When you take selfies with your smart phone, it may contain something called a geotag. A geotag reveals your exact location on a map. Removing this tag from a picture before posting it to social media is a practice that belongs to which principle?
Answer: Information Hiding
Geotags are commonly used by people using public information to social engineer their prey. Imagine when trying to hack an account, a hacker sees your security question is your grandparents address. A social engineer may begin looking through your social media for pictures including your grandparents. They will get location information from those photos and try to solve the security question. Although Instagram has removed their geotags, Facebook, Snapchat, Google and many other websites and services still hold on to image location data.
