Abstract

Pour permettre la lecture de données depuis une mémoire d'un appareil mobile (2) à distance, par ex. un appareil mobile de véhicule, par l'intermédiaire d'un serveur (4), une liaison de communication sans fil est établie par le serveur (4), entre lui et l'appareil (2), une vérification d'authentification est ensuite effectuée sur le côté serveur, et une liaison VPN (virtuelle private Netzwerks- / réseau privée virtuelle) est établie depuis le côté du serveur (4), les données étant ensuite lues depuis la mémoire (3) de l'appareil (2), transmises au serveur (4) par la liaison VPN et enregistrées.
