Zusammenfassung:Control of access to at least one digital content is managed as a function of at least one access criterion. The digital content is transmitted to at least one terminal in the form a data stream. The access criterion is stored in the terminal as a function of an identifier. The terminal receives the data stream in association with a control message indicating the identifier. It then retrieves the stored access criterion as a function of the identifier received in the control message. Finally, it verifies whether the stored access criterion is satisfied in order, where appropriate, to authorize access to the content.
