Problems solved by technology

[0004] However, both of the above two technologies directly process the pixel values ​​in the face image, which may cause a large gap between the processed face image and the original face image, or the processed face image is abnormal, thus Reduced the visual friendliness of face images after privacy processing

Embodiment Construction

[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0034] In order to prevent malicious behaviors such as unauthorized use, face reproduction, counterfeiting, and stealing of face images stored in the cloud or published by attackers, pixelation technology or fuzzification technology is currently used to protect the personal privacy contained in face images. . Although these two technologies can prevent people or devices from identifying the private content in the original face image, and pla...

Abstract

The invention relates to the technical field of image privacy protection, and provides a method for protecting the privacy of a human face image and electronic equipment, and the method comprises the steps: carrying out the formatted representation of an original human face image, obtaining an original image matrix of pixel points of at least one human face position needing privacy processing, and carrying out the privacy processing through employing a trained human face generation model, the difference noise matrix can keep the distribution of the visual generation matrix of the key part consistent with the distribution of the original image matrix, so that the privacy of the original image matrix is perturbed, and the privacy of the original image matrix is perturbed. After the face local image generated by the vision generation matrix of the key part is used for replacing the corresponding key part in the original face image, it can be ensured that the obtained target face image is a normal face image, that is, good vision is kept; moreover, the target face image is tested, so that the usability of the target face image is ensured, and the personal privacy of the user is also protected.

Description

technical field [0001] The present application relates to the technical field of image privacy protection, and in particular, to a method and electronic device for protecting the privacy of a face image. Background technique [0002] With the development of artificial intelligence technology, some smart applications have functions such as face image recognition and face image release, which means that with the user's permission, their face images will be sent to third parties for cloud storage or publish. Malicious behaviors such as the leakage of cloud storage and the release of P-pictures of images will undoubtedly violate the personal privacy of users. [0003] At present, the methods to prevent the leakage of personal privacy in face images mainly include pixelation technology and blurring technology. Among them, the pixelization technology divides the face image into grid units, and sets all pixels in each unit to the common pixel intensity to reduce the personal info...
