Pseudonymization Service for X-Road eGovernment Data Exchange Layer
Abstract. Pseudonymization is sometimes used as a light-weight alternative to fully cryptographic solutions, when information from different data sources needs to be linked in a privacy-preserving manner. In this paper, we review several previously proposed pseudonymization techniques, point out their cryptographic and design flaws. As a solution, we have developed a simple pseudonymization framework based on X-Road, a unified database access layer serving as the basis for most eGovernment services developed in Estonia. Our solution has been fully implemented and benchmarking results together with the security analysis are presented to conclude the paper.
