Abstract

The invention provides a financial institution user data sharing method and system based on a block chain technology, and the method comprises the steps: S1, enabling each client to obtain authorization through an admission mechanism, and adding the authorization into a block chain sharing platform to serve as different nodes of a block chain; S2, enabling the client to input query request data and configures a query rule according to a user-defined query template; S3, enabling the block chain sharing platform to verify and authorize the query party client, and return inquirable list data; AndS4, enabling the query party client to encrypt the query request data in the form of a queried client key according to the list data, and querie and return result data according to the configured query rule. According to the method, financial platform user data sharing is achieved, desensitization, encryption and other technologies are adopted for multiple protection, original data cannot be checked, and the safety and integrity of the data cannot be affected; Based on the blockchain technology, a distributed transaction account book is co-built, and query information is accurately recorded and cannot be tampered.
