Abstract

I en kodingsfremgangsmåte for kryptering av informasjon som er verdt å beskytte på et holografisk datalagringsmedium, blir en gjenstand for informasjon (I; I1, I2) som skal krypteres konvertert til et grafisk databilde (D1, D2), som igjen blir konvertert til et hologram for å skrive det holografiske datalagringsmediet (4) dermed. Oppfinnelsen gjør det mulig for hologrammet å bli endret grafisk før skriving av det holografiske datalagringsmediet (4). Som et resultat av måt en i hvilken hologrammet blir endret grafisk, blir kryptering som er mindre utsatt for feil oppnådd på en enkel måte, som representerer økt motstand mot et parallelt rå-kraftangrep.
