Description
Technical Field
The invention relates to the technical field of information, in particular to a medical data sharing method based on a block chain.
Background
The blockchain technology is a technical scheme for decentralized and collective maintenance of a distributed account book, and is essentially a distributed database system with a plurality of nodes participating together, the blockchain is not a single technology, but a result of multi-technology integration, a reliable and difficult-to-tamper account book record is maintained by using the blockchain, trust risk can be reduced, and maintenance cost of many participants is effectively reduced. When the data is stored through the block chain, the consensus among multiple parties is required to be obtained, and the data cannot be falsified or forged after the data is chained.
The existing medical data are very sensitive personal data information which are stored by hospitals, because the personal medical history and case information of a user are very private, the data taken by the hospitals are difficult to share with other hospitals, for the same patient, most of the information such as the past medical history of the patient can be obtained only by dictating the patient, the accuracy is difficult to guarantee, and the diagnosis of the hospital on the patient is possibly influenced. The demand of institutions such as insurance companies for information such as past medical history of users is more extensive, but hospitals cannot directly provide patient information, so that the insurance companies and the like often find the conditions of patient cheating and the like, and the selective sharing of medical information is an urgent problem.
Disclosure of Invention
In view of the defects of the prior art, the invention discloses a block chain-based medical data sharing method, which aims to get through medical data among different hospitals, facilitate information intercommunication among the hospitals, ensure data right through access control, ensure that every use of the data is recorded and searchable through behavior records, commonly maintain a list library capable of providing services for all the hospitals, pay certain query cost when a request of query services is made by an insurance company, a superior department and the like, call original data through a block chain according to categories needing to be queried, input results into a sandbox safety bin for recalculation after the original data are calculated at the edge of each hospital system, and finally feed back the query results to prevent data leakage.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a blockchain-based medical data sharing method, the method comprising: a memory, a processor, and a blockchain based medical data program stored on the memory and executable on the processor, the blockchain based medical data program being implemented when executed by the processor; the program comprises intelligent contracts in the block chain for calculating medical data.
It should be noted that the method further includes: using hospitals with required medical data sharing as nodes to jointly construct a medical data sharing chain;
each hospital participating in sharing uploads the data hash and the addressing hash of the data address to a medical chain through an intelligent contract, and obtains other node consensus;
according to the data type shared by each hospital, each hospital commonly discusses a sharable data result list, and the usage rule is stored on the block chain through an intelligent contract and is commonly identified through each node;
according to the result of each calculation, each hospital respectively selects to build an edge calculation center of itself locally, and the edge calculation center is driven by an intelligent contract.
It should be noted that the method further includes: when a user needs to query, a list provided to the user selects one item of content.
It should be noted that the method further includes: and calling an intelligent contract for addressing according to the category to be inquired, and inquiring the data to address and call the data at the position of the original data of different hospitals.
It should be noted that the present invention further includes: a sandbox secure bin for computing data.
It should be noted that the present invention further includes: before the data enters the sandbox safety bin for calculation, the data needs to enter an edge calculation center which is deployed by each hospital node and is based on self data calculation, the edge calculation center calculates an intermediate result from the original data, and the intermediate result is input into the sandbox safety bin.
It should be noted that the present invention further includes: and the sandbox safety bin carries out secondary calculation on the intermediate result, outputs a final result, destroys the intermediate result after calculation, and records the behavior on the block chain.
As a preferred technical solution, if the superior department needs to supervise the system, a node may also be deployed in the superior department, and if data such as social security needs to be utilized, a node may also be deployed in the local social security. The user inquiry payment can adopt an offline payment form and an offline contract, and can also establish token rules and adopt a token payment form when the system is deployed. The behavior on different queryable lists and different behavior queries can set different amounts of the token to be queried and token acquisition methods of the system, and when someone queries, token distribution rules of all nodes are stored on a block chain through intelligent contracts and are commonly identified through all the nodes. And after the user bases the method, issuing the tokens according to the intelligent contract.
The invention has the beneficial effects that:
1. and (4) trustable storage of the data directory. The authenticity and the safety of data are guaranteed by using the characteristics of block chain distributed storage, time stamping and non-tampering.
2. And data resource sharing is safe. In the system, the private data access authority of each node is completely controlled by each node, access to any other node, other users and the like is forbidden under normal conditions, when query calculation is carried out, an intermediate result is calculated by an edge calculation program deployed in the local of a hospital through intelligent contract drive and then enters a sandbox safety bin, and data is destroyed after the safety bin is calculated. Can completely ensure that the original data is not leaked, and effectively ensure the privacy of patients
3. Enabling parties, enabling hospitals because the chain can share data, enabling more accurate diagnosis of users, other institutions such as insurance companies can pay for the use of querying their required data, such as whether the user can maintain information.
