Whenever users receive or transfer a copy of any of a set of documents, prior verification of the document is enforced by an administrative system, which associates verification metadata with the copy. As each copy is itself copied, possibly modified, and transferred, updated verification metadata is included with the previous verification metadata to form a verification lineage chain, which can later be examined to determine the circumstances of any verification failure. Documents are preferably verified by comparing the digital signature of the current copy with the signature of a reference copy. Documents may be signed by submitting them as transactions to a blockchain, with the blockchain receipt comprising the digital signature of the respective document.
