Abstract

UN METODO Y UN DISPOSITIVO PARA FACILITAR SIMULTANEAMENTE EL ACCESO AUTORIZADO Y EL ACCESO NO AUTORIZADO RESTRINGIDO A UNA MULTITUD DE SECUENCIAS ALFANUMERICAS, POR EJEMPLO, TARJETAS DE CREDITO, CLAVES DE CODIGOS O SIMILARES. SEGUN ESTE METODO, CADA SECUENCIA CORRECTA (P.E, 5533) ES ENCRIPTADA MANIPULANDOLA MATEMATICAMENTE POR MEDIO DE UNA SECUENCIA DE ENCRIPTACION (7221) COMUN A CADA SECUENCIA CORRECTA, DE MANERA QUE CADA SECUENCIA CORRECTA ES CONVERTIDA EN UN SECUENCIA ENCRIPTADA FICTICIA. LA TARJETA DE CREDITO TIENE UN MEDIO PORTADOR (12-16) PARA LLEVAR Y MOSTRAR LA SECUENCIA FICTICIA. EL DESCIFRADO DE LA SECUENCIA FICTICIA ES LLEVADO A CABO POR UNA MANIPULACION MATEMATICA INVERSA FICTICIA.
