Abstract

The embodiment of the invention provides a privacy-protecting biological feature recognition method and device. According to one specific embodiment, the method comprises the steps that firstly, an original image collected by a lensless imaging device for biological characteristics is obtained, the lensless imaging device comprises a mask plate and an image sensor, and the original image is an image collected by the image sensor after being modulated through the mask plate; secondly, reconstructing the original image based on the modulation parameters of the mask plate to obtain a reconstructed image; secondly, performing feature extraction on the reconstructed image by using a pre-trained feature extraction network to obtain feature representation of the reconstructed image; and finally, based on the feature representation, performing biological feature recognition on the reconstructed image.

Description

[0001] This application is a divisional application of an invention patent application with the application number 202110849620.2 filed on July 27, 2021, entitled "Biometric Identification Method and Device for Privacy Protection". technical field [0002] One or more embodiments of this specification relate to the field of computer technology, and in particular, to a biometric identification method and device for protecting privacy. Background technique [0003] The continuous maturity and large-scale application of biometric identification technology have brought great convenience to our daily life. For example, the universal application of fingerprint payment, fingerprint time attendance, face payment, face time attendance, face recognition access control, etc., makes our life more convenient. However, while obtaining these conveniences, people are also paying more and more attention to their privacy protection. Now, cameras that can be seen everywhere can collect biomet...
