Abstract
The invention refers to a procedure for storing data objects,in the memory,of a smart card,To do this, general and application-specific data objects are defined using freely selectable security characteristics and access rights, which are filed in the memory of a smart card which is divided into several application-specific memory areas,so that data objects with identical access conditions are located in one and the same memory area, irrespective of the application program,or smart card user,to which these data objects are allocated. All application programs and the smart card user can access the data objects irrespective of the corresponding access conditions. In this way, the re-issuing of smart cards in the case of later expansion of the file structure of the smart card for an application or the addition of extra applications is not necessary. The smart card user can allow any applications to store data on his smart card.
