Abstract
Método y sistema de verificación automática de la autenticidad de documentos. El método comprende escanear (306) un documento a verificar en el espectro de luz visible y ultravioleta; detectar en el documento escaneado marcas de agua digital impresas con tinta visible y ultravioleta; desencriptar dichas marcas, obteniendo un identificador de marca ultravioleta y un identificador de marca de datos variables; realizar una validación (318) del porcentaje de marca mediante la comprobación de la presencia de la marca de agua digital en diferentes regiones del documento escaneado; comparar los identificadores de marca obtenidos con identificadores de marca almacenados en una base de datos (108); y determinar la validez del documento en base a dicha comparación. La invención permite la comprobación automática de la validez de los datos impresos en el documento, disminuyendo la posibilidad de que un documento sea falsificado, modificado o alterado total o parcialmente sin ser detectado.Method and system for automatic verification of the authenticity of documents. The method comprises scanning (306) a document to be verified in the visible and ultraviolet light spectrum; detect digital watermarks printed with visible and ultraviolet ink on the scanned document; decrypting said marks, obtaining an ultraviolet mark identifier and a variable data mark identifier; performing a mark percentage validation (318) by checking the presence of the digital watermark in different regions of the scanned document; comparing the obtained brand identifiers with brand identifiers stored in a database (108); and determining the validity of the document based on said comparison. The invention allows the automatic verification of the validity of the data printed on the document, reducing the possibility that a document will be forged, modified or totally or partially altered without being detected.
