I teach programming in high school. In the past, when I looked at a program and knew it was plagiarized, I could google the name of the program (e.g. name of a common game) and track down the code, and sometimes I could literally google some lines of the code and find the source. That doesn't work anymore. Lines of code just turn up nothing, and names often result in dozens of youtube tutorials. Please note, I'm not looking for tools to compare two snippets of code. I'm looking for ways to search for code online that matches my student's code that I believe is plagiarized. Most of the plagiarized code I see is in either python or c++.
I would be so grateful if there's someone out there who can help me outsmart my cheaters.
My teachers were using this and it worked pretty good, if that can help. (Although it doesn't detect the source, only tells if there are similarities from what I know)
