You’re not that private!

Images, locations and health issues are just some of the bits of data that are sent to the cloud – sometimes out of our control. But, have you wondered who has access to this data? VINCE RESENTE of Intel explores these issues an how we can address them.

You’re watching your son play a school soccer match. Your camera is ready when he scores the winning goal, taking his team to victory. You’re so proud; you can’t wait to share the news. Along with the picture, you write: “The goal that made Sunny Hills Primary School winners today; well done, Peter!”

A few hours later, you get this message: “I saw Peter’s goal for Sunny Hills – amazing! I was on the other side; you have to see this angle.” You probably won’t think twice about clicking on the link in the message – obviously the person sending the message was there, how else would he know your son’s name, his school and that he scored the winning goal?

Two months later, you can’t understand why you’ve been blacklisted and the bank won’t grant you a personal loan.

Hackers are using social engineering methods such as these, which prey on our willingness to share our lives online, to access our personal information. They trick us into following links that give them access to our phones, which these days store everything from our social media profiles, which are always logged in, to our GPS apps that have our home addresses already saved. It’s become almost too easy to steal someone’s identity.

IoT?

With the rise of the Internet of Things (IoT), we’ll soon be sending a lot more personal information to the cloud. Wearable devices that monitor our heart rates, blood pressure and glucose levels are becoming as common as regular wristwatches, while apps like Waze and Foursquare let anyone know where we are – and when we’re not at home, which is practically an invitation to burglars.

Where is all this information going and who has access to it? At the moment, too many people.

I don’t mind if my doctor can see my health data, but I have a problem with my medical insurance company using it to hike my premiums because my heart rate never goes past resting. And I certainly don’t want hackers getting their hands on it.

By default, our IoT DNA should be locked down in a virtual vault for which only we have the password. Only we should decide who can access what information – like an opt-in system – and block access to everyone else.

But passwords are inherently insecure, especially when we use the same one for multiple accounts. Anti-virus software and firewalls don’t offer sufficient protection as they’re easily breached and rely on users to regularly update them.

My eyes only

Everyone in the value chain has a responsibility to protect users’ information, from the users themselves and device manufacturers, to software creators and security providers.

We’re already seeing promising developments in the security industry. Soon, our faces or fingerprints will be our passwords, while password repositories will store passwords for the sites we use most often, and will only allow us to access those sites once we’ve supplied a ‘master’ password.

Device manufacturers and software vendors are also addressing flaws in existing security systems. Intel Security (previously known as McAfee), for example, is no longer just concerned with viruses and firewalls. It now checks multiple entries for infiltration and records common patterns. Anything out of the ordinary – if your computer pings every other PC on the network, for example – will get blocked and reported.

Soon we won’t need anti-virus software because the processor will be doing the smart thinking to flag suspicious behaviour. Every PC will be equipped with a software appliance that will operate as the firewall instead of having to load software onto an operating system.

In the past, we could walk the streets at night and not continually look over our shoulders. Today, we jump at every sound and take precautions to protect ourselves. We’ve adapted to changes in our physical security; we need to apply that same vigilance to cyber security.

Android Go puts reliable smartphones in budget pockets

Nokia, Vodacom and Huawei have all launched entry-level smartphones running the Android Go edition, and all deliver a smooth experience, writes BRYAN TURNER.

Three new and notable Android Go smartphones have recently hit the market, namely the Nokia 1, the Vodafone Smart Kicka 4 and the Huawei Y3 (2018). These phones run one of the most basic versions of Android while still delivering a fairly smooth user experience.

Historically, consumers purchasing smartphones in the budget bracket would have a hit-and-miss experience with processing speed, smoothness of user interface, and app stability. The Google-supported Android Go edition operating system optimises the user experience by stripping out non-important visual effects to speed up the phone. Thish allows for more memory to be used by apps. 

Google also ensures that all smartphones running Android Go will receive feature and security updates as they are released by Google. This is a major selling point for these smartphones, as users of this smartphone will always be running the latest software, with virtually no manufacturer bloatware.

Vodafone Smart Kicka 4

At the lowest entry-level, the Vodafone Smart Kicka 4 performs well as a communicator for emails and WhatsApp messages. The 4” screen represents a step up for entry-level Android phones, which were previously standardised at 3.5”.

The display is bright and very responsive, while the limited screen real estate leaves the navigation keys off the screen as touch buttons. It uses 3G connectivity, which might seem like an outdated technology, but is good enough to stream SD videos and music. Vodacom has also thrown in some data gifts if the smartphone is activated before the end of September 2018. 

Its camera functionalities might be a slight let down for the aspirant Instagrammer, with a 2MP rear flash camera and a 0.3MP selfie snapper. Speed wise, the keyboard pops up quickly, which is a huge improvement from the Smart Kicka 3. However, this phone will not play well with graphics-intensive games. 

Nokia 1

Next up is the Nokia 1, which adds a much better 5MP camera, improved battery life and a bigger 4.5” screen. It supports LTE, which allows this smartphone to download and upload at the speed of flagships. It also sports the Nokia brand name, which many consumers trust.

Although the front camera is 2MP, the quality is extremely grainy, even with good lighting. This disqualifies this smartphone for the social media selfie snapper, but the 5MP rear camera will work for the landscape and portrait photographer. 

The screen also redeems this smartphone, providing a display which represents colours truly and has great viewing angles. Xpress-on back covers allows the use of interchangeable, multi-coloured back covers, which has proven to be a successful sales point for mid-range smartphones in the past. 

Huawei Y3 (2018)

The most capable of the Android Go edition competitors, the Huawei Y3 (2018) packs an even bigger screen at 5”, as well as an improved 8MP rear camera and HD video recording. The screen is the brightest and most vibrant of the three smartphones, but seems to be calibrated to show colours a little more saturated than they actually are. 

Nevertheless, the camera outperforms the other smartphones with good colour replication and great selfie capabilities via the 2MP front camera – far superior to the Nokia 1 despite the same spec. LTE also comes standard with this smartphone and Vodacom throws in 4G/LTE data goodies until the end of September 2018. The battery, however, is not removable and may only be replaced by a warranty technician.

Comparing the 3

All three smartphones have removable back covers, which provide access to the battery, SIM card and SD card slots. The smartphones have Micro USB ports on the bottom with headphone jacks on the top. The built-in speakers all performed well, with the Y3 (2018) housing an exceptionally loud built-in speaker. 

Although all at different price points, all three phones remain similar in performance and speed. The differentiators are apparent in the components, like camera quality and screen quality. It would be fair to rank the quality of the camera and battery life by respective market prices. The Vodafone Smart Kicka 4 performed well, for its R399 retail price. The Nokia 1, on the other hand, lags quite a bit in features when compared to the Huawei Y3 (2018), bwith oth retailing at R999.

SA gets digital archive

As the world entered the centenary of Nelson Mandela’s birth on Mandela Day, 18 July 2018, South Africa celebrated the launch of a digital living archive.

The southafrica.co.za  site carries content about the country’s collective heritage in South Africa’s eleven official languages.

Designed as a nation building,  educational and brand promotion web based tool, the free-to-view platform features award-winning photographic and written content by leading South African photographers, authors, academics and photojournalists.

The emphasis is on quality, credible, factual content that celebrates a collective heritage in terms of the following: Cultural Heritage; Natural Heritage; Education; History; Agriculture; Industry; Mining; and Travel.

At the same time as reflecting on the nation’s history, southafrica.co.za celebrates South Africa’s natural, cultural and economic assets so that the youth can learn about their nation in their home language.

Southafrica.co.za Founder and CEO Hans Gerrizen conceptualised southafrica.co.za as a means for youth and communities from outlying areas to benefit from the digital age in terms of the web tool’s empowering educational component.

“We can only stand to deepen our collective experience of democracy and become a more forward planning nation if we know facts about our nation’s past and present in everyone’s home language,” he says.

Southafrica.co.za, with sister company Siyabona Africa, is the organiser and sponsor of the Mandela: 100 Moments photographic exhibition that runs until 30 September at Cape Town’s V&A Waterfront-based Nelson Mandela Gateway to Robben Island.  The 3-month exhibition, which runs daily from 08h00 until 15h00, is showcasing one hundred iconic Nelson Mandela images taken by veteran South African photojournalist and self-taught lensman Peter Magubane.
