Digital Bazaar, of Blacksburg, VA, has
launched a beta version of Bitmunk,
a new P2P file sharing service that the company claims is copyright-respecting.
Bitmunk uses an architecture called Secure File Distribution Network (SFDN),
which includes a micropayment mechanism and home-grown watermarking technology
that deposits the user ID of a downloader into the file at download time,
enabling forensic tracking of the file if it should end up somewhere other than in the
buyer's possession. Like the original Napster, Bitmunk features a central
catalog of works available on the network, while the files themselves reside on
users' computers.
Bitmunk's business model is similar to that of Weed and a couple of others: it is primarily designed
for independent artists, who can put their works up on the network and receive
royalties every time copies of their works are sold. Bitmunk separates the notions of artist and seller:
artists get royalties, while sellers get whatever fees they decide to charge.
One interesting difference between Bitmunk and the other services is that Bitmunk gives artists flexibility in
defining what rights they wish to make available -- standard copyright bundle,
copyright with redistribution rights, public domain, or a number of Creative
Commons licensing options.
But is Bitmunk truly copyright-respecting? In considering Digital
Bazaar's watermarking technology, our opinion would fall somewhere between "sort
of" and "not really." (A major record label or movie studio would simply
say "no.") Bitmunk's watermarking scheme is similar to that of
Activated Content,
Interoute, and
other services that use watermarking to track limited-distribution content
releases, such as pre-release copies of music tracks sent to critics and radio
stations. If the copyright owner of a work distributed on Bitmunk finds
her file somewhere that it ought not to be -- such as on Morpheus or KaZaA, or
on another user's hard drive -- then she can examine the file and determine the identity of the user who downloaded it.
The content industry would consider this type of watermarking use for general
content distribution to be unacceptable. Digital Bazaar claims that it is
letting its users retain their fair use rights while providing some
kind of channel for addressing infringement claims against users. A Big
Media representative would object that such a channel is not adequate; the whole
idea of encryption-based DRM technology is to proactively inhibit consumers'
ability to copy and send content anywhere at virtually no cost.
Watermarking schemes like that of Bitmunk have been around for a couple of years
now, and the content industries have simply not embraced them beyond the limited
uses mentioned above.
We have been saying for some time that this is the year in which DRM and P2P
move towards each other in the marketplace. MusicMatch, which uses
Microsoft Windows DRM and which
introduced a
limited sharing feature a couple of weeks ago, represents one side, while a
growing number of independent services that feature some sort of protection on
top of architectures that combine file sharing with financial transaction
processing represent the other side. We suspect that Bitmunk will be
one of the latter that will neither attract much attention from nor influence
the direction of the established media industry's future online content services
-- although that may ultimately bother the people at Digital Bazaar not at all.
