Internet of Things (IoT) is a term that refers to a global network of physical and virtual 'things' that are connected to the internet. Each object has a unique identifier that is used to identify it. IoT is a new technology that will fundamentally alter how we interact with devices. Almost every electronic device in the future will be a smart device capable of computing and communicating with other hand-held and infrastructure devices. Since the majority of devices are battery-powered, security and privacy are major concerns in the IoT. Authentication, identification, and heterogeneity of devices are the primary security and privacy issues on the Internet of Things. Integration, scalability, ethical communication mechanisms, business models, and surveillance are all significant challenges. A qualitative method is used in this study to collect data from a semi-structured interview about privacy and security concerns on the Internet of Things from the perspective of some developers. In the results, the impact of IoT, as well as the privacy and security challenges and issues inherent in IoT were discussed
