Multi-modal biometrics enjoy more merits than their single-modal counterparts in terms of accuracy performance and security. The fusion of hand-based biometrics such as palmprint and palmvein is straightforward since they can be acquired simultaneously with a customized image acquisition device. Conjugate 2DPalmHash Code (CTDPHC), which is constructed by 2DPalmHash Codes (2DPHCs) of palmprint and...
