Abstract
A computer-implemented method and system for binding digital rights management executable code to a software application are disclosed. The method and system include selecting a memory page of host application code, translating the contents of the selected memory page of host application code, saving the translated contents of the selected memory page into a stub code area, overwriting the selected memory page of host application code; removing host page permission for execution of code in the selected memory page of host application code, and emulating the translated contents of the selected memory page when an exception is raised as a result of attempted access to the selected memory page of host application code.
