Problems solved by technology

The explosive growth of data volume has led to the gradual emergence of data security, circulation, sharing and privacy protection issues. Now data sharing is becoming more and more open. With the increase of access personnel, it brings data sharing that cannot be controlled and sensitive. There is a risk of error in manual data processing, and problems such as data leakage cannot be investigated

Abstract

The invention discloses a data differential privacy protection sharing platform based on a block chain. The data differential privacy protection sharing platform based on the block chain comprises a data uploading module, a data access module, a data processing module and an intelligent contract module, and the data processing module comprises a hierarchical access control module, a data optimization module, a data query component and a credibility evaluation feedback module. The data differential privacy protection sharing platform is used for solving the problem of privacy leakage caused bya transaction process between a data provider and a data visitor in the prior art, and by realizing de-intermediation operation, the provider can obtain corresponding value income while sharing own health data for scientific research institutions and the like.

Description

technical field [0001] The invention relates to block chain information technology, in particular to a block chain-based data sharing platform. [0002] technical background [0003] In the past two years, the wave of big data development has swept the world. It is estimated that by 2020, the total amount of global data will reach 40ZB, and the global big data market will reach 80 billion US dollars. The explosive growth of data volume has led to the gradual emergence of data security, circulation, sharing and privacy protection issues. Now data sharing is becoming more and more open. With the increase of access personnel, it brings data sharing that cannot be controlled and sensitive. There is a risk of error in manual data processing, and data leakage cannot be investigated. How to achieve data sharing while safely managing the privacy of data providers has become an important topic in the current data technology field. Contents of the invention [0004] In order to sol...
