Problems solved by technology

[0005] Aiming at the fact that current medical data cannot be freely transferred between different medical institutions, and the security of different medical data in the sharing process, the present invention proposes a blockchain-based on-chain-off-chain medical data sharing method and device And equipment, build a lightweight distributed ledger, which only contains lightweight messages, such as server storage addresses of medical data, transaction records, upload / download operations, authorization records, etc.; at the same time, real medical data is still stored in In the local server; this mode of lightweight ledgers on the chain and real data stored off the chain will greatly save public cloud resources, which is very conducive to promoting the safe cross-institutional sharing of medical data resources among different medical institutions and protecting the privacy of patients Safety

Embodiment 1

[0033] Example 1, such as figure 1As shown, a blockchain-based chain-off-chain medical data sharing method uses alliance chain technology to build a medical alliance including patients, doctors, researchers, medical institutions, banks and insurance institutions, and builds a medical alliance based on A distributed health chain system; different medical institutions use the alliance chain to form a distributed health chain system, the health chain system includes consensus nodes, system nodes and other nodes; consensus nodes refer to different medical institutions, Participate in the management and maintenance of the health chain system; system nodes refer to patients, doctors and researchers, upload, manage and trade their own medical data; other nodes refer to banks and insurance institutions. In addition, the medical alliance health chain also includes other nodes, such as account center and audit center.

[0034] like figure 2 As shown, the medical alliance includes pat...

Embodiment 2

[0061] Embodiment 2, a blockchain-based on-chain medical data sharing device, including an acquisition module, a processing module, a sharing module, and an accounting module; the ciphertext data, and initiate permission acquisition; the processing module, the medical data provider verifies the medical data user, and after passing the verification, authorizes its access right to the medical data; the sharing module, the The medical data sharing behavior is completed, and the sharing behavior establishes a new transaction and stores it in the temporary block in the medical health alliance; the accounting module broadcasts the shared transaction record reached to the health chain All consensus nodes, when the temporary block where the transaction is located reaches a consensus through the verification of all the consensus nodes on the healthy chain, the transaction will become unavailable after the temporary block is linked to the healthy chain falsified records.

Embodiment 3

[0066] Embodiment 3, a computer device, including a computer-readable storage medium and a processor, the computer-readable storage medium and the processor load and execute a blockchain-based on-chain-off-chain medical data sharing method. A computer program is stored in the computer-readable storage medium, the computer program includes program instructions, and the program instructions are loaded by the processor to execute the blockchain-based on-chain-off-chain medical data sharing method.

Abstract

The invention provides an on-chain-off-chain medical data sharing method, device and equipment based on a block chain, and the method comprises the steps: constructing a medical alliance comprising a patient, a doctor, a researcher, a medical institution, a bank and an insurance institution through employing an alliance chain technology, and constructing a distributed health chain system based on the medical alliance; generating medical data after a patient sees a doctor, sharing and storing the medical data in a local server of a medical institution by the patient, and then uploading an index of the medical data to a health chain system; obtaining the storage address from the health chain system through the index by a medical data user, and obtaining the required medical data after obtaining authorization; and after the medical data sharing behavior is completed, forming a determined transaction, and verifying and broadcasting the determined transaction to the health chain system. By means of the method, safe storage and sharing of the medical data can be achieved, the searchable safety of the medical data is improved, and redundancy of a health chain account book is effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a blockchain-based on-chain-off-chain medical data sharing method, device and equipment. Background technique [0002] Blockchain, in simple terms, is a chain structure formed by connecting different blocks in chronological order. Among them, the data and transactions are packaged and verified by different nodes, and recorded on the unified distributed ledger of the whole network; the consensus of the whole network without trust is realized through mechanisms such as proof of work and proof of rights; The security of the transmission and storage process is guaranteed. Blockchain technology solves the problems of centralization and data islands in the traditional medical service system, and establishes a distributed electronic medical record storage management and sharing platform. However, some new problems have also been exposed, such as bloated ledgers, poor data s...
