Basically Palladium attempts to let the computer user prove to a
remote computer what program he is running locally. It achieves this
through a rather complex system involving cryptography, secure
hardware, and special extensions to the operating system.
Perhaps the remote server will download some data to the user, but only
to a program which it knows will observe the Digital Rights Management
(DRM) rules built into that data. The user can use Palladium to prove
to the remote system that he is running one of the programs which will
follow the DRM rules. In this way the transfer can go forward on terms
which are mutually acceptable to both parties.
Of course no system is perfect, and it remains to be seen how well
Palladium can implement this somewhat idealized model.
