We present and evaluate a novel methodology for improving the performance overhead of dynamic data flow tracking (DDFT) frameworks, by combining static and dynamic analysis. Specifically, we separate the program logic from the corresponding tracking logic, and apply optimization techniques that eliminate redundant tracking and minimize interference with the target program. Our results indicate a DDFT speedup by as much as 2.23x.
