Securing Revocable Iris and Retinal Templates using Combined User and Soft Biometric based Password Hardened Multimodal Fuzzy Vault
Biometric systems are subjected to a variety of attacks. Stored
biometric template attack is very severe compared to all other
attacks. Providing security to biometric templates is an important
issue in building a reliable personal identification system. Multi
biometric systems are more resistive towards spoof attacks
compared to unibiometric counterpart. Soft biometric are
ancillary information about a person. This work provides
security and revocability to iris and retinal templates using
combined user and soft biometric based password hardened
multimodal biometric fuzzy vault. Password hardening provides
security and revocability to biometric templates. Eye biometrics
namely iris and retina have certain merits compared to
fingerprint. Iris and retina capturing cameras can be mounted on
a single device to improve user convenience. Security of the
vault is measured in terms of min-entropy.
