<p>The present invention is addressed to providing a simple, yet reliable method for labeling an object for its verification. Broadly, the method of the present invention for labeling an object for its verification commences with applying to a predetermined location on said object, a mark which creates a permanent impression thereof which is perceptible to the unaided or naked eye and a mark which creates a permanent impression thereof which is imperceptible to the unaided or naked eye, yet which can be determined by mechanical, electrical, and/or biologic means. In prior U.S. Pat. No. 5,194,289 a combination of UV eye and amino acid/protein fragment was used to label objects for their identification. The present invention broadens such dual labeled scheme to include a variety of additional "invisible" labeling techniques. Additionally, the present invention includes the recognition that, in order to stop counterfeiting of records and like consumer goods, a visible mark also must be present on the object. A hologram or other visible indicia would provide the owner (and the copyist) with one level of protection in ascertaining the genuineness of the object. The second means is "invisible" to the owner (and the copyist) and is designed to be difficult (if not impossible) for the copyist to duplicate.</p> |
