A security device (100) comprises at least one magnetic element (102). The magnetic element (102) is responsive to an applied magnetic field to provide a characteristic response. The characteristic response can be used to identify a particular security device (100) when interrogated by a security system, thereby aiding in prevention of copying of the security device (100).

Cette invention concerne un système de sécurité (100) comprenant au moins un élément magnétique (102). En cas d'application d'un champ magnétique, l'élément magnétique (102) réagit en fournissant une réponse caractéristique. Cette réponse caractéristique peut s'utiliser pour identifier un dispositif de sécurité particulier (100) en cas d'interrogation par un système de sécurité, ce qui contribue à empêcher que le dispositif de sécurité (100) ne soit copié.
