Block chain data query method, device and system, equipment and storage medium

Abstract

The invention discloses a block chain data query method, device and system, equipment and a storage medium, and relates to the technical field of data transmission, which aims at enabling a first terminal to be incapable of randomly obtaining an electronic medical record of a user, reducing the risk that information is maliciously spread, avoiding information diffusion, and is high in informationsecurity. The method comprises: when a query request is received, acquiring a first certificate private key, wherein the query request carries an information identifier; encrypting the query request by adopting the first certificate private key to generate a request ciphertext, and transmitting the request ciphertext and the first terminal identifier to the electronic medical record storage equipment; and receiving a feedback ciphertext returned by the electronic medical record storage device after the request ciphertext and the first terminal identifier are received, and extracting target medical information indicated by the information identifier from the feedback ciphertext.

Description

technical field [0001] The present invention relates to the technical field of data transmission, in particular to a blockchain data query method, device, system, equipment and storage medium. Background technique [0002] With the rapid development of Internet technology, the construction plan of the modern medical and health system is becoming more and more mature. It is estimated that by 2020, a comprehensive health information platform will be established to realize the interconnection of information among major hospitals in the area. The health information platform uses electronic medical records to store all patient data and update the data in real time. Currently established health information platforms usually rely on centralized information systems, and based on this centralized information system, electronic medical records are stored and updated. Transmission of data in electronic medical records. [0003] In related technologies, the centralized information syst...
