Abstract	This work presents a complex privacy-preserving solution based on attribute-based credentials and smart contract techniques for emerging parking services in city zones. Our system provides the full set of privacy-enhancing features such as anonymity, untraceability, and unlinkability of user parking registrations. Thanks to that it prevents the city and service providers from profiling and tracking the users (e.g., their movement). Furthermore, we involved smart contracts and the underlying decentralized Blockchain technology in payment and verification phases to prevent the presence of a single point of failure in those processes which can endanger the system's security and availability. We provide the full cryptographic specification of the system, its security analysis, and the implementation results in this paper. © 2021 ACM.
