Abstract

소프트웨어 복사 처리 장치에 관한 것으로, 마스터 기억 매체에 기억된 저작권 보호 소프트웨어를 사용자의 기억매체에 정단하게 복사할 수 있도록 하는 것을 목적으로 한다. 내용 식별자 독취 수단(2)이 마스터 기억매체(1)상의 소프트웨어의 식별자를, 기억매체 식별자 독취 수단(4)이 타겟 기억 매체(3)의 식별자를 각각 독취하고, 복사권 판매를 관리하는 센터(5)로 전송한다. 센터(5)에서는 서명 작성 수단(6)이 전송한 식별자의 정보로부터 서명을 작성하여 사용자에게 전송한다. 전송된 서명은 서명 기록 수단(7)에 의해 타겟 기억 매체(3)에 기입된다. 서명 생성 수단(8)은 센터로 전송된 식별자의 정보로부터 사용자측에서 서명을 작성하고, 그 생성된 서명을 타겟 기억 매체(3)에 기입한 서명과 비교하며, 서명이 일치하는 경우에만 데이타 복사 수단(9)이 마스터 기억 매체(1)의 복사 대상 소프트웨어를 독출하여 타겟 기억 매체(3)로 복사한다.
