Hiding your data in plain sight

Filed under: Liberty, Media, Technology — Tags: , , , , , — Nicholas @ 09:12

Ronald Bailey gathers up some resources you might want to investigate if you’d prefer not to have the NSA or other government agencies watching your online activities:

First, consider not putting so much stuff out there in the first place. Wuergler devised a program he calls Stalker that can siphon off nearly all of your digital information to put together an amazingly complete portrait of your life and pretty much find out where you are at all times. Use Facebook if you must, but realize you’re making it easy for the government to track and find you when they choose to do so.

A second step toward increased privacy is to use a browser like DuckDuckGo, which does not collect the sort of information — say, your IP address — that can identify you with your Internet searches. Thus, if the government bangs on their doors to find out what you’ve been up to, DuckDuckGo has nothing to hand over. I have decided to make DuckDuckGo my default for general browsing, turning to Google only for items such as breaking news and scholarly articles. (Presumably, the NSA would be able to tap into my searches on DuckDuckGo in real time.)

Third, TOR offers free software and a network of relays that can shield your location from prying eyes. TOR operates by bouncing your emails and files around the Internet through encrypted relays. Anyone intercepting your message once it exits a TOR relay cannot trace it back to your computer and your physical location. TOR is used by dissidents and journalists around the world. On the downside, in my experience it operates more slowly than, say, Google.

Fourth, there is encryption. An intriguing one-stop encryption solution is Silent Circle. Developed by Phil Zimmerman, the inventor of the Pretty Good Privacy encryption system, Silent Circle enables users to encrypt their text messages, video, and phone calls, as well as their emails. Zimmerman and his colleagues claim that they, or anyone else, cannot decrypt our messages across their network, period. As Wuergler warned, this security doesn’t come free. Silent Circle charges $10 per month for its encryption services.

However, your mobile phone is a beacon that can’t be easily masked or hidden:

Now for some bad news. Telephone metadata of the sort the NSA acquired from Verizon is hard — read: impossible — to hide. As the ACLU’s Soghoian notes, you can’t violate the laws of physics: In order to connect your mobile phone, the phone company necessarily needs to know where you are located. Of course, you can avoid being tracked through your cell phone by removing its batteries (unless you have an iPhone), but once you slot it back in, there you are.

Federal government denies collecting electronic data on Canadians

Filed under: Cancon, Government, Media, Technology — Tags: , , , , , — Nicholas @ 08:55

Oh, well, if the government denies doing something I guess they pretty much have to be telling the truth, right? Unfortunately, the photo accompanying this Toronto Star article doesn’t show if Peter MacKay is crossing the fingers on his left hand:

The Conservative government flatly denies Canadian spy agencies are conducting any unauthorized electronic snooping operations.

After facing questions from the NDP Opposition about how far he has authorized Ottawa’s top secret eavesdropping spy agency to go, a terse Conservative Defence Minister Peter MacKay left the Commons, telling the Star: “We don’t target Canadians, okay.”

A former Liberal solicitor general says that doesn’t mean other allied spy agencies don’t collect information on Canadians and share it with the Canadian spying establishment.

Liberal MP Wayne Easter, who was minister responsible for the spy agency CSIS in 2002-03, told the Star that in the post-9/11 era a decade ago it was common for Canada’s allies to pass on information about Canadians that they were authorized to gather but Ottawa wasn’t.

The practice was, in effect, a back-door way for sensitive national security information to be shared, not with the government, but Communications Security Establishment Canada (CSEC) and, if necessary, the Canadian Security Intelligence Service (CSIS).

CSEC is a new bit of alphabet soup in the public sphere … I’d never heard of the organization until yesterday. Tonda MacCharles explains what the agency is empowered to do:

The CSEC, an agency that is rarely in the public eye, has far-reaching national security powers to monitor and map electronic communication signals around the globe.

It is forbidden by law to target or direct its spying on Canadians regardless of their location anywhere in the world, or at any person in Canada regardless of their nationality.

The National Defence Act says CSE may, however, unintentionally intercept Canadians’ communications, but must protect their privacy in the use and retention of such “intercepted information.” The agency’s “use” of the information is also restricted to cases where it is “essential to international affairs, defence or security.”

CSEC’s job is to aid federal law enforcement and security agencies, including the military, in highly sensitive operations. It was a key component of Canadian operations in Afghanistan, for example.

No surprise here – there’s also a maple-flavoured PRISM

Filed under: Cancon, Government, Media — Tags: , , , , , — Nicholas @ 11:05

In the Globe and Mail, Colin Freeze covers the Canadian data collection program that was approved by the Martin government in 2005 and “renewed” by the Harper government in 2011:

Defence Minister Peter MacKay approved a secret electronic eavesdropping program that scours global telephone records and Internet data trails — including those of Canadians — for patterns of suspicious activity.

Mr. MacKay signed a ministerial directive formally renewing the government’s “metadata” surveillance program on Nov. 21, 2011, according to records obtained by The Globe and Mail. The program had been placed on a lengthy hiatus, according to the documents, after a federal watchdog agency raised concerns that it could lead to warrantless surveillance of Canadians.

There is little public information about the program, which is the subject of Access to Information requests that have returned hundreds of pages of records, with many passages blacked out on grounds of national security.

It was first explicitly approved in a secret decree signed in 2005 by Bill Graham, defence minister in Paul Martin’s Liberal government.

It is illegal for most Western espionage agencies to spy on their citizens without judicial authorization. But rising fears about foreign terrorist networks, coupled with the explosion of digital communications, have shifted the mandates of secretive electronic-eavesdropping agencies that were created by military bureaucracies to spy on Soviet states during the Cold War.

The Canadian surveillance program is operated by the Communications Security Establishment Canada (CSEC), an arm of the Department of National Defence.

Original author of the Patriot Act decries its current abuse

Filed under: Government, Law, Liberty, Media, USA — Tags: , , , , — Nicholas @ 10:20

In the Guardian, Jim Sensenbrenner demands to see the current misuse of the Patriot Act brought to an end:

Last week, the Guardian reported that the Obama administration is collecting records of every call made to, from or within the US, as well as records of many digital communications. President Obama has tried to deflect criticism by claiming “every member of Congress has been briefed on this program.” While some members of Congress were briefed — particularly those on the intelligence committees — most, including myself, were not.

The administration claims authority to sift through details of our private lives because the Patriot Act says that it can. I disagree. I authored the Patriot Act, and this is an abuse of that law.

I was the chairman of the House judiciary committee when the US was attacked on 11 September 2001. Five days later, the Justice Department delivered its proposal for new legislation. Although I, along with every other American, knew we had to strengthen our ability to combat those targeting our country, this version went too far. I believed then and now that we can defend our country and our liberty at the same time.

[. . .]

In his press conference on Friday, President Obama described the massive collection of phone and digital records as “two programs that were originally authorized by Congress, have been repeatedly authorized by Congress”. But Congress has never specifically authorized these programs, and the Patriot Act was never intended to allow the daily spying the Obama administration is conducting.

To obtain a business records order like the one the administration obtained, the Patriot Act requires the government to prove to a special federal court, known as a Fisa court, that it is complying with specific guidelines set by the attorney general and that the information sought is relevant to an authorized investigation. Intentionally targeting US citizens is prohibited.

Technically, the administration’s actions were lawful insofar as they were done pursuant to an order from the Fisa court. But based on the scope of the released order, both the administration and the Fisa court are relying on an unbounded interpretation of the act that Congress never intended.

QotD: Whistleblowers

Filed under: Government, Media, Quotations, USA — Tags: , , , , — Nicholas @ 09:36

The U.S. government is on a secrecy binge. It overclassifies more information than ever. And we learn, again and again, that our government regularly classifies things not because they need to be secret, but because their release would be embarrassing.

Knowing how the government spies on us is important. Not only because so much of it is illegal — or, to be as charitable as possible, based on novel interpretations of the law — but because we have a right to know. Democracy requires an informed citizenry in order to function properly, and transparency and accountability are essential parts of that. That means knowing what our government is doing to us, in our name. That means knowing that the government is operating within the constraints of the law. Otherwise, we’re living in a police state.

We need whistle-blowers.

Leaking information without getting caught is difficult. It’s almost impossible to maintain privacy in the Internet Age. The WikiLeaks platform seems to have been secure — Bradley Manning was caught not because of a technological flaw, but because someone he trusted betrayed him — but the U.S. government seems to have successfully destroyed it as a platform. None of the spin-offs have risen to become viable yet. The New Yorker recently unveiled its Strongbox platform for leaking material, which is still new but looks good. This link contains the best advice on how to leak information to the press via phone, email, or the post office. The National Whistleblowers Center has a page on national-security whistle-blowers and their rights.

Don’t put too much faith in denials from Verizon and other companies…

Filed under: Business, Government, Law, Liberty, Technology — Tags: , , , , , — Nicholas @ 10:10

As Mic Wright points out, the companies named in the Prism leaks may not be acting as free agents:

Pastor Niemoller’s “First they came…” poem is over-quoted but with good reason. It is far too easy to be complacent. Addicted and reliant as many of us are on free web services, it’s more convenient to just accept the companies outright denials that they have been complicit with the NSA’s programme. But look closely at those statements and things become rather less clear, as Michael Arrington pointed out.

The tech industry’s denials have been carefully drafted and similarly worded. It is not unfeasible to imagine that those companies have turned over users’ personal information to the NSA in another fashion. Facebook founder and CEO Mark Zuckerberg’s statement was one of the strongest: “Facebook is not and has never been part of any program to give the US or any other government direct access to our servers. We have never received a blanket request or court order from any government agency asking for information…”

Zuckerberg’s words are reassuring until you consider that any company that receives an order under the Foreign Intelligence Surveillance Act Amendments Act — the legislation the Obama administration is using to justify the broad surveillance — is forbidden from disclosing they have received it or disclosing any information about it. It’s not surprising that no mea culpas have emerged from major tech firms or that Palantir — the big data surveillance company with the $5 billion valuation and CIA funding — denies any connection with the project. The NSA has been a Palantir client and one of the company’s co-founders, billionaire investor Peter Thiel, also sits on Facebook’s board.

Feingold was right, back in 2001

Filed under: Government, Liberty, USA — Tags: , , , , , — Nicholas @ 09:42

Former US senator Russ Feingold was the only member of the senate to vote against the original Patriot Act:

He took a stand against the legislation because it increased the federal government’s authority exponentially and didn’t require enough judicial oversight.

Now here we are more than a decade later and it has been revealed that the U.S. government has been collecting massive amounts of data on millions of Americans every single day, using provisions found in the Patriot Act as justification.

Through the secret “PRISM” surveillance program and court orders compelling at least Verizon to provide records on all its customers, the FBI and NSA have enjoyed access to unthinkable amounts of Americans’ data, all without ever informing the public of alarming domestic surveillance.

In his address on the Senate floor in 2001, Former Sen. Feingold seemingly warned the U.S. about the exact thing so many Americans are outraged over today.

[. . .]

“In 2001, I first voted against the PATRIOT Act because much of it was simply an FBI wish list that included provisions allowing our government to go on fishing expeditions that collect information on virtually anyone,” the statement read. “Today’s report indicates that the government could be using FISA in an indiscriminate way that does not balance our legitimate concerns of national security with the necessity to preserve our fundamental civil rights.”

“This is deeply troubling. I hope today’s news will renew a serious conversation about how to protect the country while ensuring that the rights of law-abiding Americans are not violated,” he added.

CRTC rule changes may finally signal the end of the three-year phone contract

Filed under: Business, Cancon, Technology — Tags: , , — Nicholas @ 10:54

In Maclean’s, Steve Rennie outlines the new cell phone rules to come into effect later this year:

Wireless customers will be able to cancel their cellphone contracts after two years without any penalties — even if they’ve signed up for longer terms — under a new set of rules unveiled Monday by the federal telecom regulator.

However, the Canadian Radio-television and Telecommunications Commission didn’t go as far as an outright ban on the three-year contracts that Canadians vented so much about earlier this year as the national code for wireless services was being drafted.

“We didn’t focus on the length of the contract, we focused on the economic relation,” CRTC chairman Jean-Pierre Blais said in an interview.

“So, in effect, it’s equivalent to those asking for a ban of three-year contract without us actually banning three-year contracts, because what we’re saying is the contract’s amortization period can only be for a maximum period of 24 months.”

There’s also good news for those who travel with their cell phones (that’d be pretty much every Canadian traveller these days):

The CRTC is also capping extra data charges at $50 per month and international data roaming charges at $100 per month to avoid huge, surprise bills.

The regulator will require providers to allow customers to unlock their devices after 90 days, or immediately if they pay the full amount of the device.

Could this be the long-hoped-for breakthrough in battery technology?

Filed under: Science, Technology — Tags: , , , , — Nicholas @ 10:40

In The Register, Tony Smith discusses a new prototype battery that might be coming to your electronic devices … eventually:

Electronics continue to shrink to ever smaller sizes, but researchers are having a tough time miniaturising the batteries powering today’s mobile gadgets. Step forward, bicontinuous nanoporous electrodes.

Smartphones use smaller power packs than they did five years ago, it’s true, but that’s because their chips and radios are more power efficient, not because of any major new battery technology.

Now boffins from the University of Illinois at Urbana-Champaign reckon they have come up with a new pocket-friendly electricity supply.

Enter the “microbattery”, a compact power cell constructed from many three-dimensional nanoporous electrodes capable, its developers claim, of delivering both high power and a large energy capacity.

The negative cathode was devised by another team at the university, but graduate student James Pikul, working under Bliss Professor of mechanical science and engineering William King, figured out how to create a compatible anode and put the two into a battery.

[. . .]

The cathode design, devised by a team led by the University’s Professor Paul Braun, is fast charging. Pikul reckons building a battery out of it yields a rechargeable that can be filled up in a thousandth of the time it takes to charge a comparably sized regular rechargeable cell.

Building a battery in a lab is one thing. Working out how to manufacture it commercially at a price that makes it a realistic power source for future devices is another thing altogether. Pikul and King will be working on that next.

Good news and bad news about border searches of your electronic devices

Filed under: Bureaucracy, Liberty, USA — Tags: , , , , , — Nicholas @ 11:32

Declan McCullagh on the mixed news from a recent court ruling:

U.S. customs officials must have a reasonable justification before snatching your laptop at the border and scanning through all your files for incriminating data, a federal appeals court ruled today.

The Ninth Circuit Court of Appeals ruled that Homeland Security’s border agents must have “reasonable suspicion” before they can legally conduct a forensics examination of laptops, mobile phones, camera memory cards, and so on.

Today’s opinion is a limited — but hardly complete — rejection of the Obama administration’s claim that any American entering the country may have his or her electronic files minutely examined for evidence of criminal activity. Homeland Security has said the electronic border searches could detect terrorists, drug smugglers, and people violating “copyright or trademark laws.”

For your “protection”, some new smartphones are configured to hide “mature” content

Filed under: Britain, Business, Media, Technology — Tags: , , , , , — Nicholas @ 09:52

Willard Foxton discusses some eye-raising configurations on new smartphones in the UK:

When you get a new phone, there’s a very good chance it comes with automatic filters enabled. For example, it’s very common for you have to explicitly request the ability to call premium-rate phone lines. This is long established, but now, a sinister new trend has started, whereby phone providers are automatically blocking access to certain websites for “mature content”, rather than “adult content”.

Mobile provider 3UK is blocking access to political satire as “mature content”; Orange is preventing access to feminist articles as “mature content” through its automatically applied Orange Safeguard service; several providers are blocking perfectly legitimate sites like Pink News because they deal with gay issues, or Channel 4’s excellent Embarrassing Bodies website, because of the graphic discussion of body parts and sexuality.

This was bad enough when these services were blocking porn (I for one wholeheartedly support the right of teenagers to watch smut on their iPhones), but now it seems overzealous providers are blocking access to anything a Catholic Bishop might consider for adults only. This carries not only the problem of “overblocking” caused by lazy filter design — notably, it’s hard to get your website read if it refers to Middlesex or Scunthorpe — but also as these filters are automatically applied, most people don’t even realise they are losing access to certain parts of the web.

Polls are less accurate thanks to a 9% response rate (and falling)

Filed under: Media, Politics — Tags: , , , — Nicholas @ 10:41

Iowahawk has been posting a daily Twitter update reminding people that the reliability of political polls is much lower than ever before:

At Macleans, Colby Cosh digs a bit deeper to find out how polling organizations are responding to their approaching-flatline response rate:

The boffins are becoming increasingly reliant on “non-probability samples” like internet panel groups, which give only narrow pictures of biased subsets of the overall population. The good news is that they can take many such pictures and use modern computational techniques to combine them and make pretty decent population inferences. “Obama is at 90 per cent with black voters in Shelbyville; 54 per cent among auto workers; 48 per cent among California epileptics; 62 per cent with people whose surnames start with the letter Z…” Pile up enough subsets of this sort, combined with knowledge of their relative sizes and other characteristics, and you can build models which let you guess at the characteristics of the entire electorate (or, if you’re doing market research, the consumerate).

As a matter of truth in advertising, however, pollsters have concluded that they shouldn’t report the uncertainty of these guesses by using the traditional term “margin of error.” There is an extra layer of inference involved in the new techniques: they offer what one might call a “margin of error, given that the modelling assumptions are correct.” And there’s a philosophical problem, too. The new techniques are founded on what is called a “Bayesian” basis, meaning that sample data must be combined explicitly with a prior state of knowledge to derive both estimates of particular quantities and the uncertainty surrounding them.

[. . .]

Pollsters are trying very hard to appear as transparent and up-front about their methods as they were in the landline era. When it comes to communicating with journalists, who are by and large a gang of rampaging innumerates, I don’t really see much hope for this; polling firms may not want their methods to be some sort of mysterious “black box,” but the nuances of Bayesian multilevel modelling, even to fairly intense stat hobbyists, might as well be buried in about a mile of cognitive concrete. Our best hope is likely to be the advent of meta-analysts like (he said through tightly gritted teeth) Nate Silver, who are watching and evaluating polling agencies according to their past performance. That is, pretty much exactly as if they were “black boxes.” In the meantime, you will want to be on the lookout for that phrase “credibility interval.” As the American Association for Public Opinion Research says, it is, in effect, a “[news] consumer beware” reminder.

A timely reminder that economic statistics only paint part of the overall picture

Filed under: Economics, Technology — Tags: , , — Nicholas @ 10:52

Tim Worstall at the Adam Smith Insitute blog:

Almost at random from my RSS feed two little bits of information that tell of the quite astonishing economic changes going on around us at present. The first, that the world is now pretty much wired:

    According to new figures published by the International Telecommunications Union on Thursday, the global population has purchased 6 billion cellphone subscriptions.

Note that this is not phones, this is actual subscriptions. It’s not quite everyone because there are 7 billion humans and there’s always the occasional Italain with two phones, one for the wife and one for the mistress. But in a manner that has never before been true almost all of the population of the planet are in theory at least able to speak to any one other member of that population. The second:

    The most recent CTIA data, obtained by All Things D, shows that US carriers handled 1.16 trillion megabytes of data between July 2011 and June 2012, up 104 percent from the 568 billion megabytes used between July 2010 and June 2011.

Within that explosive growth of basic communications we’re also seeing the smartphone sector boom. Indeed, I’ve seen figures that suggest that over half of new activations are now smartphones, capable of fully interacting with the internet.

One matter to point to is how fast this all is. It really is only 30 odd years: from mobile telephony being the preserve of the rich with a car battery to power it to something that the rural peasant of India or China is more likely to own than not. Trickle down economics might have a bad reputation but trickle down technology certainly seems to work.

Finland and the dangers of being a company town

Filed under: Business, Economics, Europe — Tags: , , , , , — Nicholas @ 09:09

I had no idea that Finland’s economy was so tightly tied to the fortunes of Nokia:

Nokia contributed a quarter of Finnish growth from 1998 to 2007, according to figures from the Research Institute of the Finnish Economy (ETLA). Over the same period, the mobile-phone manufacturer’s spending on research and development made up 30% of the country’s total, and it generated nearly a fifth of Finland’s exports. In the decade to 2007, Nokia was sometimes paying as much as 23% of all Finnish corporation tax. No wonder that a decline in its fortunes — Nokia’s share price has fallen by 90% since 2007, thanks partly to Apple’s ascent — has clouded Finland’s outlook.

[. . .]

Strip these sorts of firms from the list and only one resembles Nokia: Taiwan’s Hon Hai, an electronics manufacturer. Yet Nokia made 27% of Finnish patent applications last year; the corresponding figure for Hon Hai was 8%. Although numbers are falling, Finland is home to the greatest number of Nokia employees; Hon Hai’s staff is mostly in China. It is a similar story with other firms. Sales of Nestlé, a consumer-goods company, weigh in at 15% of Swiss GDP but its share of Swiss jobs is punier than Nokia’s in Finland. Samsung, whose revenues are twice Nokia’s, has half its clout as a share of GDP: South Korea’s economy is more diversified. The importance of Nokia to Finland looks like a one-off.

Smartphone swordfight: what could possibly go wrong?

Filed under: Technology — Tags: , , — Nicholas @ 08:06

Jacob Siegal reports on a new (but not publicly available) smartphone app:

FAR can accurately determine the distance between two smartphones by measuring the time it takes for one sound emitted from one phone to reach the speaker of another.

The first implementation of FAR is an application called SwordFight, which is exactly what it sounds like. Two smartphone owners stand across from each other, jabbing at each other’s phones in order to score a hit. A player has to strike within 15 centimeters to score, causing the other player to lose a point. Using FAR, along with the accelerometer and digital compass, the phones not only keep track of their distance from one another, but can determine which player is attacking, and which player has been struck.

Microsoft is dubbing this subgenre of gaming Mobile Motion Games, and it can only be accomplished with the supreme accuracy of the FAR sound-ranging scheme. Considering the mass hysteria in the gaming world surrounding motion devices, this project does not come as much of a surprise. Nonetheless, I still desperately want to wave an imaginary sword around for a few minutes and know for sure who won.
