Embodiment 1

[0050] The medical and health data management method based on the blockchain smart contract of the present invention utilizes the blockchain storage certificate and the blockchain smart contract technology to realize data exchange, and the data can only be transmitted to the data requester after being authorized by the data owner , to ensure the authenticity, completeness, and security of sharing and exchange of medical and health data, and at the same time ensure the confidentiality of private data during the exchange of medical and health data; as attached figure 1 shown, including the following steps:

[0051] S1. User registration process: The user registers with the real name in the medical and health data sharing and exchange center through the client and saves the user's identity credential information to the basic platform of the blockchain storage network;

[0052] S2. Data synchronization process: the data producer stores the Hash certificate of the user's medical an...

Embodiment 2

[0055] The medical and health data management method based on blockchain smart contract of the present invention comprises the following steps:

[0056] S1. User registration process: The user registers with the real name of the medical and health data sharing and exchange center through the client and saves the user's identity credential information to the basic platform of the blockchain depository network; as attached figure 2 As shown, the specific steps are as follows:

[0057] S101. The user registers with the real name of the medical and health data sharing exchange center through the client, and verifies the user name and certificate number; wherein, the user includes the data owner, data producer and data requester, that is, the user can be an individual, a hospital or an insurance company;

[0058] S102. The medical and health data sharing and exchange center generates a key pair (private key and public key) for the user, and the private key is stored in a cryptogra...

Abstract

The invention discloses a medical treatment and health data management method and system based on a blockchain intelligent contract, and belongs to the technical field of information security. The technical problem to be solved by the invention is how to realize the true integrity of medical treatment and health data, the privacy authorization of the medical treatment and health data and the confidentiality of the data exchange process. The adopted technical scheme is as follows: (1) the medical treatment and health data management method based on the blockchain intelligent contract uses blockchain evidence storage and the blockchain intelligent contract technology to realize that in data exchange, the data can be transmitted to a data requester only after the authorization of a data ownerto ensure true, complete and secure sharing of the medical treatment and health data, and the method comprises the following steps: S1, a user registration process, S2, a data synchronization process, and S3, a data authorization and exchange process; and (2) the medical treatment and health data management system based on the blockchain intelligent contract comprises a client, a medical treatment and health data sharing and exchange center, and a blockchain evidence storage network basis platform.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and system for managing medical and health data based on blockchain smart contracts. Background technique [0002] At present, with the promotion of electronic medical records in hospitals, hospitals have accumulated a large number of medical and health data of patients, and these medical and health data contain huge value. Therefore, many local governments have established medical and health data sharing and exchange platforms, collecting a large amount of medical and health data. With the promulgation of the "Network Security Law", user medical and health file data belong to the user's privacy data, how to ensure the authenticity and integrity of medical file data, how to ensure that the exchange of medical data is authorized by the user, and how to ensure data exchange The confidentiality of data in the process is a technical problem that needs to be sol...
