Claim One:
1. A method comprising: extracting a set of enrollment feature points from an enrollment biometric measurement; randomly selecting one or more enrollment code words from an error correction code; determining obfuscated enrollment feature point data describing an obfuscated version of the set of feature points that is obfuscated using the one or more enrollment code words so that the set of feature points cannot be determined from the obfuscated enrollment feature point data without the one or more enrollment code words; determining obfuscated enrollment code word data describing an obfuscated version of the one or more enrollment code words that is obfuscated using a random enrollment polynomial so that the one or more code words cannot be determined from the obfuscated enrollment code word data without the random enrollment polynomial; determining an enrollment biometric template including the obfuscated enrollment feature point data and the obfuscated enrollment code word data; and determining, using a processor-based computing device programmed to do the determining, enrollment data that keeps the one or more enrollment code words and the random enrollment polynomial secret, the enrollment data including the enrollment biometric template.
