dc.description.abstract | Los sistemas de protección de información basados en procesadores ópticos y que emplean una técnica de codificación de doble máscara aleatoria de fase permiten el manejo seguro de los datos, pero su recuperación no está libre de ruido. Si bien la seguridad del sistema es provista por el procesador óptico que habilita encriptar la información, en este trabajo se demuestra que la recuperación libre de ruido es posible mediante la inclusión de la codificación de respuesta rápida, sin alterar el proceso de protección de datos. La información que se desea proteger es previamente convertida en un código de respuesta rápida o código QR, y posteriormente el código es encriptado ópticamente. El código QR recuperado contendrá el ruido habitual producido por el uso de las máscaras aleatorias de fase y el procesamiento óptico-digital involucrado en el proceso. Finalmente, al escanear el código QR desencriptado se puede recuperar la información original completamente libre de ruido. Se incluye la descripción teórica del procesador óptico y se presentan resultados experimentales que demuestran la validez y aplicabilidad del sistema de protección. | spa |
dc.description.abstract | The information protection systems based on optical processors, employing a double random phase mask encryption technique, allow data securely handling, but the recovery is not noise-free. Although the system security is provided by the optical processor enabling the information encoding, we demonstrate in this contribution that noise-free recovery is indeed possible by including the quick response coding, without altering the data protection process. The information to be protected is first converted into a quick response code or QR code, and then this code is optically encrypted. The decrypted QR code exhibits the usual noise produced by the random phase masks along with the involved opto-digital processing. Finally, when scanning the decrypted QR code we recover the original information without noise. We include the theoretical description of the optical processor, as well as we show experimental results that corroborate the validity and applicability of the security system. | eng |
