Abstract

Des informations de position, telles qu'elles sont mesurées par le terminal d'un corps mobile, sont codées et transmises à un centre d'enregistrement de positions qui mémorise les informations de position de chaque corps mobile à l'état codé. Soit le corps mobile, soit un centre de service d'informations de position destiné à fournir un service d'informations de position prédéterminé au corps mobile peut administrer les informations de position du corps mobile sans empiéter sur le caractère privé du corps mobile parce qu'il ne peut pas décoder les informations de positions d'une autre personne, telles qu'elles sont enregistrées dans le centre (dispositif) d'enregistrement de positions, sans la permission émise par une personne concernée. De plus, le centre (dispositif ) d'enregistrement de positions lui-même peut garantir une sécurité élevée parce qu'il ne peut pas décoder les informations de position mémorisées sans acquérir une clé de chiffrage auprès du corps mobile.
