Privacy is like nobody sees what you are doing, but potentially knowing who you are. For example, you are privately at your own home. Nobody has an idea of what do you do at a time, but everybody knows that you are being located in this house. And take another example, as when you email your friend it is private to you and your friend but not publicly to everyone. And another example, when you have created a file with a password, only you have the key to unlock it then the data is private over there.


Anonymity is like doing all your activities by hiding your true identity and others can see your actions, but may not have an idea who you are.

For example, Browsing using the Tor browser and posting a message anonymously in any of the discussion forums.
