Current devices that could be used in your dwellingToday, in this contemporary world we are surrounded by gadgets, these are all applications ofembedded systems, development of which in the last decade has led to burgeoning small hand-helddevices which can again be connected to each other to synchronize data and share information withinternet.All these devices and equipment which are made to make our life easy are all together as asystem known as internet of things.These devices have penetrated the very depth of our livelihood and with the advent ofapplications which can be installed and run on the OS on these devices, same devices hence now canbe used for multiple different applications. Let’s consider an example of a most common hand-helddevice a smart phone, its used to make a phone call to sending text, browsing internet, downloadingand listening to our favorites genre, this device can also record our heartbeats, if used in conjunctionwith other portable equipment it can detect and measure diabetes in a person. A simple iPhone is alsobeing used to monitor activity during gym exercises etc.The climate control system in every house is another such IoT device, it uses data from localprobes into its systems and decides the room temperature accordingly so that a person entering thehouse won’t feel an impulse. The data used to take a decision can also be taken from localmeteorological department or a national system in case of some natural calamity like a cyclone, heatwave etc.Similarly, light control systems are also trends in present day homes, they are good for savingon energy bills, the bill reduces to half of what it used to be prior to installing the feature. This canalso be attached to ambience control or TV control, water motor control, ex- the motor will not run onits own when there is no one inside the house, and/or fills the tank partially when there are a fewpeople inside the house.Home security system is another such device used widely, people can control remotely oreven locally while living in their respective homes as to who can access or get into their house, thisgenerally has a camera, microphone and a remote to open the gates which opens when it gets therequired signal. In an advanced person, automatic door lockers and a security key is featured, whichthen may dial the local law enforcement agency in case the system senses breach in the security.Home security system is augmented by latest in development like motion sensors, infra-red detectors,and suspicious activity detector.Advanced fire detection also features in the above-mentioned system which works on thelogic that if 5 or more smoke and fire detectors detect fire, then the system automatically relays a
message to the owner and also to the local fire department, hospitals for the emergency and also thelaw enforcement agencies.Smart TVs are also a trend today, this offers you access to internet for streaming through youtube videos apart from setting reminder to your favorite shows and also recording live streams for youto watch later. Theses also have mood detection feature which then reads your face and plays a movieor a serial based on it. Smart TVs may also feature motion sensors to understand your body languageand offer gesture based services, the motion or movement it captures is stored locally and can beunderstood as your digital gesture or a digital id based on your body language.These systems are there to make out life easier, they are connected with each other tounderstand our requirements even better and hence the quality of service increases, but there systemshave a set of disadvantages as well. Let’s discuss some of these issues and possibly think of somesolutions.Usage, control, connectivity, security, privacyAs the human life has become easier, they try to become lethargic, this has lead to a downfallof the fitness culture among the youth. Dependence on these technologies should be for the benefit,here off course the disadvantages depends on the usage, over usage of any technology can be a bane.Now let’s see some serious implications miss use or abuse of these IoT devices. Since almostall of these artificially intelligent IoTs store human behavioral data, these are vulnerable to securitythreats like thefts, blackmailing, misuse etc. A possible solution to such an issue would be securingthe data both physically and through a firewall with the most updated form of data security protocolsavailable in the market. This security issue is serious in nature and will have to be innovative in ourapproach; a data security designer should always be a step ahead of schemers. As we know that a signal which is predictable and can be controlled is used, any other signalwhich cannot be predicted and/or controlled is of no use to engineers. Hence there is an issue withcontrol of these IoT devices; this section also takes care of the security aspect of the data. The basicunit or a black box as we may say is a processing device which takes a set of input and provides a setof output after processing. The data moving in and moving out of the blackbox has to be controlled.The data has to be controlled, and the device needs to be always in our control. Consider- an examplewhere an anonymous person has control or remote access of our security system or even cameras inauto drawing hall can be a nightmare. Hence this feature has to be controlled. Here again anappropriate firewall needs to be in place in order to control.Reliability has to do with many terms like repeatability; robustness etc. repeatability is gettingthe same set of results or solutions for a set of input data, no matter how many times it is applied.
