Medical data storage method based on block chain technology and information data processing terminal

Abstract

The invention belongs to the technical field of information retrieval and database structure, and discloses a medical data storage method based on the block chain technology and an information data processing terminal. The data storage method comprises the steps that the user establishes the identity address; the patient authorizes the third-party agency to store his data; the agency verifies theuser identity; the data are labeled and classified after successful verification and then encrypted and stored; the storage record is added to the block; and the patient and agency contract is updated. The data access comprises the steps that the user establishes the identity address; the accessor accesses the data to the agency according to the tag class; the agency verifies the user identity; the patient opinion is taken after successful verification; the private key is transmitted through the agency after agreement of the patient and the accessor is enabled to acquire the data and decrypt the data; the access record is added to the block; and the patient, agency and accessor contract is updated. The method has high security and high practicality. The method is mainly applied to the aspect of medical data storage and sharing of various hospitals.

Description

technical field [0001] The invention belongs to the technical field of information retrieval and its database structure, and in particular relates to a medical data storage method and an information data processing terminal based on block chain technology. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: most of the current data systems use centralized storage, and the data Stored in the server, once the data in the server is hacked, all data will be used by hackers at will. due to the hospital There are also medical institutions that have independent databases. When sharing data across institutions, cumbersome procedures will be required, and due to storage It seems that the format is different. Even if the data is obtained, it will take a lot of effort to convert the data into the required format. The storage and sharing of users' medical data is of great practical value to both personal health plan for...

Problems solved by technology

There are many deficiencies in the use of the above data systems: they are basically centralized management, so once the security of the central node is threatened, the security of all data cannot be guaranteed; It is difficult to unify the structure when storing, so it will bring a lot of difficulties when sharing data with medical institutions or medical research institutes; it is difficult for many patients to know where their data will be disseminated in the future after the medical data is stored and recorded by the hospital. What is the data used for, and whether it is applied where the patient is not willing; patient data is easily stored in different hospitals, which will cause great inconvenience when the patient needs the previous data in the future

[0004] (1) Most of the existing data systems use centralized storage when used, and the data is stored in the server. Once the data in the server is attacked by hackers, all the data will be used by hackers at will, and the security of all data cannot be guaranteed; Since hospitals and medical institutions have independent databases, cumbersome procedures will be required when sharing data across institutions, and even if the data is stored in different formats, it will take effort to convert the data into the required format later. When sharing data It will bring a lot of difficulties; it is difficult to know where your data will be disseminated in the future and what the data will be used for, whether it will be applied to places that patients do not want; patient data can easily be stored in different hospitals, and in the future Great inconvenience when patients need previous data

[0005] The difficulty and significance of solving the above technical problems: The invention encrypts the data and stores them. Even if it is stolen by an attack, the original data will not be exposed and the security of the data is protected. However, the encryption algorithm must ensure that it is difficult for hackers to break through and the efficiency should not be too low.
