ABSTRACT
In order to realize the safe storage and sharing of medical data, this paper proposes a medical data storage model based on blockchain. Firstly, all medical institutions are divided by regions, and multiple medical institutions alliances are generated, and the consortium blockchain is formed respectively. The medical metadata is stored on the blockchain, and the medical data block is stored in InterPlanetary File System (IPFS). In each consortium blockchain, a small number of authoritative organizations are selected to form a main chain, which is responsible for the cross chain query function among the consortium blockchains. In the query process, the proxy re encryption technology is used to realize the user's access to the patient's medical information. The experimental results show that the model ensures the tamper proof and security of medical data, It realizes the safe sharing of medical data and improves the query efficiency of medical data, When 78.5% of the total number of queries in the same alliance, the cross chain scheme is better than the ordinary scheme.
