Abstract

PROCEDIMIENTO DE AUTENTIFICACION PARA DOCUMENTOS DE SEGURIDAD. SE BASA EN LA UTILIZACION DE DOS TIPOS DE TINTAS, CONCRETAMENTE DE DOS TINTAS CON FORMULACIONES DIFERENTES, UNA CON PIGMENTOS TRANSPARENTES AL INFRARROJO (TIR), Y OTRA CON PIGMENTOS NO TRANSPARENTES AL INFRARROJO (NOTIR). CON ESTAS DOS FORMULACIONES DE TINTA, SE PROCEDE A REALIZAR DOS IMPRESIONES SUCESIVAS DEL DOCUMENTO, UNA CON CADA TIPO DE TINTA, DE MANERA QUE CUANDO POSTERIORMENTE EL DOCUMENTO SE EXPONE A ANALISIS POR UN DETECTOR DE INFRARROJO ADECUADO, PARTE DE LA IMPRESION RESULTARA VISIBLE POR EL DETECTOR Y OTRA PARTE NO VISIBLE. LA PARTE VISIBLE, POR EL DETECTOR, PODRA AJUSTARSE A CUALQUIER CODIGO APROPIADO, SIN PRACTICAMENTE LIMITACION ALGUNA AL RESPECTO, DESDE UN SIMPLE VOCABLO, COMO POR EJEMPLO EL VOCABLO "ORIGINAL", HASTA UN COMPLEJO CODIGO DE BARRAS QUE PERMITA, CON LA COLABORACION DE UN DESCODIFICADOR, NO SOLO VERIFICAR LA AUTENTICIDAD DEL DOCUMENTO, SINO DETERMINAR EL TRATAMIENTO QUE DEBE DARSE AL MISMO.AUTHENTICATION PROCEDURE FOR SECURITY DOCUMENTS. IT IS BASED ON THE USE OF TWO TYPES OF INKS, SPECIFICALLY TWO INKS WITH DIFFERENT FORMULATIONS, ONE WITH TRANSPARENT PIGMENTS TO THE INFRARED (IRR), AND ANOTHER WITH NON-TRANSPARENT PIGMENTS TO THE INFRARED (NOTIR). THROUGH THESE TWO INK FORMULATIONS, TWO SUCCESSIVE PRINTS OF THE DOCUMENT, ONE WITH EACH TYPE OF INK, ARE CARRIED OUT, SO THAT WHEN THE DOCUMENT IS SUBSTITUTED TO ANALYSIS BY A SUITABLE INFRARED DETECTOR, PART OF THE IMPRESSION WILL BE VISIBLE DETECTOR AND OTHER PART NOT VISIBLE. THE VISIBLE PART, BY THE DETECTOR, MAY BE ADJUSTED TO ANY APPROPRIATE CODE, WITHOUT PRACTICALLY ANY LIMITATION IN THIS REGARD, FROM A SIMPLE VOICE, AS FOR EXAMPLE THE VOCABLE "ORIGINAL", UP TO A COMPLEX OF BARS WITH A PERMIT DECODER, NOT ONLY VERIFYING THE AUTHENTICITY OF THE DOCUMENT, BUT DETERMINING THE TREATMENT TO BE GIVEN TO IT.
