Abstract

Digitális adathordozó közegen (2) felvett digitális adatokhoz valóhozzáférés egy első dekódoló kulcsot (Kf) tartalmazó integrált áramkörhasználatával történő korlátozására vonatkozó eljárás során azadathordozó közeg (2) kötetleírójának (V) legalább egy elemét egymegfelelő kódoló kulccsal (Kf) kódolják, a kódolt kötetleíró (V)elemeket a kódolatlan adatokkal együtt az adathordozó közegre (2)rögzítik, és az adathordozó közeghez (2) történő hozzáférés során azintegrált áramkör első dekódoló kulcsát (Kf) használják a kötetleíró(V) kódolt elemeinek a dekódolásához, és ezeket olvasóegységbe (5)táplálva lehetővé teszik a kódolatlan adatok olvasását az adathordozóközegről (2) vagy írását az adathordozó közegre (2). Az eljárásmegvalósítása során használt digitális adathordozó közeg (2) ésintegrált áramkör előállítására vonatkozó további eljárás során azadathordozó közeggel (2) társított kötetleíró (V) legalább egy elemétegy első kulcs segítségével kódolják és a kötetleíró (V) dekódolásáhozszükséges első kulcs ekvivalensét az adathordozó közeggel (2)társított integrált áramkörben eltárolják.
