Problems solved by technology
The encrypted image obtained in this way is often less secure, and it is easy to be cracked to obtain the information in the encrypted image, or the information in the encrypted image may be modified
Especially in application scenarios that require high image security such as facial recognition payment, this encryption method often cannot guarantee the security of facial recognition images, and then leaks user identity information used for payment verification in facial recognition images, threatening The user's information security reduces the security and confidentiality of image information

The embodiment of the invention provides an image encryption method and device, a computer readable medium and electronic equipment. The image encryption method comprises the following steps: generating a corresponding derivative image based on an acquired to-be-processed image, determining a first security factor based on a correlation degree between the derivative image and the to-be-processed image, and jointly generating an image security factor based on a second security factor generated based on the first security factor and an encryption parameter of the to-be-processed image; and encrypting the to-be-processed image based on the image security factor to generate encryption information corresponding to the to-be-processed image. In the embodiment, the information of the to-be-processed image is more difficult to crack and tamper in the transmission process, so that the security and confidentiality of the to-be-processed image are improved.
Description
technical field [0001] The present application relates to the field of computer technology, in particular, to an image encryption method, device, computer-readable medium and electronic equipment. Background technique [0002] In many image processing processes, images need to be encrypted to ensure the security and confidentiality of image information. In the related technologies, encryption is performed through an existing public encryption method to obtain an encrypted image, and then the encrypted image is transmitted or verified, and the like. The encrypted image obtained in this way is often of low security, and is easy to be cracked to obtain the information in the encrypted image, or may be modified. Especially in application scenarios that require high image security such as facial recognition payment, this encryption method often cannot guarantee the security of facial recognition images, and then leaks user identity information used for payment verification in fa...
