Up until the early 90's, work in digital watermarking of
multimedia works was limited to university research labs. The first successful commercial venture that
I'm aware of was Digimarc, founded in 1995 by Geoffrey Rhoads. The basis for the business was a novel
digital watermarking technology for which Mr. Rhoads had just filed for patent
protection. Digimarc was developing still
image watermarking products for the professional photographer to protect
against theft. Around the same time,
interest in watermarking had spread to industry research labs including NEC,
IBM, and Philips. The big push came from
the Motion Picture industry. The industry
consortium responsible for establishing the DVD standard selected CSS
encryption for DVD content and included a watermarking "hook" in the CSS
license. Looking ahead to DVD recording,
the license required all licensees to implement watermark detectors in their
DVD players at some time in the future when the consortium selected an
appropriate watermarking technology. The
idea was to prevent normal DVD players from being able to play pirated DVD
content.
This spawned a frenzy of activity, as many companies tried
to develop the appropriate watermarking technology that would become part of the
DVD standard. This frenzy extended to
university campuses and the research field grew quickly. Many startup companies were formed, marketing
their technologies to professional still image photographers. Other companies developed watermarks for
audio. The big companies involved in the
DVD competition, targeted video. These
companies included NEC, IBM, Sony, Hitachi, Pioneer, Philips, and others.
Most of the small start-ups disappeared. Turns out, professional photographers don't
really have a problem with piracy - at least not one that needs a technical
solution. There was some consolidation
in the audio watermarking field with Verance emerging and still around. Of the large companies in the field, Philips
was the sole hold out, all others abandoning their efforts shortly after it
became evident that inter-company politics would prevent any watermark from
being adopted for DVD. Verance was
successful in getting its audio watermark into AACS, the copy protection system
used by Blu-ray Disc. And Digimarc,
although they no longer sell shrink-wrapped watermarking products to consumers,
maintain a small watermarking-as-a-service business, provide watermarking technology
to government clients, and maintain a significant patent licensing
business. If they can't make money
selling watermarking products, they will make money licensing their patents to
other folks who won't make money selling watermarking products.
While most of the big companies were exiting the field,
Thomson entered it in 2005 by purchasing two small watermarking startups,
MediaSec in Germany and NextAmp in France. The last holdout of the big boys
from the DVD days was Philips and in late 2008 they spun out their content
protection business as Civolution. That
left Thomson, which held on until July of this year when they sold their
watermarking business to Civolution.
So, what is next? The
initial excitement around digital watermarking was as an anti-piracy technology. There were a number of problems with
this. Most importantly, the piracy
problem is deep and cannot be solved by technology alone. Since the industry was singularly focused on
the piracy problem and their interest in watermarking was only as a tool to
solve that problem, interest quickly waned.
However, I believe that the focus on piracy overwhelmed other
potentially exciting applications. Civolution
appears to be broadening their scope, looking at use of watermarking and
fingerprinting to manage content and to create new revenue streams. Verance is also pushing content management
applications of their audio watermarking.
In 2000, Digimarc started looking at the use of watermarking to create a
bridge between the printed page and internet, a theme they continue to press. Now that some of the hype has died down,
there's room for creative new applications of a magical technology.
