Blockchain data query method, device, system, equipment and storage medium

Abstract

The invention discloses a data query method, device, system, equipment and storage medium of a block chain, relates to the technical field of data transmission, and can prevent the first terminal from obtaining the user's electronic medical record at will, reducing the risk of malicious dissemination of information , to avoid the spread of information, and the security of information is higher. The method includes: when a query request is received, obtaining the private key of the first certificate, and the query request carries an information identifier; using the private key of the first certificate to encrypt the query request, generating a request ciphertext, and combining the request ciphertext and the first The terminal identification is transmitted to the electronic medical record storage device; the feedback ciphertext returned by the electronic medical record storage device after receiving the request ciphertext and the first terminal identification is received, and the target medical information indicated by the information identification is extracted from the feedback ciphertext.

Description

Technical field [0001] The present invention relates to the field of data transmission, and in particular, to a data query method, apparatus, system, device, and storage medium of a block chain. Background technique [0002] With the rapid development of Internet technology, the construction plan of health and health modern health care system is also increasingly mature. In 2020, a comprehensive health information platform will be completed to realize the interconnection of information between major hospitals in the region. The health information platform stores all the data of the electronic medical record in the form of a patient and updates the data in real time. The currently established health information platform is usually depends on the centralized information system, and the storage of electronic medical records is achieved based on the centralized information system. Transmission of data in electronic medical records. [0003] In the relevant technology, the centralized...
