Many institutions and organizations require nostrification and verification
of qualification as a prerequisite for hiring. The idea is to recognize the
authenticity of a copy or digital document issued by an institution in a
foreign country and detect forgeries. Certificates, financial records, health
records, official papers and others are often required to be attested from
multiple entities in distinct locations. However, in this digital era where
most applications happen online, and document copies are uploaded, the
traditional signature and seal methods are obsolete. In a matter of minutes and
with a simple photo editor, a certificate or document copy may be plagiarized
or forged. Blockchain technology offers a decentralized approach to record and
verify transactions without the need for huge infrastructure investment. In
this paper, we propose a blockchain based nostrification system, where awarding
institutions generate a digital certificate, store in a public but permissioned
blockchain, where students and other stakeholders may verify. We present a
thorough discussion and formal evaluation of the proposed system.Comment: The Fifth International Conference on Blockchain Computing and
