Information hiding method, device and system based on cavity space pyramid

Abstract

In order to solve the problems of low image information hiding capacity and distortion in the aspect of data privacy protection, the invention provides an information hiding method, device and system based on a cavity spatial pyramid, which are used for embedding and extracting watermark information in a protected image to realize image version authentication and protection. According to the method, a cavity space pyramid module is built by adopting cascaded and parallel cavity convolution layers, the receptive field is expanded, the multi-scale and multi-cavity-rate characteristics are extracted, information is more accurately hidden in a semantic redundancy position, and the decoding capability of a network on embedded information is improved; meanwhile, the decoding accuracy is improved by using cross entropy loss; in addition, the quality of the generated image is improved through residual error and linear operation confrontation in the discrimination network; finally, in order to improve the network stability, updating of different scales, cosine annealing adjustment and an intensive connection strategy are used in training. According to the method, high-capacity information hiding is achieved, meanwhile, it is guaranteed that images are not distorted, and experiments prove that the method has high information hiding capacity.

Description

technical field [0001] The invention relates to an information hiding method, device and system, and belongs to the technical field of multimedia information security and privacy protection. [0002] technical background [0003] With the development of Internet technology and artificial intelligence technology, the security and privacy of multimedia information has been widely concerned by people. How to efficiently protect multimedia information (text, image, audio, video, etc.) has become an important problem to be solved urgently. Information hiding hides secret information (text, watermark, key, etc.) in public multimedia information in an imperceptible way, making it difficult for people to visually judge whether the embedded information exists or not, thus protecting privacy and security. play an important role. In recent years, with the development of 5G communication and artificial intelligence technology, the generation, dissemination and acquisition of multimedia ...
