1. An information processing method, applied to an electronic device comprising a processor and a displayer, wherein M applications are operating on the electronic device where M is a positive integer, each of the M applications has at least one interface currently displayed on the displayer of the electronic device, and the method comprising: detecting, by the processor, a first operation of a first application, wherein the first application is operating in a background of the electronic device, and the first operation is for displaying a first interface corresponding to the first application on the displayer of the electronic device; determining whether the first application is identical to one of the M applications; displaying, by the processor, the first interface corresponding to the first application on the displayer of the electronic device in response to the first operation after determining that the first application is identical to one of the M applications; generating, by the processor, and outputting a prompt message indicating that the first interface corresponding to the first application is about to be displayed in response to determining that the first application is not identical to any one of the M applications; and based upon a user input operation received in response to the prompt message, prohibiting, by the processor, display of the first interface corresponding to the first application on the displayer of the electronic device when the user input operation indicates that it is prohibited to respond to the first operation.
