Tech companies race to create filtering tools

One of the biggest growth businesses in tech right now is creating technology to identify copyrighted video and audio clips. Last week, MySpace signed a deal with Audible Magic to begin to filter out copyrighted clips uploaded by its users. YouTube, which has promised its own technology, is weeks behind its promised launch date. In the meantime, over a dozen companies are racing to create tools that not only can identify audio files, but video as well. “This is capable of helping the film and TV studios comprehensively protect their works,” said Vance Ikezoye, CEO of Audible Magic. “This could put the genie back in the bottle.”
