Problems solved by technology

When the screen content of the user is photographed by others on the screen of the terminal device, or the real-time display of the screen is obtained by a malicious application on the terminal, many private data of the user are leaked through the screen image
[0003] In related technologies, for the encryption of terminal images, some keys encrypt images, which has low security, and these encryption methods are often easily cracked by artificial intelligence technology
Some strengthen the security of the image by setting a different key for each image, but the workload is heavy, which brings a greater burden on the calculation and storage of the system

Abstract

The embodiment of the invention provides an image encryption method and device, electronic equipment and a readable storage medium, and belongs to the technical field of image processing. The image encryption method comprises the following steps: determining a target area where to-be-encrypted content in a to-be-encrypted original image is located; performing mask processing on the target area, and determining mask information of the target area; adding adversarial noise and auxiliary noise to the original image, and generating a noise image; and performing fusion processing on the original image, the noise image and the mask information to generate a target encrypted image.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular, to an image encryption method, device, electronic equipment and readable storage medium. Background technique [0002] With the continuous development of mobile Internet terminal equipment, more and more information exchange depends on the transmission of terminal equipment. When the screen content of the user is captured by others on the screen of the terminal device, or the real-time display of the screen is obtained by a malicious application on the terminal, many private data of the user will be leaked through the screen image. [0003] In related technologies, for the encryption of terminal images, some keys are used to encrypt images, which has low security, and these encryption methods are often easily cracked by artificial intelligence technology. Some strengthen the security of the image by setting a different key for each image, but the workload is hea...
