Our latest innovation named DiscKeeper Netlock is the ultimate solution to protect your e-books and Multimedia contents over the internet. DiscKeeper Netlock will safely encrypt your existing PDF and other multimedia files like MP3, MPG, FLV, SWF, WMA etc within a Windows program. The native applications in the client system like Adobe Reader or Windows Media Player can play the file, but SaveAs, Copy, Paste, E-mail, Print etc will be disabled, thus making it a truly read-only or play-only file.

When the client purchases the book the respective file is downloaded and a one-time activation key is generated by our secure servers which will only work for his computer. If it's opened from a different computer, the application will only show a sample of your file! At your discretion, Netlock can even allow a client to install his book on more than one computer - you decide the limit.

With Netlock it is easy for you and for your clients.
