Abstract :
Fingerprint is immutable and unchangeable. Thus, if it is disclosed, owner of fingerprint cannot use his fingerprint any longer. Fuzzy vault is a cryptographic framework that makes secure template storage to bind the template with a uniformly random key. In order to keep fuzzy vault secure, various schemes are studied using special data like password. K.Nandakumar proposed a scheme for hardening a fingerprint minutiae-based fuzzy vault using password. However, that scheme has vulnerabilities against several attacks. In this paper, we analyze vulnerabilities of K.Nandakumar¿s scheme and propose a new scheme which is secure against various attacks to fuzzy vaults.
