Subject: [DMCA-Activists] MS DRMOS Palladium -- The Trojan Horse OS
From: "Jon O."

Reviewing the Microsoft DRMOS (Palladium Patent) it became
apparent Richard Stallman's short story, The Right to Read
is indeed visionary. Below are quotes from the DRMOS patent
and Stallman's Right to Read.
You must read this story:
Although it has been difficult to clearly articulate to the general
computer user, it should now be clear the DMCA represents not
only risk to fair use and other such issues, but represents
a tool by which new technologies such as the DRMOS can be enforced.
It and other new laws (SSSCA/CBDTPA) are the legal infrustructure
required to make the public use these new DRM technologies and
enforce punishment/fines when they are circumvented.
Content from MS DRMOS Patent quoted under the practice of fair use
for comment and discussion purposes.
The DRMOS Patent can be found here:
The Content Provider (ISP) must maintain a registry of "subscriber
computers". This is the SPA and Central Licensing:
Therefore, the content provider would have to maintain a registry
of each subscriber's DRMOS identity or delegate that function to a
trusted third party. ... Because the basic DRMOS and additional
components always have the same identities when executing on a
specific type of processor, the content provider has only to maintain
a list of the identities for the combinations of the basic DRMOS and
additional components that the provider trusts. Each identity uploaded
is then checked against the list.
Soon, changing your PC's system clock could become illegal:
This alternate embodiment requires a secure time source to be
available on the subscriber computer so the user cannot simply
turn back the system clock on the subscriber computer.
Pay-per-use operating system and components:
As described above, components may be valid only until a specified date
and time, and content may also be licensed only until a certain date and
The monotonic counter described earlier can also be used to ensure that the
computer's clock cannot be set backwards to allow the replacement of a
trusted component by an earlier, now untrusted version.
Stallman is right again, DEBUGGING IS NOW ILLEGAL, enforced under Section
1201 of H.R. 2281 (The DMCA):
An example of one kind of procedure that must be prohibited is loading a
kernel debugger because it would allow the user to make a copy of the
content loaded in memory. If the user of the subscriber computer attempts
to load a kernel debugger into memory, the DRMOS can either 1) refuse
to load the debugger, or 2) renounce its trusted identity and terminate
the trusted application that was accessing the content before loading
the debugger. In the latter case, the memory must also be purged of the
content before the debugger is loaded.
See The Right to Read, Stallman:
There were ways, of course, to get around the SPA and Central Licensing.
They were themselves illegal. Dan had had a classmate in software,
Frank Martucci, who had obtained an illicit debugging tool, and used
it to skip over the copyright monitor code when reading books. But he had
told too many friends about it, and one of them turned him in to the SPA
for a reward (students deep in debt were easily tempted into betrayal).
In 2047, Frank was in prison, not for pirate reading, but for possessing
Dan would later learn that there was a time when anyone could have
tools. There were even free debugging tools available on CD or downloadable
over the net. But ordinary users started using them to bypass copyright
monitors, and eventually a judge ruled that this had become their principal
use in actual practice. This meant they were illegal; the debuggers'
were sent to prison.
You can no longer delete specific data from your hard drive:
For example, the DRMOS can allow the user to delete an entire content file
not a portion of it. Another example is that the DRMOS can allow the user
terminate all the threads of execution for a trusted application but not
a single thread.
Again, debuggers are not permitted:
Finally, a DRMOS must protect the trusted application itself from
The DRMOS must not allow other processes to attach to the process executing
the trusted application. When the trusted application is loaded into
the DRMOS must prevent any other process from reading from, or writing to,
the sections of memory allocated to the trusted application without the
permission or cooperation of the trusted application.
Users may not share data:
Such a facility is used when downloaded content can be accessed only by a
particular user. Moreover, if downloaded content is to be accessed only by
a particular user and by a particular application, the secret to be stored
may be divided into parts, with one part protected by an
application-specific key and the other part protected by a user-specific
Applied to Stallman's Right to Read. Bear in mind these are e-books and
would be a form of copyright circumvention:
He had to help her--but if he lent her his computer, she might read his
Aside from the fact that you could go to prison for many years for letting
someone else read your books, the very idea shocked him at first. Like
everyone, he had been taught since elementary school that sharing books was
nasty and wrong--something that only pirates would do.
The "Key Vault" and trusted third party (Central Authority):
Once the data is encrypted using the storage keys, there must be a way to
recover the keys when the DRMOS identity changes (as when the operating
is upgraded to an incompatible version or an unrelated operating system is
installed) or the computer hardware fails. In the exemplary embodiments
described here, the keys are stored off-site in a "key vault" provided by a
trusted third party. In one embodiment, the DRMOS contains the IP addresses
of the key vault providers and the user decides which to use. In another
embodiment, the content provider designates a specific key vault and the
enforces the designation. In either embodiment, when the user requests the
restoration of the storage keys, the key vault provider must perform a
amount of validation before performing the download.
Your computer cannot be used to copy content:
For example, one property might be that the application cannot be used to
copy content. Another example of a property is one that specifies that the
application can be used to copy content, but only in analog form at 480P
resolution. Yet another example of a property is one that specifies that
the application can be used to copy content, but only if explicitly allowed
by an accompanying license.
Looks like the MPAA has been engaged in some Retail Politics:
In one embodiment, the access predicate takes the form of a required
access control list (ACL) as shown in FIG. 10. The required properties ACL
contains a basic trust level field 1001, which specifies the minimum rights
management functions that must be provided by any application wishing to
the content. These minimum functions can be established by a trade
such as the MPAA (Motion Picture Association of America), or by the DRMOS
More Pay-per-view OS functions:
As described briefly above, the license data structure 1100 can limit the
of times the content can be accessed (usage counter 1101), determine what
can be made of the content (derivation rights 1103), such as extracting
shots from a video, or building an endless loop recording from an audio
or a time-based expiration counter 1105.
The sublicense rights 1107 can impose more restrictive rights on
content than those specified in a license for content downloaded directly
the original content provider. For example, the license 1100 on a song
directly from the music publisher can permit a song to be freely re-played
the sublicense rights 1107 require a limit on the number of times the same
can be re-played when redistributed.

Fair Use -
because it's either fair use or useless....
