Abstract
_(UNA DISPOSICION PARA DESTRUIR AUTOMATICAMENTE POR BORRADO EL CONTENIDO DE INFORMACION EN MEMORIAS DE DATOS Y MEMORIAS DE PROGRAMA . CONSISTE EN DOTAR A LA BASE DE DATOS DE UN BOTON DE EMERGENCIA QUE CUANDO ES ACTIVADO PROPORCIONA IMPULSOS ELECTRICOS A UN CIRCUITO ELECTRONICO QUE EN PRIMER PASO BORRA TODA LA INFORMACION DE DATOS CONTENIDA EN LA BASE Y EN UN PASO POSTERIOR BORRA TODA LA INFORMACION DE PROGRAMAS CONTENIDA EN LA BASE DE DATOS. CUANDO LA INFORMACION HA SIDO BORRADA, EL CONTENIDO DE LAS CINTAS O MEMORIAS DE DISCO, NO PUEDE SER LEIDO EN OTRAS COMPUTADORAS Y LA BASE DE DATOS NO PUEDE EMPLEARSE PARA DIFUNDIR FALSA INFORMACION.
