Internet of things: A survey on privacy and securityfor smart homes

Internet of Things (IoT) is a domain that targets at creating a smart world by linking various physical and virtual
devices and enabling an interaction amongst them. IoT works by collecting data from various sources and processes
them to provide certain useful information for various serviceswith or without human intervention. The automated
information exchange between two devices in IoT, takes place through some specific communication technologies
such as Wireless Sensor Networks (WSN) and Radio Frequency Identification (RFID). IoT has numerous
applications [3][11] such as the information and communication industry has been impacted by IoT and there has
been a transformation through fantastic opportunities brought by IoT. Consumer related activities have seen a major
development through IoT. IoT has many potential applications in prevention of natural disasters like earthquake and
forest fires, monitoring the conditions and vibrations in buildings and provides warning regarding these. IoT can be
used in warning the consumers regarding the expiry date of products,on the presence of any allergic ingredients and
other options in accordance to user’s preference. IoT can be highly efficient and useful in creating a smart home by
monitoring the consumption of water, energy and other resources and to conserve the same. Home security system,
signalling the necessity to switch off electrical appliances are some applications offered by IoT , to the home
environment. One of the major uses/applications of IoT is in the monitoring the patients in hospitals and old age
homes. As far as the environment is concerned, devices that monitor temperature levels in water bodies and the
environment can be used in detecting the high levels of global warming [3]. In addition to all the benefits of IoT , it
is important to consider the different layers of security and privacy concerns that are to be addressed.[6]
