Using Blockchain to Protect Personal Privacy in the Scenario of Online Taxi-hailing

Ning Zhang, Shan Zhong, Li Tian


Personal privacy protection issues has gradually caused widespread concern in society which will lead to economic and reputation losses, hinder network and E-commerce innovation or some other consequences if not handled properly. In this paper, we make use of the de-centralization, permanent and audibility of the blockchain to propose a blockchain-based personal privacy protection mechanism, which uses Online taxi-hailing as the application scenario. We not only provide the details of the blockchain custom transaction domain used by the scene, but also expound the information exchanging and blockchain auditing between passengers, Online taxi-hailing platform and drivers in Online taxi-hailing scene, providing a case model for the blockchain solution to personal privacy protection and a technical mechanism solution for further study of personal privacy protection issues.
