Abstract (en)
[origin: DE19860803A1] The invention relates to a method for generating a file identifier for a file to be written into the memory of a processor integrated circuit. According to the invention, at least one part (15) of the file identifier (13) is generated by performing an unequivocal mathematical operation on a predetermined quantity of the code characters (16) of the data code contained in the file (12). Said operation generates a code sequence (23) of a predetermined number of characters for said quantity of code characters. Preferably, the file identifier additionally comprises one part (14) which contains information on the content of the file.
