Information is one of the most valuable commodities today and in order for businesses to ensure their livelihood, it is vital for them to move from static to dynamic automated and reliable data storage models, says MARK TAYLOR, CEO of Nashua.
Information is one of the most valuable commodities. Every day, 2.5 quintillion bytes of data is created and either has a direct monetary value or can be mined for business intelligence to get a competitive edge. Data is the lifeblood of any organisation. Without the Internet and connectivity, business survival and economic growth is impossible.
The original intent of the Internet was the unrestricted flow of information in an open and shared network owned by the community. Data ownership was intended to reside with its creators in a decentralised model, free from monopolistic or centralised control.
However, large corporations quickly realised the value of tracking, storing, organising and monetising information for use in centralised services. Although not owned by a single entity, large corporations and data giants like Google support some of the most critical components of the Internet, such as search engines, web hosting, cloud computing and email services.
The case for decentralisation
As the reliance on the Internet deepens, so does the sharing of sensitive data and the need for greater privacy, data security and integrity. One proposed solution is a fully decentralised Internet independent of centralised control. This can be achieved with Blockchain technology – a decentralised and distributed ledger system that facilitates and verifies secure peer-to-peer data exchanges.
The biggest issues facing the Internet, such as net neutrality, privacy and security, pertain to issues of structure. Under a centralised model, access and convenience is offered to users at the expense of data ownership and privacy. While many service providers offer to store and safeguard data, security can’t be guaranteed. Servers can fail, networks can be hacked and privacy rights can be violated.
Decentralisation enables data and vital services to be owned by users and powered by a network of independent computers. This creates a setting much more resilient to hacks and failures as encrypted data can only be released and accessed through private keys. Decentralisation also breaks down the centralised barriers to business. With reliable high-speed Internet connectivity from Nashua, any business can access better, faster and cheaper services.
Here’s how decentralised models can revolutionise the Internet and cybersecurity.
A truly decentralised Internet is possible with Blockchain technology. Ethereum is a platform on which apps can be built and run without fraud, censorship or third-party interference. User information is encrypted and stored on the Blockchain which prevents service providers from hoarding and mining user data.
Decentralised web hosting
With only one target to hit, cybercriminals can quite easily shut down a website hosted on a centralised system. On Blockchain-based platforms, thousands of nodes or computers are employed to each serve a part of the website. This makes targeted attacks much harder and reduces hosting costs. It speeds up user access to websites by bringing cached content closer to site visitors. Self-executing smart contracts can also be used to manage resources and payments while users also have the opportunity to rent out idle network and computing resources.
Decentralised data storage
Blockchain enables users to use applications while retaining ownership of their data. By storing data on a decentralised and distributed network, the data is broken up, encrypted and stored across the Blockchain network. To access information, users need a private key to download the data from several locations at once. This not only speeds up the file access speeds but makes it increasingly difficult for cybercriminals to gain access.
Decentralised search engines
Google controls up to 95% of searches. The engine tracks search activities and has access to personal user information. Decentralised search engines store encrypted user data across a network as opposed to in a central location where it remains vulnerable. They also use open and transparent search ranking factors. This will level the playing field for businesses and content creators.
Decentralised social media
Social media platforms add significant connectivity value but at the cost of user privacy and data ownership. Decentralised social media channels will give back to users the ownership of data and reward users who choose to share information.
The full potential of a distributed economy is still unwritten but innovative solutions by emerging Blockchain innovators have already proven that the sky is the limit.
Opera launches built-in VPN on Android browser
Opera has released a new version of its mobile browser, which features a built-in virtual private network service.
Opera has released a new version of its mobile browser, Opera for Android 51, which features a built-in VPN (virtual private network) service.
A VPN allows users to create a secure connection to a public network, and is particularly useful if users are unsure of the security levels of the public networks that they use often.
The new VPN in Opera for Android 51 is free, unlimited and easy to use. When enabled, it gives users greater control of their online privacy and improves online security, especially when connecting to public Wi-Fi hotspots such as coffee shops, airports and hotels. The VPN will encrypt Internet traffic into and out of their mobile devices, which reduces the risk of malicious third parties collecting sensitive information.
“There are already more than 650 million people using VPN services globally. With Opera, any Android user can now enjoy a free and no-log service that enhances online privacy and improves security,” said Peter Wallman, SVP Opera Browser for Android.
When users enable the VPN included in Opera for Android 51, they create a private and encrypted connection between their mobile device and a remote VPN server, using strong 256-bit encryption algorithms. When enabled, the VPN hides the user’s physical location, making it difficult to track their activities on the internet.
The browser VPN service is also a no-log service, which means that the VPN servers do not log and retain any activity data, all to protect users privacy.
“Users are exposed to so many security risks when they connect to public Wi-Fi hotspots without a VPN,” said Wallman. “Enabling Opera VPN means that users makes it difficult for third parties to steal information, and users can avoid being tracked. Users no longer need to question if or how they can protect their personal information in these situations.”
According to a report by the Global World Index in 2018, the use of VPNs on mobile devices is rising. More than 42 percent of VPN users on mobile devices use VPN on a daily basis, and 35 percent of VPN users on computers use VPN daily.
The report also shows that South African VPN users said that their main reason for using a VPN service is to remain anonymous while they are online.
“Young people in particular are concerned about their online privacy as they increasingly live their lives online,” said Wallman. “Opera for Android 51 makes it easy to benefit from the security and anonymity of VPN , especially for those may not be aware of how to set these up.”
Setting up the Opera VPN is simple. Users just tap on the browser settings, go to VPN and enable the feature according to their preference. They can also select the region of their choice.
The built-in VPN is free, which means that users don’t need to download additional apps on their smartphones or pay additional fees as they would for other private VPN services. With no sign-in process, users don’t need to log in every time they want to use it.
Opera for Android is available for download in Google Play. The rollout of the new version of Opera for Android 51 will be done gradually per region.
Future of the car is here
Three new cars, with vastly different price-tags, reveal the arrival of the future of wheels, writes ARTHUR GOLDSTUCK
Just a few months ago, it was easy to argue that the car of the future was still a long way off, at least in South Africa. But a series of recent car launches have brought the high-tech vehicle to the fore in startling ways.
The Jaguar i-Pace electric vehicle (EV), BMW 330i and the Datsun Go have little in common, aside from representing an almost complete spectrum of car prices on the local market. Their tags start, respectively, at R1.7-million, R650 000 and R150 000.
Such a widely disparate trio of vehicles do not exactly come together to point to the future. Rather, they represent different futures for different segments of the market. But they also reveal what we can expect to become standard in most vehicles produced in the 2020s.
The i-Pace may be out of reach of most South Africans, but it ushers in two advances that will resonate throughout the EV market as it welcomes new and more affordable cars. It is the first electric vehicle in South Africa to beat the bugbear of range anxiety.
Unlike the pioneering “old” Nissan Leaf, which had a range of up to about 150km, and did not lend itself to long distance travel, the i-Pace has a 470km range, bringing it within shouting distance of fuel-powered vehicles. A trip from Johannesburg to Durban, for example, would need just one recharge along the way.
And that brings in the other major advance: the i-Pace is the first EV launched in South Africa together with a rapid public charging network on major routes. It also comes with a home charging kit, which means the end of filling up at petrol stations.
The Jaguar i-Pace dispels one further myth about EVs: that they don’t have much power under the hood. A test drive around Gauteng revealed not only a gutsy engine, but acceleration on a par with anything in its class, and enough horsepower to enhance the safety of almost any overtaking situation.
Specs for the Jaguar i-Pace include:
- All-wheel drive
- Twin motors with a combined 294kW and 696Nm
- 0-100km/h in 4.8s
- 90kWh Lithium-ion battery, delivering up to 470km range
- Eight-year/160 000km battery warranty
- Two-year/34 000km service intervals
