A method for verifying the authenticity of a document utilizes artifacts
of the printing process. The method includes optically capturing at a
predetermined magnification a first image of an indicia printed on the
authentic document. A corresponding indicia on a document to be
authenticated is optically captured at a predetermined magnification. The
captured images and the printing process artifacts depicted therein are
characterized. Authenticity is verified where the characterization
indicates the captured images are sufficiently identical. An indication
is issued as to whether the document is authentic.
