Abstract:
1. A digital process for authentication of a user of a database for access to protected data or a service reserved for a defined circle of users or for the use of data currently entered by the user, comprising routing a voice sample currently enunciated during an access attempt by the user to a voice analysis unit, computing a current voice profile and comparing the current voice profile in a voice profile comparison unit against a previously stored initial voice profile and, in response to a positive comparison result, authenticating the user and enabling access with a first control signal, but in response to a negative comparison result disabling access with a second control signal or triggering the generating of a substitute authentication procedure, and during authentication carrying out a text-dependent verification and a text-independent verification of the voice profile and combining results of both verification processes with one another in an assessment and decision-making step, and generating the first or second control signal as a result of this step.
