Abstract:     Apparatus for preventing unauthorized use of a voice dialing system and, particularly, a call forwarding feature associated with the system whereby system users may forward a telephone number respectively associated therewith to a remote location in order to receive phone calls at the remote location, comprises: a database for pre-storing telephone numbers of system users and for pre-storing acoustic models respectively representative of speech associated with each system user, the acoustic models respectively corresponding to the telephone numbers; and a speaker identification module operatively coupled to the database for obtaining and decoding a speech sample from a potential system user during the potential users' attempt to make a telephone call, the speaker identification module comparing the decoded speech sample obtained with the pre-stored acoustic model associated with the telephone number dialed by the potential user; whereby if the decoded speech sample substantially matches the pre-stored acoustic model, then the phone call attempted by the potential user is terminated.

Show all 13 claims
What is claimed is:     1. A method for preventing unauthorized use of a service in a system providing a plurality of services, the method comprising the steps of:
  • (a) pre-storing a biometric model for each enrolled user of the system;
  • (b) associating the biometric model of an enrolled user with a system service, if the enrolled user is not authorized to access the system service;
  • (c) obtaining biometric data from an enrolled user requesting access to a system service; and
  • (d) performing biometric identification by comparing the obtained biometric data with each biometric model associated with the requested system service;
  • wherein if the obtained biometric data substantially matches one of the biometric models associated with the requested system service, the enrolled user is denied access to the requested system service.
