PDF Unshare is a free PDF copyright protection option that encrypts PDF and UPDF files with permission and authorization settings to prevent sensitive information from being printed, edited, and copied by unauthorized users.
Aimed at organizations looking for easy-to-use encryption solutions to protect sensitive data, this software does not use passwords to protect PDF files. They can easily be shared or removed by cracking programs. Instead, PDF files are protected using individual encryption keys relayed to authorized devices from a web server and encrypted in a key store on the local device. The key store is locked to individual devices, so it cannot be copied and moved elsewhere.
PDF Unshare provides numerous security features and in-built restrictions to protect PDF files. Most basic protection features are applied by default (restricted user access), while others can change to suit their requirements. These security restrictions enable users to stop PDF files from being shared with unauthorized users, control how they are used and the length that authorized parties use them.
Once a document is run through and encrypted with PDF Unshare, UPF Reader must view the document. Any unauthorized user attempting to view the document will be greeted with a locked page.
PDF Unshare offers a secure solution to PDF copyright security to the general public and professionals and is designed to be a real alternative to Adobe.
Key features of the PDF Unshare software include:
Programmatic protection (encrypt) of PDF files with specified RMS rights policies. Shields the implementation details, allowing the user to protect and unprotect PDF files programmatically using a single application.
Application of dynamic security watermarks. Users can set the security watermark text and color for the PDF to prevent copying file content via screenshots, mobile phone cameras, video capture, or other similar methods.
Generation of activity log files that keep a history of which files are protected/unprotected and protected/unprotected.
Restricted user access. Restricts authorized access to a single Windows PC/laptop or iPhone/Android device.
Enable document publishers to expire PDF files so that they can no longer be viewed after a certain amount of time.
The free version is fully functional for personal use. However, if you want to use it for commercial purposes the cost is $49.95 per year. It then provides Priority Processing and Tech Support.
