| In general, identification and verification are done by passwords, pin number, etc., which are easily cracked by others. To overcome this issue, biometrics has been introduced as a unique tool to authenticate an individual person. Biometric is a quantity which consists of individual physical characteristics that provide more authentication and security than the password, pin number, etc. Nevertheless, unimodal biometric suffers from noise, intra class variations, spoof attacks, non-universality and some other attacks. In order to avoid these attacks, the multimodal biometrics, i.e. a combination of more modalities is adapted. Hence this paper has focused on the integration of fingerprint and Finger Knuckle Print (FKP) with feature level fusion. The features of Fingerprint and (FKP) are extracted. The feature values of fingerprint using Discrete Wavelet Transform and the key points of FKP are clustered using K-Means clustering algorithm and their values are fused. The fused values of K-Means clustering algorithm is stored in a database which is compared with the query fingerprint and FKP K-Means centroid fused values to prove the recognition and authentication. The comparison is based on the XOR operation. Hence this paper provides a multimodal biometric recognition method to provide authentication with feature level fusion. Results are performed on the PolyU FKP database and FVC 2004 fingerprint database to check the Genuine Acceptance Rate (GAR) of the proposed multimodal biometric recognition method. The proposed multimodal biometric system provides authentication and security using K-Means clustering algorithm with GAR=99.4%, FRR=0.6% and FAR=0% with security of 128 bits for each modality. | ||
