<p>The method involves delivering output data (31) based on input data (20) during executing of critical portions, and delivering another output data (32) based on the input data during executing a checking program. The output data are compared, and anomaly information (33) is generated when the output data are different. The anomaly information is transmitted to a remote server, and a primary computer program (11) is continued based on the output data when one of the critical portions of the program is activated. Independent claims are also included for the following: (1) a device for securing utilization of a primary computer program driving a data receiving and delivery device (2) a method for updating a computer program driving a data receiving and delivery device (3) a server for updating a computer program driving a data receiving and delivery device.</p> |
