Prevent Duplicate Google Form Submissions

Vote count:

0

I just built a Google Form for a registration system. I want to prevent duplicate submissions in the form but I don't want to use the option of "Only allow one response per person(Requires Login)" mainly because of the reason that it required login to a Google Account and I don't want that. I hope there could be a solution for the same using Google Apps Script but I am not much familiar with it. Hope if someone can help me out.
