The invention relates to a secured document in the form of a booklet of at least one sheet which may be folded about a folding axis, the document having a transponder with an electronic chip provided with a memory for storing data and a transponder antenna. The document also includes a foldable amplifier antenna, distinct from the transponder antenna and arranged on the document such that, when the same is open, the amplifier antenna amplifies the electromagnetic flux received by the transponder antenna to permit communication of the document with a remote reader and, in the closed position of the document, the amplifier antenna reduces the electromagnetic flux received by the transponder antenna beneath a minimum threshold permitting communication of the electronic chip with a remote reader.

Embodiments of the invention provide a method of generating a UI visual presentation attribute scheme while preserving visual consistency of selected visual presentation attributes in the color scheme is provided. The method includes establishing a hierarchy of UI elements in a directed acyclic graph of nodes. The method yet further includes computing a visual presentation attribute for each child node of the hierarchy descending from a selected parent node according to an established transformation rule. Finally, the method includes exporting the hierarchy into a visual presentation attribute scheme. To the extent the visual presentation attribute is a color, the visual presentation attribute scheme can be a color scheme applicable to an application to define the color scheme of the application.

摘要:
A secure document, in particular an electronic passport, includes a support equipped, on the one hand, with active security devices having a microcircuit connected to an antenna that can produce an electromagnetic response when it passes through the electromagnetic field of a contactless reader designed to query the identity document. The support is equipped, on the other hand, with passive security devices selected so as to have electrical characteristics, in particular inductive, capacitive and resistive, that are suitable for amplifying the electromagnetic response of the active security devices to make it go beyond a threshold that allows the secure document to be identified when it is placed in the electromagnetic field of a contactless reader. The invention has a useful application in national programs to issue passports with increased security.
