What is LIFI?

Li-Fi (light fidelity) is the wireless communication technology, which use light to transmit data. The term Li-Fi was first introduced by Harald Has in the year 2011, the Li-Fi was first introduced in March 2011 by digital communication industry.
The physical range of Li-Fi is visible light spectrum ultraviolet and infrared radiation, the Li-Fi is the light communication system which is capable of transmitting data at high speeds over the visible light, ultraviolet and infrared spectrum's. The technology is similar to Wi-Fi but the key difference is that the Wi-Fi uses radio frequency to transmit data where as Li-Fi uses light to transmit data, most notably the Li-Fi has wider bandwidth and has ability to safely function in the areas which are susceptible to electromagnetic interference such areas are airport cabins, military, hospital.

 Will it replace WiFi in the near future?

The Li-Fi technology offers higher transmission speed, it's is a derivative of optical wireless communication (OWC) which uses light from light emitting diodes ( LEDs) as a medium to deliver network. The federal communications commission has warned of potential spectrum crises because Wi-Fi is close to full capacity, where as Li-Fi has almost no limitations on capacity, the visible light spectrum is 10,000 times larger than the entire radio frequency spectrum.
In October 2013, it was reported that Chinese manufacturers were working on Li-Fi development kit, later in April 2014 the Russian company stubs Coman announced the development of a Li-Fi wireless local network called Beam Caster the current module of transfer data is at 1.25 GB/s, but they foresee boosting speed up to 5 GB/s in the future.

Over the past six months, comapny has detected high levels of activity by stealers in Europe and Asia. The use of malware designed to harvest consumers’ digital data—known as password stealers – has seen a significant rise in 2019. Password Stealing Ware (PSW) is a major weapon in the cybercriminals’ toolkit to sabotage users’ privacy. This malicious type of software grabs data directly from users’ web browsers using various methods.  Quite often, this information is sensitive and includes access details for online accounts as well as financial information—like saved passwords, autofill data and saved payment card details.  In addition, some families of this type of malware are designed to steal browser cookies, user files from a specific location as well as app files, such as messenger services. Modern consumers are increasingly active online and rely on the internet to carry out many tasks in their daily lives. This fills their digital profiles with more and more dat

Not all of these sites are run by criminals. who live under depressive regimes, security conscious agencies and companies, and individuals very concerned about privacy also use tor, freenet and the invisible internet project. The internet dark web isn't actually not that big. Media accounts frequently overestimate the size of the ark web by pumping in everything that's not accessible by search engines. That also includes corporate intranets and password protected sites like online forums, bank website and email platform. Sonatypes crown jewel is its database of description of over 1.2 million open source package. If that is lost, it could be an existential outcome. Said Wayne Jackson, CEO of the Fulton, Maryland based software supply chain management company. To shut down any such leak quickly , sonatypes monitors the web for any ind

In most cases, the submerged
