[0077] Please refer to Figure 2 , Figure 2 For an embodiment of the present application, if the set elements of the monitoring information are monitored, the anti-photographing mode is automatically triggered, the area for displaying the watermark information is determined according to the position and area of the elements, and the display of the watermark information is started in real time, and then the steps include:

[0078] S1041: display information including IP address, product batch number, login user, positioning data, etc.; and,

[0079] S1043: display content containing watermark plaintext display; and,

[0080] S1045: display information that needs to be decrypted to display in plaintext; and / or,

[0081] S1047: convert the watermark display content into a two-dimensional code picture as a watermark display to the Micro LED display screen, and detailed information can be read by scanning the two-dimensional code.

[0082] In some optional embodiments, please refer to Figure 3 , Figure 3 For an embodiment of the present application, if the set elements of the monitoring information are monitored, the anti-photographing mode is automatically triggered, the area for displaying the watermark information is determined according to the position and area of the elements, and the display of the watermark information is started in real time, and then the steps include:

[0083] S1061: encode the display content, the Micro LED display screen or its module, the display time, the display place, and the photographing area;

[0084] S1063: form a photographing area by surrounding the positioning data;

[0085] S1065: First mutual matching data of the encoded display content, the Micro LED display screen, the display time, the display place, and the photographing area are performed.

[0086] S1067: The in-place personnel in the photographing area are respectively secondly mutually matched with the first mutual matching data through face recognition on the place pictures in the photographing area, and the in-place time length ranking of the in-place personnel in the photographing area and the appearance frequency ranking of the in-place personnel in the photographing area are obtained.

[0087] S1069: Artificial fine screening is performed according to the in-place time length ranking of the in-place personnel in the photographing area and the appearance frequency ranking of the in-place personnel in the photographing area, and a photographing suspect is obtained.

[0088] For example, when a meeting is in progress and the meeting place pictures have been leaked, the in-place time length ranking and the appearance frequency ranking are helpful to quickly lock the photographing suspect and timely discover and stop the continuous occurrence of the leakage event.

[0089] For example, when a meeting has ended and it is found that the meeting place pictures have been leaked, the in-place time length ranking and the appearance frequency ranking are helpful to quickly lock the photographing suspect and quickly and accurately extract effective evidence.
