Abstract

Various authentication systems may benefit from detection of counterfeits. More particularly, certain authentication systems may benefit from a counterfeit detection scheme applicable to paper surfaces that can employ mobile cameras, such as the cameras associated with mobile phones. A method, according to certain embodiments, can include illuminating a surface of an item with a lighting source of a device. The method can also include capturing a plurality of images of the surface by a camera of the device during the illumination of the surface. The method can further include authenticating the item based on the plurality of images.
