Abstract
The invention discloses a data security access control method based on a block chain. In the method, the data provider can add the item of data transaction into the blockchain through an intelligent contract, when a data buyer wants to purchase, the data buyer can obtain the access right of the data through the intelligent contract of the data provider only by paying corresponding fee on the blockchain, and the data buyer can obtain the data wanted through the access right of the data. The invention links the data transaction process and automatically executes the issuance of the access control authority by using the intelligent contract of the block chain, thereby centralizing the data transaction process, greatly improving the efficiency of the data transaction and ensuring the transaction access of the data to be more credible.
Description
Technical Field
The invention relates to the field of blockchain technology and data security access, in particular to a data security access control method based on a blockchain.
Background
The blockchain technology is a novel decentralized protocol, digital currency transactions or other data can be safely stored, information cannot be forged and falsified, transaction confirmation on the blockchain is completed by all nodes on the blockchain together, consistency of the transaction confirmation is guaranteed by a consensus algorithm, a public account book is maintained on the blockchain, and any node of the public account book on a storage block is visible, so that the digital currency transactions or other data cannot be forged and falsified.
The intelligent contract is an assembly language programmed on the blockchain, is a section of automatically executable program deployed on the blockchain, and comprises a programming language, a compiler, a virtual machine, an event, a state machine, a fault-tolerant mechanism and the like in a broad sense. In other words, an intelligent contract is a contract that can be automatically executed on a computer system when certain conditions are met. Typically one will not write the bytecode itself, but will compile it from a higher level language, e.g. using a special purpose language like Solidity.
Data access security refers to the method by which an information system controls the ability of a user to view and modify data. These methods include browsing of logical views of data and authorization of individual users or groups of users to obtain data.
The existing data transaction can not be decentralized, the confirmation process of the data transaction and the authorization process of the security access control are extremely complicated, a lot of manpower and material resources are consumed, and a decentralized and data security access control method is needed to improve the data transaction efficiency and enable the transaction access of the data to be more credible.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a data security access control method based on a block chain, thereby solving the problem that decentralized data transaction cannot provide data security access pain points.
The purpose of the invention is realized by the following technical scheme: a block chain-based data security access control method is characterized by comprising the following steps:
the method comprises the following steps: contract deployment: after the data provider classifies and arranges the data required to be provided, the data and pricing are written into the intelligent contract according to the own needs, and after the security of the intelligent contract is checked, if the check is passed, the contract can be deployed on a block chain.
Step two: the data purchaser initiates a transaction on the blockchain: the data purchaser initiates a purchase transaction of the data, and writes transaction information into the block chain, at which time funds of the data purchaser are frozen.
Step three: the intelligent contract detects the transaction information: when the transaction information is written into the block chain, the intelligent contract is automatically executed, and the access right information of the data which the data buyer wants to purchase is provided for the data buyer according to the transaction information.
Step four: the data buyer acquires the data through the access right information: the data buyer obtains the data with data gap from the data provider through the specific interface by the authority information of data access returned by the intelligent contract.
Step five: the data provider provides data gap information to the upper blockchain: and the data provider provides the information of the data gap to the blockchain, and once the intelligent contract of the blockchain detects the chaining of the data gap information and checks the information as correct information, the frozen fund is transferred to the account of the data provider.
Further, the data of the data provider is stored locally at the data provider, rather than on a unified server.
Furthermore, the access right information provided by the data provider is provided by the intelligent contract in the block chain, and is automatically issued without the help of a central mechanism.
Further, the purchase amount paid by the data purchaser will be frozen on the blockchain for a period of time.
Further, the data provider provides the data with data gap to the purchaser after the money transaction is linked up, and then the gap information is linked up to complete the automated transaction.
Drawings
Fig. 1 is a flowchart of a block chain-based data security access control method according to the present invention.
Detailed Description
The present invention will be described in detail below with reference to the drawings and specific embodiments, and the objects and effects of the present invention will become more apparent.
As shown in fig. 1, the method for controlling data security access based on a block chain provided by the present invention includes the following steps:
the method comprises the following steps: contract deployment: after the data provider classifies and arranges the data required to be provided, the data and pricing are written into the intelligent contract according to the own needs, and after the security of the intelligent contract is checked, if the check is passed, the contract can be deployed on a block chain.
Step two: the data purchaser initiates a transaction on the blockchain: the data purchaser initiates a purchase transaction of the data, and writes transaction information into the block chain, at which time funds of the data purchaser are frozen.
Step three: the intelligent contract detects the transaction information: when the transaction information is written into the block chain, the intelligent contract is automatically executed, and the access right information of the data which the data buyer wants to purchase is provided for the data buyer according to the transaction information.
Step four: the data buyer acquires the data through the access right information: the data buyer obtains the data with data gap from the data provider through the specific interface by the authority information of data access returned by the intelligent contract.
Step five: the data provider provides data gap information to the upper blockchain: and the data provider provides the information of the data gap to the blockchain, and once the intelligent contract of the blockchain detects the chaining of the data gap information and checks the information as correct information, the frozen fund is transferred to the account of the data provider.
Preferably, the data of the data provider is stored locally at the data provider, rather than on a unified server.
Preferably, the access right information provided by the data provider is provided by an intelligent contract in the block chain, and is automatically issued without the help of a central authority.
Preferably, the purchase amount paid by the data purchaser will be frozen on the blockchain for a period of time.
Preferably, the data provider provides the data with the data gap to the purchaser after the funds transaction is linked up, and then links up the gap information to complete the automated transaction.
