Secure and Privacy-Preserving Data Computing Scheme Based on Blockchain for Double-Loop Governance of Smart Society

Abstract

Society governance nowadays has reached a new level after cutting-edge technologies such as artificial intelligence applied to every field of society. This progress requires a novel data sharing and computation mechanism among different parties as a foundation of society governance. In this paper, we introduce a new typical society governance pattern that has been emerging in the most modern cities in the world. With the involvement of smart decision-making units that change the interaction among objects in the governing process, we name the new pattern as “double-loop governing”. And to meet the higher requirement of data security and privacy protection in the process of new society governing way, we proposed a multi-party data computation and sharing scheme based on blockchain which can guarantee that every participator in the process of society governance can efficiently conduct computation based on diverse resources of data while the ownership of data can be ensured. Moreover, we introduce the architecture and the computation mechanism of the proposed scheme.
