Comparing Biometric and Blockchain Security Mechanisms in Smart Parking System

Abstract

In this existing era of growing urbanization and globalization, Markets are booming with smart cars and smart vehicles. The emerging shortage in vehicles parking space has created a major problem for drivers. Long search for secure parking space results in traffic jam, air pollution and waste of time. Hence it is important to park vehicle at proper parking lots. However smart parking systems enable drivers to automate and monetize them to real-time parking slot. For using these types of secure and smart parking system drivers has to disclose their sensitive and personal information. Also, existing schemes are centralized, which makes them at risk by single point of failure and restricted access this can cause problems and privacy breaches by service providers. In this paper we have compared two major mechanisms for providing security to smart parking system. Blockchain technology is distributed computing paradigm and decentralized architecture with complete trust and authentication. Whereas, biometrics system is used for authenticating user by their behavioral and physical information obtained for the purposes of both identification and access control. Comparison study of these two mechanisms assist in understanding layers of communication level and providing security to different degrees of security arrangements.
