A Princeton University student has published
instructions for disabling the new anticopying measures
being tested on CDs by BMG--and they're as simple as holding
down a computer's Shift key.
In a paper published on his Web site this week, Princeton
Ph.D. student John Halderman explained how he disabled a new
kind of copy-protection technology, distributed as part of a
new album by BMG soul artist Anthony Hamilton.
Under normal circumstances, the antipiracy software is
automatically loaded onto a Windows machine whenever the
Hamilton album is run in a computer's CD drive, making
traditional copying or MP3 ripping impossible. However,
simply holding down the Shift key prevents Windows' AutoRun
feature from loading the copy-protection software, leaving
the music free to copy, Halderman said.
The technique was confirmed by BMG and SunnComm
Technologies, the small company that produces the
anticopying technology. Both companies said they had known
about it before releasing the CD, and that they still
believed the protection would deter most average listeners'
copying.
This is something we were aware of, BMG spokesman
Nathaniel Brown said. Copy management is intended as a
speed bump, intended to thwart the casual listener from mass
burning and uploading. We made a conscious decision to err
on the side of playability and flexibility.
The ease with which Halderman and others have disabled
BMG and SunnComm's latest copy-protection techniques
illustrates the delicate balance that record labels and
technology companies are trying to strike in protecting
content without angering listeners.
SunnComm's technology is the
most flexible version of CD copy-protection to hit the
market yet. It includes "pre-ripped" versions of the
songs on the CD itself, each of which can be transferred to
a computer, burned to CD several times, or transferred to
many kinds of portable devices. These differ from
unrestricted MP3 files in that only limited copies can be
made, and not every portable music device can play them.
The Anthony Hamilton CD is the first release in this new
generation of copy-protected CDs that come preloaded with
these "second session" tracks designed for use on a
computer, a strategy also being pursued by SunnComm rival
Macrovision. Record labels have pushed for these tracks,
mostly provided in Microsoft's Windows Media format, to be
included on copy-protected CDs in order to ameliorate
consumers' concerns about not being able to use their music
on computers.
SunnComm CEO Peter Jacobs said the technology--which will
be improved in future versions--should still be attractive
to record companies. Though simple, the act of holding down
the Shift key in order to enable copying does let computer
users know they're doing something unauthorized, he said.
That alone will dissuade many people from making copies, he
added.
This is not an all-or-nothing thing, Jacobs said.
People can break into your house, because there's lots of
information out there on how to pick locks. But that
knowledge doesn't mean you don't buy a lock.
In order to fully prevent the antipiracy software from
loading, a listener has to hold the Shift key down for a
long period of time, at exactly the right time, every time
they listen to the CD on a computer. Moreover, anyone who
doesn't load the software won't get access to the second
session tracks, which on future CDs will increasingly
include videos and other bonus material, record company
insiders say.
For his part, Halderman says the workaround is so simple
that it's hard to fix. Nor is he worried about falling afoul
of laws that make it illegal to describe how to get around
copy-protection measures.
I hardly think that telling people to push Shift
constitutes trafficking in a (copy-protection technology)
circumvention device, Halderman said.
I'm not very
worried.
