1. What is Adobe DRM?

What is Adobe's ADEPT DRM?

ADEPT (Adobe Digital Experience Protection Technology) is the DRM (Digital Rights Management) system developed and used by Adobe to protect ebooks. For instance, Google Play books adopt this encryption scheme. Besides, Barnes & Noble (B&N) e-books are also protected with a variant of ADEPT.

In ADEPT, ebooks are encrypted with a book key (i.e. each digital copy of the same book is encrypted with the same key). The distributor picks this key, and encrypts the ebook using that key. At the same time, each user has his own user key. This key is generated when the user installs Adobe Digital Editions (ADE), and is uploaded to Adobe. With Adobe DRM, the software locks content to up to six machines and allows the user to view the content on each of them.

To download content protected with Adobe DRM, you need the Adobe Digital Editions eBook viewer and authorize your computer using the Adobe ID before downloading them.
