Technologies that do not require physical installation onto a network. These technologies can be easily transported to different locations for deployment.
Technologies that require physical installation onto a network to perform communications surveillance.
We're going to focus on two main categories of surveillance:
- Network surveillance
- Tactical surveillance
Following that, we will look at the communications surveillance technologies available to some actors, which facilitate their interference with our privacy
It only takes four location points to uniquely identify you in a dataset of 1,500,000 people
In the first part of this chapter, we’re going to explore the actors who threaten the right to privacy:
- The private sector
Key concepts: Threats to the right to privacy
All of a sudden the content of the call or what you write in an email doesn’t seem to matter much in getting revealing information, does it?
When it comes to internet communications, the situation is just as concerning
A tool released in 2013 by MIT, called "Immersion" helps to illustrate how analysing “just” metadata of an email can reveal whole networks and groups of contacts.
How is data communicated?
Take a mobile network:
Your phone gives away its location constantly by sending out signals to different base stations as you move around the city.
The amount of metadata generated in the course of a communication is staggering
IMSI - International Mobile Subscriber Identity is a unique identifier stored on your SIM card to associate with the relevant provider of your service
Then when your phone connects to a base station it reveals metadata to identify itself to the network and to associate it with the correct provider
All it is doing is trying to give you the best service possible
All of this information may be necessary…and totally revealing
Didn't know these existed?
Open up the keypad on your phone like you’re going to dial a number and dial the code *#06# into your phone.You’ll get your own unique IMEI identifier displayed to you. Both the IMSI and the IMEI are completely unique to your phone and are transmitted almost instantaneously.
IMEI - International Mobile Equipment Identifier is a unique identifier that identifies your handset to the network
