Title:
FACE IMAGE ENCRYPTION/DECRYPTION METHOD AND APPARATUS, ELECTRONIC DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/060666
Kind Code:
A1
Abstract:
Provided are a face image encryption/decryption method and apparatus, an electronic device, a storage medium, a computer program product, and a computer program. The face image encryption method comprises: performing frequency domain processing on an original face image to obtain N frequency domain face images at different frequencies, wherein N is a positive integer; obtaining encryption seeds; performing convolutional encryption on the encryption seeds and the N frequency domain face images to obtain respective encrypted frequency domain face images of the N frequency domain face images; and performing frequency domain inverse processing on the N encrypted frequency domain face images to obtain an encrypted face image.
