Abstract

An anti-counterfeiting method and apparatus causes a first mark to be produced on an object such as a pill in a package and then causes a second mark to be produced on said object while also producing said second mark on the plastic package cover over said object. A first laser beam producing means produces a first laser beam, preferably in the IR spectrum, and produces said first mark on the object when the beam passes through said cover. A second laser beam producing means produces a second laser beam preferably in the UV spectrum. The second laser beam also passes through said cover and produces said second mark superimposed on said first mark on said object. The second mark is always different from said first mark. Continued passing of said second beam through said cover causes said cover cloud up and form said second mark on said cover also. Accordingly, it is possible to determine if said object is in its original packaging by comparing the second mark on the object with the mark on the plastic cover and, if the objects are separated from their original packaging, when and where the object was made from the information embedded in said second mark on said object.
