Dark Trade in the Dark Web
Dark Trade in the Dark Web
Imagine the onion which has many layers. Similarly, the internet too have many layers. The top of these layers is called as surface web where our day to day searches on the internet takes place. Mostly, we get the results that are indexed by the popular search engines like Google, Bing and Yahoo.
Beneath the surface web, there comes a layer called Deep web where the contents are not indexed by search engines.
The information related to governments, banks, finance institutions, scientific research data, academic information etc. will be found in the deep web and all those are heavily encrypted and cannot be accessed easily by ordinary people as it requires permission.
When we go all the way to the bottom, there we see Deep web where the users can communicate with encrypted messages and can buy or sell anything with total anonymity. There's no separate place called dark web. It is just a part of the internet. All it hides the people's identity and location. That's it. In order to utilize dark web, we need dark net software such as Tor.
Dark web is not a new buzzword. Its infrastructure was built back in 1970. It was created for the US Navy to protect their officer's identity when they maneuver through the internet without being recognized or traced. Unlike other browsers which register the IP address while searching, the Tor browser sends the user's request via multiple proxy servers located around the world along with the encryption. So that no one smells where the request comes from. All the dark websites have weird domain names and ends with .onion suffix. This makes those sites very difficult to track and can only be accessed through Tor browser.
Some of the black markets used in Dark web are Silk Road, Dream, Agora, Alphabay - all providing illegal services such as selling weapons, guns, drugs etc. In reality, the dark web is not that much dark. People want to use it for accessing many good sites dark web offers while protecting their privacy. Some good websites such as - The Hidden wiki which is a dark web wikkipedia and Blackbook which is a dark web facebook can be found in this dark web. The slowness can be experienced while browsing because of the subsequent routing between several proxies. Definitely, I would say the dark web is safe until we keep our personal details hidden. Care must be taken not to wander much inside the dark web.

REMOTE WORK IS ON RISE
The COVID-19 pandemic followed by the lock down all around the world has led the people to work from home where many companies have adopted this model and is expected to shoot up in future. As of March 2020, the video conferencing company the Zoom acquired a userbase of 10 million daily users - now leveraged to 200 million active users. Despite the recent security issues, the Zoom has incorporated some measures such as password enabled meeting, end-to-end encryption etc. and formed such a massive userbase.
BIG DATA BROUGHT BIG RESULTS IN WORLD CUP TO GERMANY
Germans won the world cup in 1990 with the Germanic style footballing. After 24 years, in 2014, they bagged world cup. But, this time with the much help of Big Data. The native SAP analytics conducted a survey on 2010 world cup and they found that each player hold the ball at their feet for 4.3 seconds in an average. Spain won the world cup in 2010. On analyzing the precision maps, heat maps and other statistical based insights, SAP advised the German national team to reduce the time of holding the ball by each player and pass the ball to others to get the goal faster. The results were remarkable. 4.3 seconds went down to 1.1 seconds on an average. With this improvement, they knocked down Brazilian team by 7-1 and then claimed the world cup. This is how they effectively reduces the time of possession and got big results.
Emergence of 5G technology going to reshape the world
5G is a next generation wireless technology that uses wide variety of spectrum bands including millimeter wave (mmWave) radio spectrum, which can carry large amounts of data over a short distance (high throughput). 5G not only interconnects people but also the machines, smart devices altogether. Hence, it will be used more in IoT devices. It supports high speed data communications as a result we can watch any movies without streaming, download HD movies within 10 seconds - the same task would take 10 minutes using 4G. Virtual reality and augmented reality based projects use 5G more. A recent test conducted by Verizon where they transmitted video content through 5G network and the latency was just 1.5 milliseconds which is unnoticeable by us. Ericsson predicted by 2023, 30 billion smart devices and 20 billion IoT devices connect through 5G network. Due to its high speed data transfer and low latency, the driver-less cars can use this technology more.
