An increasing amount of data is becoming available on the internet. Each and every one of the user is constantly producing and releasing data about themselves. The authors do this either by moving around passively - the people behavior being registered by cameras or card usage - or by logging onto their PCs and surfing the net. The volumes of data make up what has been designated 'Big data' - where data about individuals, groups and periods of time are combined into bigger groups or longer periods of time. The amount of data in their world has been exploding.
