Abstract

L'invention porte sur un procédé et un système d'analyse de la corrélation entre utilisateurs par utilisation de données de format de fichier d'image échangeable (EXIF). Le procédé consiste à : déterminer un lieu de prise d'image d'une image, prise par un téléphone intelligent, par utilisation de la technologie du système mondial de localisation (GPS) lorsque l'image est prise, et géo-marquer des données EXIF de l'image, comprenant une heure (ou date) de prise d'image de l'image, avec le lieu de prise d'image déterminé ; autoriser en premier lieu le téléphone intelligent à envoyer les données EXIF géo-marquées à un serveur conjointement avec des informations d'utilisateur du téléphone intelligent ; et autoriser en second lieu le serveur à rechercher et trouver des informations d'utilisateur de téléphone intelligent corrélé, qui sont des informations sur n'importe quel utilisateur de téléphone intelligent corrélé à un utilisateur du téléphone intelligent en termes de l'heure (ou date) et du lieu de prise d'image de l'image, dans une base de données EXIF, qui stocke au moins une donnée EXIF, comprenant des informations d'heure (ou date) de prise d'image et des informations de lieu de prise d'image, pour chaque information d'utilisateur de téléphone intelligent, par utilisation de l'heure (ou date) et du lieu de prise d'image de l'image, et à envoyer les informations d'utilisateur de téléphone intelligent corrélé trouvées au téléphone intelligent.
