Abstract

The invention discloses a convolutional neural network face recognition method and device based on privacy protection, and the method comprises the steps: obtaining a plurality of face images, and carrying out the preprocessing of the plurality of face images; calculating local variances of the plurality of preprocessed face images; constructing a first complex matrix by taking a plurality of faceimages before preprocessing as real part vectors and taking local variances of the plurality of face images after preprocessing as imaginary part vectors; performing double random phase encryption ofa transform domain on the first complex matrix to generate a second complex matrix; and extracting a first component and a second component from the second complex matrix, respectively inputting thefirst component and the second component into the convolutional neural networks for training, connecting the two trained convolutional neural networks to generate a face recognition encryption network, and recognizing the face image through the face recognition encryption network. The method has high safety and can meet different requirements of face recognition.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a privacy protection-based convolutional neural network face recognition method and device. Background technique [0002] Face recognition mainly relies on people's facial information, and its applications in real life are becoming more and more extensive, such as unlocking mobile phones, face payment, etc. Amazon, Google, and Microsoft have successively launched face recognition software. [0003] And this kind of biological information is unique as an important biological feature. In fact, there are many small secrets hidden in it, such as age estimation based on face images, gender identification, and blood relationship identification. Usually our photos are used to train face recognition systems without permission, and many users have been violated without knowing their rights to know and privacy. This year, San Francisco and Somerville in the United States ...
