Authors and publishers normally encrypt PDF documents to ensure that their contents remain secret to anyone who is unauthorized to view or use them. This file security method uses a secret key to scramble files’ contents. Some PDF security systems avoid password-based encryption (as these are easily cracked) and use public key technology instead so that keys are only made available to the application and not the users. This provides better PDF documents security since there are no passwords for users to share with others and decryption keys are normally held encrypted in a keystore.
We can encrypt PDF files and further incorporate DRM controls so as to regulate what authorized users can do with our protected documents after decrypting them. This enhanced file security enables us to control document viewing, disable printing, modification, copying, sharing, saving and screenshots, and to disable printing to file, image printers or PDF format. We can also decide on the document’s preferred number of views and prints, document expiry dates, as well as document revocation and retention. Indeed this is a complete solution that publishers and authors need in order to protect their PDF format creative works.
