The Privacy by Design Foundation in general aims to improve the development and the use of open, privacy-friendly and secure software. More in particular, the foundation focuses on the development, roll out, and actual usage of its own system IRMA, an abbreviation of I Reveal My Attributes. With IRMA people can prove in a privacy-friendly and secure manner various personal properties (attributes) about themselves (such as: I’m older than 18), without revealing any other non-relevant information.
