Data processing method and device based on block chain, equipment and storage medium

Abstract

The embodiment of the invention discloses a data processing method and device based on a block chain, equipment and a storage medium. The method comprises the steps of receiving an acquisition request of a first medical institution for medical data of a target user; reading an authorization record about the medical data of the target user from the first block chain network according to the acquisition request; verifying whether the first medical institution has the authority of acquiring the medical data of the target user according to the authorization record; if the first medical institution does not have the authority, refusing to send the medical data of the target user to a terminal device corresponding to the first medical institution; and if the first medical institution has the authority, reading the medical data of the target user from the second block chain network, and sending the medical data of the target user to a terminal device corresponding to the first medical institution. By adopting the method and the device, the medical data of the target user can be safely shared among multiple medical institutions, the method and the device are suitable for the field of smart medical treatment, and construction of a smart city can be further promoted.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular to a data processing method, device, equipment and storage medium based on blockchain. Background technique [0002] With the wave of digitalization brought by the Internet to the entire industry, more and more medical institutions already have relatively complete information infrastructure and Internet application systems, and have accumulated a large amount of electronic medical data, including image data. , electronic medical record data, inspection test report data, etc. However, a large amount of medical data lacks security and privacy protection, which makes it difficult to promote the emerging business model of "Internet medical care". At the same time, due to problems such as high data maintenance costs and complex operations among most medical institutions, it is difficult to share users' medical data among medical institutions.
