Implementation of Security Features

Our machines enable our customers to implement a wide range of document security features. We use the laboratories at our premises for designing security features as well as for testing their applicability in the mass production. Some security features have been invented and designed by our company. Others are the ideas or Intellectual Property of our customers, who have recognised our company for being a competent partner for their implementation.

We place great emphasis on obtaining the most optimal parameters for the implementation of security features. We analyse the obtained results with our clients and jointly work on further improvements in order to make the final product unique.

While developing solutions, we pay particular attention to ensuring that the quality and precision achieved in the laboratory is repeatable and consistent. In high-volume production, our machines provide long term personalisation process stability, continuously producing the same high quality results.

LASINK™ HELIOS

Our machines implement document security techniques developed by IDEMIA

Color Photo LASINK™ HELIOS

LASINK™ Helios, a color portrait in a DOVID to secure identity documents

IDEMIA continuously innovates to create high-tech security features that are hard to reproduce yet easy to inspect. LASINK™ Helios is a full color secondary portrait within a DOVID. It is based on two proven technologies in the ID security market: IDEMIA’s LASINK™ color portrait and diffractive optical technology. The cutting-edge DOVID optical effects of LASINK™ Helios have been designed to prevent multiple types of ID theft and fraud and ease authentication. Video published by IDEMIA, Nov 25, 2021.

Color portraits on polycarbonate ID documents

With LASINK™ Origin, the color portrait of the document’s holder is engraved directly into the polycarbonate structure by a laser during the personalization stage.

LASINK™ Origin color photos have a unique linear pattern that acts as a signature to authenticate thedocument.

Its recognizable design cannot be imitated with any digital printing technology or forged as the picture is located within the substrate and not on the surface. The ID document cannot be delaminated without leaving a trace.

The personalization technique is kept secret and prevents the use of stolen blank documents, as they cannot be properly personalized without the use of the dedicated software.

LASINK™ Origin gives flexibility to governments: it can either be used in centralized or decentralized personalization solutions.

LASINK™ Origin is very robust and offers a ten-year lifespan.

GHBM

The figure shows how the hidden information in the photo is read

GHBM – Hidden image detected in transmitted or reflected light

Hidden image detected in transmitted or reflected light

The photo with the hidden information is engraved using a high resolution laser on a transparent window. To read the hidden information, only a point source of light is needed. The light should pass from the back of the document through the transparent window with the engraved photo. A flashlight on a smartphone can be used as a light source. Without a punctual light source, the hidden text is completely invisible and the photo is not disturbed. The photo is high quality and contains details allowing for unambiguous recognition of the person. This security feature was implemented jointly and then patented by the following companies: UAB Garsų Pasaulis, Polish Holographic Systems and BAUER + MÜCK GmbH (GHBM).

Transparent Phantom Photo

The Phantom Photo is a transparent photo, laser-engraved on the surface, made visible by the reflection of light at a certain angle.

Optionally, a transparent photo can be associated with a grayscale photo, as shown in our example.

Phantom Photo is visible when the document is tilted, so that incident light is reflected by the surface of the document. The grayscale image is not visible in this position. On the smooth surface of the document both types of images can be seen transparently contrasting (as positive):

  • contours of the face: a black-and-white image
  • area of the face: a grayscale image.

Other security features

Recto-Verso, Laser Perforation, Photo 3D, CLI/MLI/SLI®, Steganography, Micro and Nano text etc.
Recto-Verso

Certain fragments of an image are embedded in the front of the document by means of an imprint. The imprint is completed with using laser engraving on the back side. Due to the fact that the document area is semi-transparent at the RECTO-VERSO element, the entire shape is visible as a result of the combination of both techniques as well as both techniques‘ fragments are visible on front and back side respectively. The precise alignment of the positions of the two fragments of images plays a key role.

Laser Perforation

Using the laser, micro-holes are created in the material. This allows to create a specific presentation of a photo. By using a light source, the person’s face is visible and the precision of the details makes it possible to recognize the person. This technique allows to achieve particularly high quality reproduction on paper.

Photo 3D

The Photo 3D effect is implemented on appropriately prepared lenses integrated in a personalized document. Specially prepared photos of a person are engraved by the laser in the area of those lenses. Each of the photos presents the person’s face seen from a different angle. Ultimately, the three-dimensional effect is obtained by interpolating the images in the human’s brain.

Micro and Nano text

Texts that require a magnifying glass or microscope to read can be engraved using our Laser personalisation. The example above is a photo of a document taken with a microscope. The size of the engraved text in this example is from 37 µm up to 75 µm. Even with the smallest font size it is possible to read the text using a microscope.

KINEGRAM ZERO.ZERO

High precision laser systems allow perfectly integrate laser personalisation techniques with the KINEGRAM ZERO.ZERO placed in the area of the main photo. The kinegram is mapped by a vision system and exactly excluded from engraving.

KINEGRAM ZERO.ZERO was developed by OVD Kinegram – The unique metallization solution for high security and visual attractiveness.

Dithering

Dithering is an image processing operation used to create an impression of a photo of full grayscale depth using a laser process with limited grayscale values. The use of the Dithering algorithm combined with high resolution laser engraving results in a very good quality photo. The application of this technique is an interesting solution for an additional photo. Using a magnifying glass, you can identify the characteristics of the Dithering algorithm.

IPI™

Invisible Personal Information (IPI™) and LetterScreen® are technologies developed by JURA.

IPI™ and LetterScreen++® technologies encode personal data in the primary portrait, protecting both the portrait and the data against tampering/manipulation and unauthorized personalisation.

Outline Fonts

The algorithm for creating texts with outline fonts, providing the ability to individually set the grayscale value for the outline and fill of a character. The picture above shows examples of figures using the outline text algorithm. The characters are 1.8 mm high.
