Abstract

A data processing system (CAR), particularly a smart card coupled to a communication device (MOB), communicating with a remote entity (OP). The data processing system has a location for storing a file (F) which can be downloaded from said remote entity, A program (GS) of the data processing system performs the following steps: before performing data correction in the system, a checking step in which said program (GS) checks whether a file (F) has been downloaded, if such a file (F) is present, the program (GS) modifies the application (APP) on the basis of the data stored in the file (F).

Claims

1. A data processing system (CAR), particularly a smart card coupled to a communication device (MOB), communicating with a remote entity (OP), comprising:

A location for storing a file (F) which can be downloaded from said remote entity;

A program (GS) for performing the following steps;

Before performing data correction in the system, a checking step in which said program (GS) checks whether a file (F) has been downloaded,

If such a file (F) is present, the program (GS) modifies the application (APP) on the basis of the data stored in the file (F).

2. A method for updating an application (APP) stored in a memory of a data processing system (CAR), in particular a smart card coupled to a communication device (MOB), said system being able to communicate with a remote entity (OP), comprising:

Before performing data correction, a program (GS) stored inside the data processing system checks whether a file (F) has been downloaded from said entity into said data processing system,

If such a file (F) is present, said program (GS) modifies the application (APP) on the basis of the data stored in said downloaded file (F).

3. The method according to claim 2, wherein when said program (GS) modifies an application (APP) on the basis of the data stored in the file (F), the program (GS) writes the new code or data and deactivates the previous one.

4. The method according to claim 2, wherein said file (F) has a predetermined identifier (ID), and wherein the program (GS) searches for this identifier (ID) for performing a modification of the application (APP).

5. The method according to claim 4, wherein after the program (GS) has found the identifier (ID), it also checks whether the file (F) is activated or deactivated;

if the file is activated, the program (GS) performs the modification;

if the file is deactivated, the program (GS) doesn'"'"'t perform the modification.

6. Computer program (GS) stored in a data processing system (CAR), in particular a smart card coupled to a communication device (CAR), said system (CAR) including a microcontroller comprising code instructions for performing the following steps:

Before performing data correction in said system, it checks whether a file (F) has been downloaded into said system (CAR),

If yes, it modifies the application (APP) on the basis of the data stored in the file (F).

7. A data processing system (CAR) to store digital information, comprising:

a computer program (GS) comprising code instructions for performing the following steps;

before performing data correction in said system, checking whether a file (F) has been downloaded into said system (CAR),

if a file (F) has been downloaded, modifying the application (APP) on the basis of the data stored in the file (F).
