Abstract: A method and system for creating uniquely representative execution path identifiers of software program. The method comprises the steps of running the software program, continuously accessing execution information of the software program, identifying execution sequences of the execution information, and creating a unique execution path identifier of each of the execution sequences by summing the execution information when the execution information is within a functional boundary thereof so as to create an execution path identifier representing a unique execution sequence of the execution information. The system comprises an execution path identification creator continuously receiving and accessing execution information of the software program, identifying execution sequences of the execution information and creating the unique execution path identifier of each of the execution sequences.
