A Data Sharing and Access Control Model Based on Blockchain

Abstract

In the era of data-centric driving enterprise business, how to effectively control data access and securely share data between enterprises has become a common concern. While blockchain's distributed ledger solves this problem in some ways, blockchain's asymmetric encryption is only for one-to-one secure transmissions. Therefore, this paper uses attribute-based encryption to propose a data sharing and access control model for enterprise data. Designed to achieve more precise access control and secure sharing. After comparison, the model can better solve the problem of data access control within enterprises and data sharing between enterprises.
