A secured parking guidance and information system (PGIS) is essential, from the management point of view to improve the efficiency of parking guidance process, and from the security point of view to guarantee the safety of vehicles in garages and parking spaces. This paper presents the design concept of a security-oriented PGIS as an application of IoT (Internet of Things) in smart city. The system architecture includes a sensor layer, communication layer, and application layer. In addition to parking slots supervision and information services, the application layer provides two import services to guarantee a high level of security: web-based user enrollment in a database and user authentication at the entrance/exit gates. The control access policy is based on biometrics (fingerprints) and deployed in a password protected wi-fi network with the use of a router’s MAC addresses whitelist. The place availability information is accessible online through a web portal for non-registered users. A scale model for tests is created to validate the smart parking guidance and information system with security concept.
