Hacker News Reader

When I started this I spent some time googling to see what sort of harm came come from your fingerprints being leaked and I couldn’t find anything concrete. It’s not trivial to take a photo of a fingerprint and turn it into something capable of fooling a smartphone fingerprint reader. Someone with the ability to do that probably also have the ability to lift your print from the thousands of things you touch in your daily life.

As opposed to the database the state agencies already have because they take your fingerprints when you get ID?

They mean pub key / certificate fingerprints. Gosh... :)

I’ll happily engrave your public key on a ring!

Huh? Is building a database of actual finger fingerprints not worthwhile?

Not really, unless you're trying to build up a private fingerprint collection which can't be used for criminal cases anyway.

> build a database for any state agencies

As opposed to building a database for private agencies?
