Technical Field
The present invention relates to the field of block chain technology, and in particular, to a data controllable sharing method and system based on a data mapping relationship.
Background
In the current blockchain application scenario, different access right management requirements are imposed on the visitors of the chain, so for some data with high and low rights accessible, a corresponding access right control mechanism is required to control the access rights of the data with different rights.
The chain operator can only inquire the data of corresponding authority for the accessors with different authorities through the front system isolation area block chain accessor. However, blockchain visitors cannot directly access the blockchain, thus reducing trust in the chain operator. And if the front-end system does not set the authority properly, the isolation is invalid, and the problem that the low-authority visitor accesses the high-authority data occurs.
