Embodiment Construction

[0029] The solutions provided in this specification will be described below in conjunction with the accompanying drawings.

[0030] First, combine figure 1 A specific implementation scenario is shown for description. figure 1 The implementation scenario shown is an image recognition scenario in the face-swiping payment process. figure 1 It shows the face image recognition process of facial recognition payment in a specific implementation scenario. figure 1 The face image recognition process is divided into two parts, the image acquisition part of the terminal platform, and the image recognition part of the server platform. These two parts need to be connected through the data network transmission between the terminal and the server.

[0031] On the terminal platform, the smart terminal can collect face images through an image collection device (such as a camera). Afterwards, color features are collected for the face image. Different color coding methods correspond to diff...

Abstract

The embodiment of the specification provides an image processing method for realizing privacy protection. A private image is subjected to desensitization and compression processing at a terminal; andimage recognition is carried out at a server side according to the desensitized and compressed data. Frequency domain features of the private image are extracted through the terminal; preprocessing and screening are carried out on the frequency domain feature map, and the feature map more beneficial to image recognition is obtained in a self-adaptive mode. Compared with pure image compression, the provided method has the advantages: the compression rate in the image transmission process is improved, data privacy is effectively protected, the data processing amount is reduced, so that the effectiveness of image processing is improved.

Description

technical field [0001] One or more embodiments of this specification relate to the field of computer technology, and in particular, to an image processing method and device for realizing privacy protection. Background technique [0002] With the development of computer technology, image recognition has penetrated more and more into various fields of people's lives. For example, unmanned driving, intelligent unlocking based on face or fingerprint recognition, terminal application login, etc. In some cases, image recognition can be local image recognition, such as smart unlocking, which can control unlocking through several face images / fingerprint images stored locally on smart terminals or smart locks. In other cases, the terminal cannot store relevant images in advance, or the computing power of the terminal is insufficient to complete image recognition, such as logging in to web applications that require face recognition through public computers, smart cash registers with ...
