Trustworthy, yet privacy-preserving authentication is necessary to enable long-term and lifelong privacy for users. Attribute-based credentials offer a solution allowing strong authentication while the user may remain anonymous towards the relying party and without the identity provider learning to know about the websites visited or services deployed by a user. The technology to deploy attribute-based credentials is available with IBM's Identity Mixer and Microsoft's U-Prove. The EC-funded project ABC4Trust now takes up the heritage of the PRIME and PrimeLife projects and will deploy systems using attribute-based credentials in actual production pilots and deliver open reference implementations.

PrimeLife and ABC4Trust organize a joint tutorial explaining the basics of the technology, its potential spheres of application for privacy-enhancing technologies and some building blocks of the underlying cryptography. The tutorial will be held in Rüschlikon (near Zurich) on Friday June 10, 2011 and hosted by IBM Research Zurich.

Tutorials will be given by expert researchers from Microsoft and IBM, presenting a common view on Privacy-ABC technologies that encompasses both the U-Prove and Identity Mixer technologies.
