Abstract: Disclosed is a method for loading, by a manager, a profile into a memory of a secure element, SE. A profile allows the SE to identify itself to a service. The profile includes a profile element created by reference to a template. A template is identified by an OID identifier, which it keeps despite changes. The manager may transmit an audit request or update the operating system of the SE in order to obtain, in response, a piece of information representative of the version of the template stored by the SE. The manager then identifies any difference in version with the corresponding template it holds. In case of difference, the template of the SE or the template of the manager is updated so as to align their versions. Thus, a profile generated on the basis of this version of the template will be loaded, without malfunction, by the SE.

Abstract: A method for digital signing of a document using a predetermined secret key. An initial internal state is determined by application to a condensate of the document of a first white box implementation of generation of a main nonce; then a modular sum of the main nonce and of a predetermined constant. The method also determines a first internal state by application to the initial internal state of a first modular arithmetic operation, then of a modular product with exponentiation of the predetermined constant. The method then determines a second internal state by application to said condensate of a second white box implementation of generation of the main nonce; and a second modular arithmetic operation function of the first internal state, of the main signature nonce and of the secret key. It then generates a digital signature of the document from the first internal state and the second internal state.

Abstract: A facial recognition method is disclosed that is executed by a system comprising an image capture device and a light source able to illuminate a face positioned in front of the device. A plurality of images of a face is acquired, the light source producing a different illumination of the face at each image acquisition, and values representing the face from the plurality of images are extracted. To this aim, a first image of a face is acquired. An SNR value, referred to as the estimated value, of the first image is estimated from a reference SNR value, from image acquisition parameters and from values representing distances between the face and said device. Finally, the estimated value is used in order to determine whether or not the recognition procedure should be executed.

The dynamic window includes an optically variable coating on at least a front or a back of the dynamic window.

Fabricating an identification document with a dynamic window includes forming an opening in a core layer, positioning a dynamic window in the opening, and plate laminating the core layer and the dynamic window between at least one outer layer on each side of the core layer.

Abstract: Disclosed is management of a plurality of active subscriber profiles at the same time within the same secure element integrated in a host terminal. A baseband processor of the terminal and a communication interface controller of the secure element together establish different separate links for each one of the active profiles. It is thus possible to address, and therefore to simultaneously use, a plurality of profiles. A link can be the conventional ISO 7816 link. The HCI/SWP interface allows a large number of logical links (or HCI pipes) to be established using a single additional tab for connecting the secure element in the terminal. Each active profile is thus associated with an HCI pipe for routing messages relating thereto. As a variant or in combination, an SPI interface allows master-slave logical links to be established.

Abstract: To ensure the quality of NFC communication between a contactless card and a smartphone, a positioning pattern, for example a portion of the card visual, is displayed on the screen of the smartphone. This is a visual aid to help the user to position the contactless card, in proximity to the smartphone, toward a position where a card indicator for which provision is made on the card, typically the portion complementary to the card visual, is aligned with the displayed pattern. The positioning is made easy as the positioning pattern and the card indicator are preferably chosen to be visually complementary. Also, the contactless card is in the appropriate position when the card indicator visually complements the positioning pattern. The positioning pattern is thus displayed at a location of the screen allowing the best NFC coupling between the card and the smartphone.
