Aleks was once asked by a friend to track down an invisible man - a character with no digital footprint at all. How does someone not exist in this media-saturated moment, and why does that make it seem like he has something to hide?

Find the right balance between personal privacy and personal transparency, Aleks speaks with information security professionals who hunt for bad guys by puzzling together the pieces of leaked databases and hacked accounts, digital analysts who peer into our devices to catch us out when we’re acting out of character, and undercover operatives who build believable online legends to slip unnoticed into the daily life of the internet. As we grapple with what it means to be able to edit our personal histories in an age when every moment of our lives is expected to be available at the click of a button, how do we demonstrate that beyond a shadow of a doubt, a fake person is real?

In this episode, Aleks stumbles over the line between fiction and reality to see what the people scrubbing themselves clean and the people fabricating entirely new personas can tell us about what we expect a human being to be.
