Why pressing 'upload' means losing your rights

Why pressing ‘upload’ means losing your rights

If you store your precious photos and documents online, then you may be disturbed to discover the rights you give away, says Tom Chatfield.
“The cloud” is one of my least favourite internet neologisms. It suggests something fluffy, white and weightless: a global atmosphere within which our email, social network profiles, images and shared files innocently drift. All of which sounds delightful – but the reality is that every cloud is composed of a vast infrastructure of bunker-like rooms, filled with rack upon rack of servers. And the moment you decide to upload something into this global data warehouse – be it photos of your family or precious documents – you give up many of your rights to ownership.
This summer, Apple co-founder Steve Wozniak added his voice to the chorus of those alarmed by the implications of the cloud. “I think it’s going to be horrendous. I think there are going to be horrible problems in the next five years,” he opined on a trip to Washington. “With the cloud, you don’t own anything. You already signed it away… the more we transfer everything onto the web, onto the cloud, the less we’re going to have control over it.”
Such warnings have a distinguished pedigree – and an equally impressive history of being ignored. Back in 2008, the founder of the Free Software Foundation, Richard Stallman, called the adoption of cloud-based systems “worse than stupidity… a marketing hype campaign.” So why is the world quite so willing to leap into the arms of these services if they are so dangerous? And is there anything you can do?
The overwhelming answer to the first of these questions is convenience: both for users and for companies. Having email, images, files, profiles, information and so on available wherever you go is a massive boon – and one that many users don’t associate with the idea of clouds in the first place. If you’re using any online email service, from Gmail to Outlook or Yahoo, your data is being held on the servers of the company providing that service.
Data for sale
If you’re reading a book on a Kindle, uploading any image or comment to any site you’ve signed into, tweeting or “liking” or sharing or voting or rating, you too are floating in the cloud. You just don’t know it – and that suits the people running these services just fine. The leveraging and selling of all this precious data provides the bulk of revenues for everyone from Facebook to Google.
Yet the bargain you strike by signing up to many services can easily be broken. Consider the millions of legitimate users affected when file-sharing site Megaupload was shut down by the US government in 2012 – at which point all the information in its cloud, whether pirated or not, instantly vanished from the internet. Or, this year, the Canadian company Kobo’s sudden decision to remove all self-published books from its e-books service, something to which a typical self-published author’s reaction was: “I can’t believe they have the right to do this.”
Rights – and content creators’ lack of them – lie at the heart of cloud storage’s worst dangers, something connected in turn to the underlying nature of cloud storage. In the words of Douglas Heaven, writing in New Scientist, “a digital file exists as a state of matter… rather than matter itself.” Your information is not a piece of property in any legal sense. It’s merely the electrical state of a disk owned by somebody else; or, more likely, the state of a large number of different disks scattered across the world, each containing part or all of what may be numerous copies of your information, backed up and accessed and reproduced as necessary to ensure server-side efficiency.
The moment you hit upload, you’ve given away almost every right you might expect to possess over what’s “yours”. Instead, the entitlements and obligations you’re left with will be spelled out in the terms of an almost-certainly-unread licensing agreement with the company who own a service – and who, in most cases, will award themselves the ability to do pretty much anything legal they see fit with your material. 
Depending on the country that a company’s servers are located in, moreover, a government will also reserve certain privileges regarding your information: looking inside your old emails without a warrant, perhaps, in the case of US; or locking you up for insulting the monarch in Thailand.

Outside the cloud
So is there an alternative to life in the cloud? Julian Ranger, chairman and founder of the young tech company SocialSafe, believes there could be. SocialSafe is a company founded on the belief that the dire warnings about cloud technologies really are true. In Ranger’s words, “lack of privacy through inadvertent self-harm (over-sharing) and through third-party data aggregation will cause greater and greater harm over the years as people cannot leave their past behind them” – and that’s before you get onto data loss, theft, fraud, and the wholesale shutting down of online services.
The service SocialSafe currently offers is the automatic copying of all your cloud content to your own computer – to be held by you no matter what happens online, and browsed or analysed at your own convenience. The service covers the gamut of social media, from Twitter to Facebook via Instagram and LinkedIn. But by the end of next year, it plans to cover categories of data ranging from purchase histories and utility bills to financial and health data – and, Ranger hopes, towards an eventual model where you yourself own your personal data library, and can “decide to make it available in parts you decide, for purposes you agree with.”
Meanwhile, legal thinking on digital rights is slowly catching up with the absurdity of their being almost no current recourse for loss, deletion or the whims of a service provider; but its pace is massively exceeded by the rate at which material is flowing online, into the hands of businesses whose profitability rests on owning and exploiting everything you give them.
Companies like SocialSafe are intriguing, in this context, thanks to their insistence that precisely the opposite should be true: personal data should be something you control, on a computer that’s in your possession – and companies wishing to offer their services should come to you seeking access.

'Legitimate' Bitcoin's value soars after Senate hearing



'Legitimate' Bitcoin's value soars after Senate hearing

A bitcoinThe US Senate will hear that Bitcoin has the same benefits and risks as other online-payment methods

The value of virtual currency Bitcoin has soared to over $900 (£559), after a US Senate committee hearing.
The committee was told that virtual currencies were a "legitimate financial service" with the same benefits and risks as other online payment systems.
The Homeland Security and Governmental Affairs Committee is exploring the "promises and risks" of Bitcoin for "government and society at large".
The currency has more than trebled in value since October.
Fear and confusion
The US Senate hearing was prompted by the closure of the Silk Road website in October. The site, which sold drugs and other illegal goods, was shut down by the FBI.
Users of the site were required to pay for their transactions using bitcoins.
Representatives from the Department of Justice and financial regulator the Securities and Exchange Commission have been asked to provide their views about virtual currencies to the committee and submissions have been received from the FBI and the US Federal Reserve.

"Virtual currencies, perhaps most notably Bitcoin, have captured the imagination of some, struck fear among others, and confused the heck out of the rest of us," the chair of the committee, Senator Thomas Carper, said in opening remarks.
The FBI, in a letter to the committee released on Sunday, said that it recognised virtual currencies offered "legitimate financial services" but they could be "exploited by malicious actors".
Mythili Raman, the head of the Justice Department's Criminal Division, told the committee: "We have seen increasing use of such currencies by drug dealers, traffickers of child pornography, and perpetrators of large-scale fraud schemes."
Mainstream acceptance
Jerry Brito, senior research fellow at George Mason University told Bloomberg: ''Two years ago it was alarm when Silk Road first came on the scene.
''Since then, Congress has been educating itself and understands that there are great potential benefits, and like any new technology there are going to be some challenges. But they see there is a balance to be struck here and they are generally positive on the technology," he said.

HOW BITCOINS WORK

Bitcoin is often referred to as a new kind of currency.
But it may be best to think of its units being virtual tokens rather than physical coins or notes.
However, like all currencies its value is determined by how much people are willing to exchange it for.
To process Bitcoin transactions, a procedure called "mining" must take place, which involves a computer solving a difficult mathematical problem with a 64-digit solution.
For each problem solved, one block of bitcoins is processed. In addition the miner is rewarded with new bitcoins.
This provides an incentive for people to provide computer processing power to solve the problems.
To compensate for the growing power of computer chips, the difficulty of the puzzles is adjusted to ensure a steady stream of about 3,600 new bitcoins a day.
There are currently about 11 million bitcoins in existence.
To receive a bitcoin a user must have a Bitcoin address - a string of 27-34 letters and numbers - which acts as a kind of virtual postbox to and from which the bitcoins are sent.
Since there is no registry of these addresses, people can use them to protect their anonymity when making a transaction.
These addresses are in turn stored in Bitcoin wallets which are used to manage savings.
They operate like privately run bank accounts - with the proviso that if the data is lost, so are the bitcoins owned.
Trade in Bitcoin is small compared with that in countries' official currencies. But since its creation in 2008, Bitcoin has become a popular way to pay for things online. There are currently more than 12 million bitcoins in existence according to Bitcoincharts, a website that provides financial information about the currency.
On one exchange site, Mt. Gox, the value of the currency rose to $900 (£559) on Monday before falling back to $727 (£452). This compares with a price of $200 (£124) in late October.
The closing down of Silk Road and hearings in front of US government committees have led some to believe that prices are increasing as investors think Bitcoin will gain more mainstream acceptance.
"Lots of factors are driving the price action in Bitcoin, including pure speculation," said Garrick Hileman, an economic historian at the London School of Economics.
"Regulatory interest in Bitcoin also traditionally has a positive effect on the price of Bitcoin," he added.
Jan Lambregts, head of financial market research at Rabobank, which does not trade in Bitcoin, said regulators were right to get involved.
"Looking at it from a distance, it very much looks like it could be a speculative bubble. It's a small market, with a lot of interest in it, which is inflating and distorting the price," he said.
"But you can see the concerns for governments - this is a currency outside their normal domain and which is not influenced by central banks.
"It may all be relatively small-scale now, but decisions taken now could have wider repercussions were such virtual currency experiments to be expanded in the future," he added.
Some have questioned whether trading in Bitcoin is insufficiently transparent and therefore easier to use for illegitimate means. Patrick Murck, from the Bitcoin Foundation, which promotes the use of the currency, told the BBC that the network was very open and everybody could see every transaction that happened.
"I would challenge that it's for illegitimate use or bad actions. What we're finding is not that it's a haven for illegitimate activities but that there are many legitimate uses," he said.
Whatever people are using Bitcoin for, Mr Brito thinks it's here to stay.
"These hearings mean Bitcoin is finally coming into its own," he said.
"It's a real thing and it's not going anywhere and these hearings highlight that."

Building computer brains that can reason like humans

FUTURE THINKING

Building computer brains that can reason like humans

What if a computer chip could think – and react – just like a human? IBM’s Cognitive Computing Group believes such a breakthrough is just around the corner.
Computing has developed at an amazing pace over the last few decades, but even today’s computers are essentially glorified calculators, says Dr Dharmendra Modha. The founder of IBM’s Cognitive Computing Group wants to change that. He wants our computers to think more like humans.
Modha and his team are designing a cognitive computing chip and software ecosystem inspired by the human brain. It would consume far less power and space than today’s computers and could power everything from search and rescue robots in hazardous environments to intelligent buoys which float on ocean waves, predicting tsunamis or warning of oil pollution.
The idea, part of the Defense Advanced Research Projects Agency(Darpa) project called SyNAPSE, involves a global team of experts working across neuroscience, nanoscience and supercomputing to build this complicated system. Modha spoke to BBC Future at his laboratory in Almaden, California about how this approach could change the way our computers see the world.

Teaching children code


Related Stories

These days coders are as in demand as supermodels were in the 1980s.
From banks to hospitals to local government, everyone wants a techie on their team.
But just as more and more jobs rely on computing and coding, so conversely fewer people have the skills to fill them.
To head off a global coding crisis, something needs to be done to persuade youngsters that there is more to coding than dark rooms, pizzas and unsociable hours.
Robot friends
For Vikas Gupta, former head of consumer payments at Google, the answer lies in starting them early.
"I have a daughter aged two and I wanted to do something for children. I started to wonder at what age children can grasp coding concepts," he told the BBC.
Children as young a five are able to grasp coding concepts as long as the learning is done through tangible interactions, according to an MIT study that Mr Gupta came across.
Play-i robots Can Bo and Yana inspire young children to code?
"That was eye-opening for me. And there were no products that exist for that age. So I set out to design something that a child younger than 10 can have fun with and learn programming," he said.
He came up with Bo and Yana, two robots that aim to teach children about programming without them even realising it.
Yana is the smaller robot and can be programmed to make sounds and perform actions.
Bo can be programmed to move around and the robots interact with each other.
"They can be programmed to play hide-and-seek," said Mr Gupta.
Initially children just start by playing a variety of games with the robot, barely aware that they are coding.
Once they have got the hang of that, they can move on to use visual programs such as Scratch to create their own code.
Both robots are controlled wirelessly via a tablet or smartphone - currently the app is only available for iOS devices.
The project is crowdfunded and hit its $250,000 target within three days.
The plan is to start selling the robots in the summer of next year.
Mr Gupta is also keen to get the robots into schools and is working to develop curriculum resources for them.
Tech education
As part of his research, Mr Gupta was shocked at the state of technology education in the US.
"Computer science education has got worse in the last 20 years rather than better," he said.
A 2010 report from the Computer Science Teachers Association seems to bear this out.
It found that more than two-thirds of US states had little or no computer science standards at secondary school level.
There was also "deep and widespread confusion" about what technology education should consist of, whether it be computer literacy or computer science.
The report concluded that the US had "fallen woefully behind in preparing students with the fundamental computer science knowledge and skills they need for future success".
Coding from day one

It could draw some valuable lessons from Estonia.
The Eastern European country may only be small - its population is just 1.3 million - but with an envied e-government programme and the birthplace of some big-name tech firms including Skype, it is definitely punching above its weight when it comes to technology.
The president - who himself turned his hands to a bit of coding to fund himself through university - is very clear about where he wants to see education go.
He has the backing of Education Minister Jaak Aaviksoo, a former physicist, who wants to drag the educational system into the computer age.
"It is time for 19th Century educational methods to rise the challenges of the 21st Century," he tells the BBC.
As part of that he has introduced coding into the classroom as soon as children start school, aged seven.
"Kids are very capable and they are already doing complicated things on their tablets and smartphones. If they are used to that then there shouldn't be a gap when they start school.
"School should not be an old-style kind of place but it should build on the potential kids are bringing from home," he adds.
Currently the initiative is being tested but Mr Aaviksoo hopes to roll it out to all primary schools in the next five years.
And Estonia's radical education plans don't stop with coding for seven-year-olds.
Quadratic equations
Children in a maths lesson Do maths lessons need an overhaul?
In February it announced a partnership with Oxford-based computerbasedmaths.org, a group that aims to radically overhaul the way maths is taught in schools.
For British technologist Conrad Wolfram, who founded the group, there is little point in teaching children to make complicated calculations, when they get a computer to do that, and maths should be used more creatively to solve problems that really interest them.
While learning times tables and other basic calculations are necessary in the early years, by the time children get to secondary school, he thinks that the emphasis on complex computations is both unnecessary and likely to turn pupils off the subject.
"It is not dumbing it down, it is making it harder. It also makes it a lot more fun, more geared towards problems that you might want to solve," he told the BBC.
So instead of lessons on quadratic equations, a computer-based maths class would focus on real-world problem-solving, posing questions such as "Am I normal?", "What makes a beautiful shape?" or "Do I need to insure my laptop?"
Estonia is testing the system in 30 of its secondary schools.
"The idea is to use maths as a tool box to solve problems," said Mr Aaviksoo.
He is also considering the idea of letting children bring their own devices to school.
"So many have tablets and other things, although there would have to be provision for those that don't," he said.
New language
In England and Wales, the ICT curriculum is about to be ripped up and replaced by one that Education Minister Michael Gove hopes will both interest young people more and prepare them better for the computer-dominated world of work.
There will be less emphasis on spreadsheets, more hands-on developing and definitely a return to good old-fashioned coding.
For his part, Mr Wolfram thinks that Mr Gove's plans need to go a lot further - and he could start by ripping up the current maths curriculum as well.
"It's great to have coding back on the agenda but I think that coding should be tied to primary school maths," he said.
He doesn't think that such change will happen overnight - in fact he estimates that the changes in the curriculum to reflect the computer age will take 25 years to bed in, but he is hopeful that, in the end, it can create students that are more confident in using the language of coding.
