FiveEyes: Cryptographic Biometric Authentication from the Iris
Paper 2024/100 , Gonzaga University , University of Connecticut , Adelphi University , University of Connecticut , University of Connecticut Despite decades of effort, a stubborn chasm exists between the theory and practice of device-level biometric authentication. Deployed authentication algorithms rely on data that leaks private information about the biometric; thus systems rely on externalized security measures such as trusted execution environments.
Private Eyes: Zero-Leakage Iris Searchable Encryption
Paper 2023/736 Private Eyes: Zero-Leakage Iris Searchable Encryption , Boston University , University of Connecticut , University of Connecticut , University of Connecticut , University of Connecticut Abstract Biometric databases are being deployed with few cryptographic protections. Because of the nature of biometrics, privacy breaches affect users for their entire life. This work introduces Private Eyes, the first zero-leakage biometric database.
Multi Random Projection Inner Product Encryption, Applications to Proximity Searchable Encryption for the Iris Biometric
Paper 2020/1174 Multi Random Projection Inner Product Encryption, Applications to Proximity Searchable Encryption for the Iris Biometric Abstract Biometric databases collect people’s information and allow users to perform proximity searches (finding all records within a bounded distance of the query point) with few cryptographic protections. This work studies proximity searchable encryption applied to the iris biometric.
Impossibility of Efficient Information-Theoretic Fuzzy Extraction
Paper 2023/172 Impossibility of Efficient Information-Theoretic Fuzzy Extraction , University of Connecticut , University of Connecticut , University of Connecticut Abstract Fuzzy extractors convert noisy signals from the physical world into reliable cryptographic keys.
