Regain Privacy: How to Protect Your Data on the Internet

Preserving privacy on the Internet isn’t easy: advertisers are finding ever more sophisticated ways to collect user data, and new, convenient technology detracts from the negative impact on privacy. The resulting decline in online privacy is further fueled by the fact that online privacy can, due to its abstract nature, be quite hard to grasp.
