Mass surveillance systems

Even if you're not doing anything wrong, you're being watched and recorded. Edward Snowden

Mass surveillance systems are nothing new. If in the past that mainly came down to intercepting phone calls and telegrams, in the digital era the collected information is mostly about gathering the data about activity and communication on the Internet and cell phone services. 

In the majority of cases mass surveillance systems are responsible for legally collecting data via various communications channels. This includes collection and storing phone calls, the coordinates that fix the location of the caller’s calls – the so-called billing, and, of course, the collection and storing Internet traffic. Users are aware of data collection, at least, the society doesn’t find anything surprising about the existence of such systems.

Of course, there is the bigger evil – the illegal data collection, for instance, the program called RAMPART-A, one of the disclosures made by Edward Snowden. According to the information published by NSA, USA secretly negotiated agreements with 33 countries in Western and Eastern Europe, Asia and Africa to access and monitor fiber-optic cables carrying internet data in those nations.

Almost every country has its own mass data collection system: in Russia – this is COMP, in Canada, Australia, New Zealand, the US and Great Britain – ECHELON, in France – Frenchelon, in China – Golden Shield. You are going to find out more about these systems in the chapter devoted to mass surveillance systems and the methods of protection against them.

Progress constantly moves along, and these systems periodically evolve. New solutions for storing information emerge, capable of storing more data in smaller space, with a smaller price tag or more efficiently performing the search for the required information in the collected data.

For instance, take the relatively new technology – search by voiceprint. If the government possesses the records of your voice, they can always identify your calls, no matter what the phone number you used when making them. Such solutions are costly and employed by special services of just a few countries.


Special services don’t have enough space for storing my data over many years.


Unfortunately, they have enough space to store information about every person on the planet for many years ahead.

Take a look at the photo below. You may have already seen this building. This is NSA’s Utah Data Center that probably stores all your calls, correspondence in IM services and on social networks, emails over the last years.

Mass surveillance systems

You must’ve heard about the methods of protection against mass surveillance, similar instructions are actively spread on the Internet by human rights groups and activists. According to them, to guard against mass surveillance, it suffices to encrypt your communications, or better yet, use VPN for comprehensive encryption of your entire Internet traffic.

They do have a point here, don’t they? How can you be watched when your traffic is encrypted? VPN can really encrypt your entire Internet traffic up to the VPN server, and the system of data interception at the level of your Internet provider will get only encrypted traffic. But on the VPN server your traffic will be decrypted, and at best, you’ll be left with the encrypted connection up to site (HTTPS), which is no rocket science for special services.

Interview widget: Do you use VPN or Tor when using the Internet?

If the country where your VPN server is located doesn’t have a mass data collection system in place (though I know none such countries), it may be farther on it
