Verfahren zur Identitätsprüfung

摘要

The present invention relates to an identity verification procedure as a prerequisite to granting an access and/or use permission, whereby at least one data set based on biometrical signs enabling identification is built using a data entry and processing system. The invention also relates to facilities for implementing said method. In order to fulfil that task, the biometrical features are first captured in the form of reproductible feature data; a first data set is then generated from random data, which data set is stored on a data medium as a control data set; at least part of the feature data is related to at least part of the control data set and converted by a non-reversible computing operation into a second data set; and this second set is used as a criterion fo granting an access and/or use permission and/or as a cryptographical key setting.
