Embodiment 1

[0044] In the registration contract module, this global contract will match the identity string of the participants with their Ethereum information (such as their sum should be equal to a public key). In it, plain text strings are directly used for identity verification instead of encrypted public key verification methods, and existing identity formats are allowed to be used to simplify the system as much as possible, reduce the amount of calculation, and improve system performance. However, in order to ensure the rationality of the system, it is allowed to manually adjust the rules for registering new users and modify the existing mappings. The registration of identities is only managed by certified management agencies. The registration contract also maps the identity string to another blockchain address, which is the summary contract.

[0045]In the system, when a node needs to store and manage medical data for another node, they will sign a relationship contract between th...

Abstract

The invention provides a medical big data management system and frame based on a block chain and belongs to the technical field of a smart contract. The invention mainly comprises an integrated frame structure of the system, a registration contract part, a digest contract part and a relation contract part of users and medical record data providers. The whole medical big data management system takes the block chain as the technology base. The users can directly, effectively, rapidly and selectively manage own medical record privacy. The block chain has two characteristics: decentration and tamper resistance, so the truest and most convenient service is provided for the users, comprising patients, hospitals and data warehouses, and the data processing pressure of the data warehouses due to big data centralization is mitigated.

Description

technical field [0001] The invention relates to the technical field of block chains with smart contracts, in particular to a block chain-based medical big data management system and framework. Background technique [0002] With the continuous development of big data and cloud platforms, big data security and cloud security are also placed in the main position. Among them, medical data is important private data, involving a wide range of people, and due to the continuous transfer of patients, medical record data is constantly disseminated in multiple ways, which can easily leak the privacy of patients and bring troubles to patients. [0003] Due to the large number of medical data categories and samples, these huge data bring unbearable data processing pressure to the database center. Therefore, a blockchain-based medical data management system is proposed. According to the characteristics of the blockchain, this system can carry out "decentralized" dissemination and sharin...
