I need to make an efficient approach based
on biometrics (Iris or fingerprint) for generation of
secure cryptographic key. The proposed approach is composed of
three modules namely, 1) Feature extraction, 2) Multimodal
biometric template generation and 3) Cryptographic key
generation. Initially, the features, minutiae points and texture
properties are extracted from the fingerprint or iris images
respectively. Subsequently, the extracted features are fused
together at the feature level to construct the multi-biometric
template. Finally, a 256-bit secure cryptographic key is generated
from the biometric [login to view URL] I the key is generated I would want to make an scenario of three way check
The steps I wish to have in my checking program are:
1. Measure biometric
2. Claim ID
3. Bio-encrypted key
4. Retrieve key1 from live biometric and bio-encrypted key
5. Retrieve key2 from smartcard biometric and bio-encrypted key
6. Hashed key1, key2
7. Match:Hashed key == Hashed key1== Hashed key2
