The three kinds of privacy threats

WP_000796We 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.

Peer 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.

Provider privacy

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.

Authority privacy

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.

Charlie

I really miss Benjamin Franklin!

January 7th was a sad day. The Charlie Hebdo shooting in Paris was both an attack on free speech and fuel for more aggression against Muslims. And controversially also fuel for even more attacks against free speech. The western society’s relation to free speech is very complicated nowadays. Officially it is still valued as a fundamental right. But it is also seen as a threat, even if politicians are very keen to masquerade free speech reductions as necessary security improvements. British PM Cameron’s recent debacle is an excellent example. In his opinion, there must not be any form of communication that the authorities can’t listen in to, which would mean restrictions on encryption. Non-digital metaphors are usually a good way to explain things like this. This is as smart as banning helmets because they make it harder to recognize criminals riding motorcycles. French president Francois Hollande wanted to join the party and proposed a law making internet providers responsible for users' content in their services. The idea was to make companies like Facebook and Twitter monitor all communication and call Paris as soon as someone talks terrorism. This goes even further than Cameron as it actually would force companies to do the police’s work. But should the phone company also be held responsible if it turns out that a terrorist has been allowed to place calls? And maybe even send mail delivered by the postal service? Hollande did of course not include those as they would help people understand how crazy the idea is. Anything can be misused for criminal purposes. But trying to make providers of things responsible is just madness and hurts the whole society and economy. The important point here is naturally that freedom of speech is a much broader concept than what Charlie Hebdo utilizes. The caricatures express our freedom to communicate publicly without censorship. But there is also another dimension of free speech. Everybody has the right to choose whom they communicate with and whom a message is intended for. This is not just about secrecy and privacy, it is really about being free to exchange opinions without worrying about them being used against you later by some third party. This dimension of free speech would of course not exist in Cameron’s ideal society. So no Cameron and Hollande, you are definitively not Charlie! It’s sad that the great “Je Suis Charlie” -movement has become a symbol for both freedom of speech and hypocrisy. Didn’t you really see anything wrong in first marching in support of Charlie Hebdo in Paris, and then immediately attack freedom of speech yourself? It takes courage to be a leader and balance between security and freedom. Today we really need leaders like Benjamin Franklin, who had guts and said things like “Freedom of speech is a principal pillar of a free government; when this support is taken away, the constitution of a free society is dissolved, and tyranny is erected on its ruins.” and “Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety.”   Safe surfing, Micke   Image by Markus Winkler @ Flickr under CC BY-SA 2.0 via Wikimedia Commons Benjamin Franklin quotes from wikiquote.org

F-Secure shares tips to protect your data on Data Privacy Day

It’s Data Privacy Day, and Companies Know More About You Than Ever

Nowadays companies know more about you than ever. But do you know what they’re doing with all your data? Today's Data Privacy Day, and at F-Secure we usually talk a lot about defending your personal data from online criminals: the likes of hackers, scammers and WiFi snoops. But today we'd like to talk a little about how your privacy can be invaded completely legally - by private businesses who collect your data, and how you can protect yourself. We give companies unprecedented access to our personal info and shopping habits. We give knowingly, such as when we fill out a website form. We also give in ways we may not be aware of, in the case of online advertisers who track our clicks around the web and gain insight into our interests and preferences. These advertisers are building up detailed, extensive profiles about us so they can target us with online ads we'll be more likely to click on. The apps we install garner even more of our information. Not to mention what we give to social networks and our email providers. The result: a mass of digital data is spread around about each of us that's super difficult to control. An Adroit Digital study found that 58% of respondents aren't comfortable with the amount of information they have to give to get special offers or services from retailers, and 82% are uncomfortable with the amount of information online advertisers have about them. And according to a survey by SAS, more than 69% of respondents agree that recent news events have increased their concerns about their data in the hands of businesses. News events like all-too-common data breaches, no doubt. But there's also a skepticism of what businesses and organizations may do with the data they are entrusted with. Last week, for example, Americans were shocked to learn that their government’s healthcare website had been quietly funneling consumers’ personal details along to advertising and analytics companies. At F-Secure, we've always been extremely conscious about the responsibility we have to respect the privacy of our customers' data and content. We recently put our core privacy principles into a structured form and shared them with the world - and Micke delved into them in a recent 3-part series. We also are passionate about helping you protect your own privacy - which is why we've created privacy-centered products like Freedome, which keeps online advertisers out of your business by blocking tracking. At the very least, we hope to inspire you to be, if not already, a little more aware of your data trail. So in celebration of Data Privacy Day, here are a few tips for helping you keep from spreading your data too far: 6 Tips for Defending Your Personal Data Check before committing. If your relationship with a business means you’ll be giving up a lot of data to them, check for a privacy policy or principles that outline how they use customer data Choose privacy. Turn on Private or Incognito mode in your web browser so that websites can’t use cookies to identify you Check your settings. Use this handy list to check your privacy settings on all the most popular sites, from ecommerce to social media and more. Provided by the folks behind Data Privacy Day. Search carefree. Use F-Secure Search, our free search engine that makes sure your search history is not stored anywhere or linked to you Get informed. Use F-Secure App Permissions, our free app that lets you know what information you’re giving up to the apps you’ve installed on your phone Keep advertisers at arms' length. Use F-Secure Freedome, our privacy app that blocks third-party online advertisers from following you around the Web. Freedome is available for a free 14-day trial here.   Happy Data Privacy Day!   Image courtesy Philippe Teuwen, flickr.com

You’re Being Tracked Wherever You Go – Here’s How to Fight Back From Your PC!

You're searching online for a baby gift for a friend's newborn, and then for a while you're followed by diaper ads on practically every site you visit. Ever notice something like that happening to you? Yes, the web can be an eerie place. Intelligence agencies and criminals aren’t the only people who may be tracking your online behavior - there’s a lot more to your browsing session than meets the eye. Take, for example, this F-Secure Labs study that found that of the 100 most popular URLs in the world, only 15 percent are actually accessed by real people. The other 85 percent are third-party sites that are accessed behind the scenes of your browsing session, by the sites you visit. And over half of these third-party sites are tracking-related. They are helping build up an online profile of you and your browsing habits. Why? So marketers can better target you with ads that meet your interests and preferences - or at least try to, in the case of the diaper ads. How does it work? When you visit a site with ads, you'll be tracked by the marketing company behind the ads on that site. And one marketing company may be working with a huge network of other websites. So whenever you visit another site that also has a relationship with that marketer, the marketer captures more and more data about you and your online behavior. All this data goes into an extensive profile that is being built up about you. If that sounds a little creepy, rest assured that you can regain control of your digital privacy. There’s an easy way to block advertisers from tracking you everywhere you go. Last year we launched F-Secure Freedome to stop tracking on your mobile device (to date, Freedome has already blocked over 900 million tracking attempts globally). And now there's good news - today we're unveiling Freedome for your Windows PC! Freedome for Windows has the same privacy features as the mobile versions, protecting you from trackers and hackers. It's got the same VPN technology to protect your browsing session from snoops while using public Wi-Fi. In addition, it also includes a new Private Search feature that offers tools so you can get your search engine results without the tracking. Since the Snowden revelations, we as consumers have become more and more aware that we may be revealing the most intimate details of our lives through our connected devices. According to a recent study by the Pew Research Center Internet Project, 91% of adults in the survey agree that consumers have lost control over how personal information is collected and used by companies. If you're concerned too, download a free 14-day trial of Freedome for your Windows PC. And let us know what you think!   Banner image courtesy of Filip Goc, flickr.com
