Abstract
A method of identifying an object having coded data identifying a plurality of fiducials on a surface of the object and a random pattern superimposed with the coded data. The random pattern defines a fingerprint for the object. The method includes the steps of: receiving, in a computer system, fingerprint data from a data reader interacting with the surface, the fingerprint data identifying some of the random pattern and a fiducial; using the fiducial to identify a portion of the random pattern; and identifying, using the identified portion of the random pattern, an object identity.
