Abstract

고유 식별자(OID) 및 관련된 서술 정보(DI)를 포함하는 데이타를 기억하기 위한 방법 및 장치가 개시된다. 제1알고리즘(ALG 1)을 사용하여, 고유 식별자(OID)는 갱신 식별자(UID)로 암호화 되고, 그것은 가역 알고리즘(ALG 2)에 의하여, 관련된 서술 정보(DI)와 함께 기억매체에 레코드(P)로써 기억되는 기억 식별자(SID)로 암호화된다. 선택된 레코드(P)의 기억 식별자(SID)가 새로운 기억 식별자(SID')로 대치되는 경우, 기억 식별자(SID)는 대응하는 갱신 식별자(UID)를 재생성하기 위하여 해독되고, 피리고 그것은 새롭게 변형된 가역 알고리즘(ALG 2')에 의하여 이전의 기억 식별자(SID)를 대치하는 새로운 기억 식별자(SID)로 암호화된다.
