Hypothetical:

Today is your son's 8th birthday party.  You used your smartphone to take an amazing picture of him blowing out the candles on his cake.

You then share that picture with family and friends.  Maybe via email.  Maybe via some social media.

Based on that picture -- and that picture alone -- what information are you, perhaps unknowingly, sharing with others?

Inside each picture you take is a small mountain of data -- known as EXIF data -- that is made openly available to everyone.  And some of it is pretty gosh-darned personal.

Let's go over what that data is, what a potential eavesdropper can learn, and how to minimize the risk when sharing pictures with others.
