Abstract

L'invention concerne un procédé de traitement d'informations et un dispositif associé. Le procédé comprend les étapes suivantes : un nœud de commerçant envoie une demande d'extraction d'informations d'utilisateur à un nœud d'utilisateur, la demande d'extraction d'informations d'utilisateur transportant une clé publique de commerçant, et étant utilisée pour ordonner au nœud d'utilisateur d'acquérir des informations d'utilisateur à chiffrer et d'utiliser la clé publique de commerçant pour chiffrer les informations d'utilisateur afin d'obtenir des informations d'utilisateur chiffrées ; le nœud de commerçant reçoit une réponse d'extraction d'informations d'utilisateur envoyée par le nœud d'utilisateur, la réponse d'extraction d'informations d'utilisateur transportant les informations d'utilisateur chiffrées ; le nœud de commerçant utilise une clé privée de commerçant pour déchiffrer les informations d'utilisateur chiffrées de façon à obtenir des informations d'utilisateur non chiffrées, la clé privée de commerçant correspondant à la clé publique de commerçant ; et le nœud de commerçant génère une carte de membre électronique sur la base des informations d'utilisateur non chiffrées. Le procédé améliore la précision des informations.
