Re/code: A year after it started making a big push into video, Facebook is acknowledging it has a video piracy problem. And it says it’s going to start fixing it. Facebook is rolling out a “video matching technology” that will let content owners tell the social media giant that a video clip belongs to them, and take it down if it’s not supposed to be there. It’s the first step to creating the equivalent of YouTube’s content ID system, which the video giant built up over years as a response to its own copyright/piracy problems.
