ABSTRACT:
A system and method is provided for securely duplicating digital documents of disparate types, such that there is a cryptographically secure link between the duplicate and the original. The system also provides each document with a serial number that is both sequential with all other copied documents and cryptographically linked with the document itself, and which includes verifiable proof against tampering and modification. The system further produces copies of documents in a canonical format suitable for indexing and searching using automated processing tools.
