A method for controlling execution of a software application a) determining the point in time of at least one installation of an operation system, installation of a computer program, updating of the operation system, updating of the computer program, b) generating platform information based on the installed/updated system/program and the determined point in time, c) generating a first fingerprint based on the platform information, which is characteristic for the execution platform at the determined time, d) generating a license including said first fingerprint, which defines terms of allowed execution of the software application, and e) controlling the execution by&#x2014;determining platform information used for generating the first fingerprint and generating a second fingerprint based on said platform information&#x2014;comparing the second fingerprint with the first fingerprint, and&#x2014;allowing execution of the software application if the second fingerprint complies with the first fingerprint.

Method and control system for controlling an execution of a software application on an execution platform

A method for controlling an execution of a software application on an execution platform in a first local network comprises: determining a first environment fingerprint including a first network fingerprint characteristic for the first local network using predetermined rules; generating a license including the first environment fingerprint and defining terms of allowed execution of the software application; and controlling the execution by: determining a second environment fingerprint including a second network fingerprint of a local network in which an execution platform for the software application is included using the predetermined rules; comparing the second environment fingerprint with the first environment fingerprint of the license; allowing execution of the software application according to the terms of the license where the second environment fingerprint complies with the first environment fingerprint, and preventing the execution of the software application where the second environment fingerprint does not comply with the first environment fingerprint.

Controlling execution of a software application on an execution platform in a local network

A method of adding a copy protection function to a program to be installed on a computer system comprising a copy protection unit is provided, said method comprising the steps of determining a decision section of the program, wherein information influencing the further course of the program is defined during execution of the program, as a function of the current running state of the program, and converting the decision section by means of code which is executable exclusively in the copy protection unit and which is executed in the copy protection unit during execution of the program.
