Abstract

The invention provides a video encryption method, apparatus and device. The video encryption method comprises the steps of obtaining to-be-encrypted video data; splitting the to-be-encrypted video data into a plurality of mutually independent video frame images; generating an encryption key matrix of each video frame image according to the saliency map of each video frame image; and encrypting theto-be-encrypted video data in a pixel summation encryption mode according to the encryption key matrix of each video frame image to obtain encrypted video data. According to the embodiment of the invention, the method can achieve the encryption of the salient region of the to-be-encrypted video data, achieves the encryption process in an encryption mode of pixel summation which is easy to achieve, at least solves a problem that the calculation complexity is high when the video data is completely encrypted at present. And on the basis of reducing the calculation complexity and reducing the workload, the image processing accuracy is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a video encryption method, device and equipment. Background technique [0002] With the improvement of people's security awareness, the security of video data has been widely valued by the academic circles, and many encryption methods have been continuously proposed. At present, a commonly used method for encrypting video data is to completely encrypt the video data directly. However, because most video data has the characteristics of huge amount of information and high fault tolerance, the existing full encryption method has high computational complexity and consumes a lot of computational resources. Contents of the invention [0003] Embodiments of the present invention provide a video encryption method, device, and equipment to solve the existing problem of high computational complexity when fully encrypting video data. [0004] In order to solve the probl...
