Esp32 - Micro Controller Redefined


 

When it comes to ioT (Internet of things) applications, there are number of micro controllers that provide salient features. One of them being ESP32 module, developed by Espressif Systems.

This micro controller has low power consumption and, is economical by cost. Some of the main features include

  • Integrated WiFi and Bluetooth
  • Uses RISC-V (Reduced Instruction Set Computer)
  • Has single and dual core variant
  • Can connect additional modules, like camera for image recognition
But what makes it really stand out, is its integration to TensorFlow lite.  Yes, this chip is able to house AI capabilities. Coding is done via Arduino development environment. 

TensorFlow in an open source neural software library, used in Machine learning. Developed by Google Brain, AI models can be trained in the field of Image Recognition, Natural Language Recognition (NLP) etc. Coding environment is primarily Python. TensorFlow lite is a mini version which can run locally on smaller devices.  This reduces the need to connect to the cloud.

An example would be a fire alarm system where, sensor records temperature changes in the vicinity. Using pre learned AI model, the micro controller then initiates an alert, based on set parameters. 

To start experimenting with ESP32, various development boards are available. Do check the link below

Virtual Private Network (VPN) - Browsing Anonymous

  Privacy is a major concern when browsing the internet. Your data could be eavesdropped by hackers, companies targeting ads or even rogue state actors. What gets revealed would be personal browsing history, location monitoring, IP addresses to name a few. Enter the tech... Virtual Private Network or simply known as VPN is a technology used to prevent unauthorized access of your private data. Even if a hacker penetrates the network and get hold of data packets, all that is revealed is gibberish.  This is because all the information that passes through your device is encrypted and can be only revealed through a personal key.  Internet Service Provider Before going further, a knowledge of Internet Service Provider (ISP) is needed. They are the backbone of the World Wide Web. ISP provides each device with a unique IP (Internet Protocol) address, bandwidth allocation and network security. When a website is searched, first it goes from your device to the Router or Modem which...

Cyber stalking cases has reportedly gone high in recent years.  Stalking is considered as any form of unwanted attention, contact or harassment directed towards an individual. This results in victim's personal space being encroached or taken for granted.  The preparator perform stalking through fake profiles, monitoring social media sites, messages or chat history. They initiate a volley of hate speech or try to tarnish their victim's reputation. Here stalking can be also a form of love addiction. An unrequited love can cause the stalker to perform the above steps as an act of revenge. Mode of Operation Installing a piece of code in the victim's computer for accessing the webcam. The spyware comes bundled with a software which could be do...

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...
