Abstract:
1. A multimodal biometric method, comprising the steps of: assigning at least one user to one of at least two classes, the assignment criterion being selected so as to produce a desired assignment rate of users to one of the at least two classes; using similarity measures of biometric data, determined for the user, to reference data for the respective class; presenting an overall statistical statement on the user's membership of the class for each of the at least two classes as a function of the similarity measures, wherein the overall statistical statement for each of the at least two classes results from a combination of the statistical statements of at least two individual biometries for the respective class, the statistical statements of the individual biometries being statistical statements on the user's membership of the class as a function of the similarity measures; and assigning the user to one of the at least two classes when an assignment criterion is fulfilled that depends on the overall statistical statements, wherein the assignment criterion is fulfilled when a ratio of the overall statistical statement on the user's membership of the one of the at least two classes to the overall statistical statement on the user's membership of the other of the at least two classes exceeds a prescribed value.
