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

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
