The advantage of Big Data compared to traditional scientific methods is obvious, however, there are justified concerns that their application will lead to total surveillance and violation of civil liberties. Confidentiality and security of personal information is not guaranteed, not only online, but also in everyday life.
The paradox is that the fundamental principle of Big Data contains a threat: if there is a large amount of data, anonymisation is not possible altogether despite all attempts to make it otherwise.
Scientists are trying to offer solutions to the problem of cyber security, but the reality is that , to exist in the modern world, you have to come to terms with total surveillance. Your mobile phone, a "smart" billboard near your house, a flock of drones with cameras or an ordinary coffee machine – they all are helping "Big Brother" to eavesdrop on your personal life.
