SHORT: End-to-end encryption’s fatal flaw

End-to-end encryption is supposed to be ultra-safe.

Unfortunately, it’s not.

Even though it sounds good on paper, the way E2EE is coded and used can make all the difference between security and epic data leaks.

More on Metadata

In short, metadata is not actual information about a person/thing, but related information relevant to the target.

For example, if each user is represented by a unique, random code, you might think that’s secure. But what happens if I track all those different secret codes, and then make a map of who’s talking to each other?

And then, what if for that Who’s Chatting map, I get ONE piece of extra data that I know is linked to a particular person? It could be data, metadata, a login cookie – something…

In that case, I might be able label an entire group of people as Republicans, males, terrorists, Buddhists, or whatever.

Rinse and repeat, and you can easily see how metadata can be used to track just about everyone. It’s not the individual piece of metadata that’s important, but the fact that I have a HUGE group of users, each of whom has metadata. And every bit of metadata can be related to other bits in some way.

So yeah, it’s a pickle!
