Digital tools cannot stop plagiarism before it happens. The good news is that certain tools can tap the power of automated search and the depth of digital content databases to make the same standard process faster and more thorough. SearchInform Technologies Inc's PlagiatInform allows professors to cross-check student papers against the university's submission database and returns an estimate of what percent of the work has been lifted from another source. Another option is Turnitin, iParadigms' anti-plagiarism tool and digital assessment suite, used by over 7,500 schools so far. It operates either as a standalone application or as an integrated part of the school's content management and communications systems. The corporate counterpart to iParadigms' Turnitin plagiarism-detection tool is iThenticate. The Web-based application scans an extensive page cache and content database and, if any pattern matches are detected, the content is flagged and shown alongside the source.
