A Blockchain-Based Privacy Protection Application for Logistics Big Data

Abstract

Logistics business is generally managed by logistics orders in plain text, and there is a risk of disclosure of customer privacy information in every business link. In order to solve the problem of privacy protection in logistics big data systems, a new kind of logistics user privacy data protection scheme is proposed. First of all, an access rights management mechanism is designed by combining blockchain and anonymous authentication to realize the control and management of users’ access rights to private data. Then, the privacy and confidentiality protection between different services is realized by dividing and storing the data of different services. Finally, the participants of the intra-chain private data are specified by embedding fields in the logistics information. The blockchain node receiving the transaction is used as the transit node to synchronize the intra-chain privacy data, so as to improve the intra-chain privacy protection within the business. Experimental results show that the proposed method can satisfy the privacy requirements and ensure considerable performance.
