a survey on multi-biometric fusion approaches

The goal of biometrics is to reliably and robustly identify people based on their unique personal characteristics, primarily for security and authentication needs, but also to identify and track the users of more intelligent applications. Fingerprints, iris, palm print, face and voices are frequently used modalities, but there are numerous more potential biometrics, such as stride, ear image, retina, DNA, and even behavior. As an automatic way to identify persons depend on just one (single modal biometrics) or a mix of (multi-modal biometrics). A fusion of two or more photos can be utilized to create multimodal biometrics, and the resulting fused image will be more secure. Several levels of fusion techniques are currently accessible, including feature level, decision level, matching score level, etc. In order to identify the human biometric by extracting features and classifying images, this paper discusses different fusion approaches that are implemented in multimodal biometrics. It also describes the datasets that were used and the outcomes ,results and conclusions that were obtained.
