Abstract

A method and apparatus for verifying the authenticity of a document relative to a previously programmed document are disclosed. The method provides a broadband light source; illuminates a document with the light source; collects reflected light (104); converts it into a corresponding electrical signal or signals;
digitizes the electrical signal (116); and prepares a spectral signature of the document for further analysis. The method also provides for comparing (120) a previously programmed and stored spectral signature to the spectral signature of a test document using a matching value to indicate whether the test document is authentic or not.
