“…Approaches for generating cryptographic key from biometrics have considered various biometric traits, such as fingerprint [12][13][14][15][16][17] finger vein [18], iris [19], face [20,21], voice [22], handwritten signature [23], gait [24][25][26][27], ECG [28,29], retina [30] and multi-modal [31][32][33].…”

“…Here, several existing approaches of stable binary string generations are briefly discussed. The generated stable binary string can be used directly as a cryptographic key for symmetric encipherment [12][13][14][15] or it can be used as a seed value to generate the private-public key pairs for asymmetric encipherment [34,35].…”

“…As a result, more mismatch bits need to be corrected using error correction code. Contrary to this binary encoding, gray code-based encoding is presented in [13]. The use of gray code significantly reduces the number of mismatching bits between the key strings generated from two different instances of the same fingerprint.…”

“…Hence, compromise of any one factor (either fingerprint or password) will not lead to the compromise of the generated key pair. Usage of two factors distinguishes the proposed work from all other existing works (including work in [13]). Moreover, similar to the work in [13], the current work also adopts a gray code encoding of decimal values to generate a key bit string from a fingerprint image.…”

“…In a biometric cryptosystem, biometrics is used either to access the cryptographic key (key release) [5,6], to retrieve the cryptographic key without explicitly storing it (key binding) [7][8][9][10][11] or to generate a cryptographic key directly from the biometric features (key generation) [12,13]. Secure transmission/storage and authentication are performed based on the key, which is either accessed, retrieved, or generated using the biometric template.…”

In an asymmetric-key cryptosystem, the secure storage of private keys is a challenging task. This paper proposes a novel approach for generating the same public and private key pair on a need basis. Hence, the need for secure storage of the private key is done away with. The proposed approach for generating the key pair is based on two factors: fingerprint biometrics and password. A stable binary string is generated from the distances among pairs of minutiae points in a fingerprint using a gray code-based method. Experiments show that gray code representation significantly reduces the number of inconsistencies between the generated bit strings from two instances of the same fingerprint as against the binary code representation. Hence, the Reed–Solomon error correction code successfully corrects errors due to variations in multiple instances of the same fingerprint to induce stability in the generated string. Hash of the stable string generated from the fingerprint and the string generated from hashed password are XORed to derive a stable seed value. The proposed approach uses this seed value to generate two large prime numbers. These prime numbers are used to generate the public and private key pair using the RSA key generation method. This seed value ensures the generation of the same key pair every time. The experimental results show that the proposed approach can ensure a stable generation of the key. It is not required to store either the fingerprint template or the password. Moreover, the generated private key is also not stored. It can be regenerated on a need basis.
