Re: Copyright protection... HOW???

The only possibility I could think of making copying harder would be to
use a hardware-based data hash for en/decryption. Since someone has
reading access to the plaintext while presenting, this plaintext still
can be piped somewhere else, but that would be quite an effort on a M$
so-called operating system. On the other hand it would be easy to read
let's say the PC's MAC-address and use it's hash as a key. If you don't
have a programmable MAC address on your computer, you won't be able to
decrypt the file without writing your own decryption routine based on
the reverse-engineered original program and the knowledge of the given
MAC address (your routine wouldn't be open source of course, since this
would contradict your principle "don't let anyone use what you have
created", what makes the implementation quite a bit of work), which is
most likely not worth the trouble for an attacker. The only question is
if your content is worth the trouble of the encryption, but you are the
only one who can answer *that* question.

Of course, there is another, much easier possibility: you explicitely
allow redistribution and usage under the terms of a fair and free
license; this way, no one will be attempted to use your content without
permission but will rather add your name and do it legit, hopefully
bringing the world a bit closer to perfection (remermber: your content
is capable of this, otherwise you wouldn't have considered "protecting" it).

Kind regards,
