Abstract

Se da a conocer un metodo y aparato para verificar la autenticidad de un documento en relacion con un documento previamente programado. El metodo proporciona una fuente de luz de banda amplia; ilumina un documento con la fuente de luz; recolecta la luz reflejada (104), la convierte en una senal o senales electricas correspondientes; digitalita la senal electrica (116); y prepara una firma espectral del documento para su analisis adicional. El metodo tambien proporciona la comparacion (120) de una firma espectral previamente programada y almacenada con la firma espectral de un documento de prueba utilizando un valor de concordancia para indicar si el documento de prueba es autentico o no.
