IoT is composed of tiny objects implanted with sensors, actuators and Radio Frequency Identification (RFID) tags which make the best use of the network to offer an extensive choice of applications. The major cause for the rapid expansion of IoT is the economic range of intelligent objects and easy availability of internet services. The sensitive information is accessible over network and thus creating threat to data and information. The information privacy is a critical factor in the growth of IoT. In this paper, we review the basics of privacy in IoT, various issues related to privacy and the technologies which can aid in maintain the security of personal data.
