Hi, We run an education startup in bangalore. We are looking for a solution to protect our PDF content from copying, sharing, editing and emailing. We would also like to have full control of our users accessing the document and set expiry date for PDFs. We have a budget go 25 -30K for this solution.
1) User creates a login on website
2) User is authorised and downloads PDF documents from site
3) PDF should expire within a given time frame
