ABSTRACT
Securing data storage using
biometrics is the current trend. Different physiological as well as behavioral
biometrics like face, fingerprint, iris, Gait, voice etc.. is used in providing
security to the data. The proposed work explains about the biometric encryption
technology which will securely generate a digital key using two biometric
modalities. Iris is encrypted using Fingerprint ID of 32-bit as the key in this
work. For encryption Blowfish algorithm is used and the encrypted template is
stored in the database and one is given to the user. During the authentication
time user input the template and the fingerprint. This template is then
decrypted and verified with the original template taken from the database to
check whether the user is genuine or an imposter. Hamming distance is used to
measure the matching of the templates. CASIA Iris database is used for
experimentation and fingerprint images read through the R303 - fingerprint
reader.
