Multimodal biometric systems have been widely used to achieve high recognition accuracy. This paper presents a new multimodal biometric system using intelligent technique to authenticate human by fusion of palm and finger veins pattern. We developed an image analysis technique to extract region of interest (ROI) from palm and finger veins image. After extracting ROI we design a sequence of preprocessing steps to improve palm and finger veins images using Homomorphic, Median filter, Wiener filter and Contrast Limited Adaptive Histogram Equalization (CLAHE) to enhance vein image. Our smart technique is based on the following intelligent algorithms, namely; principal component analysis (PCA) algorithm for feature extraction and k-Nearest Neighbors (K-NN) classifier for matching operation. The database chosen was the CASIA Multi-Spectral Palmprint Image Database V1.0 and Shandong University Machine Learning and Applications - Homologous Multi-modal Traits (SDUMLA-HMT) database. The achieved result for the fusion of both biometric traits was Correct Recognition Rate (CRR) is 97.9%.
