Biometric data processing e.g. recognizing, method for e.g. access control system, involves expressing sets of biometric data in multidimensional repository with dimensions, where data is obtained by processes related to biometric part

摘要

The method involves determining an encoded key by using a disjunction between sets of reference biometric data and biometric data and determining if two sets of biometric data mutually correspond by comparing information concerning two encoded keys. The sets of biometric data are expressed in a multidimensional repository with N dimensions, where the biometric data according to one of the N dimensions is obtained by using processes related to a biometric part. One of the keys is obtained by encoding transforming an initial word of specific length into an encoded word in the repository. Independent claims are also included for the following: (1) a device for processing biometric data related to a biological part in a biometric system (2) a biometric data processing system comprising a biometric data processing device.
