Internet of Things (IoTs) technology makes every things in physical world being digitalized and communicated with each other. The technology is emerging as a new paradigm and is expected to provide a convenient and effective life. However, for the successful realization of the IoT technologies, IoT security issues are an important prerequisite, and particularly the privacy protection is expected to become more important in view of object communication directively related with human. In this paper we describe for the security and privacy threats in IoT environment and introduce the shodan (a legitimate search engine that finds backdoor routers, switches, webcams, IoT devices connected to the Internet etc.) that can expose the security and privacy problems. Lastly, we compare the privacy threats through real-world case study of network cameras currently in use and finally derive the countermeasures for the threats.
