Title: Douglas McPherson Little: Innovator in Software Protection
Introduction
Douglas McPherson Little is a notable inventor based in Glasgow, GB. He has made significant contributions to the field of software protection, holding a total of 4 patents. His innovative methods focus on enhancing the security of computer programs against tampering and unauthorized access.
Latest Patents
One of his latest patents is a method of protecting computer program code. This computer-implemented method involves identifying a location of a dynamic repair target code section for an assignment to a program variable, the value of which is known only at runtime. The method modifies the program code at the identified location to assign an immediate value different from the correct runtime value to the program variable. Additionally, it includes inserting a dynamic repair probe code section that executes before the dynamic repair target code, modifying the immediate value to contain the correct runtime value when an attack has not occurred.
Another significant patent is an anti-tamper system employing automated analysis. This system utilizes runtime profiling of software to determine where to inject integrity checks, enabling verification of whether the software has been tampered with. The runtime profiling records information about the application to optimize protection security while minimizing performance penalties.
