Abstract
In this paper, we introduce a novel method to secure cryptographic private key binding and retrieving from fingerprint data using BioHash[1][2], Reed-Solomon error code (RSC)[3] and the thresholded secret sharing scheme[4]. Figure 1 illustrates the schematic diagram of the proposed scheme. Firstly, we generate cancelable biometrics features from fingerprint data through BioHashing and encode the resulting hash. From the encoded BioHash, we formulate the process of cryptographic private key, κ binding and retrieving with the following steps:
Key Binding : b c ⊕ κ = γ (1)
Key Retrieval : γ ⊕ b c ′ = κ’ (2)
where γ is called Biokey, b c and b c ’ refer to the encoded BioHash (gallery sample) and decoded BioHash (probe sample) respectively, while ⊕ denotes bitwise XOR operation.
