The people we trust the most with our most vulnerable secrets or ideas are capable of betraying our trust. Nothing is impossible. Every thing we share in life has the potential to be exposed and damaged. Almost the only way of not being hurt in life is never sharing ourselves with others or taking a risk.
When you get home and pay your bill over your internet banking, you have no idea where this information is going through. When you send a picture to your friend that lives across the street, that information can go to Germany and back before reaching your friend. Everything seems and feels so simple and intuitive, but it all happens in the dark and we have no control. Privacy doesn't exist in the internet for any of us in our daily routine and it is naive to think otherwise. A password doesn't protect my privacy, it gives me the illusion of privacy.
