Vorrichtung für das Überprüfen von Dokumenten mit geschichtlicher Speicherung der Aktivitäten des Prüfers

摘要

A document is created and digitally signed using an author's private key. The signed document is provided to an electronic notary who notarizes (provides a time/date stamp and signs the time/date stamp using the notary's private key) the authors signed document. A reviewer requests and verifies the origin and integrity of the authors signed document using the author's public key. As the reviewer examines the documentary, a log is automatically created. The review log and reviewed document are digitally signed using the reviewer's private key and the signed reviewed document is provided to an electronic notary who notarizes the signed reviewed document. An auditor requests the reviewed document. The auditor verifies the origin and integrity of the document using the notary's public key. The auditor audits the signed review document.
