applying, for each video content item in the subset of video content items, the transform to each video content item to obtain a transformed video content item; generating, for each transformed video content item, a fingerprint that represents the transformed video content item; and comparing the fingerprint of the transformed video content item to a plurality of fingerprints associated with reference video content items to determine whether the video content item corresponding to the transformed video content item matches one of the reference video content items.

Abstract: A system and method includes receiving a first segment of a probe media item that is transmitted as a first live-stream of an event. The method includes determining, after a first delay period, whether the first segment of the probe media item is similar to a first segment of a first reference media item that is transmitted as a second live-stream of the event and received subsequent to the probe media item. The method includes determining, after the first delay period, whether a second segment of the probe media item is similar to a second segment of the first reference media item. The method also includes responsive to determining that the first segment and the second segment of the probe media item are respectively similar to the first segment and the second segment of the first reference media item, performing a remedial action in association with the probe media item.
