Verifying digital academic credentials securely

Sector: Tertiary sector · Industry: Government agencies and public administration · Organisation: Infocomm Media Development Authority (IMDA), Government Technology Agency (GovTech) Singapore, National University of Singapore (NUS) · Maturity level: Production

The Infocomm Media Development Authority and GovTech Singapore launched an open-source Ethereum framework with partner universities to issue tamper-proof educational credentials. Academic degrees and transcripts are cryptographically signed and issued as digital files whose authenticity can be instantly checked without contacting the issuing university. Leading institutions such as the National University of Singapore have adopted the platform to provide permanent verifiable records to graduates.

Documentation status

Description

The Infocomm Media Development Authority and GovTech Singapore operate a platform for tamper-proof verification of educational qualifications. Instead of physical certificates, graduates receive cryptographically signed files whose authenticity can be checked within seconds via a central web portal. The underlying blockchain guarantees that documents cannot be altered or retroactively manipulated unnoticed after issuance.

The OpenCerts framework was developed as an open-source platform to effectively curb the growing market of forged educational certificates. After an initial pilot project in 2018, the system was made accessible to educational institutions across Singapore, with organisations such as the National University of Singapore among the first production users. Technically, the certificates are structured as JSON documents, cryptographically hashed, and matched with the Ethereum smart contracts of the respective educational institution. No personal clear data is stored on the blockchain; only checksums and issuer identities are managed, thus meeting data protection requirements. Employers and verification offices can validate certificate files by drag-and-drop in a web interface without requiring special software or blockchain expertise.

Perspectives

B2B — organisations perspective

Companies and authorities can verify application documents in the recruitment process without any time delay. Direct validation via standardised interfaces or web forms eliminates costly enquiries to university registrars and minimises the risk of incorrect decisions due to manipulated educational certificates.

B2C — consumers perspective

Graduates receive permanent and unrestricted access to their official certificates in digital form. They can flexibly forward these files to any employer or further education institution without having to request costly duplicate copies or notarised certifications.

Employees perspective

Staff in examination offices and HR departments are relieved from repetitive validation tasks. Instead of manually certifying documents or issuing written confirmations, a standardised digital verification process suffices, reducing misjudgements and bureaucratic overhead.

Technology foundation

The solution uses the public Ethereum blockchain for decentralised anchoring of cryptographic integrity proofs and smart contracts. Smart contracts manage identity registers of authorised educational institutions as well as status information on the validity and revocation of certificates, while the actual personal certificate data remain off-chain as cryptographically signed files.

Implementation examples

Nationwide verification of digital university certificates

The growing spread of forged educational documents and the lengthy, paper-based verification processes for employers made a trustworthy, decentralised solution necessary.

IMDA and GovTech Singapore jointly introduced a production Ethereum framework with the National University of Singapore for issuing and verifying tamper-proof educational qualifications.

As part of the government initiative, IMDA, GovTech and participating universities such as the National University of Singapore provided the OpenCerts system to cryptographically anchor certificates on Ethereum. Graduates receive a structured file whose validity and issuer identity can be verified via a public web portal. After a pilot phase in 2018, the platform went into regular production operation and forms the basis for nationwide proof of academic qualifications.

Elimination of bureaucratic verification effort between employers and universities while simultaneously protecting against subsequent manipulation of degree certificates.
