Abstract
EN UN METODO Y APARATO PARA LA AUTENTIFICACION DE DOCUMENTOS, AL MENOS UNA PEQUEÑA ZONA (22) DE UN DOCUMENTO (12) A VERIFICAR, ES DETECTADA POR UN ESPECTROSCOPIO (26) Y LA INTENSIDAD DE LA LUZ EN MULTIPLES (EJ.: 50) PUNTOS ESPECTRALES SE MIDE POR MEDIO DE UNA SERIE DE FOTODIODOS (30). LAS SEÑALES RESULTANTES SE DIGITALIZAN EN UN CONVERSOR ANALOGICO-DIGITAL (38) Y LOS DATOS RESULTANTES SE ALMACENAN. ESTOS DATOS SON ANALIZADOS DESPUES POR UN ANALISIS DISCRIMINATORIO, EN EL QUE SE MULTIPLICAN LOS VALORES DE INTENSIDAD, TRATADOS COMO COMPONENTES DE UN VECTOR, POR UNO O MAS CONJUNTOS DE COEFICIENTES DE PESO (FUNCIONES DISCRIMINATORIAS) PARA PROPORCIONAR AL MENOS UN CONJUNTO DE VALORES DE FUNCIONES DISCRIMINATORIAS. SE COMPARA UNA MEDIDA DE DISTANCIA ENTRE ESTE CONJUNTO DE VALORES Y EL CENTRO DE GRAVEDAD DE UN CONJUNTO DE VALORES CORRESPONDIENTES PARA DOCUMENTOS GENUINOS, CON UN VALOR DEL UMBRAL PARA DETERMINAR LA AUTENTICIDAD DEL DOCUMENTO (12).
