A Comprehensive Analysis on the Leakage of Fuzzy Matchers. (arXiv:2307.13717v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
The present paper presents a comprehensive analysis of potential information
leakage in distance evaluation, with a specific emphasis on threshold-based
obfuscated distance (i.e. Fuzzy Matcher). It includes detailed descriptions of
various situations related to potential information leakage and specific
attention is given to their consequences on security. Generic attacks
corresponding to each scenario are outlined, and their complexities are
assessed. The main contribution of this work lies in providing an upper bound
on the security of a fuzzy matcher in …
