Abstract

Se proporcionan un sistema y un procedimiento de enmascaramiento basado en la preservación de formatos, implementado por ordenador. El sistema obtiene un primer conjunto de letras y una clave privada, y cifra el primer conjunto de letras para obtener una lista de letras cifradas, usando el primer conjunto y la clave privada. La lista de letras cifradas comprende un conjunto de letras cifradas. Se genera una correlación dinámica en base a las letras cifradas, que incluye una o más claves, siendo cada clave específica para una letra en el primer conjunto de letras. Se calcula una posición de cada una de las letras enmascarables en un segundo conjunto de letras, usando la correlación dinámica, y se realiza el enmascaramiento de las letras enmascarables, en base a la posición de cada una de las letras enmascarables, para obtener datos enmascarados, usando la correlación dinámica.
