Interactive Sharing Method of Digital Media Image Information Based on Differential Privacy Protection

Because digital media image information is vulnerable to external attacks during interactive sharing, resulting in poor interactive sharing effect, a digital media image information interactive sharing method based on differential privacy protection is proposed. According to the sensitivity of digital media images, calculate the amount of digital media image information to be protected, and build a defense model of differential privacy protection mechanism. With LAN as the main communication medium, the C/S structure is used to realize the interactive management of digital media image information, calculate the information flow injected by a node to the interaction center, and ensure the smooth interaction process. The analysis of information set is in danger of being violated, revealing that the information set has the diversified characteristics of entropy to resist external attacks. Calculate the energy and distance of non-uniform clustering nodes, obtain the template mapping radius, and determine the weighted minimum value according to the residual energy of cluster heads and the spacing between clusters. Combined with multi-source information fusion method, the information sharing process of single node and multiple nodes is designed. The experimental results show that this method can realize information interaction, and the information is saved completely. The maximum amount of shared information is 900 bits, which has a good sharing effect.
