Large-Scale MPC: Scaling Private Iris Code Uniqueness Checks to Millions of Users

arXiv:2405.04463v1 Announce Type: new
Abstract: In this work we tackle privacy concerns in biometric verification systems that typically require server-side processing of sensitive data (e.g., fingerprints and Iris Codes). Concretely, we design a solution that allows us to query whether a given Iris Code is similar to one contained in a given database, while all queries and datasets are being protected using secure multiparty computation (MPC). Addressing the substantial performance demands of operational systems like World ID and aid distributions …
