Paper Abstract

Traditional security systems are becoming more and more useless as the digital technology moves on. Digital Graphical Systems and their increasing technology are now seriously forcing the security printing industry to start thinking 'digital'. Terms like digital signal and image processing, trail tracing, spread spectrum and digital watermarking, etc. are steadily moving into the security printers vocabulary. Digital technology should not only be seen as a threat but merely as an opportunity for security printers. This same technology can be used for a better implementation and integration of not just the tradition non-variable security feature but especially variable security features into security documents. Depending on the field of application these digital security features can be integrated into a design using localized spectrum, spread spectrum or full spectrum technology. In this presentation some applications will be explained and it will be shown how these technologies can be used to provide Security Solutions for the next Millennium.
