Privacy Leakage in Fuzzy Commitment Schemes
Abstract In 1999 Juels and Wattenberg introduced the fuzzy commitment scheme. Fuzzy commitment is a particular realization of a binary biometric secrecy system with a chosen secret key. Three cases of biometric sources are considered, i.e. memoryless and totally-symmetric biometric sources, memoryless and input-symmetric biometric sources, and memoryless biometric sources. It is shown that fuzz...
متن کاملImage Compression in Iris-Biometric Fuzzy Commitment Schemes
Template protection targets privacy and security risks caused by unprotected storage of biometric data. Meeting properties of irreversibility and unlinkability template protection systems can be applied to secure existing records within biometric databases, i.e. without re-enrollment of registered subjects. The National Institute of Standards and Technology (NIST) demonstrated that iris recogni...
متن کاملIris-Biometric Fuzzy Commitment Schemes under Image Compression
With the introduction of template protection techniques, privacy and security of biometric data have been enforced. Meeting the required properties of irreversibility, i.e. avoiding a reconstruction of original biometric features, and unlinkability among each other, template protection can enhance security of existing biometric systems in case tokens are stolen. However, with increasing resolut...
متن کاملSystematic Construction of Iris-Based Fuzzy Commitment Schemes
As a result of the growing interest in biometrics a new field of research has emerged entitled Biometric Cryptosystems. Only a small amount of work, which additionally tends to be custom-built according to the specific application context, has been published in this area. This work provides a systematic treatment of how to construct biometric cryptosystems based on iris biometrics. A cryptograp...
متن کاملInformation Leakage of Continuous-Source Zero Secrecy Leakage Helper Data Schemes
A Helper Data Scheme is a cryptographic primitive that extracts a high-entropy noise-free string from noisy data. Helper Data Schemes are used for privacy-preserving databases and for Physical Unclonable Functions. We refine the theory of Helper Data schemes with Zero Secrecy Leakage (ZSL), i.e. the mutual information between the helper data and the extracted secret is zero. We prove that ZSL n...
