Our Facebook updates, Google searches, Twitter messages as well as whom we send text messages to or call, all become part of the gigantic digital haystack which is analysed to identify any suspicious patterns.

How are we affected by the fact that someone may be looking over our shoulder at any given time? People who know they are being watched, change their behaviour because the context is changed – the trust in the surroundings has changed.
