I found that if I go into form properties>PDF Security and set up as
shown in the screen shot below the user can fill, sign, save and print
in Reader DC and Acrobat DC but it can not opened in Livecycle to edit
or steal my work without my password. It is my understanding though that
there is third party software out there that can get around it. I wish
Adobe would come up with a security system that is harder to hack.
