Abstract:

When a server authenticates users based on fingerprint over open network, the process of fingerprint matching is usually handled in the encrypted domain with purpose of protecting the privacy and security of both parties. However, an accurate alignment of the template and the query sample is rather difficult in this situation. An alignment-free fingerprint-matching scheme was presented, which extracts two kinds of local features around the minutiae, ridge orientation and minutiae local structure. Both features have the properties of invariant to rotation and translation. Garbled circuits were designed to implement the corresponding matching algorithm, which allow the server to verify the user without leaking the respective data. Experiment shows that the scheme achieves a relatively higher accuracy on FVC2002-DB2 public database.

Key words: garbled circuits, privacy protection, alignment-free, fingerprint matching
