A two-party private string matching fuzzy vault scheme
Xhino Mullaymeri, Alexandros Karakasidis · 2021
A Fuzzy Vault is a cryptographic structure where a secret is being locked by a key and can be unlocked only by another key with significant overlap. In this paper, we introduce a two-party privacy-preserving approximate string matching methodology based on a novel Fuzzy Vault scheme, combining the approximation and security properties of Fuzzy Vaults for privacy-preserving record linkage purposes.
