Embodiment Construction

[0007] The invention is based on the discovery that authentication can be made more reliably in general if the authentication process takes into account parameters unique to each person, which parameters are determined with reference to the individual characteristic qualities of this person. For a biometric feature "fingerprint", for example, the moisture of the skin is the figure of merit. If the skin of the person concerned is comparatively neither too dry nor too wet, the parameter for the characteristic quality of this individual is set to exceed 100% of the standard value, whereas in the case of very wet or very dry skin, This parameter is set at 100% below the standard value.

[0008] This increased or decreased individual parameter as an absolute deviation from the standard value can then be taken as a measure for lowering the individual threshold over the standard threshold. The standard threshold can be determined to be relatively high, such as 80%, instead of the ab...

Abstract

A method, apparatus and system for biometric authentication of a person are proposed. Since the detection of biometric data never matches 100 percent, authentication is already effected when the detected data exceed a defined threshold value in comparison to stored reference data. In order to increase security, the invention provides that information about the person's individual properties influencing the biometric data is stored and taken into account in the authentication process. For example, the threshold value is set low upon comparison of a fingerprint only if the person has exceptionally dry or moist skin. On the other hand, the sensor for detecting the biometric data of the fingerprint can also be set to be more sensitive or less sensitive depending on the stored information.

Description

technical field [0001] The present invention generally relates to a method of authenticating a person by detecting an individual biometric characteristic of the person and comparing the characteristic with corresponding previously stored biometric characteristics of the person. In particular, the present invention relates to a method for biometric authentication of a person, an apparatus (e.g. a data carrier such as a smart card, etc.) device system. Background technique [0002] For biometric verification, a person's biometric feature, such as a fingerprint, is checked by detecting the biometric feature and comparing it with a previously stored biometric feature for sufficient similarity. A successful comparison grants the person access to data, room entry, and the like to prevent unauthorized access. The biometric features stored as reference data can be stored in any instrument, such as a fingerprint door opener, or can be carried around by being...
