Novel methods for Multimodal Biometric System to Strengthen the Security

The internet is becoming a more important part of everyone's life in this technological age since it serves a variety of everyday requirements such as social networking, banking, communication, information sharing, etc. In many situations, an increase in need raises the possibility of stealing. As a result, it is necessary to protect the system from theft and provide a layer of protection so that anybody may profit from advanced technology without fear. Passwords are used in traditional security systems for authentication, and they are easy to crack. The idea of biometrics in the realm of security was introduced. Unimodal Biometrics Systems were first introduced in the field of security. Various traits such as fingerprints, face, iris, voice, finger veins, signature, and others were widely accepted by various systems. However, as technology advances, the threat level rises, and the scope of unimodal systems shrinks. This is the primary reason for the growing popularity of multimodal biometric systems, in which more than one modality is employed, and a security lock is established. The level of security is increased with these multimodal systems. The features of the multimodal biometric system, its relevance, current systems are covered in this article, along with the analysis based on traits and its performance.
