Protect your Schoolwork

With the advent of online e-learning, more people are students than ever before in history. Students are constantly producing high-quality, original work, alongside large numbers of their peers. How can students work together and collaborate, while still producing original, creative works which aren't similar to the works of others? This is a fundamental concept in security that must be considered. Students have a strong, practical need to keep their work original and un-viewed by others until the time comes for peer review.

With password protect for PDF documents, students can understand intuitively that their work hasn't been edited or seen by anyone else until it's time to turn the work in. Students can share the password-protected work in group file upload locations, on flash drives, or on shared network storage locations. Students can send their documents in emails and messages to their peers, professors, and more. All the while, they can have an added layer of assurance.

Only those people who are intended to view can view, and only those that should edit can edit. What if your precious work is shared with the class? Instead of needing to re-do it, generating again original work, make it password protected. When it's shared, it's still blocked and protected from prying eyes, and only viewable by the people you want.
