Abstract
En fremgangsmåte for kryptering av multimediadata omfatter innlegging av en krypteringsindeks (18) i en bestemmelses- datablokk (10, 30) for de nevnte data, hvor indeksen indikerer en krypterings- algoritme som skal benyttes. Som reaksjon på krypteringsindeksen utvelges en krypteringsalgoritme i bestemmelsesdata- blokken (10, 30) fra et antall slike algoritmer. Multiraediadataene krypteres ved benyttelse av den utvalgte kryp- teringsalgoritme. Forskjellige andre inn- legginger i bestemmelsesdatablokken (10, 30) til hvilken multimediadataene er til- delt, frigjør en dekrypteringsanordning og tillater rask tilgang til en databank av krypterte multimediadata, og en kunde- og dataspesifikk anvendelse av multi- mediadataene samtidig som opphavsretter respekteres.
