2: Blue Spike's Digital Watermarking Emerges as the
Rational Choice for Fighting Piracy
The prerequisite of information security for electronic commerce
has engendered the development of a number of useful technologies,
each with its own strength and each with its own inherent focus.
The three technologies that are being proferred as copyright and information
control mechanisms for e-commerce are:
|
- Digital Rights Management
(DRM) systems
These are object-centric access control systems that primarily
wrap content in protective layers of cryptographic shielding.
DRM does not inherently provide for audit trails once the content
has been rendered, seen or heard. Any DRM is comparatively weighted
down by excessive computational resource use and can easily be
replaced by "DRM-lite" type systems such as the "Trusted Transaction
Server".
- Public Key Infrastructure
(PKI) schemes
These are, broadly put, user-centric access mechanisms to authenticate
the identity of networks users and ascribe each privileges appropriate
to his user profile.
- Digital Watermarking
The systems pioneered by Blue Spike, Inc. invisibly bury the identity
of the copyright holder into the intellectual property object,
such as a song or an image. As well, watermarking systems are
being used as copy control and playback control schemes being
standarized by the consumer electronics and media industries originally
through the Secure Digital Music Initiative (SDMI),
but legislative action in the US Congress as well.

Of
these three, only digital watermarking does not default toward restricting
access as its core functionality.
In the context of delivering various kinds of information and content,
DRM and PKI proffer keying systems to assure payment or end-user privileges
are in place before releasing content or software for consumer use.
Each of these systems have their own relative strengths in particular
domains, though DRM and PKI, given the sophistication required to
use and manage them, are most relevant in the commercial sector.
In consumer markets, however, digital watermarking's simplicity
and technical elegance qualifies it as the most appropriate technology
for the domain. Let's compare.
DRM schemes, if properly, deployed, can be powerful access control
mechanisms for creators and distributors that require absolute certainty
of information security and highly particularized control of their
intellectual property (Bob can view document, but not before the embargo
date, and he cannot e-mail it and cannot print it.) PKI can provide
reliable delivery of information to individual users of a PKI and
a highly secure transfer medium. Yet PKI systems were envisioned primarily
as network access control systems. They can mediate the transfer of
information by way of the cryptographic systems that are organized
by the PKI. Content encrypted for an authorized network user with
his public key acquired through the PKI can only be decrypted by his
private key.
It is true that there are business rationales for secreting
information being transfered from point to point. But in the context
of creating and cultivating markets, opacity is by definition dysfunctional.
Containerizing content and forcing consumers to negotiate payment
and usage rights before discovering it and enjoying it eliminates
opportunities for spontaneous arousal and impulse provocation so necessary
for marketing images, music and other entertainments. A system for
trust, or a "trusted system", is inherently command-based and increases
the likelihood for systemic failure since media content requires open
and accessible means for recognition in order for markets to work
correctly.
The logistics of key-based systems are daunting. Requiring the
consumer to provide the right key to access its corresponding object
- a song, for example - is itself an enormous complexity.
Making sure that the keys are accessible wherever a song is going
to be played is yet another complication, one that becomes increasingly
knarly as content is moved from CD to PC to handheld digital players
like Diamond Rio and RCA Lyra. Cryptographically based access control
schemes, in addition, are computationally demanding, placing them
at odds with consumers' interests when there is limited computing
power available - as in the case of portable players - resulting in
degraded performance and a negative usability profile.
Last, and most importantly, these kinds of schemes do nothing to stop
the capacity of ardent infringers from making and distributing unlicensed
copies without further technologies to hamper them. Thus, they are
exposed to copying, either by acoustic pick-up device or through direct
recording of the music at the twisted pair. Put a jack on the end
of it, put it into a sound card and a quality copy can be made for
distribution on the Internet.
