Ebook Encryption and E-Book DRM
Encrypt ebooks with ebook encryption software
What is ebook encryption?
Ebook encryption is the process of applying encryption technology to an ebook to render it unusable to anyone without a key to decrypt it.
However, once someone has the decryption key they have complete control over the ebook. So you must apply additional controls to stop users sharing ebooks and keys with others, lock use to authorized devices only, and stop editing, copying and printing.
Types of ebook encryption
When encrypting an ebook you need to think about usability. For one thing, while encrypting the ebook may seem a straightforward process you have to consider how you are going to deliver decyryption keys to users, what software is going to decrypt the ebook so that it can actually be read, and how you are going to control use (stopping sharing, printing, etc.) once the book is decrypted. As a result, ebook encryption is not quite so straightforward.
You could use any encryption software to encrypt an ebook such as the well recognized encryption/decryption standard OpenPGP. However, you need to be aware of the fact that you do not have any digital rights management (DRM) controls as a result of using this type of encryption and therefore cannot control use of your ebooks once an ebook is decrypted. The OpenPGP encryption approach is simply used as a means of ensuring that only those authorized are able to decrypt information. It does not impose any controls on what can be done with the ebook once it is decrypted.
So ebook encryption is not a method for controlling the use and distribution of ebooks, although it may be appropriate as a technique for transferring a draft ebook from the author to an editor or proof reader and back again. Encryption protects information from access by anyone who is not authorized, but allows the authorized to do anything they like with the information – it has not concept of controls that note when an ebook is copied, printed or otherwise used.
