How to Prevent eBook PDF Piracy and Unauthorized Sharing

There is always a piracy concern attached to the sharing of PDF files of eBooks. What if my eBook PDF gets pirated? How can I ensure the authenticity of my eBook? What if someone copies or edits my eBook? How can I ensure authorized viewing of my eBook? It's very common to have such questions in your mind whenever you create a PDF version of your eBook.

While there are multiple options to prevent eBook piracy like watermarking, password protection, digital rights management, setting up Google alerts and so on, these ways of preventing eBook piracy can be time taking and may even involve third-party protection. This comes off as an inefficient way of protecting your eBook when you can simply create UPDF files with PDF Unshare and ensure 100% protection of your eBook from illegal sharing and piracy.

What is PDF Unshare

PDF Unshare is a free tool to protect your PDF files from sharing, editing, copying and unauthorized opening of the PDF document. While most of these features are available automatically on this encryption and protection tool, the users can alter the features depending upon their needs and requirements. Each one of the encrypted PDF and UPDF files can be accessed only on a single device.

PDF Unshare doesn't use passwords for PDF and UPDF file protection as passwords can be easily shared between individuals and groups and hence do not ensure complete security. It uses special keys which are shared over web servers only to the authorized devices. The protected files can be opened only on the UPDF reader program which is available for free on all three prominent operating systems like Windows, Android, and iOS.

Difference between UPDF and PDF files

Since there are two types of file extensions offered by PDF Unshare in the form of .PDF and .UPDF, it is important to know the difference between the two file types. UPDF is a special document format created exclusively by PDF Unshare. This file type requires the UPDF Reader program to open the UPDF files. It cannot be opened on standard PDF reader programs.

On the other hand, PDF file type is offered by PDF Unshare to make the protected file compatible with standard PDF readers like Acrobat and Foxit PDF. In this type of file, the UPDF link is available in the content and directs the users to open the file with UPDF Reader.

4. Find the "Expiration Date" option and click on it to set the date for the expiration of the eBook PDF document. The advantage of setting the expiration date is that the viewers cannot change this date and time at their end and the eBook PDF will expire whenever the current date bypasses the expiration date that is set.

6. Review the created file in the UPDF Reader program and send it to the person with whom you would like to share it. Once the viewer opens the eBook PDF on his device, the document cannot be opened or viewed on any other device. The device that created the UPDF file doesn't get included in the list of restricted devices. If the file is copied or transferred on other devices, then there will be an error message saying that the opening of the file is not allowed on that device.
