Towards a Framework for Benchmarking Privacy-ABC Technologies

Technologies based on attribute-based credentials (Privacy-ABC) enable identity management systems that require minimal disclosure of personal information and provide unlinkability of user's transactions. However, underlying characteristics of and differences between Privacy-ABC technologies are currently not well understood. In this paper, we present our efforts in defining a framework for benchmarking Privacy-ABC technologies, and identifying an extensive set of benchmarking criteria and factors impacting such benchmarks. In addition, we identify important challenges in the adoption of Privacy-ABC technologies, indicating directions for future research.
