Nowadays all engineering students must possess coding skills in several programming languages. Regrettably, students do not perceive the importance of such skills often. Instead, they look for risky shortcuts to accomplish projects or homework in programming courses by copying the code from their colleagues or internet sources. Therefore, in programming languages courses it is necessary to identify this kind of activity well known as plagiarism. The idea behind plagiarism detection is to correct this attitude, raise the morale of the course and show the importance of programming for the training of the future engineer. In the present effort, we develop an automatic, fast and efficient methodology to detect code plagiarism without the professor intervention or code comparison. The results seem promising since the applied mythology detected plagiarism that was confirmed by students afterwards.
