People love sharing pictures of their cats. While this can be fun, it can also be a serious privacy risk if you’re not careful.

That’s because almost every mobile phone’s camera includes metadata about a picture such as the location of the mobile phone when the picture was taken.¬†Owen Mundy, an art professor at Florida State university, has created a website called “I know where your cat lives” to raise awareness of how people unwittingly give up their privacy online.

“Geographic data is sensitive,” Owen Mundy said. “A picture can only say so much. But if someone wants to do you harm or stalk you, or you live in a place where free speech is limited, anyone can track where you are.¬†Privacy is an ongoing, changing thing, and I hope this becomes part of the conversation.”
