Protect the format from Changes
I have created a PDF Form and programmed all fields. However, I noticed that if anyone open the file though Acrobat pro, they will be able to modify the format or do some changes in the JavaScript code.
So, is there a way to block the users from changing the content, JavaScript code, or the format of the file while maintaining their ability to fill the form fields ?
Also, if restriction is possible, then will that affect extracting the data later from the PDF file ?
Thanks.
