plagiarism-detection

I want to develop a plagiarism checker for checking several source codes but I couldn't find any proper source code or even a resource to get an idea about it. I have checked the Boss2 which is useless. they claim that they use Sherlock module for detecting plagiarism but it seems there is no such tools included in boss2. if any open source detection tool is available for checking source code please let me know. regards I'm aware of open-source plagiarism detectors for text (e.g., WCopyFind ), but not code. I couldn't find... even a resource to get an idea about it. The authors of the

I have a couple of simple C++ homeworks and I know the students shared code. These are smart students and they know how to cheat moss. I'm looking for a tool that can rename variables based on their types (first variable of type int will be int1, first int array will be intptr1...), or does something similar that I cannot think of now. Do you know a quick way to do this? edit: I'm required to use moss and report 90% match Thanks Yep, the tool you're looking for is called a compiler. :) Seriously, if the programs submitted are exactly the same except for the identifier names, compiling then (

I'm search for a tool that could compare source codes for similarity. We have a very trivial system right now that has huge amount of false positives and the real positives can easily get buried in them. My requirements are: reasonably small amount of false positives good detection rate (yeah these are going against each other) ideally with a more complex output than just a single value usable for C (C99) and C++ (C++03 and optimally C++11) still maintained usable for comparing two source files against each other usable in non-interactive mode EDIT: To avoid confusion, the following two code
