Over the years I’ve run into expert witnesses and attorneys who have told me about software copyright infringement cases where the only clues that copying occurred were patterns of spaces and tabs (“whitespace”). We set out to rigorously test this method.

SAFE Corporation is looking for partners in academia and industry to create a database of purposely plagiarized code to be known as the Depository of Universal Plagiarism Examples or DUPE. Plagiarism detection programs would be run on DUPE to determine which programs best detected copying. Statistics about plagiarized code would be gathered in order to improve the plagiarism detection programs.

There were a number of large lawsuits involving software IP in 2009. We know that CodeSuite was used in many of them (because of protective orders, we don’t know all the cases where CodeSuite was used).

If you have a research idea relating to code analysis, and you can use the SAFE tools, let us know. If your proposal passes our review process you’ll get free licenses to our tools, free support, and help getting your results published.

You have the source code from two different programs. You run them through CodeMatch and find high correlation numbers. Have you proven copying? Not yet. There are still a few steps to go through first.

SAFE has just released a new tool for comparing computer code to detect copyright infringement and trade secret theft. CodeCross™ finds traces of nonfunctional source code that have been copied from one program to another.
According to Nikolaus Baer at Zeidman Consulting, a SAFE Corporation customer, “I suggested the concept of CodeCross after working on cases [...]
