Turnitin is a plagiarism detection service. The Turnitin software checks for potentially unoriginal content by comparing submitted work to several databases using a proprietary algorithm. It scans its databases and has licensing agreements with large academic proprietary databases.
All work submitted by our students is stored in a database to check for plagiarism. This action prevents one student from using another student's work by identifying matching text between papers. In addition to student work, the database contains a copy of the publicly accessible Internet, with the company using a web crawler to add content to Turnitin’s archive. It also contains commercial and/or copyrighted pages from books, newspapers, and journals.
