We talk a lot about privacy on the net nowadays. Some claim that privacy is dead, and you just have to cope with it. Some are slightly less pessimistic. But all agree that our new cyber-society will redefine and reduce what we once knew as personal privacy.
The privacy threat is not monolithic. There are actually many different kinds of privacy threats and they are sometimes mixed up. So let’s set this straight and have a look at the three major classes of privacy.
This is about controlling what data you share with your family, spouse, friends, colleagues etc. Tools for doing this are passwords on web accounts, computers and mobile devices, as well as your privacy settings in Facebook and other social media.
This is the fundamental level of privacy that most of us are aware of already. When this kind of privacy is discussed, it is usually about Facebook privacy settings and how to protect your on-line accounts against hackers. Yes, protection against hacking is actually a sort of privacy issue too.
Who knows most about your life? You, your spouse or Facebook? Chances are that the service providers you use have the most comprehensive profile on you. At least if we only count data that is stored in an organized and searchable way. This profile may be a lot wider than what you have shared yourself. Google knows what you Google for and your surfing habits are tracked and blended into the profile. The big data companies also try to include as much as possible of your non-digital life. Credit card data, for example, is low-hanging fruit that tells a lot about us.
But what exactly are they doing with that data? It’s said that if you aren’t paying for the product, then you ARE the product. The multitude of free services on the net is made possible by business models that utilize the huge database. Marketing on the service provider’s own page is the first step. Then they sell data to other marketing companies or run embedded marketing. And it gets scary when they start to sell data to other companies too. Like someone who consider employing you or who need to figure out if you’re a high-risk insurance customer.
The main problem with provider privacy is that there aren’t any simple tools to guard you. The service provider can use data in their systems freely no matter what kind of password you use to keep outsiders out. The only way to master this is to control what data they get on you, and your own behavior is what matters here. But it is hard to live a normal cyber-life and fight the big-data companies. I have posted some advice about Facebook and plan to come back to other aspects of the issue in later posts.
The security and privacy of Internet is to a large extent enforced by legislation and trust, not by technical methods like encryption. But don’t expect the law to protect you if you do a crime. Authorities can break your privacy if there is a justified need for it. This can be a good compromise that guards both our privacy and security, as long as the authorities are trustworthy.
But what happens if they aren’t? Transparency and control are after all things that make the work harder for authorities, so they don’t like it. And a big threat, like terrorism for example, can easily be misused to expand their powers far beyond what’s reasonable. Authority privacy really becomes an issue when the working mode changes from requesting data on selected targets to siphoning up a broad stream of data and storing it for future use. There has been plenty of revelations recently showing that this is exactly what has happened in the US.
There can be many problems because of this. It is, first of all, apparent that data collected by US is misused. The European Union and United Nations are probably not very dangerous terrorist organizations, but still they rank high on the target list. Data collected by authorities is also supposed to be guarded well and used for our own good only. But keep in mind that a single person, Edward Snowden, could walk out with gigabytes of top secret data. He did the right thing and spoke out when his own ethics couldn’t take it anymore, and that’s why we know about him. But how many secret Snowdens have there been before him? More selfish persons who have exchanged data for a luxury life in some other country without going public. Maybe your data? Are you sure China, Russia or Iran don’t have some of the data that the US authorities have collected about you?
And let’s finally play a little game to remind us about how volatile the world is. Imagine that today’s Internet and computer technology was available in 1920. The Weimar republic, also known as Germany, was blooming in the golden twenties. But Europe was not too steady. The authorities had Word War I in fresh memory and wanted to protect the citizens against external threats. They set up a petabyte-datacenter and stored all mails, Facebook updates, cloud files etc. This was widely accepted as some criminal cases had been solved using the data, and the police was proud to present the cases in media. The twenties passed and the thirties brought depression and new rulers. The datacenter proved to be very useful once again, as it was possible to track everybody who had been in contact with Jews and communists. It also brought a benefit in the war to come because many significant services were located in Germany and foreign companies and state persons had been careless enough to use them. The world map might look different today if this imaginary scenario really had happened.
No, something like that could never happen today, you might be thinking. Well, I can’t predict the future but I bet a lot of people were saying the same in the twenties. So never take the current situation for granted. The world will change, often to the better but sometimes to the worse.
So lack of authority privacy is not something that will hurt you right away in your daily life. Your spouse or friends will not learn embarrassing details about you this way, and it will not drown you in spam. But the long term effect of the stored data is hard to predict and there are plenty of plausible harmful scenarios. This really means that proper privacy legislation and trustworthy authorities is of paramount importance for the Internet. A primary set of personal data is of course needed by the authorities to run society’s daily business. But data exceeding that should only be collected based on a justified suspicion, and not be kept any longer than needed. There need to be transparency and control of this handling to ensure it follows regulations, and to keep up peoples’ trust in the authorities.
So what can I do while waiting for the world to get its act together on authority privacy? Not much, I’m afraid. You could stop using a computer but that’s not convenient. Starting to use encryption extensively is another path, but that’s almost as inconvenient. Technology is not the optimal solution because this isn’t a technical problem. It’s a political problem. Political problems are supposed to be solved in the voting booth. It also helps to support organizations like EFF.
The recent statements from FBI director James Comey is yet another example of the authorities’ opportunistic approach to surveillance. He dislikes the fact that mobile operating systems from Google and Apple now come with strong encryption for data stored on the device. This security feature is naturally essential when you lose your device or if you are a potential espionage target. But the authorities do not like it as it makes investigations harder. What he said was basically that there should be a method for authorities to access data in mobile devices with a proper warrant. This would be needed to effectively fight crime. Going on to list some hated crime types, murder, child abuse, terrorism and so on. And yes, this might at first sound OK. Until you start thinking about it. Let’s translate Comey’s statement into ordinary non-obfuscated English. This is what he really said: “I, James Comey, director of FBI, want every person world-wide to carry a tracking device at all times. This device shall collect the owner’s electronic communications and be able to open cloud services where data is stored. The content of these tracking devices shall on request be made available to the US authorities. We don’t care if this weakens your security, and you shouldn’t care because our goals are more important than your privacy.” Yes, that’s what we are talking about here. The “tracking devices” are of course our mobile phones and other digital gadgets. Our digital lives are already accurate mirrors of our actual lives. Our gadgets do not only contain actual data, they are also a gate to the cloud services because they store passwords. Granting FBI access to mobile devices does not only reveal data on the device. It also opens up all the user’s cloud services, regardless of if they are within US jurisdiction or not. In short. Comey want to put a black box in the pocket of every citizen world-wide. Black boxes that record flight data and communications are justified in cockpits, not in ordinary peoples’ private lives. But wait. What if they really could solve crimes this way? Yes, there would probably be a handful of cases where data gathered this way is crucial. At least enough to make fancy PR and publically show how important it is for the authorities to have access to private data. But even proposing weakening the security of commonly and globally used operating systems is a sign of gross negligence against peoples’ right to security and privacy. The risk is magnitudes bigger than the upside. Comey was diffuse when talking about examples of cases solved using device data. But the history is full of cases solved *without* data from smart devices. Well, just a decade ago we didn’t even have this kind of tracking devices. And the police did succeed in catching murderers and other criminals despite that. You can also today select to not use a smartphone, and thus drop the FBI-tracker. That is your right and you do not break any laws by doing so. Many security-aware criminals are probably operating this way, and many more would if Comey gets what he wants. So it’s very obvious that the FBI must have capability to investigate crime even without turning every phone into a black box. Comey’s proposal is just purely opportunistic, he wants this data because it exists. Not because he really needs it. Safe surfing, Micke
The issue of mass government surveillance may have taken a back seat to other headlines lately, but the new Edward Snowden documentary is bringing it to light once more. CITIZENFOUR, the Laura Poitras film documenting the moments Edward Snowden handed over classified documents detailing the mass indiscriminate and illegal invasions of privacy by the US's National Security Agency, is getting rave reviews ahead of its world premiere. The film is already prescreening in the UK, and along with that, F-Secure's UK office is publishing a research report that highlights the growing concern of the public - specifically, the British public - with mass surveillance. The ‘Nothing to Hide, Nothing to Fear?’ report centers on the concern about surveillance being undertaken by the British government on its own people, as well as foreign nationals. The concerns are justified, as Snowden himself in recent comments warned that the British Government is even worse than its American counterparts, since the founding fathers of the US enshrined in law certain rights which the Brits – with no written constitution – cannot claim. Research* commissioned for the report shows that 86% of Brits do not agree with mass surveillance. Snowden’s leaks last year highlighted the extent to which Western intelligence agencies are snooping on the general populace, including their emails, phone calls, web searches, social media interactions and geo-location. And when you consider the fact that the UK has 5.9 million closed-circuit TV cameras (one for every 11 people, as opposed to one informant per 65 people in the Stasi-controlled East German state), the extent to which Britain has fallen into being a surveillance state becomes shockingly clear. The UK government, of course, insists that indiscriminate surveillance will protect national security. However, the UK's Regulation of Investigatory Powers Act (RIPA) contravenes Article 12 of the Human Rights Act: “No one shall be subjected to arbitrary interference with his privacy, family, home or correspondence.” “We are in unchartered territory and we appear to have sleepwalked here,” said Allen Scott, managing director of F-Secure UK & Ireland. “Little by little, our rights to privacy have been eroded and many people don’t even realise the extent to which they are being monitored. This isn’t targeted surveillance of suspected criminals and terrorists – this is monitoring the lives of the population as a whole.” With the future use of this data uncertain, the British people are showing their concerns. The research showed that 78% of respondents are concerned with the consequences of having their data tracked. This concern will only increase as more privacy-infringing schemes pervade UK government departments, offering up more personal data for GCHQ, the British intelligence agency, to use. Be sure to check out CITIZENFOUR once it hits your part of the world. And if you're in the UK, you can be among the first to see it – see pre-screening venues here: https://citizenfourfilm.com/ READ THE REPORT: Nothing to Hide, Nothing to Fear?

Yet another massive user ID and password leak. This time it affects about 7 million DropBox users, even if DropBox denies they were hacked. As usual, such a hack means that the data these users have stored in DropBox is in jeopardy. It also means that those who use the same ID and password on many services have much bigger troubles. Let’s see what we can learn from this: Always use unique passwords on the services you use. This does not prevent password leaks, but it limits the damage when a leak occur. (A password manager you trust makes this much easier.) Be alert and change your password as soon as you hear about a leak like this. Right now, we don’t know which users are affected. But if you have an old and weak password, it’s a good idea to change it NOW anyway. Changing it one time too many is better than having your confidential data all over the Internet. Pay attention to the security-awareness of the cloud providers you use. This may not have been DropBox’s fault, but it could have been. This is a good opportunity to mention our own younited, which is built with security in mind from the ground up, and is located in a country where the authorities doesn’t do mass surveillance. BTW, Edward also thinks you should consider alternatives to DropBox. DropBox claims this leak happened in some other service that connect to DropBox. This is a plausible explanation and reminds us about the danger of connecting services to each other. If you enter the password of any service into another service, you must ask yourself two questions. Will this company refrain from misusing my data and does this company protect my password sufficiently? By replicating the password to several places you increase the risk that it leaks out. Don’t do that unless you get a significant benefit and trust all places where the password is stored. Two-factor authentication is a great feature that increase security. Use it whenever possible. It should by now be clear that this kind of massive password leaks aren’t rare incidents. We see a constant stream of these and there are probably many leaks that remain unnoticed, or are noticed but stay out of the headlines. We all have to realize that a leak like this will hit us sooner or later. Sorry for sounding like a broken record, if you still have the same password on several services, you should be busy changing them by now.
