A sharing method and system based on block chain, server and readable storage medium

Abstract

The embodiment of the invention discloses a data sharing method based on a block chain. The method comprises the following steps: writing encrypted service data uploaded by each service server into analliance chain; and according to the query request, decrypting the found target service data, and issuing the decrypted target service data to a corresponding service server. Since the uploaded service data is encrypted, the queried target service data needs to be decrypted and then sent to the corresponding service server and the alliance chain belongs to a block chain and has the characteristics of tamper-proofing, traceability and high security, the safety of the uploaded business data can be ensured, and the business server for inquiring the target business data cannot acquire which business server the target business data belongs to for uploading, so that the business data can be shared under the condition that the business confidentiality is not leaked; and corresponding risk management can be carried out according to the queried target service data, so that the service risk can be effectively reduced.

Description

technical field [0001] The embodiment of this description relates to the field of data processing technology, and in particular to a blockchain-based data sharing method, system, server, and readable storage medium.
