The biometric data are stored in the template in which various techniques are used to protect it against privacy and security threats. The binary vector derived from biometric samples provides a great portion of template protection technique. For the same template protection system it is observed that there is a large variation on its key length. It determines the analytical relationship between the classification performance of the fuzzy commitment scheme and theoretical maximum key size given as input on Gaussian biometric source. The number of enrolment, verification sample, features component and biometric source capacity.
