The PS Document Protector software suite securely encrypts PDF documents and wraps them into an EXE (executable) file, that allows only authorised users to view the document contents and only on their own computer.
When a valid license is present the document is opened in a built-in secure PDF Viewer application, that doesn't allow printing and even disables Print Screen and other forms of screen capture by constantly monitoring the clipboard for images.
The license is hardware-locked to the customer's computer and allows him to view the protected document only on his own computer, this way effectively protecting the
intellectual rights of the owner and preventing unauthorised distribution of the document. This isn't a simple check, that can be easily cracked, but the collected hardware information is actually a part of the decryption key for the document. This way it is impossible for the user to decrypt and open the document on different computer, than the registered one.
