MIFS: A Peer-to-Peer Medical Images Storage and Sharing System Based on Consortium Blockchain

As computer vision has continued to make significant breakthroughs in recent years, medical image processing has become a research hotspot. However, hospitals that generate medical images have difficulty sharing this data due to differences in information systems and centralized storage structures. As a result, researchers often have access to only a small number of samples for research. To solve medical image resource sharing, we propose MIFS, which stores, retrieves, authorizes, and shares medical images among hospitals. MIFS proposes a peer-to-peer data storage scheme based on consortium blockchain and an authentication mechanism compatible with the consortium blockchain. On this basis, MIFS proposes a blockchain-based access control scheme and a process for retrieving, authorizing, and sharing medical images. Finally, we implemented and evaluated the system to prove the feasibility of our scheme.
