摘要

The proposed technique relates to a method of managing a display of an application view (AppC) executed on an insecure processor (PNS) of an electronic data entry device, which further comprises a processor secured. The application (AppC) delivers at least one current view (VC), comprising a set of pixels, to be displayed on a screen of said device. This method, implemented under the control of the secure processor, comprises: an analysis step (AN) of the current view (VC), delivering at least one datum representative of a presence of at least one suspicious pattern; when a presence of at least one suspicious pattern is detected within the current view (VC), a step of implementation (PT), by the secure processor, of at least one protection measure.
