Person identification and authentication is the biggest challenge in our society. Identity may be considered as a public information, but an authentication must necessarily be private-a secret that is known only to the user. Moreover, the authentication must be a conscious process that requires active participation by a user, but not necessarily an identity verification (Agrawal et al., 2017) . User ID (Login ID), cryptographic public keys, email ids, ATM or smart cards; some common authentication credentials are passwords (including OTPs), PINs, and cryptographic private keys. Now Government of India have launched a World's largest database based a digital project known as "Aadhaar". It provides a 12 digit unique code to each person which shows the uniqueness of a person in the world. Aadhar is the best example of multimodal biometric system which contains the demographic information with multiple biometric traits such as face, iris, fingers, and thumbs. Most of the government services and resources are linked to Aadhaar number of a person for authenticity and security.
