Anti-counterfeiting Mark with 3-D Features

Non-Confidential description of the invention

The invention is a mark/label for identifying genuine or counterfeited goods and particularly, to an authenticating mark/label of a visual pattern of a random distribution of multiple, multicolored, three-dimensional elements referred to as “PUF (physically unclonable function)”. The invention relates to a method and a system for identifying genuine or counterfeited products by verifying the image of a 3D-PUF against its encrypted image using a commonly held scanning device. The physically unclonable function images are 3D random, which may be formed by paints, clay, nail polish etc. The pattern generated has tactile depth feature and hence the end buyer may detect whether it is produced by the described method or simply it is a 2-D image produced by a counterfeiter.
