Abstract

La présente invention se rapporte à un procédé et à un système basés sur un motif de code à barres à deux dimensions. Le procédé et le système selon l'invention sont adaptés pour partager des données de réseau Wifi. Dans le procédé selon l'invention, un dispositif de transmission de données de réseau Wifi : accède à un réseau Wifi ; acquiert des données de point d'accès du réseau Wifi auquel il a accédé ; et convertit les données de point d'accès de sorte à obtenir un motif de code à barres à deux dimensions. Dans le procédé selon l'invention, d'autre part, un dispositif de réception de données de réseau Wifi : acquiert le motif de code à barres à deux dimensions ; résout le motif de code à barres à deux dimensions de sorte à acquérir les données de point d'accès ; et se connecte au réseau Wifi sur la base des données de point d'accès. En partageant les données de réseau Wifi via le motif de code à barres à deux dimensions, la présente invention augmente l'efficacité de partage des données de réseau Wifi. Par ailleurs, même si le motif de code à barres à deux dimensions était vu par un autre utilisateur, ce dernier ne pourrait pas acquérir des données telles que le type du réseau de points d'accès et le mot de passe. Par voie de conséquence, la présente invention améliore également et de façon significative la sécurité d'accès au réseau Wifi.
