This open letter sent out by World Wide Web inventor Tim Berners-Lee on 12 March 2017 calls on Internet users to stand up to fake news, loss of privacy and unethical advertising.
Today marks 28 years since I submitted my original proposal for the world wide web. I imagined the web as an open platform that would allow everyone, everywhere to share information, access opportunities and collaborate across geographic and cultural boundaries. In many ways, the web has lived up to this vision, though it has been a recurring battle to keep it open. But over the past 12 months, I’ve become increasingly worried about three new trends, which I believe we must tackle in order for the web to fulfill its true potential as a tool which serves all of humanity.
1) We’ve lost control of our personal data
The current business model for many websites offers free content in exchange for personal data. Many of us agree to this – albeit often by accepting long and confusing terms and conditions documents – but fundamentally we do not mind some information being collected in exchange for free services. But, we’re missing a trick. As our data is then held in proprietary silos, out of sight to us, we lose out on the benefits we could realise if we had direct control over this data, and chose when and with whom to share it What’s more, we often do not have any way of feeding back to companies what data we’d rather not share – especially with third parties – the T&Cs are all or nothing.
This widespread data collection by companies also has other impacts. Through collaboration with – or coercion of – companies, governmentsare also increasingly watching our every move online, and passing extreme laws that trample on our rights to privacy. In repressive regimes, it’s easy to see the harm that can be caused – bloggers came arrested or killed, and political opponents can be monitored. But even in countries where we believe governments have citizens’ best interests at heart, watching everyone, all the time is simply going too far. It creates a chilling effect on free speech and stops the web from being used as a space to explore important topics, like sensitive health issues, sexuality or religion.
2) It’s too easy for misinformation to spread on the web
Today, most people find news and information on the web through just a handful of social media sites and search engines. These sites make more money when we click on the links they show us. And, they choose what to show us based on algorithms which learn from our personal data that they are constantly harvesting. The net result is that these sites show us content they think we’ll click on – meaning that misinformation, or ‘fake news’, which is surprising, shocking, or designed to appeal to our biases can spread like wildfire. And through the use of data science and armies of bots, those with bad intentions can game the system to spread misinformation for financial or political gain.
3) Political advertising online needs transparency and understanding
Political advertising online has rapidly become a sophisticated industry. The fact that most people get their information from just a few platforms and the increasing sophistication of algorithms drawingupon rich pools of personal data, means that political campaigns are now building individual adverts targeted directly at users. One source suggests that in the 2016 US election, as many as 50,000 variations of
adverts were being served every single day on Facebook, a near-impossible situation to monitor. And there are suggestions that some political adverts – in the US and around the world – are being used in unethical ways – to point voters to fake news sites, for instance, or to keep others away from the polls. Targeted advertising allows a campaign to say completely different, possibly conflicting things to different groups. Is that democratic?
These are complex problems, and the solutions will not be simple. But a few broad paths to progress are already clear. We must work together with web companies to strike a balance that puts a fair level of data
control back in the hands of people, including the development of new technology like personal “data pods” if needed and exploring alternative revenue models like subscriptions and micropayments. We
must fight against government over-reach in surveillance laws, including through the courts if necessary. We must push back against misinformation by encouraging gatekeepers such as Google and Facebook
to continue their efforts to combat the problem, while avoiding the creation of any central bodies to decide what is “true” or not. We need more algorithmic transparency to understand how important decisions that affect our lives are being made, and perhaps a set of common principles to be followed. We urgently need to close the “internet blind spot” in the regulation of political campaigning.
Our team at the Web Foundation will be working on many of these issues as part of our new five year strategy – researching the problems in more detail, coming up with proactive policy solutions and bringing together coalitions to drive progress towards a web that gives equal power and opportunity to all. I urge you to support our work however you can – by spreading the word, keeping up pressure on companies an governments or by making a donation. We’ve also compiled a directory of other digital rights organisations around the world for you to explore and consider supporting too.
I may have invented the web, but all of you have helped to create what it is today. All the blogs, posts, tweets, photos, videos, applications, web pages and more represent the contributions of millions of you around the world building our online community. All kinds of people have helped, from politicians fighting to keep the web open, standards organisations like W3C enhancing the power, accessibility and security of the technology, and people who haveprotested in the streets. In the past year, we have seen Nigerians stand up to a social media bill that would have hampered free expression online, popular outcry and protests at regional internet shutdowns in Cameroon and great public support for net neutrality in both India and the European Union.
It has taken all of us to build the web we have, and now it is up to all of us to build the web we want – for everyone. If you would like to be more involved, then do join our mailing list, do contribute to us, do join or donate to any of the organisations which are working on these issues around the world.
– Sir Tim Berners-Lee

Money talks and electronic gaming evolves
Computer gaming has evolved dramatically in the last two years, as it follows the money, writes ARTHUR GOLDSTUCK in the second of a two-part series.
The clue that gaming has become big business in South Africa was delivered by a non-gaming brand. When Comic Con, an American popular culture convention that has become a mecca for comics enthusiasts, was hosted in South Arica for the first time last month, it used gaming as the major drawcard. More than 45 000 people attended.
The event and its attendance was expected to be a major dampener for the annual rAge gaming expo, which took place just weeks later. Instead, rAge saw only a marginal fall in visitor numbers. No less than 34 000 people descended on the Ticketpro Dome for the chaos of cosplay, LAN gaming, virtual reality, board gaming and new video games.
It proved not only that there was room for more than one major gaming event, but also that a massive market exists for the sector in South Africa. And with a large market, one also found numerous gaming niches that either emerged afresh or will keep going over the years. One of these, LAN (for Local Area Network) gaming, which sees hordes of players camping out at the venue for three days to play each other on elaborate computer rigs, was back as strong as ever at rAge.
MWeb provided an 8Gbps line to the expo, to connect all these gamers, and recorded 120TB in downloads and 15Tb in uploads – a total that would have used up the entire country’s bandwidth a few years ago.
“LANs are supposed to be a thing of the past, yet we buck the trend each year,” says Michael James, senior project manager and owner of rAge. “It is more of a spectacle than a simple LAN, so I can understand.”
New phenomena, often associated with the flavour of the moment, also emerge every year.
“Fortnite is a good example this year of how we evolve,” says James. “It’s a crazy huge phenomenon and nobody was servicing the demand from a tournament point of view. So rAge and Xbox created a casual LAN tournament that anyone could enter and win a prize. I think the top 10 people got something each round.”

Blockchain is generally associated with Bitcoin and other cryptocurrencies, but these are just the tip of the iceberg, says ESET Southern Africa.
This technology was originally conceived in 1991, when Stuart Haber and W. Scott Stornetta described their first work on a chain of cryptographically secured blocks, but only gained notoriety in 2008, when it became popular with the arrival of Bitcoin. It is currently gaining demand in other commercial applications and its annual growth is expected to reach 51% by 2022 in numerous markets, such as those of financial institutions and the Internet of Things (IoT), according to MarketWatch.
What is blockchain?
A blockchain is a unique, consensual record that is distributed over multiple network nodes. In the case of cryptocurrencies, think of it as the accounting ledger where each transaction is recorded.
A blockchain transaction is complex and can be difficult to understand if you delve into the inner details of how it works, but the basic idea is simple to follow.
Each block stores:
– A number of valid records or transactions.
– Information referring to that block.
– A link to the previous block and next block through the hash of each block—a unique code that can be thought of as the block’s fingerprint.
Accordingly, each block has a specific and immovable place within the chain, since each block contains information from the hash of the previous block. The entire chain is stored in each network node that makes up the blockchain, so an exact copy of the chain is stored in all network participants.
As new records are created, they are first verified and validated by the network nodes and then added to a new block that is linked to the chain.
How is blockchain so secure?
Being a distributed technology in which each network node stores an exact copy of the chain, the availability of the information is guaranteed at all times. So if an attacker wanted to cause a denial-of-service attack, they would have to annul all network nodes since it only takes one node to be operative for the information to be available.
Besides that, since each record is consensual, and all nodes contain the same information, it is almost impossible to alter it, ensuring its integrity. If an attacker wanted to modify the information in a blockchain, they would have to modify the entire chain in at least 51% of the nodes.
In blockchain, data is distributed across all network nodes. With no central node, all participate equally, storing, and validating all information. It is a very powerful tool for transmitting and storing information in a reliable way; a decentralised model in which the information belongs to us, since we do not need a company to provide the service.
What else can blockchain be used for?
Essentially, blockchain can be used to store any type of information that must be kept intact and remain available in a secure, decentralised and cheaper way than through intermediaries. Moreover, since the information stored is encrypted, its confidentiality can be guaranteed, as only those who have the encryption key can access it.
Use of blockchain in healthcare
Health records could be consolidated and stored in blockchain, for instance. This would mean that the medical history of each patient would be safe and, at the same time, available to each doctor authorised, regardless of the health centre where the patient was treated. Even the pharmaceutical industry could use this technology to verify medicines and prevent counterfeiting.
Use of blockchain for documents
Blockchain would also be very useful for managing digital assets and documentation. Up to now, the problem with digital is that everything is easy to copy, but Blockchain allows you to record purchases, deeds, documents, or any other type of online asset without them being falsified.
Other blockchain uses
This technology could also revolutionise the Internet of Things (IoT) market where the challenge lies in the millions of devices connected to the internet that must be managed by the supplier companies. In a few years’ time, the centralised model won’t be able to support so many devices, not to mention the fact that many of these are not secure enough. With blockchain, devices can communicate through the network directly, safely, and reliably with no need for intermediaries.
Blockchain allows you to verify, validate, track, and store all types of information, from digital certificates, democratic voting systems, logistics and messaging services, to intelligent contracts and, of course, money and financial transactions.
Without doubt, blockchain has turned the immutable and decentralized layer the internet has always dreamed about into a reality. This technology takes reliance out of the equation and replaces it with mathematical fact.
