Abstract

The invention relates to a face picture encryption method and a device thereof, computer equipment and a storage medium, and belongs to the technical field of artificial intelligence. The method comprises the following steps: acquiring N face pictures with a time sequence; performing feature extraction on the N face pictures, and obtaining picture features corresponding to the N face pictures; sequentially inputting the picture features into a recursive network in an image prediction model according to a time sequence, and outputting respective prediction information of the N face pictures; using the prediction information is used for indicating a prediction result of the corresponding face picture; wherein the recursive network is a network for predicting the input picture features through state information, and updating the state information based on the picture features of the input face picture; and encrypting the N face pictures based on the respective prediction information of the N face pictures. According to the scheme, the condition that the encryption format of the face image is easy to crack is avoided, and the security of the encrypted face image is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of artificial intelligence, and in particular to a face image encryption method, device, computer equipment, and storage medium. Background technique [0002] Nowadays, with the increasing development of artificial intelligence, artificial intelligence technology is more and more widely used in life, including the application of face recognition technology. Face recognition can be used in payment scenarios to realize "swipe face" payment. [0003] In related technologies, in order to ensure the security of the facial recognition data collected by facial recognition, it is usually necessary to encrypt the facial recognition data. The commonly used encryption method is to encrypt the facial recognition data according to a certain encryption format using an asymmetric algorithm. Among them, the encryption format is usually a time stamp or a counter that introduces the facial recogni...
