In case if owner password or permission password is applied the PDF file does not prompt a user to enter any password. However, a user cannot print a document. Even a person cannot select and copy the content of a file to use somewhere else. Another feature that PDF supports with a permission password is that the file can be read using a screen reader. A screen reader is used by the visually impaired people. It depends on a user regarding the extent of protection that he wants to apply.
