Internet of Things-Connection Redefined


 
Imagine driving home after a long day of work. En route the car instructs the residence to automatically turn on the lights, prepare a hot bath, and download the latest Netflix series.

While this may seem like a line from a SciFi script, the future is more realistic than ever. Welcome to the world of IoT or Internet of Things.

Though not as popular as its famous counterpart, Artificial Intelligence, its penetration into the consumer market is indeed extensive.


What is IoT......

It is the term used to describe a device, or set of devices which are connected to the internet, and also communicate with each other. They can share data obtained from various sensors to a central hub, analyze it using  AI, and take appropriate actions. For example, a smart thermostat can read the room temperature, analyze the same, and adjust the heating system without any human intervention. Another example would be a smart camera which provides video footage when a movement is detected in the house. This can be done remotely even when the home owner is not present.


Beginning....

The invent of this tech is heavily contested with some claims to be as early as the introduction of  first long distance communication or the electromagnetic telegraph.

Others state that IoT emerged along with the advent of Internet. The first verified device which used this technology was a Coca Cola vending machine installed at Carnegie Mellon University, 1980. It send information related to device temperature, and inventories to a central server. 

Then came the introduction of RFID (Radio Frequency Identification) tags which were used to track device location using radio waves. A point here to be noted. RFID is different from Barcode which are parallel strips containing passive information. Barcode need to be scanned independently and a line of sight to communicate. Both these drawbacks are mitigated by RFID. 

 

  

 

 

 

Another example would be Wireless Sensor Networks (WSN) which are collection of sensors placed at different location across a industrial or residential complex. They then send information periodically to a central command which are stored in real time, and actions inserted.

 

Cyber Attacks and Privacy.....

Of course, the connected world brings the concern of hacking and data theft with it. There is a remote chance that unethical actors can steal data and use the same for unscrupulous activities. What if an outside actor gets data from a smart watch. The sensitive information regarding your health such as blood pressure, allergies can then be used for manipulation. Another example would be turning on the hallway or bedroom  camera capturing private moments which can be used for ransom purpose. 

Cybersecurity for IoT devices is slowly catching up, but due to fast acceptance rate need to speed up more. Any device connected to the internet or even remotely is prone to hacking as the Stuxnet worm has proved it.

Basic steps of prevention include regular software updates, antivirus and firewall installation.

 


The Future......

The future holds great promise as the IoT industry is said to total around $2.227 billion by 2028. Also decrease in hardware and sensor costs can increase the penetration rates.

Man In The Middle Attack - EavesDropping in the Digital World

    This is a term used to describe a cyber attack where a hacker acts as middleman, during data transfer between user and an application. The app can be a financial or an E commerce website, Software as a Service (SaaS) etc. The hacker can intercept data passed via the browser to the website, and collect sensitive information such as account and credit card details, user login etc. To put it into context, it is like a postman who reads all the letters addressed to you, then reseals the same, on delivery. This way no one suspects a foul play.   Interception This is the first phase of the attack. Here the hacker establishes a connection with the target device whether a PC, Laptop or Smart phone. This is done   through various methods   like   Free WiFi  : Here a WiFi hot spot is set up  which is not password protected. When a user logs in to the network, they are in essence connecting to the hacker's system. Now any data transfer occurs via this co...

X86 vs ARM - The PC War

X86 Vs ARM A Hype?  Recently laptops powered by ARM processors have taken industry by storm. Touted as being highly power efficient, providing 18 hours backup, on as single charge. That too while running multiple program instances. Would this spell an end to the x86 architecture, where Intel and AMD rule. Or will the tables turn around? What's the Difference? Let's start with an x86 based CPU. They feature a single processing unit which can be integrated to other external peripherals like Memory, GPU etc. Here each peripheral has a separate controller, knitted together by address and data BUS. When we look at ARM all the above components (Memory, GPU) are integrated within the main chip. Known commonly as SOC (System on a Chip) . This helps in reduced footprint. But they do come with a drawback. Cannot expand by adding extra peripherals. Coming to complexity, x86 provides a simpler set up, at least for a developer. Here most of the core tasks such as Memory Read/Write, Arithmet...

The Brain within an Embedded System-Difference between Microprocessors and Microcontrollers

To understand the working of an Integrated Circuit, we need to first understand what an Embedded System is.  It is basically a conjunction of Hardware and Software parts. Embedded System is a stripped-down version of a mainstream computer, specializing in a single task. They are connected either as a standalone device, or as part of a larger electrical or mechanical system. Mainly in consumer electronics like fridges or microwaves, they have low power rating and, is economical to build. Embedded system performs complex mathematical calculations at any specific time. This is done thru a Central Processing Unit (CPU) , mostly a Microcontroller or at times, a Microprocessor. A Sensor is used to collect data from the external environment Eg: Temperature, atmospheric pressure etc. This is then fed into an Analog to Digital (ADC) converter. The digital signal thus obtained is stored in memory and, decoded by the CPU.  The output of the operation is then fed to a Digital to Analog...
