Abstract
This invention is concerned with the automatic detection of counterfeit documents, particularly checks and currency, through the analysis of images. The method relies on the production of profiles which represent the characteristics of authentic documents and their comparison with similarly extracted profiles from putative authentic documents. In one implementation involving the mass processing of checks the authentic profiles are continuously updated by analysis of large numbers of contemporarily processed checks.
