Identifying a person is a challenging job in our regular life. The conventional methods includes the password, ID cards, etc [1]. But these identities can easily be misused, lost or shared. To overcome the above limitations of the conventional methods, biometric system has been introduced. The biometric system plays an important role in providing high-security applications such as border control, immigration etc. This paper provides the detailed study of various modules, applications, methods and challenges of the multimodal biometric system.
