Abstract

Des modes de réalisation de la présente invention concernent le domaine technique des terminaux. L'invention concerne un procédé de gestion de processus d'arrière-plan et un dispositif terminal. Le procédé comprend les étapes suivantes : un dispositif terminal sélectionne un processus d'arrière-plan cible à partir de processus d'arrière-plan en cours d'exécution, le processus d'arrière-plan cible étant un processus d'arrière-plan non nécessaire ou malveillant; le dispositif terminal permet au processus d'arrière-plan cible de s'arrêter; et le dispositif terminal envoie une instruction de gel au processus d'arrière-plan cible, de telle sorte que le processus d'arrière-plan cible est fermé et ne peut pas être démarré. En mettant en oeuvre les modes de réalisation de la présente invention, des processus d'arrière-plan inutiles et malveillants dans un dispositif terminal peuvent être gelés, de sorte que le stockage interne, la quantité électrique et le flux de données du dispositif terminal sont sauvegardés, et les informations personnelles et les données privées d'un utilisateur ne peuvent pas être volées.
