Methods of identifier determination and of biometric verification, and associated systems

摘要

Abstract The invention relates to a method of determining an identifier of determined discriminating power from biometric data. According to the method, biometric data is obtained relating to an individual (1). The biometric data is converted into a digital string (wi) . A word (ci) of an error-correcting code is associated with the individual. The error-correcting code word is added to the digital string. An identifier (H (ci) ) relating to the individual is determined by applying a hashing function (H) to the error-correcting code word, the hashing function being selected to ensure the determined discriminating power to said identifier. 2597862_2 (GHMate) P75520AU 9.' *% G. c5CD
