Abstract

En un procedimiento de codificación para el cifrado de información valiosa en un medio de almacenamiento de datos holográficos, un elemento (I; I1, I2) de información que va a cifrarse se convierte en una imagen (D1, D2) de datos gráficos que a su vez se convierte en un holograma con el fin de escribir el mismo en el medio (4) de almacenamiento de datos holográficos. La invención hace que el holograma se modifique gráficamente antes de la escritura en el medio (4) de almacenamiento de datos holográficos. Como resultado de la manera en la que el holograma se modifica gráficamente, se consigue de manera sencilla un cifrado que es menos susceptible a fallos, lo que representa una mayor resistencia frente a un ataque de fuerza bruta en paralelo.
