Music and movie rightsholders regularly encourage Google to scrub more piracy sites out of its search engine results. Now Disney may be exploring the feasibility of building this kind of technology itself. TorrentFreak reports on a patent awarded to Disney for an “online content ranking system based on authenticity metric values for web elements” which could “enable the filtering of undesirable search results, such as results referencing piracy websites”. In other words, downranking sites that have good SEO but lots of pirated content by using an “authenticity index” that includes factors like trademarks, copyrighted material and domain name registrations. There are some problematic angles to this: Disney’s suggestion that a Wikipedia page for a film may come below the movie’s official website is a debate in itself, for example.
