The present invention relates generally a method to authenticate a data carrier, such as passports, licenses, identification card . . . by hiding at least two optically encoded image within a data carrier so that the data carrier is authenticated through at least two factor authentication process. In the methods of the present invention, at least two reliable, readable optically encoded image are hidden within the data carrier wherein each of the encoded image is visible through a same decoder device but under different specific lighting conditions without the former having influence on the quality of the latter. The authentication methodology of the present invention provides an improved security, being even more difficult to reproduce by infringers, even more difficult to remove, replace or exchange and easy to check.

Data carrier and a method for producing such data carrier

Security article and method for producing a security article. The method includes microprinting on a patch an array of microimages, placing a first translucent layer over the substrate and first patch, and laminating the substrate, the patch, and the first translucent layer using a lamination tool. The resulting security product includes a microlens array is located in the first translucent layer in register with the patch such that microimages have a one-to-one correspondence with lenses of the array of microlenses, wherein when the microimage array is viewed by a viewer through the microlens array, a composite image is visible to a viewer of the security article.

Integrated floating image for security documents

The present invention relates generally to a data carrier comprising an opaque layer and a method for making the data carrier. During personalization phase, the ablation of the opaque layer by laser through the data carrier allows to define a see-through portion of the data carrier carrying opaque security, said see-through portion having an improved security corresponding to opaque embossing pattern overlapping at least partially the opaque security partially destroyed. Said defined see-through portion carrying opaque security partially destroyed with opaque embossing pattern on its surface is even more difficult to reproduce by forger, even more difficult to remove, replace or exchange and easy to check.

Method for producing a data carrier and data carrier produced therefrom

The present invention relates to a data carrier, especially a security document, such as an identification card, e.g. a passport or a driving license, a credit card and a bank card, the data carrier comprising authentication data comprising personalized data, and as a security feature, an array of lenticular elements being arranged to provide only from predetermined angles of view an image of at least a piece of authentication data of said authentication data. In or to make the data carrier impossible or at least very difficult to copy and forge, the array of lenticular elements is provided with a complex structure providing a further security feature.

Data carrier

The invention relates to a data carrier having a see-through portion () that allows revealing security features () with a different appearance on each of its sides (S, S) under special lighting conditions, and a method for making such a data carrier. The see-through portion has an improved security, which is more difficult to reproduce by infringers.

Data carrier with see-through window and method for producing it

The invention relates to an identification document () comprising a non-transparent core (), and one or more layers of a transparent material () arranged on at least a back () or a front surface () of said core. In order to achieve an identification document where forgery attempts are visibly detectable, the identification document () has a translucent security element in a region () where the thickness of the non-transparent core () material is smaller as compared to the thickness of the non-transparent core material in other parts of said core ().

Identification document and a method of producing

The invention relates to an enhanced security feature for identification document. For that, the identification document comprises at least two constitution layers, a first specific coating () inside the document, between two constitution layers, said coating being able to be revealed under predetermined lighting conditions. It comprises also an assembly of micro-holes () provided through at least one of the layers, in order to make possible the revelation of the first specific coating under said predetermined conditions, said assembly of micro-holes, together with said coating to be revealed through micro-holes, drawing said security pattern.

Identification document comprising a security pattern

A data carrier is provided having a see-through portion () that allows revealing security features () with a different appearance on each of its sides (S, S) under special lighting conditions, and a method for making such a data carrier. The see-through portion has an improved security, which is more difficult to reproduce by infringers.

An information page () of a security document, includes: an information part (), on the upper or lower surface of which part of the information recorded on the information page () can be seen; and a flexible connecting part () with good bending strength for attaching the information page () to a security document. To ensure that detaching the information part and the connecting part from each other leaves visible marks, the connecting part () has a netlike structure, and the connecting part () is arranged to penetrate into the information part () in the immediate vicinity of the upper or lower surface of the information part.

Information page

The invention relates to a method for securing a first image by means of graphical anti-counterfeiting means and to a method for securing an identification document with such graphical anti-counterfeiting means. The invention also relates to a secure identification document that allows detecting either a fraudulent modification of the existing personalization or a fraudulent falsified document. For that, graphical anti-counterfeiting image is inserted into an identification image, each image being defined by a plurality of pixels. The characteristic level (for example grey level) of each pixel i of the graphical anti-counterfeiting image is linked, by a function F, to a matrix &#x3a9;i of pixels defined in the identification image, said pixels of the matrix &#x3a9;i surrounding the location i of a pixel of the graphical anti-counterfeiting image, said function F taking into account the characteristic level (for example average grey level) G(&#x3a9;i) and the texture level T(&#x3a9;i) of said matrix &#x3a9;i.

Method for securing an image by means of graphical anti-counterfeiting means, method for securing an identification document, and secure identification document

Guilloches (preventing modification) and watermarking (preventing substitution) technologies are combined to protect a medium, such as a card or a passport. The major idea stems from their dual role for medium authentication: the presence of one is needed to check the validity of the other one. By nature, the guilloche network is visible in the image and easily detectable by image processing. This network is therefore used to generate reference points as elements of synchronization to retrieve watermark information originally embedded in the medium that has submitted an RST transformation. These reference points are by nature stronger than any other means involving invisible templates in the spatial or Fourier space.
