Can my below expectations in PDF is possible?
1. While i open the PDF it should compare itself by creating fresh hash of the document and compare the hash in-built in the PDF document and get verified. (Presently only Adobe does within itself, i don't want dependency on Adobe.)

2. While i click a link in the PDF, the PDF should direct to the link (web application)  along with the hash of the fresh document. How can i do?. If i embed .exe it will not accept in all systems.

3. Can a PDF created and shared to get accepted across the world without dependency of Adobe or any other system compatibility.

Request someone to give a solution with detail. Thanks.
