Problems solved by technology

This approach has two disadvantages: 1) It is difficult to ensure that the patient can accurately remember the quantitative values ​​of historical illnesses, such as blood pressure history records, etc.
2) Patients often include non-professional medical words when describing symptoms, which will affect doctors' understanding of patients' historical symptoms
Such a solution solves the problem of sharing medical records in different institutions and regions. However, a complete EMR file usually contains the patient's personal privacy information. Such an EMR file is transferred to a third-party cloud service organization for management and storage. No guarantees on privacy protection and security
Third-party cloud service providers are usually considered semi-reliable in cloud service research, because improper management of cloud services will cause data to be tampered with, leaked or even lost
Therefore, cloud servers with a centralized structure have many problems in terms of data privacy and security.

Embodiment Construction

[0020] The method for safely storing and accessing medical records based on the block chain network of the present invention comprises the following steps:

[0021] 1) Establish several nodes in the blockchain network, and deploy a management terminal or server on each node. The management terminal is used to manage electronic medical record files and perform the same operations on multiple nodes, including managing uploaded files, updating files, and downloading files , the server is used to execute electronic medical record file transmission, and deploy smart contracts for electronic medical record file storage, upload and download on the blockchain network;

[0022] 2) The patient registers on a node of the deployment management end, which creates three digital passwords for the patient: the unique ID encrypted by the hash algorithm SHA-256, and the public-private key pair PK and SK encrypted by the ECC algorithm , and FolderAddress of the medical record folder address afte...

The invention discloses a medical record secure storage access method based on a block chain network, and aims to solve four core problems in the medical record EMR field at present: 1) how to safelyand effectively store the EMR of a patient, 2) how to upload the EMR in real time, and 3) how to set access control to filter illegal persons. and 4) how to facilitate cross-domain downloading of theEMR provides an electronic medical record ERM storage and management framework based on a block chain technology, and the framework can well solve the privacy and security problems of user data.

Description

technical field [0001] The invention relates to a method for safely storing and accessing medical records based on a block chain network. Background technique [0002] Traditionally, medical record information includes the patient's basic information, examination symptoms, doctor's order information, and non-text examination information (including ultrasound images, MRI images, etc.). It provides a basis for making a judgment on the condition, and also provides a basis and reference for other medical staff to make a correct assessment of the patient's condition, understand the historical treatment plan, and further formulate a personalized treatment plan. In terms of comprehensive and complex diseases and various chronic diseases for doctors, a reliable, safe and accessible electronic medical record file will undoubtedly provide better results in improving the search speed of medical documents and formulating reasonable plans for comprehensive assessment of patients. For a ...
