Abstract

The embodiments of this specification disclose an image processing method, apparatus and electronic device based on privacy protection. The method includes: acquiring a depth image and a color image, wherein the depth image and the color image contain private information of the same object; decomposing the depth image to obtain low-frequency information of the depth image; Perform decomposition to obtain high-frequency information of the color image; and generate a desensitized image after protecting the privacy information according to the low-frequency information and the high-frequency information. The image processing method, apparatus, and electronic device in the embodiments of this specification can implement privacy protection.

Description

technical field [0001] The embodiments of this specification relate to the field of computer technologies, and in particular, to an image processing method, apparatus, and electronic device based on privacy protection. 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 the related art, the terminal device can collect the biometric image, and can send the biometric image to the server. The server can receive the biometric image; the user identity can be authenticated using the biometric image. [0003] In the above processing process, it may cause the leakage of private information in the biometric image. SUMMARY OF THE INVENTION [0004] The embodiments of this specification provide an image processing method, apparatus and electronic device based on privacy protection, so as to protect the privacy information in the biometric image. The technical solutions of...
