You can lock text in Adobe Acrobat by setting a permissions password so that other users cannot make unauthorised changes to a PDF. Acrobat offers several setting options that allow you to determine the type of changes other users can make to a document. You can allow no changes at all; insertions, deletions and page rotations; form filling and digital signatures; comments, form filling and digital signatures; or everything but page extracting. An additional option allows you to enable or disable the ability to copy text, images and other data from the PDF.
