DETERMINATION OF ORIGINALITY OF CONTENT

Video content uploaded from a user, and received at a web-based service, is processed to compute fingerprint data. By reference to the fingerprint data, controlled content included within the received content is identified. A similarity score between the controlled content and the received content is determined. Usage rule data to be applied to the received video content is selected (e.g., based, at least in part, on the determined similarity score), and is applied in governing distribution of the received video content from the web-based service. In some arrangements, the owner of the controlled content is identified, and selection of rule data depends on the identified owner. The owner may have established multiple usage rules, and selection between them may be based, e.g., on a percentage of the controlled content that is included in the received video content. A great variety of other features and arrangements are also detailed.
