🗣️ Overview # This research topic proposes a cross-architecture software birthmarks that targets the real-world executables such as Linux ELF, Windows PE, and macOS Mach-O. The birthmarks are extracted from the intermediate representation of the executables throughGhidra’s p-code.

🗣 Overview # The software birthmarks were proposed for detecting the software theft from a large number of suspected programs. The birthmark is a technique to compare the extracted characteristics as the software birthmarks, and compute similarities between two birthmarks. The conventional birthmarks require a much time by increasing the target programs for comparison. Therefore, it is the bottleneck of the conventional birthmarking technique. In this paper, we propose a method for reducing total processing time by introducing the narrowing phase between conventional extracting and comparison phases. The narrowing phase employs the fast but rough comparison algorithm in order to eliminate unrelated programs.
🗣 Overview # The software birthmark methods are proposed to find the stolen software from the huge number of suspects. The software birthmark methods are classified into two manners, static and dynamic manners. Different from the static birthmarks, dynamic birthmarks require inputs since they base on runtime behaviors. Also, the dynamic birthmark varies depending on the inputs, therefore, it is difficult to extract beforehand. Hence the extraction cost of the dynamic birthmarks is generally high than the static birthmarks. This paper focuses on unit test codes in a project in order to extract the dynamic birthmarks beforehand, and reduce the extraction cost. The experiments evaluated the credibility and resilience performance of the birthmarks. The performance evaluation showed good results, the similarities were greater than 0.8 between most recent two versions of the same products, and were under 0.355 among different projects. In the cost evaluation, the proposed method can reduce the extraction cost of dynamic birthmarks.
🗣 Overview # This research topics shows applications of software birthmarks. In our publications, we try to classify the programs using extracted software birthmarks. Because, we believe that the birthmarks shows the functionalities of the programs.
