Jura has developed different security features based on Information Carrier Digital Screening. Substance of such features is that a non-visible secondary image is encoded in a visible primary image. The encoded image will be visible only by using a decoding device.
One of such developments is JURA's Invisible Personal Information (IPI) is widely used in high security documents, where personal data of the document holder are encoded in the screen of the document holder's photography and they can be decoded by using an optical decoding device. In order to make document verification fully automated, enhance security and eliminate human factors, digital version of IPI, the D-IPI was developed. A special 2D-barcode structure was designed, which contains sufficient quantity of encoded digital information and can be embedded into the photo. Other part of Digital-IPI is the reading software, that is able to retrieve the encoded information with high reliability. The reading software developed with a specific 2D structure is providing the possibility of a forensic analysis. Such analysis will discover all kind of manipulations -- globally, if the photography was simply changed and selectively, if only part of the photography was manipulated. Digital IPI is a good example how benefits of digital technology can be exploited by using optical security and how technology for optical security can be converted into digital technology. The D-IPI process is compatible with all current personalization printers and materials (polycarbonate, PVC, security papers, Teslin-foils, etc.) and can provide any document with enhanced security and tamper-resistance.
Jura is an Austrian-Hungarian company providing security printers with proprietary security printing design software, complete security printing pre=press systems (HW + SW), ultrahigh resolution image setters developed for security printing market, security features, developed by Jura for security printing in general, proprietary security features, destined for document personalization systems. In addition to supply such products Jura is providing its customers with full technical support, as integration, installation, training, hot-line remote and/or on-site support, service and maintenance worldwide. Research and development have always been in the focus of Jura's activity. Development and testing of new software, new security features are the most important parts of the work. Jura was the first on the world to release her Engraver Software enabling artist-engravers to create engraving-styled portraits digitally. This development, incompatibility with Jura's security design software package, enabled a full digital workflow for banknote origination. Jura made a lot of remarkable steps to develop security features also for Document Personalization. This development links the personal data with the photography of the document' holder by encoding personal data to the photography, invisibly for naked human eye, however, decodable by an appropriate decoding device. This feature exists also in machine-readable digital version. Experts of Jura started the research and development on digital screening 15 years ago for commercial printing and 10 years ago on special screens for security printing technologies. In very early stage of this development, when knowledge of creating each screen-dot individually in shape, form and position was acquired, the idea was born to use the screen dots as secondary data holder for encoded messages.
