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.

How to Download eBooks with Adobe DRM?

You probably have got some eBooks from the internet, or purchased some eBooks from Kobo, Google Play Books, and the publisher gave you ACSM files. ACSM (stands for Adobe Content Server Manager) is not an actual eBook but a link – a link to download the actual eBook in Adobe Digital Editions.

Adobe EPUB/PDF ebooks are protected by Adobe's digital rights management (DRM) system. 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. For detailed instructions, you can follow this step-by-step guide to download ebooks with Adobe DRM.

This program has been awesome so far. It is so frustrating to purchase something and it not really by "mine". This program makes "mine" really be "mine". Thanks!

The problem comes where "mine" really means any one who wants to download it on the internet. Its all ok... until its your book being pirated and then youll feel like the funding proceeds should be "mine" but they wont be, itll be "theirs".
