Short course on Optical Document Security 2008
23 January 2008 - 1.00 – 5.00 pm.
Presenter: Ruud van Renesse, VanRenesse Consulting
The number of different security features for valuable documents and products has mushroomed with the advance of digital colour copying systems since the late 1980s. Efficient countermeasures were developed that made an obvious distinction between genuine products and digital copies. Counterfeiters soon caught up with passable imitations and the race for adequate counterfeit resistance escalated with a pace never seen before, with image complexity and structural complexity as the main defences. Most of these security measures are of an optical nature.
What makes a document a genuine one? There is no single security feature yet in existence that allows us to quickly and securely discriminate between genuine and professional counterfeit. At least some fundamental knowledge is required of the great variety of existing security features and common counterfeiting methods in order to be able to assess a questioned document. This course surveys a broad variety of security features, touching the basics of substrate, ink, print and foil based security. Classic security features as well as recent security developments are discussed. Extensive image material is presented and the relative security value of different features is assessed with the methods available to professional counterfeiters in mind.
Ruud van Renesse, based in The Netherlands, is an independent consultant in the field of document and product security for government departments, banking and financial institutions and industry. Van Renesse is the author of the textbook Optical Document Security, an internationally recognized textbook on all aspects of document security.
Who should attend?
This course will benefit everyone involved in the design, production and examination of valuable documents and products, whether management or technical personnel. A general understanding of basic optics, but no prior experience in document security, is required.
Short Course Notes
The course price includes the short course presentation on CD-ROM.
