An Invisible Technology May Slow Piracy

“Hollywood is considering whether the technology, developed by a New Jersey company, could help reduce video piracy, which the major studios contend is costing them more than $3 billion in worldwide revenue. The secret code imprinted on a movie would not stop film pirates from spreading their grainy counterfeits on the Internet, but it would reveal the identity of the last legitimate user to industry sleuths. The developers claim their method will improve on existing techniques to create such a code, known as a “watermark” after printing, that can only be seen under certain conditions.”
