Alliance chain data shielding method and system and computer readable storage medium

Abstract

The invention discloses an alliance chain data shielding method and system and a computer readable storage medium. The alliance chain data shielding method comprises the steps that a supervision node receives a data detection request sent by a client according to user operation; the supervision node selects a key information detection algorithm according to the data detection request; the supervision node executes the selected key information detection algorithm to detect a data packet carried by the data detection request; the supervision node sends a detection result to the client, so that when the detection result is that detection is passed, the client writes data written by the user into the block chain node, or returns data read from the block chain node to the user; on the contrary, the client does not write the data written by the user into the block chain node or does not return the data read from the block chain node to the user. According to the method, a block chain node network does not need to be transformed, universality is high, implementation is easier, a dynamic strategy adjustment function is achieved, and traceable and reducible data shielding can be achieved on the premise that tampering cannot be achieved.

Description

technical field [0001] The present application relates to the technical field of block chains, and in particular to a data shielding method of a consortium chain; it also relates to a data shielding system of a consortium chain and a computer-readable storage medium. Background technique [0002] With the rapid development of alliance chain technology, alliance chain technology has been widely used in various fields such as finance, law, medical care, energy, entertainment, and justice. As an important type of blockchain, a consortium chain refers to a blockchain that is jointly managed by several institutions or organizations. The data in its nodes only allows institutions or organizations in the system to read and send transactions, and jointly record transaction data. Information added to the blockchain is permanently stored. The blockchain has the characteristics of global data sharing and non-tampering. If criminals write harmful information, Internet rumors, inflamma...

Problems solved by technology

In addition, although some manufacturers use smart contracts to determine shielding conditions and encrypt illegal information or delete decryption keys for data shielding, but in this way, the determination of shielding conditions depends on the client to vote, and there is no dynamic policy adjustment Function

Data recovery is more difficult after the data is masked and the decryption key is deleted
