Abstract

The invention provides an image encryption storage method and device. The method comprises the following steps: uniformly partitioning an acquired original image to obtain a plurality of image blocks;performing pixel position scrambling on the plurality of image blocks to generate a position scrambled image; chaos scrambling of pixel values is carried out on the position scrambling image to generate a final encrypted image; and storing the final encrypted image. By performing dual encryption of pixel position scrambling and pixel value scrambling on the image, the safety of image storage is greatly improved, and information leakage is effectively prevented. The scheme of the invention is particularly suitable for encrypting and storing the face image acquired in the face recognition process, can keep all the original features of the face image to meet the application requirements of a subsequent face recognition system, can effectively protect the privacy of customers, and greatly reduces the risk of data leakage.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image encryption storage method and device. Background technique [0002] With the increasing application requirements of information security, access control, and video surveillance, face recognition technology has been widely used in various social life and work scenarios. The first step in the face recognition system is the collection and storage of face images. For image storage, there are two commonly used methods: first, the original image is stored in the file system, and the file path is stored in the database; second, the image is directly decomposed into RGB and stored in the database. These two methods can efficiently and conveniently complete image storage, reading and recognition. [0003] However, in order to facilitate the subsequent operation of the face recognition system, the above-mentioned face image storage methods do not encrypt the image itsel...
