Enhanced Biometrics-Based Remote User Authentication Scheme Using Smart Cards
In 2010, Li and Hwang proposed an efficient biometrics-based remote user authentication scheme using smart card. Recently, for improving its security and supporting session key agreement, Li et al. proposed an improvement. The biometrics authentication system offers several advantages over other security methods. Passwords might be divulged or forgotten, and smart cards might be shared, lost, or stolen. In contrast, personal biometrics, such as fingerprints or iris scans, have no such drawbacks. It is ideally suited for both high security and remote authentication applications due to the nonreturnable nature and user convenience.
