    Abstract: The present invention is a method of biometric authentication. The first step is taking a series of measurements of the biometric. The second step is averaging those measurements to create a valid iris model. The third step is generating a random number. The fourth step is using an error-correcting code to create a codeword using the random number. The fifth step is generating a list of random locations corresponding to valid bits in the biometric reading. The sixth step is generating a list of numbers consisting of the combination of specified biometric bits and the codeword. The seventh step is generating the secret by performing a hash on the random number. The eighth step is storing the secret and the list to a certificate. The ninth step of the method is authenticating the subject.
