MULTIMODAL BIOMETRY

A multimodal biometric method is provided for authenticating at least one user, in which at least one user is assigned to one of at least two classes, in which similarity measures are used that are measures of the similarity of biometric data, determined for the user, to reference data for one of the classes, in which a overall statistical statement on the user's membership of the class is present for each of the at least two classes as a function of the similarity measure, in which the overall statistical statement for each of the at least two classes results from the 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 in which the user is assigned to one of at least two classes when a specific assignment criterion is fulfilled.
