Method and apparatus for controlling the access of a user to a service provided in a data network

摘要

Process for controlling the access of a user to a service provided in a data network, to protect user data stored in a data base of the service from unauthorized access, the method comprising: (a) inputting, in a VoIP session, a voice sample of the user at a user data terminal which is at least temporarily connected to the data network, (b) processing, in a first processing step, the user's voice sample using a dedicated client implemented at the user data terminal, to obtain a pre-processed voice sample or a current voice profile of the user, (c) further processing, in a second processing step, the pre-processed voice sample or the current voice profile, including a comparison step of the current voice profile with an initial voice profile stored in a data base, and (d) outputting an access control signal for granting or rejecting access to the service, taking the result of the comparison step into account.

1. Process for controlling the access of a user to a service provided in a data network, to protect user data stored in a data base of the service from unauthorized access, the method comprising:
(a) inputting, in a VoIP session, a voice sample of the user at a user data terminal which is at least temporarily connected to the data network, (b) processing, in a first processing step, the user's voice sample using a dedicated client implemented at the user data terminal, to obtain a pre-processed voice biometric sample or a current voice profile of the user, (c) further processing, in a second processing step, the pre-processed voice biometric sample or the current voice biometric profile, including a comparison step of the current voice biometric profile with an initial voice biometric profile stored in a data base, (d) outputting an access control signal for granting or rejecting access to the service, taking into account a result of the comparison step, and after step (b) the pre-processed voice biometric sample or the voice profile is transmitted to a voice authentication server via the data network, the second processing step (c) is carried out at the authentication server, and the authentication server outputs the access control signal to a server of the service.
