Aspects of the present disclosure relate to enhancing biometric security. A biometric template and a biometric sample can be compared using a first security technique having a first ECC framework with a first number of codewords. A determination can be made that the biometric template and biometric sample do not match using the first security technique. The biometric template and the biometric sample can then be compared using a second security technique having a second ECC framework with a second number of codewords, the second number of codewords less than the first number of codewords. A determination can then be made that the biometric template and the biometric sample match, and a user associated with the biometric sample can be verified.
