Abstract: A method and device for producing a target image having pixels (2) juxtaposed in a substrate (1) presenting thickness and producing an image presenting thickness such that each pixel (2) produces a shadowing effect on its neighboring pixels. The method includes: determining a production setpoint from the target image; and producing an image made by the device using the production setpoint. The determining operation replaces the production setpoint with an improved production setpoint that is determined by modeling the image production device using a transfer function for transforming a production setpoint into a predicted image; and determining an improved production setpoint in which the image produced by the transfer function is as close as possible to the target image, so as to reduce the consequences of the shadowing effect in the resulting image. Also included is the image produced by such a method.

Abstract: A method of managing profiles in a secure element where the secure element includes an active first profile associated with a first communication network and a second profile associated with a second communication network. The method includes deactivating the first profile and activating the second profile, where the deactivation and the activation are implemented following detection of a failure during a local verification pertaining to the first profile for the use of this the first profile. A local verification may be a verification in the secure element of the authorization of access of a user to the first profile, for example three failures of PIN or PUK code or of biometric authentication data, the local verification being performed in the secure element, and the failure being relative to a security failure of the first profile or to an operating failure of the first profile.

Abstract: Authentication device and method for a system that includes a subscriber device and a companion device. The authentication method includes the subscriber device delivering to the companion device a temporary profile and an authentication response signed by the subscriber device for sending to a server, installing the temporary profile to configure a second wireless communication interface of the companion device, and requesting a second authentication from the server via the second interface by using the delivered authentication response so as to authorize the second interface when the companion device and the subscriber device are not in communication with each other via the first communication interface. The device and method may be used by systems that include a subscriber device (e.g., a mobile telephone) and a companion device, e.g. a connected watch or object.

Abstract: A method and corresponding electronic device for securing the device. The device and method may include operations for: receiving a command requesting a modification of an operating parameter of the electronic device (C2); detecting whether the operating parameter is a parameter that is predefined as a sensitive parameter; and if so, determining whether the modification requested by the command, if applied, would lead to a degradation of the security of the electronic device. The determining may be done by comparing the initial state of the parameter on receiving the command with a new state for giving to the operating parameter in response to the command. And, in the event of the security of the electronic device being degraded, triggering an operation of securing the electronic device in response to the first command.
