Movie DRM

The movie industry has used a variety of DRM schemes over the years
to stem the worldwide problem of movie piracy. Two of the major
technologies used to protect mass-distributed media are as follows:

High-Bandwidth Digital Content Protection (HDCP) Provides
DRM protection for content sent over digital connections including
HDMI, DisplayPort, and DVI interfaces. While this technology is still
found in many implementations, hackers released an HDCP master
key in 2010, rendering the protection completely ineffective.

Advanced Access Content System (AACS) Protects the content

stored on Blu-Ray and HD DVD media. Hackers have demonstrated
attacks that retrieved AACS encryption keys and posted them on the
internet.

Industry publishers and hackers continue the cat-and-mouse game
today; media companies try to protect their content and hackers seek
to gain continued access to unencrypted copies.

E-book DRM

Perhaps the most successful deployment of DRM technology is in the
area of book and document publishing. Most e-books made available

today use some form of DRM, and these technologies also protect
sensitive documents produced by corporations with DRM capabilities.

All DRM schemes in use today share a fatal flaw: the device

used to access the content must have access to the decryption key.
If the decryption key is stored on a device possessed by the end
user, there is always a chance that the user will manipulate the
device to gain access to the key.

Technology (ADEPT) to provide DRM technology for e-books sold in a
