The connection of common physical objects, devices, and systems using the technology of internet is known as Internet of Things (IoT) and it represents a paradigm shift in technology. These items may autonomously collect and share data among themselves and with centralised systems in an IoT environment because they are outfitted with sensors, software, and communication capabilities. This is all done without the need for human intervention. The Internet of Things (IoT) widely used in smart cities to gather and share massive amounts of data in order to uplift urban living. However, ensuring the privacy and the security of this data is paramount.
