SIGNIFICANCE OF MULTI-MODAL BIOMETRICS IN DIGITAL ECONOMY

Securing information is a prevailing challenge these days. Smart devices are increasingly relying on the internet and wireless networks. The data is stored on remote servers. The main problems are security theft and unauthorised access to a person's private data. Biometric systems provide the best authentication. A variety of biometrics are being used, such as finger sensors and digital signatures. A multimodal biometric system combines more traits and provides maximum accuracy in authenticating the users. The aim of this survey is to delineate the importance of using multimodal biometrics. Getting illegitimate access in unimodal biometric systems is easy, but multimodal biometric systems need more effort to break into the system. A digital biometric system works on the physiological and behavioural characteristics of an individual. It determines identification through automated technology. Many companies are investing large amounts in multimodal biometric systems and they are mostly being used in IoT devices for security purposes. An economy based on digital computing technologies is a digital economy and multimodal biometric systems are enhancing it. Multimodal biometric systems have a competitive advantage over conventional passwords and unimodal biometric systems. The paper will provide information for researchers constructing multimodal biometric systems.
