Joe Winograd (Verance) on Public Assessments Of Watermark Survivability

Back in February I wondered about public tests of watermarking survivability besides the well-known SDMI related tests. Joe Winograd, CTO of watermarking company Verance, emailed the following information:

There have been 5 competitive, independent audio watermark technology evaluations held to date -- a list is provided at the bottom of the "Technology" page on Verance's web site here.
 
Of these, only one (JASRAC/CISAC/BIEM's STEP 2001) has distributed the results publicly.  An archived announcement of the results is here. The three part report is available here, here, and here.

Of the others, IFPI's MUSE results were distributed only to the member companies, 4C's results were provided only to SDMI, and SDMI's reports were distributed to the 200 member companies.  
 
There have been 2 competitive, independent, commercial, video watermark evaluations held that I am aware of (both under the auspices of the DVD CCA) but we did not participate and I don't think any results were publicly released.

Best, - Joe

Digimarc Spins Off ID Business

Watermarking vendor Digimarc has announced that it is selling its ID Systems business to L-1 Identity Solutions Inc. The sale leaves Digimarc free to focus its resources on its digital watermarking and licensing business.

“This relationship comes at a particularly opportune time for Digimarc, as we are experiencing an inflection point in adoption and revenue growth for digital watermarking,” said Davis [Bruce Davis, Digimarc Chairman and CEO]. “Our technology is beginning to permeate the full range of media content, from banknotes and secure credentials to television, movies, music, video games, digital images, advertisements, packaging, and industrial goods. This transaction represents a great step forward for our shareholders, employees, and customers. As we combine our ID Systems assets with global leader L-1 to form a more comprehensive offering responsive to our customers’ evolving needs, we are also redoubling our focus on the realization of our founding vision to making digital watermarking a standard feature in all media content. This is a very exciting moment in our history.”

Seems like a wise move.

Digimarc Conference Call - A Few Tidbits

A lot of the call and questions are focused on the ID part of Digimarc's business including watermarking of media content. Here are some tidbits (paraphrased):

Blu-ray win not relevant to Digimarc since Digimarc is involved in both formats other than greater sales in 08. IP connected entertainment devices will be more important. Technology for identifying media objects will become increasingly important. Final Blu-ray license will require Digimarc watermarking. Probably the middle of '09 before royalty revenue from Blu-ray sales become material to Digimarc's financial results.

Nielson relationship going great. We're in the development stage getting solutions ready for market. They will be Nielson's solutions. We're cranking full speed on it.

What Is Blu-ray Anyway?

Now that Blu-ray has won the HiDef optical disc format war, what is Blu-ray anyway?  Over on CoolGadgets there is a longish posting that provides a good overview, including a quick review of Blu-ray security technologies AACS, BD+, and ROM mark. ROM mark is an antipriracy feature that is a watermark on the physical disc so that players can check on the authenticity of the disc inserted in the drive and then refuse to play titles that lack the proper mark.

Published Assessments Of Watermark Survivability?

The survivability of watermarks has been a hot topic for some time. Some independent work focuses on various sophisticated attacks to remove watermarks, for example, the Craver et al., paper relating to the SDMI challenge.

While there are numerous vendor claims of robustness that may well be true, does anyone know of a published study by independent consultants or academics that demonstrates that at least one commercially available watermarking technology survives digital / analog / digital (D/A/D/ transcoding in either the audio or video domains and/or that survives D/D transcoding (from MP3 to AAC or MPEG2 to MPEG4)?

Wired: DRM Dead, Watermarks Rise From The Ashes

David Kravets writes in Wired that watermarking will replace DRM for music. Maybe. Watermarking is something added to the audio that is below the perceptual threshold, i.e., cannot be detected by the listener. Usually the "something" is a code that identifies the track and/or its owner. In some instances, the watermark may indicate who last created the file. Kravets writes:

DRM 3.0 Has Arrived

Following several conversations with senior executives from several different companies, I've come away from the CES show thinking that the next generation of DRM has arrived. The outlines of DRM 3.0 have been clear for the past several months, but two themes emerged from my various discussions.

The first is that despite the apparent death of DRM in the music world, rights management is being reinvented as network layer and backend sets of processes and services. Network providers will increasingly play traffic cops and apply rules such as "don't allow transmission of the copyrighted material" across our network. Similar functions are being developed / applied in the User Generated Content world (UGC).
