Source code plagiarism detection tool that checks against online content I asked this question on Stackoverflow and was directed to ask it here. The question is:

I wanted to ask about plagiarism detection tools for source code written in C++. When I searched Google the ones I found compare between documents that you already have. What I'm looking for is a tool that compares against content on the internet (i.e Github).
We use the MOSS (Measure of Software Similarity) system provided by Stanford, at here.
