Abstract: 문서들 및 그 내용을 인증하기 위한 시스템 및 방법에 관한 것이다. 사전결정된 고유 문서 식별자(도2) 및 적어도 하나의 보안 기능(도2)을 가지는 복제방지 문서 기록 매체가 제공된다. 기록 매체는 그 이후 통상적으로 문서들 사이에서 변동하는 문서 내용(도2)이 각인된다. 문서 내용은 관련 문서 식별자에 의해 인덱스된 데이터베이스에 저장된다. 문서는 보안 기능을 검토하고 상기 저장된 문서 내용을 인지된 문서 내용과 비교하여 인증될 수 있다. 시스템은 식별된 기록 매체의 판매, 데이터베이스 내 정보의 기록, 온라인 인증 거래, 문서 검증 및 복제 식별에 대한 감별 회계, 각인 장치, 인증장치 등을 포함하는 상업적 개발을 위한 다수의 기회들을 제공한다. 시스템은 물리적 및 논리적 보안 모두를 제공함으로써 우발적 수단을 통한 귀중한 문서들의 복제를 방지한다.
