Systems, methods, and storage media for obfuscating a computer program by representing the control flow of the computer program as data that is not source code are disclosed. Exemplary implementations may: receive source code of a computer program; parse the source code; extract the control flow of the source code; represent at least a portion of the control flow as a control flow model using a mathematical modeling language; store the control flow model as control flow data that represents the control flow of the program and is not executable code; and remove the at least a portion of the control flow from the source code, to thereby obfuscate the control flow of the source code and render the source code more resistant to tampering.

Systems, methods, and storage media for obfuscating a computer program by representing the control flow of the computer program as data

Systems, methods, and storage media implemented by a computer for enabling tracking of software are disclosed. Exemplary implementations may: receive marking input code corresponding to a computer program; identify locations of the marking input code that can be modified in ways that preserve functionality of the computer program; choose at least one code transformation with associated intrinsic constants; derive derived constants from the specific intrinsic constants; apply the at least one chosen code transformation, including injecting the derived constants into the marking input code; saving the results of the above steps on computer readable media as marked code; and save metadata including a list of the derived constants on computer readable media in a file that is separate from the marked code.

System and method for watermarking software

A method comprising: carrying out optimization of an item of software in a first intermediate representation; carrying out protection of the item of software in a second intermediate representation different to the first intermediate representation.

Optimizing and protecting software

A system and method for producing a massive number of diverse program instances so as to deter differential attacks, collusion, and similar hostile actions. Code portions are shown to be defined in various manners, instantiated, and aggregated. The system and method establishes a very large number of program instances that may be deployed. Furthermore, testing is accomplished over a minimal set of instances to provide for high test coverage and high confidence over the fully deployed in stance set without incurring a high penalty.
