| Abstract: | There are many forms of plagiarism which are indistinguishable from genuine work which causes problems for university-level institutions as students who get away with plagiarism are likely to do it again even after finishing their education. Genuine and plagiarized work is often differentiated from each other by comparing the work with work previously submitted, which is the method used by the primary plagiarism detection program used by universities known as Turnitin. This method of detecting plagiarism however cannot detect contract work, which is work done by a different person for some sort of compensation. In cases of contract work, the original is never published and thus not available for comparison. Other methods of detecting plagiarism however do exist, namely invisible watermarking. Invisible watermarking is a text-steganographic technique where invisible markers are added throughout a document so that the work can be traced back to its source. This research expands onto this idea by developing a novel tool that adds invisible watermarks to Overleaf project files whilst they are being created. These watermarks will include a student id and a timestamp so identification is possible. These watermarks become invisible by encoding them into zero-width UTF-8 characters, and they are encrypted using AES-CBC so tampering becomes more difficult. The research shows that invisible watermarking using zero-width characters is a promising avenue for the detection of plagiarism in the case of contract cheating. |
