Asking user for permission

Hello,
I started Java today and I am trying to make applet that makes it possible to upload image directly from clipboard. But well, I am sure by default, java can not mess up with users clipboard and steal data from it. So how do I ask user from his permission to get image and work with it? Will it be necessary to ask every time?
Thank you for any help.

I've not done this personally, but this link seems relevant.

Sign the applet. See What Applets Can and Cannot Do (The Java™ Tutorials > Deployment > Java Applets) and https://forums.oracle.com/forums/thr...readID=1534616
