How can I check for cheating in assignments given by Learning management system

I am using SP based learning management system where I ask students to submit assignments via LMS. However I suspect that many people copy and submit almost identical answers. How can check if they copied?

Solution

Many tools in market offer anti-plagiarism checkers. If you are using SharePoint LMS you can choose between three anti-plagiarism systems: Ephorus, Turnitin and Urkund. These have an inbuilt support.
