The Convergence of Anti-Counterfeiting and Computer Security
-
Description
-
This talk examines the similarities between computer security andoptical document security. Also we describe our work on reverseengineering anti-counterfeiting measures, included in much moderngraphics software, and discuss its impact on Open Source.about this event: http://www.ccc.de/congress/2004/fahrplan/event/108.en.html

Since January 2004, many major graphics software and hardware manufacturers have included anti-counterfeiting measures in their products (including Adobe Photoshop, JASC Paint Shop Pro, HP Printers and Canon scanners). The feature operates by detecting characteristics of banknotes and preventing a suspicious image from being processed. The software is developed by the G10 Central Bank Counterfeit Deterrence Group and provided to manufacturers as a compiled library. No details of the what features the system detects are publicly available, and it has been established that it does not use the same counterfeit-deterrence technique used in colour photocopiers.
Firstly the lecture will include background information on existing counterfeit deterrence systems, designed to prevent currency being copied on conventional printing equipment. This will move on to the more modern techniques, developed in reaction to the widespread deployment of high-quality digital printing hardware. Also the field of digital watermarking will be introduced and its relationship to counterfeit deterrence discussed. The lecture will cover the progress of a project to understand the currency detection feature, and reverse engineer it. This includes conventional reverse-engineering techniques such as disassembly and dynamic code analysis, but it will also describe application specific tools, such as black box digital watermark benchmarking.
Finally, proposed EU legislation will make the inclusion of such a system mandatory, so the consequences on Free and open source software will be discussed. These are in addition to conventional DRM problems such as prevention of legal manipulation of currency images, and other problems specific to counterfeit deterrence.
