Abstract: A computer-implemented method and a computing system are provided for training a matting neural network to generate mattes for creating portraits to be used on identity documents. The matting neural network is trained by using standardized images conforming to a template which prescribes that each standardized image should depict a human face. A standardized image is obtained by adjusting an input image which includes an area representing a face of the person and was, e.g., taken with a camera, so that a relationship between the size of the adjusted input image and the distance between target points (which represent parts of the person) in the adjusted input image satisfies a condition determined by the template, and in the adjusted input image the area is in a position defined by the template.

Abstract: An eUICC card comprising an initial runtime environment, subscriber profiles, associated adapters, and an adaptive routine configured to apply these adapters. An adapter enables the initial runtime environment to be adapted to the specificities of the corresponding profile when the latter is enabled. To enable dynamic adaptation of the runtime environment to the profiles used, the eUICC card further comprises inverse adapters associated with the profiles. The inverse adapter of the active profile makes it possible to restore the initial runtime environment upon disabling or deleting this profile. The adaptation can consist of modifying a Java class of the Java Card runtime environment of the eUICC, to the specificities of a profile.

Abstract: Methods, systems, and computer-readable storage media for verification of identity of individuals based on images obtained by two cameras. A first stream of images of an individual are obtained from a first camera. Gamma correction is applied to images of the first stream of images. A second stream of images of the individual is obtained simultaneously with the first stream of images from a second camera, where gamma correction is not applied to images of the second stream of images. An identity of the individual is verified by providing the first stream of images and the second stream of images for independent automated matching with an authentication image. The authentication image is an image of the individual from a verified source.

Abstract: The present invention relates to the management of the execution of resource-intensive operations within a secure element. The operation is formed of a plurality of elementary operations. In order to prevent the operation from monopolizing resources over a long period while high responsiveness of the secure element is sought, in particular in 5G-related technologies, provision is made, upon receipt of an APDU command from a host equipment, to trigger a time counter in order to determine an actual processing duration to process the APDU command. If this duration proves to be less than a predefined duration allocated to the APDU command, one or more of said elementary operations may be executed during the remaining time of said allocated duration. Upon expiry of this allocated duration, the secure element sends a response to the APDU command. The operation may thus be executed gradually without preventing the secure element from being highly responsive to received APDU commands.

Abstract: A method for personalizing embedded secure elements, eSE, allows for simplified manufacturing before being integrated into host devices. An eSE implements services executed by an embedded operating system, OS, whereupon it is loaded into the eSE. The non-personalized eSE comprises an OS loader and a master cryptographic key common to a plurality of secure elements. It can therefore be produced in large numbers. The OS loader obtains an operating system package from a server and installs it. In response to the installation, the OS loader generates a derivation cryptographic key by diversifying the master cryptographic key, and then the OS generates personalized data by deriving pre-personalization data with the derivation key. The eSE, deployed in the field in a simple non-personalized state, is fully personalized without exchanging secret personalized data.
