A Blockchain-Based Privacy Preserving Ticketing Service

Abstract

This study proposes a privacy preserving Blockchain-Based Ticketing Service (BB Tickets), which stores information about events and related tickets in the blockchain network. As the blockchain technologies can ensure information integrity, ticket buyers can use the data stored in the blockchain network to ensure the authenticity of the purchased tickets and to resolve related disputes. Furthermore, the Non-Interactive Zero-Knowledge (NIZK) scheme is utilized in the proposed system to protect user privacy. Therefore, this study contributes to providing a privacy-preserving means for users to enjoy the reliable ticketing service provided by the blockchain technologies.
