High-security design software business Jura Group will show off its machine-verifiable secure ghost image service called LetterScreen++ at CARTES.

The service creates the secondary image on passport data pages by building up the portrait from lines of microtext. This enhances security by linking the photo of the passport to the document in machine-readable format.

LetterScreen++ uses microdata to cite the applicant’s name, document number and other relevant personal data via personalised text lines that fill the entire image. Slight differences in character size and thickness are used to build up an image of the document holder. The text lines are printed in unique waves created with a special algorithm based on personal data. The first-level verification of LetterScreen++ is based on a visual comparison of text in the LetterScreen++ and the readable personal data.

The software in the reader regenerates the wave structure and compares the regenerated waves with those read by the optics. The software issues a warning if the two are different. The two wave structures are also shown on the screen. LetterScreen++ can also be deployed as a security feature for use in forensic analysis.
