A cryptographic biometric authentication system based on genetic fingerprints
(SICHERHEIT 2008 – Sicherheit, Schutz und Zuverlässigkeit. Beiträge der 4. Jahrestagung des Fachbereichs Sicherheit der Gesellschaft für Informatik e.V. (GI), 2008) Korte, Ulrike; Krawczak, Michael; Merkle, Johannes; Plaga, Rainer; Niesing, Matthias; Tiemann, Carsten; Vinck, Han; Martini, Ullrich
We specify a system for authentication and key derivation using genetic fingerprints which prevents the recovery of biometric information from data stored for verification. We present a detailed security analysis based on estimates of the entropy of the DNA data and formal security results. The scheme is shown to be robust and efficient by analysing the typical frequency and structure of errors in DNA measurements and selecting appropriate error correcting codes. As a result we obtain an authentication system that offers a security level equivalent to cryptographic keys with 73 bits and a FRR well below 1%.

Virtual PIN: Biometric encryption using coding theory
(BIOSIG 2003 – Biometrics and electronic signatures, 2003) Martini, Ullrich; Beinlich, Stephan
A new biometric system is proposed which replaces the template match known from presently used biometric systems by a more powerful approach that uses error tolerant coding. This enables the system for new applications and enhances compatibility to non-biometric systems which are in use now.
