ABSTRACT:
This invention concerns a system to update encoded data stored in a memory of a data processing device such as a smartcard. In this system, the data is represented by a tree structure in directories and files according to an object representation. According to the invention, the update system comprises a specific referencing object able to reference all or some of the attributes of the encoded data in memory. A microcontroller is then programmed to extract from the referencing object the information required to locate the memory block occupied by this attribute, and update this block, replacing it by the new previously encoded data.
