Abstract
A method and apparatus for forestalling counterfeiting is disclosed which allows a counterfeit document to be identified relatively easily by an average person. The present invention employs a fluid jet applicator to record a unique, random pattern on each of a set of documents (e.g., paper currency, corporate or government bonds or any other document or important paper). Thus, a fluid jet applicator is controlled to produce a truly unique pattern on a set of original documents. Any counterfeiter who merely copies one (or a number) of the genuine documents would be left with a plurality of identical (i.e., non-unique) documents which may then be readily identified by a recipient as not being genuine.
