A self-sovereign way to exchange educational credentials

9 pagesPublished: August 9, 2023


In a time of ever-increasing digital transformation, where the amount of data transferred and verified in digital form has vastly increased, new specifications have been released, enabling the exchange of educational credentials in a privacy-respecting manner while maintaining the anonymity of the contributing parties. Hereafter a model is described for educational credentials exchange, built upon the latest W3C and OpenID Connect specifications for Verifiable Credentials and Verifiable Presentations. These emerging technologies and specifications drive the digital transformation towards Web 3.0, while universities can leverage these to provide students and graduates with a secure and self-sovereign method of sharing digital credentials, simplifying the diploma verification process necessary for job applications or when pursuing post-graduate studies. This model encompasses the core principles the next version of the digital diplomas platform of the Greek HEIs (eDiplomas) is based on.

Keyphrases: diplomas, educational credentials, Verifiable Credentials, Verifiable Presentations, Web3.0
