Embodiment Construction

[0036] Embodiments of the present invention provide a method and device for occluding a specific position of an image, by positioning the first image, determining the position of the occluded image in the first image; performing image scrambling on the occluded image at the position processing to obtain the second image. A reversible image scrambling method is used to process the occluded image, so that when the original image information needs to be viewed, the original image can be completely restored for the staff to view, which is conducive to information query.

[0037] Preferably, the position information of the occlusion image of the image is embedded into the second image to obtain a third image, and the third image is transmitted, which avoids separately transmitting the position information of the occlusion image, and on the one hand improves Security, on the other hand, reduces the amount of data that needs to be transmitted or stored, and improves the utilization o...
