Data trusted security sharing system and method based on block chain technology

Abstract

The present application discloses a data trusted security sharing system and method based on area chain technology. The system comprises a data registration platform, a data management platform, a security computing platform and a block chain. The data registration platform registers the data uploaded by the data publisher uniformly, which realizes the protection of data ownership in the process of data circulation. The data management platform manages the data which has the ownership relation with the data publisher, and effectively guarantees the data publisher's ownership to the data. In the data flow, the block chain records the network behavior information of the data users, monitors the network behavior, and ensures the data involved in the network behavior to be true and reliable. When the data user uses the target data, the target data is processed in the secure computing platform, and the processing result is returned to the data user, so as to realize the separation of the data ownership and the use right, avoid the data user to contact the data, and ensure the safety and controllability of the data circulation process.

Description

technical field [0001] The present application relates to the field of information technology, in particular to a trusted and secure data sharing system and method based on area chain technology. Background technique [0002] With the integration of information technology and human production and life, global data is characterized by explosive growth and massive accumulation. The global technological revolution is entering the era of data technology (DT) from the era of information technology (IT). Data technology has had a major impact on economic development, social governance, state management, and people's lives, and the establishment of data infrastructure is imminent. [0003] The current data infrastructure is based on the Internet. Since the Internet has evolved into a winner-takes-all ecological pattern, large companies have monopolized capital, traffic entrances, computing and storage resources, and service provision channels, resulting in users having to hand over...

AI Technical Summary

Problems solved by technology

[0003] The current data infrastructure is based on the Internet. Since the Internet has evolved into a winner-takes-all ecological structure, large companies have monopolized capital, traffic entrances, computing and storage resources, and service provision channels, resulting in users having to hand over their personal data. Large companies are exchanged for services, resulting in a situation where "data follows the application", which also makes users lose ownership of personal data, making it difficult to achieve the unification of data and value

On the other hand, there is a lack of built-in security and trusted interconnection support between information infrastructures during data circulation
