Software plagiarism has become a serious threat to the health of software industry. A software birthmark indicates unique characteristics of a program that can be used to analyze the similarity between two programs and provide proof of plagiarism. In this paper, we propose a novel birthmark, Authority Histograms (AH), which can satisfy three essential requirements for good birthmarks - resiliency, credibility, and scalability. Existing birthmarks fail to satisfy all of them simultaneously. AH reflects not only the frequency of APIs, but also their call orders, whereas previous birthmarks rarely consider them together. This property provides more accurate plagiarism detection, making our birthmark more resilient and credible than previously proposed birthmarks. By random walk with restart when generating AH, we make our proposal fully applicable to even large programs. Extensive experiments with a set of Windows applications verify that both the credibility and resiliency of AH exceed those of existing birthmarks; therefore AH provides improved accuracy in detecting plagiarism. Moreover, the construction and comparison phases of AH are established within a reasonable time.
