Digital Media Equipment Self-Encryption (DMESE)

Talk of "managed copy" for DVD's in the news has me talking about an
idea I had back in January for stopping casual copying which is simply
having the equipment encrypt its copies to itself. That is, when you
make a backup copy, say of a DVD, your copy is encrypted by your
machine so no other can read it would a key, which can be passed by a
flash drive so you can use your backup copy with all your own
equipment.

It might also be passed over your network.

To make this idea a complete end to end solution, say, when you buy a
copyable DVD, it might come with a flash drive that would allow you to
use one device to copy it, as it would read the key from the flash
drive which would then be wiped, which would prevent you from just
passing the original bought DVD as a master for others to make copies.

Regardless of various implementations as you could different things to
get various protection schemes as this idea is very flexible, the one
key thing is self-encryption by your digital media as it would encrypt
copies it made to itself.

So all copies would be encrypted with keys that could vary potentially
with every single copy.

The biggest issue for the various industries from the movie to the
music industries getting this idea going would be the need for
manufacturers of the primary devices like DVD and CD drives to make
their drives smarter to implement it, and maybe have them take flash
drives to pass the keys.

Having a hardware solution makes it that much harder for criminal
copyright violation as people would need bootleg non-industry standard
DVD drives to not use DMESE, which themselves could be made illegal as
their primary purpose would be for illegal activity.

I talk more about this idea on my blogs, here's a link to one:

I have given the idea away open source.

It is a free idea, though if anyone bothers to use it, they should
cite me as the source of the idea.
