Abstract: Embodiments of the present disclosure relate to a method. The method comprises, at a first user device, receiving user data from a tamper-proof second user device. Further, the method comprises, at the first user device, aggregating the user data according to a first logic and transmitting the aggregated user data and the user data to an external server. The method further comprises, at the external server, verifying whether the first logic, by which the aggregated user data and the user data are related to each other, corresponds to a predefined second logic for verifying a validity of the aggregated user data.

Abstract: Provided is an anti-counterfeit label with multi-focus multi-layer depth-of-field images. The anti-counterfeit label is sequentially provided with a multi-focus microlens array layer, a transparent base membrane layer and a microtext array layer from top to bottom in a laminating mode, and a metal reflective layer is arranged under the microtext array layer; the multi-focus microlens array layer comprises microlenses which are distributed in an array mode and have multiple focuses; the microtext array layer comprises one set or multiple sets of subunit pattern periodic ordered arrays. The anti-counterfeit label has the advantages that the microtext array layer can be amplified by 80-800 times by the multi-focus microlens array layer. The anti-counterfeit label is particularly suitable for popular anti-counterfeiting and can effectively improve the anti-counterfeit capacity.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a data carrier having a see-through portion (24) that allows revealing security features (36) with a different appearance on each of its sides (S1, S2) 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.

Abstract: 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 ?i of pixels defined in the identification image, said pixels of the matrix ?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(?i) and the texture level T(?i) of said matrix ?i.

Abstract: 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.
