An Internet service designed to find cheating students has been launched in
the US. It will compare essays against a database of previously submitted
papers. 鈥淚f you know there is the potential to get caught, you鈥檙e not as likely
to plagiarise,鈥� says Warren Brantner, president of Integriguard of Harrisburg,
Pennsylvania. Tutors sign up for about $5 a month and get their students
to e-mail their essays to Integriguard. Brantner鈥檚 database contains 600 essays
from a company that sells ready-written essays to students. New essays will be
added over time.
