Abstract
A first process operating on a computer comprises code to be executed in connection therewith, where the code includes at least one triggering device. A digital license corresponds to the first process and sets forth terms and conditions for operating the first process. A second process operating on the computer proxy-executes code corresponding to each triggering device of the first process on behalf of such first process. The second process includes a selection of options to thwart reverse engineering by a debugger if a debugger is detected. The options include execution by a proxy engine of a re-routed call, crashing the first process, detection ad elimination of a debugger related interrupt a call to an arbitrary function.
