Abstract (en)

[origin: WO2006085029A2] The invention relates to a method for protection of a file containing a number of descriptions of rights D<SUB>i</SUB> (i=l ... N), each right D<SUB>i</SUB> defining the use by a terminal of at least one resource and/or a digital content from a number of resources and/or digital content RC<SUB>j</SUB> (j=l ... M), each description of a given right D<SUB>i</SUB> comprising in particular, an identifier of said right D<SUB>i</SUB>, an identifier for each resource and/or content RC<SUB>j</SUB> the use of which is defined by the right D<SUB>i</SUB>, and the conditions of use of the resources and/or said content by the terminal. The method comprises the following steps: on receipt of the file of descriptions of rights D<SUB>i</SUB> by a terminal, memorizing said descriptions in the terminal and generating, for each resource and/or content RC<SUB>j</SUB>, a data structure (Id_ RC<SUB>j</SUB>, Id_D<SUB>i</SUB>) comprising the identifier of said resource and/or said content and the identifier of each right D<SUB>i</SUB> defining a use of said resource and/or said content RC<SUB>j</SUB>, and transferring each generated structure (Id_RC<SUB>j</SUB>, Id_D<SUB>i</SUB>) to a secure memory zone.
