Embodiment Construction

[0114] The method for transaction and sharing of medical data based on blockchain technology will be further described below in conjunction with the accompanying drawings.

[0115] refer to figure 1 , which describes the process of generating the source data link. There are three types of nodes maintaining the chain, namely device nodes, doctor nodes and personal nodes.

[0116] The device node is the source of data generation. For a disease that may experience multiple medical device nodes, multiple data sources will be generated; the doctor node is the doctor in charge of the patient, and its main function is to check the logarithm and endorse it; The functions of personal nodes and doctor nodes are similar, and they mainly verify and endorse data. After the data passes the consensus of these nodes, the hash value and endorsement process of the original data generated by the device nodes are stored on the source data chain, and the original data is stored in the hospital d...

Abstract

A medical data transaction and sharing method based on the block chain technology specifically comprises the following steps: step 1, original data is generated by equipment nodes, endorsement is requested from the nodes according to contracts signed by doctor nodes and personal nodes, the endorsement is stored into a source data chain after consensus, and the original number is ensured to be realand effective; 2, the personal node or the hospital ownership confirmation node initiates an ownership confirmation request, a contract signed with other hospital ownership confirmation nodes in thealliance chain is requested for endorsement, the contract is stored in the ownership confirmation chain after consensus, the ownership problem of transaction data ownership is solved, and therefore the ownership problem of transaction interests is solved; and step 3, the transaction node of a certain hospital initiates a transaction request to the transaction node of the data providing hospital, requests endorsement and consensus from the transaction node according to the contract signed by the provider, and then stores the endorsement and consensus into a transaction chain, thereby ensuring that each transaction is real and effective and has a reference. The data protection area isolates the data user from the data, so that the data security is ensured.

Description

technical field [0001] The present invention constructs a decentralized data transaction (sharing) platform through block chain technology, and solves the authenticity and validity of data through the source data chain; solves the ownership problem of data through the confirmation chain; through the traceability of the transaction chain Solve the real legality of the transaction process; through the data protection area, solve the problems of data security and privacy protection. Background technique [0002] Data has become an asset in the era of digital economy. Artificial intelligence, machine learning and deep learning technologies have greatly promoted the improvement of the efficiency and automation of health care services. The development of artificial intelligence and other technologies requires a large amount of data to support them. However, the data of a single department or institution itself is sometimes difficult to support the data required for deep learning,...
