The present invention relates to a method of preventing unauthorized use of a computer program installed on a computer system. The method comprises determining a signature structure on the basis of creation times for identifiers of Cyberfiles, e.g. file catalogues. This signature structure is associated with the computer program which is able to recognize the current signature structure within certain predetermined tolerances during the execution, otherwise the execution is interrupted or changed. The invention finds use preferably for protecting computer programs and database information, including multimedia, against copying. |
