Recognition method and device based on scrambled image, electronic equipment and medium

Abstract

The embodiment of the invention discloses a recognition method and device based on a scrambled face, electronic equipment and a medium. The method comprises the following steps: if a scrambling parameter acquisition request of a terminal for a target image is received, determining a target scrambling parameter which is not adopted by other terminals, wherein the target image is an image in the terminal; sending the target scrambling parameter to the terminal, so that the terminal performs slice transformation processing on the target image by adopting the target scrambling parameter to obtain a scrambled image; and receiving the scrambled image sent by the terminal for image recognition. According to the scheme, the problem that the image security is difficult to guarantee because scrambled images of other terminals can be cracked and restored due to the fact that the terminals have the same scrambling parameters is solved, and the security of the images in the terminals is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image processing, and in particular, to a recognition method, device, electronic device, and medium based on scrambled images. Background technique [0002] Face images are the data basis for public security management, but face data involves citizens' privacy, and once leaked, it may have a major impact on citizens' work and life. At present, the scheme adopted for face image security is generally to encrypt the face image using encryption algorithms such as symmetric encryption, asymmetric encryption, and MD5 (Message-Digest Algorithm, information digest algorithm) before the face image is transmitted. However, the encrypted face image cannot be used, and processing such as face recognition cannot be performed. If the face image is decrypted and used, there is still a risk of privacy leakage. [0003] For the security of face images, it is also possible to scramble the face...

Problems solved by technology

However, if multiple terminals use the same scrambling algorithm to scramble the face image, when the terminal obtains the scrambled face image of other terminals, it can scramble the scrambled face image according to the scrambling algorithm. Restore, there is a risk of privacy leakage
