5. The concealment method according to claim 3, wherein the requirement type is updating a watermark layer, and the step of determining the target image comprises:
determining an updated display area based on the updated number and/or the updated attribute of the display;
and drawing the watermark image layer to the updated display area to generate the target image.
6. The concealment method according to claim 3, wherein the requirement type is updating a watermark layer, and the step of determining the target image further comprises:
acquiring updated identification information of the target terminal;
determining the updated watermark of the target terminal according to the updated identification information of the target terminal and the mapping relation between the preset identification information and the watermark;
determining an updated watermark layer according to the updated watermark mark;
and drawing the updated watermark layer in the display area to generate a target image.
7. A watermark hiding apparatus, characterized in that the hiding apparatus comprises:
the judging module is used for determining the display area of the watermark according to the number of the displays of the target terminal and the display attribute;

a display module for imaging the target image on the display.
8. The concealment apparatus according to claim 7, wherein the concealment apparatus further comprises a generation module, and when configured to generate the watermark layer, the generation module is specifically configured to:
determining the watermark of the target terminal according to the identification information of the target terminal and the mapping relation between the preset identification information and the watermark;
converting the watermark into a target character string in a preset form, and encoding the target character string;
converting the coded target character string to obtain an atom layer corresponding to the target character string;
and generating the watermark layer according to the atomic layer.
9. An electronic device, comprising: a processor, a memory and a bus, the memory storing machine-readable instructions executable by the processor, the processor and the memory communicating via the bus when an electronic device is running, the machine-readable instructions being executed by the processor to perform the steps of the method of hiding a watermark according to any one of claims 1 to 6.
10. A computer-readable storage medium, characterized in that the computer-readable storage medium has stored thereon a computer program which, when being executed by a processor, performs the steps of the method of hiding a watermark according to any one of claims 1 to 6.
