A method and system for granting one-time access to a pre-paid product are presented. An authorization center generates a numeric code associated with the product and stores the numeric code in a database. The numeric code is distributed in advance based on a product fee. To access the product, the customer initializes a validation process by transmitting from a terminal having a unique address (UA) to a registration center the numeric code along with the unique address (UA); transmitting from the registration center to the authorization center the numeric code and the unique address (UA); validating the numeric code and retrieving a product identifier from the database or calculating the product identifier from the numeric code; and transmitting from the authorization center to the terminal an authorization message (EMM) for granting access to the product. After use, the numeric code is marked as used to prevent re-use.
La présente invention concerne un procédé permettant d'autoriser les clients à accéder à un produit ou à un ensemble de produits. Ce procédé consiste d'abord à fournir au client via un réseau de communication sûr un code unique pour un centre d'enregistrement; à transmettre ensuite ledit code du centre d'enregistrement à un centre d'autorisation; à extraire l'identificateur du produit ou de l'ensemble de produits dudit code, en interrogeant une base de données ou en calculant ledit identificateur; et enfin, à transmettre via le centre d'autorisation un code d'autorisation au terminal d'abonné, ledit code d'autorisation autorisant alors l'accès au produit ou à l'ensemble de produits.
