CA 2341100

In order to restrict data access in a receiver/decoder, a plurality of sets of access rights are assigned to the data, each set of access rights being assigned to at least one party. The data, the sets of access rights and an identifier for each party are stored in a memory of the receiver/decoder. The identifier of a party requesting access to the data is compared with the or each identifier stored in the memory, and the party provided with the set of access rights assigned thereto in the memory of the receiver/decoder.

Afin de limiter l'accès aux données dans un récepteur/décodeur, plusieurs ensembles de droits d'accès sont attribués aux données, chaque ensemble de droits d'accès étant attribué à au moins une partie. Les données, les ensembles de droits d'accès ainsi qu'un identificateur pour chaque partie sont stockés dans une mémoire du récepteur/décodeur. L'identificateur d'une partie demandant l'accès aux données est comparé à l'identificateur ou à chaque identificateur stocké dans la mémoire, et la partie reçoit l'ensemble de droits d'accès qui lui sont attribués dans la mémoire du récepteur/décodeur.
