«The Yivi app is the successor to the IRMA app, the first privacy-friendly digital wallet based on personal attributes. IRMA (renamed to Yivi) was developed by Bart Jacobs with his team at Radboud University in Nijmegen. Jacobs is also chairman of the Privacy by Design Foundation. In 2019, collaboration with SIDN began, with SIDN taking over responsibility for managing IRMA’s backbone, to ensure the technology’s essential continuity and availability. Since the fall of 2024 the Dutch company Caesar Groep takes over from SIDN the further development and management of Yivi, in close cooperation with the Privacy by Design Foundation.»
