According to the recent work done in the area of remote user authentication, biometrics based password authentication using smart card is the most interesting and upcoming technology. Many protocols has been designed aiming to combine three authentication factors efficiently in order secure the process of remote user authentication, but failed to do so. One of the many possible reasons is biometrics comparison. Basically, biometric is used to uniquely identify the user. It has been observed that, the biometrics comparison during the verification is done using its hash value, which is infeasible due to its avalanch effect property.
