Using network IoT technologies, the emergence of telemedicine may be handled. It is limited with regard to data transfer, the advancement of telecom technology, and newly developed communication protocols based on Internet of Things technology. In this paper, we examine and summarize the different IoT security and privacy issues related to telemedicine. We also introduce general security and privacy implementation, telecommunication networks, security and privacy aspects, and future directions for telemedicine. This paper outlines many mutual protocol norms and problems, as well as security and privacy considerations for telemedicine. Governments are now searching for new technology since the need for telemedicine has outpaced industry capability. Even if some scholars have examined the technology in the context of several concerns, the peripheral developments in IoT technology and protocol standards are highlighted. Additionally, prospective uses for telemedicine across a range of fields have been presented for the future.
