Want to find out whether or not something at the street market is a fake? In the future, you might only have to snap a photo with your smartphone. NEC has developed "object fingerprint" technology that compares the tiniest details of an object (such as the metal or plastic grain) with images in a cloud database; if something doesn't look quite right in that cut-rate handbag, you'll know right away. It's useful beyond piracy, too. You could trace the origins of legitimate items, or make sure that repair crews are using the right parts.
