摘要 |
The solution concerns the access to a number of data files stored in the memory of a data processing device. The device includes a privilege file (P1-P3) associated with a user type (ADM, PUBLIC, USER1, USER2), said privilege file identifying for at least one command (SEL, INS, UPD, SUP) the data files on which said command can be executed. A microcontroller is programmed to create, when a user accesses the data files, a set of flags from the privilege file, each flag being associated with a unique data file, the flag indicating whether or not the command can be executed on the associated file. |
