Abstract

Disclosed is a method for labeling an object for its identification. The method comprises applying a selected person'"'"'s fingerprint to said object at a predetermined location upon said object. Next, the predetermined location is exposed to a vaporous agent comprising vapors of a cyanoacrylate ester. The selected person'"'"'s fingerprint or said vapors of cyanoacrylate ester bear a detectable amount of an ultra-violet radiation sensitive dye. Exposing the predetermined location to said vapors create a permanent impression of the fingerprint on the object which impression is perceptible only in the presence of UV radiation. Prime objects for identification in accordance with the method of the present invention include works of art, negotiable instruments, credit card receipts, and like objects.
