Problems solved by technology

This method requires high professional knowledge of the data owner, reduces the availability of the system, and increases the labor cost to a certain extent.
At the same time, this method needs to develop a separate smart contract for each data that needs to be circulated, which also consumes the storage and network resour

Embodiment Construction

[0037] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] Such as figure 1 , user A, as the owner of the data, plans to use his data for circulation, and he enjoys the data rights that need to be protected. Users B and C, as transferees who need data, plan to apply for circulation to obtain the data. Prior to this, the smart contract in this method, that is, the rights and interests protection system, has been deployed on the blockchain and stored on the kth block of the blockchain system. The system includes four functions: the data publishing function and the license verification function provided for the data owner, the circulation application judgment and the license generation and authorization function provided for the data transferee. The concrete steps of this method are:

[0039] 1. User A, as the data owner, formulates the data circulation strategy according to the data rights that he needs to protect, a...

Abstract

The present invention belongs to the data safety technology field, especially to an enhanced data right protection method based on a block chain and a smart contract. The method comprises the steps: a data owner submits data attributes and strategy attributes to a smart contract at a block chain for data publishing; other users are taken as data assignees to allow the circulation attributes of the data assignee to take as parameters to call the smart contract to perform circulation application, after the smart contract automatically determines whether the application is valid or not according to the strategy attributes of the data, an application result is returned back; if the circulation attributes of the data assignees are valid, a circulation license authorized and generated by the smart contract is obtained; or else, the smart contract determines that the application is failed. The enhanced data right protection method based on the block chain and the smart contract applies the block chain technology to protect data owner right and justly accept the applications of each data assignee; and moreover, the enhanced data right protection method based on the block chain and the smart contract improves the system stability, remove the dependence on a third-party authority in the data right protection process and provide a just, transparent and trusted execution environment for the data circulation process.

Description

technical field [0001] The invention belongs to the technical field of data security, and specifically relates to an enhanced data rights and interests protection method based on block chains and smart contracts. Background technique [0002] In recent years, with the rapid development of Internet information technologies such as big data analysis and data mining, massive data has attracted more and more attention, and has been gradually used effectively by various industries, such as improving user experience and accurately placing user advertisements. predict disease, etc. At present, the application of big data technology has begun to penetrate into all aspects of society, including business, medical care, government, education, economy, humanities, entertainment, technology and other fields. Enterprises or individuals can obtain more useful information from raw data through big data technology, making data more and more valuable and scarce at the same time. Therefore, ...
