Blockchain and interplanetary file system-based solution for storing and sharing electronic health records

  Objective  To design a decentralized electronic health record (EHR) storage system to effectively address the problems of secure storage, efficient management, and cross-regional utilization of EHR.

  Methods  A technical solution based on integrated blockchain and interplanetary file system (IPFS) technology was proposed to achieve secure storage and sharing of EHR. By taking advantage of blockchain, the system can collaborate with EHR owners, managers and users to achieve secure management and sharing of files across regions. By using the distribution characteristics of IPFS to store HER can reduce storage costs and improve security.

  Results  The EHR storage system established based on information technology such as blockchain and IPFS has the characteristics of cross-regional utilization, decentralization, secure storage and easy promotion.

  Conclusion  This storage system can guarantee the integrity, security and personal privacy of EHR, realize cross-regional business collaboration, address the problems of combination and transferring of files across regions, and provide technical support for the secure promotion and application of EHR.
