FIELD: physics, computer engineering.
SUBSTANCE: invention relates to computers and their software and dataware, and specifically to methods and means of protecting applications from unauthorised copying and distribution and can primarily be used by software and dataware developers to restrict unauthorised use of program and information products. The aim is achieved by using a method of protecting software and dataware from unauthorised use using applications, involving plotting a control flow graph and complicating transforms, wherein after plotting the graph, the application is interpreted in form of a finite machine and divided, application variables are protected and low-level software is generated for an external apparatus module.
EFFECT: high degree of protecting applications and high efficiency of the protected application.
