EduTAP Common ID - A Standardized Digital Identity Document for HEIs

11 pages•Published: November 6, 2025

Abstract

Universities increasingly seek to transition from physical campus cards to digital solutions. However, in-app implementations often lack interoperability and security. For this reason, this paper proposes the eduTAP Common ID, a standardized digital identity document for Higher Education Institutions (HEIs), aligning with ISO 18013-5 (mDoc) and eduGAIN schemas (eduPerson and SCHAC). By leveraging mobile wallets, we enable HEIs to move toward a harmonized and secure digital identity that is interoperable not only across universities but also with external providers. Building on ISO 18013-5, the proposed HEI Common ID implicitly incorporates privacy-preserving mechanisms such as selective disclosure and informed consent. As a result, the proposed HEI Common ID provides an ideal basis for standardizing a GDPR-compliant, trusted, and globally scalable digital student and staff credential.
