Digital method and device for authenticating a user of a telecommunications / data network

摘要

The method involves routing a voice sample currently enunciated during an access attempt by a user on a telecommunications or voice over Internet Protocol terminal device e.g. mobile phone (3), to a voice analysis unit. A current voice profile is compared with an initial voice profile in a voice profile comparison unit (27). The user is authenticated and a control signal enabling access is generated in response to a positive comparison result. Another control signal disabling access or triggering a substitute authentication procedure is generated in response to a negative comparison result. An independent claim is also included for an arrangement for realization of a method for authenticating a user of a telecommunications or data network 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.
