SECURE DOCUMENT, IN PARTICULAR ELECTRONIC PASSPORT WITH ENHANCED SECURITY

摘要

The invention relates to a secure document (13), in particular an electronic passport, comprising a support provided on the one hand with active security means (3) comprising a microcircuit linked to an antenna (5) capable of producing an electromagnetic response when it passes through the electromagnetic field of a contactless reader designed to interrogate the identity document (13). The identity document is characterized in that said support is provided on the other hand with passive security means (11, 15) chosen in such a way as to exhibit electrical characteristics, in particular inductive, capacitive and resistive (R, L, C) characteristics suitable for amplifying the electromagnetic response of the active security means (3) so as to take it beyond a threshold allowing the identification of the secure document (13), when the latter is placed in the electromagnetic field of a contactless reader. The invention finds its application in particular in national programmes for issuing passports with enhanced security.
