Abstract	While the advent of open source code search tools have made the source code of thousands of open source software (OSS) readily accessible, thereby increasing legitimate reuse, it has also opened up the possibility of unconscientious employees plagiarizing code from OSS repositories. Plagiarism in proprietary software would not only lead to costly lawsuits, but also undermine the credibility of the organization. Hence detecting plagiarism in proprietary software is an urgent need. Though there exist a number of techniques for detecting plagiarism in student project assignments, they do not scale well in the case of large proprietary software. Especially when code snippets are plagiarized from the large number of available open source software. In this paper we propose a novel approach that applies Mining Software Repositories (MSR) based techniques to the problem of plagiarism detection. We create a programming style profile for each maintenance engineer by mining the version history and use that to detect source code commits that are likely to be plagiarized. Such suspected code fragments can be analyzed using any of the existing plagiarism detection techniques to confirm the plagiarism and ascertain the original code.
