The 2010 Conference on Optical Security and Counterfeit Deterrence took place in San Francisco from 20 - 23 January. The preparations for this conference in cooperation with Reconnaissance International (UK) started early 2009. With 250 attendees and 38 interesting technical presentations the conference was again very successful.
For conference details, see the Conference Website.
Part of the Conference Optical Document Security 2010 was a half-day course on Optically Variable Devices on January 20, 2010.
This course was attended by 60 conference delegates and highly valued. The presentation is made available for the course attendees on CD-ROM. For details see the Conference Website.
The overriding duty of an expert witness is to the Court, by providing knowledge in a fair and impartial manner. It is the duty of an independent consultant to provide such services without any affinity to one party or another. It is also the duty of an expert witness to carry out adequate research.
VanRenesse consulting abides to this credo.
Since 2006 Van Renesse is active as an independent expert witness in several legal cases and these expert witness obligations continue into 2010.
These expert witness projects comprise reporting on the analysis of technical backgrounds of patents and their prior art, literature research, and laboratory research.

A four-day course has been presented in November 2008 for the Guardia Civil in Madrid, Spain.
The course comprised:
. Theory of Colors
. Video Spectral Comparator
. Printed Security Patterns
. Optically Variable Devices
A security evaluation of a novel security technology was carried out in September 2008 for a multinational company with headquarters in the USA.
The evaluation comprised an analysis of the merits of the technology and its resistance against counterfeiting, replication and imitation.
A series of technical articles was written for Reconnaissance International's Holography News and Currency News on various document security aspects.

The 2008 Conference on Optical Security and Counterfeit Deterrence took place in San Francisco from 23 - 25 January. The preparations for this conference in cooperation with Reconnaissance International (UK) started early 2007. With 220 attendees and a great many interesting technical presentations the conference was highly successful.
For details, see the Conference Website.
Part of the Conference Optical Document Security was a half-day course of the same name on January 23, 2008. This workshop was a continuation of the workshops given at the earlier biannual San Jose conferences on Optical Security and Counterfeit Deterrence Techniques. This fully updated course was attended by 74 conference delegates and highly valued. The presentation is made available for the workshop attendees on CD-ROM. For details see the Conference Website.

An extended course on the security aspects of holography has been presented in July 2007 for a National Mint of a country of the European Union. The course comprised five days and introduced diffraction and interference type phenomena and treated numerous security aspects of iridiscent optically variable security features. Hands on demonstrations of various optical effects and security features were given.

In 2006, for a Ministry of Internal Affairs in the Pacific Territory, a three-day workshop was attended as an advisor on the development of a new national travel document.
Apart from discussing the pros and cons of a host of document security features, attention was drawn to the necessity of developing a Program of Requirements that does not set hard specifications for certain security features, but leaves room for an independent proposal.

In the course of time various projects involved the quality evaluation of security features on currencies. Security feature characteristics that were analyzed, comprised magnetic ink signal, fluorescent printing brightness, latent image visibility, holographic stripe quality, and intaglio relief height measurements.
These projects were carried out for IGT Testing Systems, Amsterdam, The Netherlands and Schell Consulting, Noordwijk, The Netherlands.
In 2005 a patent analysis was carried out for a USA customer. The work concerned a novel security feature of the non-iridescent optically variable type. The evaluation comprised a comparison with prior art and providing technical background information for the assessment of the novelty of the invention.

This was originally intended to be a presentation on the then recent high-quality euro 200 counterfeits. In deliberation with the European Central Bank this subject was not touched.
The Counterfeiting Intelligence Bureau, part of the Commercial Crime Services division of the International Chamber of Commerce (ICC) in London has a UHS available, a forensic tool for analyzing holograms. In 2004 a UHS investigation was carried out on various counterfeit holograms, including counterfeit Euro holograms. A report of the UHS and various test results are reported in the paper Testing the Universal Hologram Scanner - A picture can speak a thousand words.
Making a decision, when many parameters are involved, can only be done efficiently and reliably with the use of MCDA software.
In the period 2003-2004, using dedicated MCDA software an elaborate decision model was built that allowed a USA customer to decide which security feature to choose for an application in the field of product security.
On various occasions the security of PIN-mailers and refill vouchers has been extensively investigated for different customers. PIN-mailers are envelopes containing a PIN-code that is mailed to bank customers. Refill vouchers contain an upgrade code for cell phone balance. The investigations involved the resistance of the code containing envelopes against various forms of fraud and forgery.
In 2004, for a Dutch customer, research was carried out on the Internet, in literature and patent databases in order to find possible novel applications of the security technologies provided by the customer. The research involved optics, mechanics and software aspects of the application.
In 2003 an independent analysis was carried out for Pitney Bowes (USA), on the security value and marketing size of a novel ink formulation. The study established the relevant areas where these inks are penetrating, approaching key consumers in the field with a questionnaire, assessment of the security value of the novel ink and the possible size of the market.
In 2003, a feasibility study was carried out for Orbid corporation, concerning the inerasable application of high resolution, high temperature resistant, covert codes on glass and the availability of readers for such codes.
This study involved internet and patent research and interviews with printing ink manufacturers, and specialists in printing and glass marking techniques.
In 2002, for a client in Germany, an independent analysis was carried out of an identification document security feature. A relevant range of security features, used in 47 European countries, was taken into account for this comparative analysis. Considered were security aspects, security of source and distribution, quality aspects, human factors and marketing prospects.
