MySpace has launched “Take Down, Stay Down,” a new filtering technology that prevents users from posting the same copyrighted video that has been removed in the past. When a takedown order is issued, MySpace takes a fingerprint of the clip and stores it in a database. When someone uploads a new clip, it’s compared against the database to ensure it’s not one of those copyrighted clips. Meanwhile, YouTube keeps saying it’s close to launching Claim Your Content, it’s own filtering technology.
MySpace’s video page. When you upload a clip, it warns in red type, “If you upload porn or unauthorized copyrighted material, your MySpace.com account will be deleted.”
