Abstract

La présente demande concerne un procédé et un appareil de duplication d'écran, ainsi qu'un dispositif électronique et un support de stockage. Le procédé de duplication d'écran consiste à : mettre en pause la transmission d'un signal de duplication d'écran lorsqu'il est détecté qu'une application de couche supérieure bascule d'une première application cible à une seconde application cible pendant un processus de duplication d'écran ; acquérir une liste blanche de duplication d'écran, et déterminer, selon la liste blanche de duplication d'écran, si la seconde application cible est une application sur liste blanche ; et s'il est déterminé que la seconde application cible est une application sur liste blanche, continuer à transmettre le signal de duplication d'écran. La présente invention résout le problème technique de la divulgation de confidentialité pendant un processus de duplication d'écran dans l'état de la technique.
