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