Abstract:Private Information Retrieval (PIR) protocols allow a user to fetch data from a server-hosted database without disclosing which specific item was retrieved. In singleserver PIR schemes, privacy is maintained through computational hardness assumptions, with recent works optimizing for diverse use cases while balancing communication and computational efficiency. Although early PIR schemes were prohibitively inefficient, recent work demonstrates that it is possible to make PIR fast enough for practical use. While theoretical advances show notable efficiency improvements, thorough testing of modern methods on large, real-world datasets that are actively used remains crucial to confirm their practical applicability. This paper assesses the efficiency of modern PIR systems, namely SimplePIR, using a large real-world dataset widely adopted in applications, Open Food Facts.
