2. Privacy-ABCs
• Benefits of Privacy-ABCs
– Privacy-ABCs are by default untraceable (no user-tracking)
– Enable minimal disclosure (user reveals only the necessary information)
– User can chose to stay anonymous or generate (unlimited number of)
pseudonyms
– Advanced security (no sharing of credentials, device-binding for extra
protection)
• ABC4Trust objectives: A common, unified architecture for ABC systems to
enable
– Comparing their respective features
– Combining them on common platforms – reference implementation – 2 pilots
– “Lock-In” free usage of ABC systems
• Raise trust in privacy-ABC technologies

3. ABC4Trust - About
• Scheduled duration: November 2010 – February2015
• Funding: The ABC4Trust project receives research funding from the European
Union's Seventh Framework Programme under grant agreement n° 257782 as part
of the “ICT Trust and Security Research” theme.

5. Pilot Applications
• Norrtullskolan School, Söderhamn, Sweden
• School internal social network for communication
among pupils, teachers, and personnel
• Sept 2013 – Dec 2013
• University of Patras, Greece
• Course ratings conducted anonymously without
lecturers knowing participants’ identities
• Conduct polls based on attendance
• Oct 2013 – Jan 2014

6. Privacy-ABCs and eIDs
• eID cards a gateway to personal information with risks
to the privacy of citizens
– Build privacy-respecting architectures that prevent tracking of
the citizen
• Achieving international interoperability is an important
goal
– Build privacy preserving solutions that can be deployed for
trans-border uses within the EU

7. Challenges ahead
• Address usability issues
– innovative tools, such as “virtual care-takers,” to empower users make
decisions that they cannot understand or evaluate properly
• Address engineering problems
– integrating privacy technologies on large scale deployments is still ill
understood
– examine methods of evaluation, criteria and metrics
• Address continuously new data collection practices and data
flows
– Data treated by cloud-based applications
– Sensors that collect personal information
