Abstract

The invention provides an image processing method, device and equipment and a storage medium. The method comprises the following steps: determining a quaternion matrix corresponding to each frame of image in multiple frames of images, wherein the multiple frames of images comprise a first frame of image and a second frame of image; processing the quaternion matrix corresponding to the first frameimage to obtain a first amplitude and a first phase of the first frame image; processing the quaternion matrix corresponding to the second frame image to obtain a second amplitude and a second phase corresponding to the second frame image; and taking the first amplitude and the second amplitude as a ciphertext of the multi-frame image, and generating a key of the multi-frame image according to thefirst phase and the second phase. According to the invention, the first amplitude, the first phase, the second amplitude and the second phase are quickly determined, and the secret key of the multi-frame image is generated according to the first phase and the second phase, so that the security of the encrypted image is higher, and the transmission efficiency is effectively improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to an image processing method, device, equipment, and storage medium. Background technique [0002] As people's daily life and work enter the era of big data, massive images, sounds and other massive data are shared and transmitted through the Internet every day. Information and data have become one of the most important resources of human society. [0003] In the era of big data, these data contain some sensitive and private information. Improper use of related data may easily cause information insecurity, especially the simultaneous leakage of multiple sets of data with certain relevance, causing a chain of events. Reactions can make problems worse. Image encryption can transform meaningful image data into meaningless data similar to random noise, effectively hiding the content of the image and protecting the security of image information. [0004] Howeve...
