MOSS System for detecting software plagarism
 
  • MOSS is a free service hosted by Stanford University. Faculty submit a set of software source code files turned in by students for a particular programming assignment and the MOSS server produces web pages listing pairs of programs with similar code.
  • MOSS also highlights individual passages in programs that appear the same, making it easy to quickly compare the files.
  • Finally, MOSS can automatically ignore matches on the parts of the assignments that one expects to be shared (e.g., software libraries or instructor-supplied code), thereby eliminating false positives that arise from legitimate sharing.
  • To obtain a Moss account, send a mail message to moss@moss.stanford.edu. The body of the message should appear exactly as follows:
    registeruser
    mail username@domain (your email address)
  • If you already have an account, the latest submission script can be downloaded here and additional information is available here: MOSS.
