    Multimodal biometric systems aim to achieve the best performance in persons recognition, by combining more than one biometric modality so that the combination is done using the fusion principle. In fact, although different levels of fusion are available, score-level fusion is the most commonly used. Indeed, in this process and before combining, the heterogeneous scores provided by the different biometric subsystems must be normalized. In this paper and in order to cancel the scores normalization step, a fuzzy fusion strategy has been proposed. Our experimental results, using a PolyU finger-knuckle-print database, show that the proposed fusion scheme improves the results compared to the Z-score normalization method followed by the min and max classical combining arithmetic rules.
