Abstract

LA INVENCION DESCRIBE UN SISTEMA DE ALMACENAMIENTO Y RECUPERACION DE DATOS DE ALTA SEGURIDAD QUE COMPRENDE UNA NUEVA TARJETA DE DATOS DE POCO COSTE, GRABADA POR LASER, QUE PUEDE SER LEIDA Y EN LA CUAL ES POSIBLE ESCRIBIR MEDIANTE UNA INTERFAZ DE ACOPLAMIENTO CAPACITIVO. ESTA TARJETA COMPRENDE VARIOS PRIMEROS Y SEGUNDOS ELECTRODOS COLOCADOS COMO UN TABLERO DE AJEDREZ SOBRE UN SUBSTRATO NO CONDUCTOR. VARIOS ENLACES CONDUCTORES ESTAN INTERCONECTADOS ENTRE PRIMEROS Y SEGUNDOS ELECTRODOS CONTIGUOS A LA TARJETA. LA CONFIGURACION EN TABLERO DE AJEDREZ DE LAS TARJETAS PERMITE QUE CADA PRIMER ELECTRODO PUEDA CONECTARSE HASTA 3 O MAS ELECTRODOS. SE DISPONE DE UN MODULO DE INTERFAZ QUE PUEDE DIRIGIR SELECTIVAMENTE CADA PRIMER ELECTRODO Y CUALQUIER SEGUNDO ELECTRODO CONTIGUO. MEDIANTE ESTE SISTEMA, SE PUEDE ALMACENAR UNA MAYOR CANTIDAD DE INFORMACION SOBRE UNA TARJETA. ESTE INCREMENTO DE LA INFORMACION ALMACENADA RESULTA UTIL PARA PROPORCIONAR UN ALTO NIVEL DE PROTECCION CONTRA LA PRODUCCION DE TARJETAS FALSIFICADAS.
