How to Keep Your Private Conversations Private for Real
Don't get doxed.
This essay also appeared in The Age.
A decade ago, I wrote about the death of ephemeral conversation. As computers were becoming ubiquitous, some unintended changes happened, too: Before computers, what we said disappeared once we’d said it. Neither face-to-face conversations nor telephone conversations were routinely recorded. A permanent communication was something different and special; we called it correspondence.
The Internet changed this. We now chat by text message and email, on Facebook and on Instagram. These conversations—with friends, lovers, colleagues, fellow employees—all leave electronic trails. And while we know this intellectually, we haven’t truly internalized it. We still think of conversation as ephemeral, forgetting that we’re being recorded and what we say has the permanence of correspondence…

As a foreigner, I know very little about Australian politics. I don’t know anything about Senator Vanstone, her politics, her policies, or her party. I have no idea what she stands for. But as a security technologist, I agree 100% with her comments. Most airplane security is what I call “security theater”: ineffective measures designed to make people feel better about flying…
