Abstract

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.

Claims

1. Method for labeling an object for identification which comprises the steps of:

(a) applying a first mark comprising a hologram to said object which mark is visible to the naked eye; and

(b) applying a second mark to said object which mark is invisible to the naked eye, said second mark being one or more of an ultraviolet radiation (UV) dye which is visible to the naked eye only in the presence of ultraviolet radiation, an infrared (IR) dye which is visible to the naked eye only in the presence of infrared radiation, an ink which displays a measurable electrical resistivity or magnetic property, or a biologic marker.

2. The method of claim 1 wherein said first mark is a hologram which is overprinted with an ink which contains one or more of a UV dye, an IR dye, or a biologic marker.

3. The method of claim 1 wherein two or more second marks are applied to said object.

4. The method of claim 3 wherein said second marks comprise a UV dye and a biologic marker.

5. The method of claim 1 wherein said a fluid housed in a pen creates said second mark.

6. The method of claim 4 wherein said ink is housed in a pen.

7. Method for labeling an object for identification which comprises the steps of:

(a) applying a hologram first mark to said object which hologram mark is visible to the naked eye; and

(b) overprinting said hologram first mark with a second mark which invisible to the naked eye and which comprises an ink which contains two or more of an ultraviolet (UV) dye which is visible to the naked eye only in the presence of UV radiation, an infrared (IR) dye which is visible to the naked eye only in the presence of IR radiation, or a biologic marker.

8. The method of claim 7 wherein said overprinting of said second mark is created from an ink housed in a pen.

9. The method of claim 7 wherein said biologic marker is one or more of a protein, amino acid, DNA, polypeptide, hormone, or antibody.
