<p>The invention concerns a method for authentication of clients who are entitled to receive a service. The method comprises the following steps: A client is contacted through a telecommunications network by a service provider. Information is exchanged through the telecommunications network, concerning the service to be provided. The parties agree in the providing of a service through the telecommunications network. Thereafter, a service identifying code is sent to the client as a confirmation of the ordered service. The service identifying code also serves to identify the contents of the service to be provided. The service identifying code is generated using a unique client identifying code associated to the telecommunication means used by the client for establishing contact through the telecommunications network. Such a client identifying code is used, which is automatically forwarded to the service provider in the course of the normal use of the telecommunications network. The service identifying code is generated so that a service identifying code is associated to one and only one client identifying code. Finally, the service is provided to the client who possesses the service identifying code. The invention also concerns the system and computer program product implementing the method.</p> |
