A smart city is an interconnection of technological components that store, process, and wirelessly transmit information to enhance the efficiency of applications and the individuals who use those applications. Over the course of the 21st century, it is expected that an overwhelming majority of the world’s population will live in urban areas and that the number of wireless devices will increase. The resulting increase in wireless data transmission means that the privacy of data will be increasingly at risk. This paper uses a holistic problem-solving approach to evaluate the security challenges posed by the technological components that make up a smart city, specifically radio frequency identification, wireless sensor networks, and Bluetooth. The holistic focus in turn permits a set of technical and ethical approaches that can combat malicious attacks and enhance data security across the networks that drive smart cities.
