Biometrics Based Remote User Authentication Scheme Using Smart Cards

What is it about?

Remote user authentication is an essential tool for granting access control. This study shows that how the cryptographic key can replace the password in remote user authentication by conceal it with a biometric template and discarded in the registration phase. During the login phase the key is generated using a query biometric template. The strength of the proposed scheme is that it provides resistance to tampering and theft by way of a stored biometric template, privileged insider, and a smart card attacks.

Why is it important?

The remote user authentication schemes rely on passwords or biometric or both, which fall apart if the password is not kept secret. Additionally, the passwords can be stolen, lost, or forgotten and the stored biometric template is highly susceptible to a number of security and privacy attacks. Three significant findings in this paper are 1) provides resistance to tampering and theft by way of a stored biometric template. 2) the scheme works without password (human-memorized) 3) provides renewable property for the protected biometric template.
