Hello lauriefree,

Thank you for your questions!

"MPAA targets boy scouts with anti-piracy campaign"

The Los Angeles area Boy Scouts (with about 52,000 youngsters) have
teamed with the MPAA (Motion Picture Association of America) to teach
their Scouts about copyright and that piracy is a crime.  The Boy
Scouts say that they approached the MPAA about the project and that
the MPAA did not make any kind of financial donation to the Boy Scouts
to begin the project.  The inspiration came from Hong Kong Boy Scouts,
who pledge not to download, use or buy pirated material.  In Hong
Kong, the boys are also encouraged to surf websites and turn in
pirates to their Scout leaders, but this will not be a requirement of
the American version of this program.

The curriculum of the teachings has been written in a joint effort
between the MPAA and representatives of the LA-area Boy Scouts.  The
curriculum will be made available to other California Boy Scout
councils beginning next year.

"MPAA has already formed a curriculum with the Los Angeles Area Boy
Scouts that met the approval of troop leaders in the greater Los
Angeles area earlier this year. The idea of the curriculum is to teach
participants about copyright theft and various forms of piracy, how to
spot counterfeit CDs/DVDs, the consequences of film and music piracy,
and also why protecting copyrights is important to them and the local

Scouts will have the opportunity to earn a "Respect Copyrights" patch.
 Activities that could go towards earning the badge include making a
public service announcement promoting copyrights, looking at a website
to identify which files are copyrighted and which or not, or visiting
a local film studio to see how movies are made and their importance to
the Los Angeles economy.  The awarded badge features a film reel, a
compact disc, and the copyright symbol (a c in a circle).  A picture
of it can be seen here:

It is not a "merit badge" but will be known as an "activity patch."  

"3. Catalog with a brief history major encryption/unlocking stories on
video encryption. What did they do, how was it beaten, how long did it

Here are some examples that I could find:

Wikipedia entry-- DeCSS

Jon Johansen and two others broke the CSS system used to encrypt DVDs
in Norway in 1999.  They called their system DeCSS.  Johansen was
arrested and tried in Norway on charges, but acquitted.

When the source code of CSS protection was released, many who examined
it found other flaws in the protection and thus many ways to decrypt
CSS were born from this case. Today there are many programs available
to do so.  Here are a few examples:

"Gallery of CSS Descramblers"

"Two Perl implementations courtesy of MIT Student Information
Processing Board members Keith Winstein and Marc Horowitz. The shorter
one, qrpff, is 472 bytes (discounting newlines). The faster one, 531
bytes long, caches the permutation corresponding to CSStab1, and is
actually fast enough to use to watch a movie. The program takes a
five-byte title key on the command line (five decimal numbers in least
to most-significant order, separated by colons) and an MPEG2 Program
Stream VOB file on stdin, and outputs a decrypted version of the VOB
file. Title keys can be obtained using VobDec."

"This tiniest known C implementation, now just 434 bytes (discounting
newlines), is also plenty fast. It originated with Charles M. Hannum,
who then shrunk it further, and got additional suggestions for
shrinkage from Phil Carmody. Mr. Hannum writes: "on my Mac G4 cube
(running NetBSD, not MacOS), it can descramble in excess of 15MB/s
[better than 10 times maximum DVD bit rate], ... without even
particularly trying to optimize the I/O. This makes it pretty
insignificant compared to the rest of the decoding process." He
performed these measurements using artificial data; he would of course
be in violation of 17 USC 1201(a)(1) if he used the code to watch a
movie he had lawfully purchased."

Slashdot-- "Work Around for New DVD Format Protections"
Heise Security--  "Copy protection hole in Blu-ray and HD DVD movies"

AACS is the new copyright protection method which will be utilized for
next-generation DVDs.  AACS has not been broken, but a workaround has
been found in which a program written can use the Windows Print Screen
button to copy any DVD that is playing and using AACS.  Johansen is
also apparently working on defeating AACS with a software called
DeAACS.  This loophole was found by C'T Magazine.


Windows Media Player DRM:
FairUse4WM was released in August 2006. It is a program that strips
WMP of its DRM protection.  Windows released a patch that disallowed
the use of FairUse4WM nine days later.  FairUse4WM released a new
version that circumvented the new patch within three days.  Microsoft
has filed lawsuits against offending websites such as Sky by
Broadband, but it has not released further patches.

DVD Jon has done it again. In October 2006, Jon Johansen announced
that he has reverse-engineered Apple's DRM coding, called FairPlay, to
allow other companies' movies and media to be played on a person's
IPod without being encoded into Apple's proprietary format.  He will
sell the workaround to interested media companies.

"4. How does Tivo square with DRM?"

Tivo has tried to institute forms of DRM in the past.  Beginning last
year, a Macromedia patch was downloaded onto Tivos which caused them
to not be able to keep pay-per-view shows or video-on-demand past a
certain expiration date.

Last year, some users were told that they could not save shows past a
certain expiration date at the request of the copyright holder.  Not
too many users were happy with this and it was shrugged off as a bug
involving the Macromedia flag by Tivo.

If any studios or companies wanted to enforce DRM standards with Tivo,
they certainly could now that this flag has been put in place.

Here are some posts on this development:

Wired Interview

Tivo Community

"TiVo won't save certain shows or allow moving them"

"TiVo 7.2 OS adds content protection, blocks transfers, and
auto-deletes some shows"

PVR Wire

"5. Are there any plans for implementing DRM on any of the following
formats: Blu-Ray Discs, Holographic Versatile Discs, Protein-Coated
Discs (PCD), or Flourescent discs. If so, what are the plans?"

Blu-Ray and HD-DVDs will indeed be encrypted.  Instead of CSS, they
will be encrypted with AACS, a more secure method which uses a longer
key. It is widely thought in hacking circles that AACS will be broken
just as CSS and other means of copyright-protection have been. In
fact, many believe that copyrights simply cannot be protected in this
way.  However, Blu-Ray includes a dynamic encryption system; if the
keys to its encryption are broken, the keys can be changed in
subsequent releases and updated to prevent further copying. This is a
big improvement over CSS, which once broken was always broken.  It
also includes a Mandatory Managed Copy protection which allows the
disc to be copied a certain number of times, provided that the person
has the correct key that they obtain from the owner of the content
included on it.  The methods used are controversial because if a DVD
player has played a cracked DVD, that DVD player can be shut off and
disallowed from use remotely.  Blu-Ray also includes a digital
watermark which will identify a copy as being illegally made from a
theatrical release.

HD-DVD and Blu-Ray use ICT, Image Constraint Token, which senses an
analog connection and only allows a certain digital output to these
connections. No studios using Blu-Ray have said that they will
actually use this technology, but Warner Bros. has said they will use
it for HD-DVD.

Wikipedia Entry-- AACS

The HVD (holographic versatile disc) has not even been developed yet
as a feasible technology and is still in labs.  It would have to be
much closer to being an actual technology before standards are brought
forth for encryption purposes.  Protein-coated discs are even further
from a possible commercial release and so nothing has been decided in
that category, either.

Flourescent discs were an idea from a few years ago that never really
got off the ground.  The company that owned the technology collapsed
in a scandal after they misreprsented the abilities of the disk in a
presentation at a trade show. They were supposed to hold up to a
terabyte of data.  Companies for now prefer Blu-Ray and HD-DVD
technology.  Flourescent discs can include time-limiting capabilities
that would act as natural protection, but some people claim that this
very fact would limit the adoption of the technology-- people want to
copy DVDs which they own in their own home and wouldn't like a disk
which naturally would not allow them to do so.  The technology is now
being called Digital Multilayer Disc and a new company is trying to
market it.

Yes! Good stuff at great speed. I just need another source on the
Protein-Coated Discs (PCD)- something other than Wikipedia that is
reasonably authoritative. Thanks.

Hello lauriefree,

Here are some other resources for the protein-coated discs--



Digg thread

all of these are relatively similar, because this future product
hasn't really come out with anything besides the initial press

I hope that helps!
