If you loose your PDA or get it stolen... you're toast. You might as well hand out your credit card... :roll:
Ahhhh, classic JLP. Another rant based on an incorrect assumption with no basis in fact. :roll:

That isn't how it works. They take your name and CC# when you buy the book and run it through a series of mathematical formulas and come up with a one way hash. The OWH goes into the book. You can't extract the CC# or name from the OWH, that is why it is called one way.

Then, when you get the ebook, you put your CC# and name into the eReader software. It has the same formulas in it and it genrates a OWH. If it matches, the ebook is opened. If not, then it isn't. You can read more about it here on PPCT or in this .ebook thread on usenet where Peter Fry, a former programmer at Palm Digital Media/eReader talks about the OWH the software and server uses.
