Abstract

Aparato para la detección de adulteraciones o falsificaciones de documentos u objetos de características similares, realizadas con técnicas de borrados mecánicos o químicos de datos, textos o imágenes escritos o impresos, sobreescrituras para modificar los datos o textos directamente, reemplazos de partes del documento utilizando microcirugías o técnicas similares y reescritura sobre estas partes de nuevos textos o impresión de nuevos textos o datos sobre ellas, reemplazaos de foto, etc. en documentos tales como: Cheques, Pasaportes, Carnets, Licencia de conducir, Cédulas de identificación, Bonos de cancelación de deudas, Facturas, Tarjetas de crédito, etc. falsificaciones de documentos como los anteriormente enumerados por digitalizaciones, impresiones clandestinas, etc. formado por un módulo de escaneo digital de la superficie del elemento en estudio compuesto por una cámara de video,, un conjunto de luces que abarcan desde el espectro infrarrojo hasta el ultravioleta y un conjunto de filtros pasa altos. Un módulo de procesamiento de la imagen obtenida por el módulo de escaneo al fin de mejorar la misma cuando las condiciones de iluminación y/o filtrado son extremas y un módulo de visualización de la imagen obtenida por los dos módulos anteriores. Por medio de combinaciones de estimulación de luz en rangos del espectro lumínico acotados a la aplicación de filtros se puede observar anomalías en la superficie del elemento o la presencia o ausencia de reacciones al estímulo de la luz de las tintas utilizadas para la impresión de los fondos o la impresión o escritura de datos sobre el elemento en estudio.Apparatus for the detection of adulterations or falsifications of documents or objects of similar characteristics, made with mechanical or chemical erasure techniques of written or printed data or texts, overwriting to modify data or texts directly, replacements of parts of the document using microsurgery or similar techniques and rewriting on these parts of new texts or printing of new texts or data on them, photo replacements, etc. in documents such as: Checks, Passports, Carnets, Driver's license, Identification cards, Debt cancellation vouchers, Invoices, Credit cards, etc. forgery of documents such as those listed above for scanning, clandestine printing, etc. formed by a digital scanning module of the surface of the element under study composed of a video camera, a set of lights ranging from infrared to ultraviolet spectrum and a set of high pass filters. An image processing module obtained by the scanning module in order to improve it when the lighting and / or filtering conditions are extreme and an image display module obtained by the two previous modules. By means of combinations of light stimulation in ranges of the light spectrum bounded to the application of filters, it is possible to observe anomalies in the surface of the element or the presence or absence of reactions to the light stimulation of the inks used for printing the funds or the printing or writing of data on the element under study.
