<p>The invention relates to a device (15) for preventing illegal exportation of a content protected by a global copy protection system to a local copy protection system. According to the invention, each content liable to be exported contains a unique identifier (CUI) and the device (15) comprises a table (CET) for storing unique identifiers of all contents that have already been exported through said device. The invention also relates to a method for recording a content received by such a device. This method comprises the steps consisting, if the copy is to be made for a local copy protection system, in checking whether the unique identifier (CUI) of said content is contained in the table (CET) of said device; and should said checking be positive, in preventing the recording; and should said checking be negative, in recording the content and storing said unique identifier (CUI) in said table.</p> |
