Abstract
A method for authenticating biometric data. Comprising of a processor that measures the reliability of each bit in enrollment biometric data; by arranging the bits; encoding the enrollment biometric data in the decreasing order to produce an enrollment syndrome; arranging the bits in the authentication biometric; decoding the authentication enrollment syndrome to produce an estimate of the enrollment biometric data; generating an output signal indicating that the estimate of the authentication biometric data is substantially the same as the enrollment biometric data.
Claims15
A method for authenticating biometric data, comprising a processor for performing steps of the method, comprising the steps of:
- measuring a reliability of each bit in enrollment biometric data;
- arranging the bits in the enrollment biometric data in a decreasing order of the reliability of each bit;
- encoding the enrollment biometric data in the decreasing order to produce an enrollment syndrome;
- arranging the bits in the authentication biometric data in the decreasing order of the reliability of each bit;
- decoding the authentication enrollment syndrome in the decreasing order using the enrollment syndrome and a syndrome decoder and to produce an estimate of the enrollment biometric data;
- generating an output signal indicating that the estimate of the authentication biometric data is substantially the same as the enrollment biometric data.
The method wherein the encoding and decoding uses a low-density parity check (LDPC) code.
