Nowadays, if you surf the web like any normal person, chances are your movements on the internet will be tracked. There are a lot of companies tracking you and building detailed profiles about your behaviour on the internet. With all the news about the revelations of Edward Snowden about the mass surveillance going on by the NSA, GCHQ and other Three-letter agencies, you might almost forget that there is a whole world out there with various corporate entities who also build profiles about you, either with or without your knowledge and consent.
Why big corporations are tracking you and building profiles about you
Major problems with personalized results
As more and more people discover their content and news through personalized feeds like those found on Twitter and Facebook etcetera, the stuff that matters gets pushed off the feed. People who live in the filter bubble, a term coined by Eli Pariser, can easily miss vital information about certain major events. I’ll give an example. During the Egyptian Revolution of 2011, two people may be getting two completely different results on Google. One, who is more interested in holidays, according to the profile built up by Google, may be getting more links in the search engine results page (SERP) about holidays to Egypt, and miss news about the revolution completely, whereas someone who is more politically active, may only get links to news sites with articles about the revolution. This is already a major difference in the results you get. You may be under the impression that the results generated by Google are the same for everyone where, evidently, they are not. They are generated based on your personal interests, information you and/or your computer shared with Google. The question is: is it really always a good thing that we only get to see stuff we are interested in? And that some big mega-corporation like Google is deciding that for us? This way we may miss vital information, as the information that reaches us gets censored transparently, without our knowledge or consent. If we only get our news from personalized news feeds like those provided by Facebook, Google and Twitter, we may miss out on a lot of information. Therefore it is prudent to always use as many different sources of information as possible, so efforts to filter our results and trap us in the filter bubble have as little effect on us as possible.
Steps we can take to arm ourselves
Right, am I done yet?
The tips above are only good advice in general, and will protect against most profiling attempts by advertising and other profit-oriented companies which try and sell your profile to their clients, but won’t protect you against a determined, well-financed adversary like an intelligence agency. For this, you need to encrypt the hell out of your life, and use crypto like AES, etc. (VeraCrypt) and PGP (GnuPG) as much as possible. Why should we be making it easy for the spooks? In that case, you might also read up on VPNs, and check out the Tor network (but keep in mind that many exit nodes are run by intelligence agencies, so always use end-to-end encryption (e.g. HTTPS) when using Tor). In this case, also try to avoid using any service made available by any US company whatsoever. Think SAAS providers, cloud services, etc. Because of the Patriot Act, US government agencies (and of course, through them, other, foreign intelligence agencies which cooperate with the Americans) can easily request any and all information some company with US ties stores about you. So try to avoid that as much as possible in this case. This is the reason why I’ve moved my online persona to Switzerland, and also running my mail on a mail server that I control. Also think about the security of your devices, and only run free software, so there’s less chance of a back-door hidden in the software you use. But you can read up more on the measures you can take when you’re up against a more powerful adversary. But with the above tips, you’ll be well on your way to better securing your communications.
