With the aim of achieving secure data storage and sharing,a trusted data secure storage and sharing system based on IPFS and blockchain technology is proposd.The system uses the secure storage node in the data storage layer to store security data,and then uses Ethereum,which is composed of several blocks in the blockchain network layer,as the network for secure data transmission,to transmit security data to the data management layer.The management layer is responsible for performing the logical operation functions of data storage,data encryption,and blockchain invocation,and connecting with the interface service layer,and connecting with the administrator.It implements data access control,data request services,and other data security transmission and shares functions between data owners and data requesters.The experimental results show that the coupling value of the system during operation is higher,and the system has good stability performance.The execution efficien-cy is good when encrypting data,which can effectively control data access and sharing,and has stronger applicability.
