En esta contribución se presenta la implementación experimental un sistema de protección de información basado en el procesamiento óptico y se analiza la fidelidad de la información recuperada cuando hay pérdida de datos durante la transmisión. La información es encriptada empleando una arquitectura óptica de correlador de transformada conjunta y una técnica de codificación de doble máscara de fase. Un usuario autorizado puede recuperar la información original cuando tiene acceso a la información del dato encriptado y de la llave de seguridad; si un intruso puede interceptar la imagen encriptada, pero no accede la información de la llave de seguridad, no podrá acceder a la información contenida en el dato encriptado. La descripción teórica ...
