Sažetak
When archiving a digitally signed document an issue arises once the certificate used in the signature expires (or possibly the certificate authority stops functioning). Once this happens, the signature can no longer be confirmed and tampering with the document is possible. This paper presents a model for long- term preservation of digitally signed documents using blockchain technology. The authors propose a semi-open system in which only certain institutions can create new entries but any interested party can view the records and confirm their authenticity.
