Then again, did people really have privacy when living in small villages in the countryside where everybody knew each other?
I think the rise of privacy came with the development of big urban areas...
There are some secrets that everyone, even in a family, keeps. People can't know if you don't tell them, but with the advent of the computerized era, information escapes even if you don't tell it.
The one I am concerned is not my friend sharing a photo, is the data corporations and governments capture about me (with or without me knowing about). It was said here also, if you can make an infringement of the law, never know about it, and be held guilty by data you didn't even know to exist (the example being the import of foreign cheese in the US, even for personal use).
