Abstract

The embodiment of the invention discloses an image processing method and device based on privacy protection and electronic equipment. The method comprises the following steps: acquiring a depth imageand a color image, wherein the depth image and the color image comprise privacy information of the same object; decomposing the depth image to obtain low-frequency information of the depth image; decomposing the color image to obtain high-frequency information of the color image; and generating a desensitized image after the privacy information is protected according to the low-frequency information and the high-frequency information. According to the image processing method and device and the electronic equipment, privacy protection can be achieved.

Description

technical field [0001] The embodiments of this specification relate to the field of computer technology, and in particular to a privacy protection-based image processing method, device, and electronic equipment. Background technique [0002] At present, biometric technology is widely used in various fields and is one of the main means of authenticating user identities. In related technologies, a terminal device may collect a biometric image, and may send the biometric image to a server. The server may receive the biometric image; the biometric image may be used to authenticate the identity of the user. [0003] During the above processing, it may cause leakage of private information in the biometric image. Contents of the invention [0004] Embodiments of this specification provide a privacy protection-based image processing method, device, and electronic device, so as to protect private information in a biometric image. The technical solutions of the embodiments of thi...
