From The Inquirer.

MOVIE INDUSTRY BOFFINS have come up with another weapon in the war against toe-rags who sneak video cameras into cinemas and make crappy copies of blockbuster movies to sell at car boot sales.

Video watermarking has been around for a while now but this technology can only reveal in which cinema a recording was made. The latest invention goes one step further and can tell investigators exactly which seat the cammer was sitting in to an accuracy of 44cm.
