Authorized Pets Only

found on Reddit

Having seen how difficult face recognition can be in humans, I don't have a lot of faith in this application either. Among all the other problems, have fun enrolling your pets when they're soaking wet, because that's what they're going to look like when they want in in a hurry.

Cutting edge security

Something no one really wants to talk about is the fact that most biometric authentication is just one knife accident away from being token-based authentication.

Simon says: HODL

from here and here (image source)

 Apparently the CEO of an AI company is also involved in a project that will give free cryptocurrency to people in exchange for scans of their eyeballs. They really want you to believe that it's not a dystopian nightmare, but all I can think of is how Simon Phoenix broke out of prison in Demolition Man. Even if the technology can spot attempts to trick it, some people are still going to try.

Brute Force: Now with less brutality

from here and here

My fingers are resting just a little bit easier knowing that there are now attacks against fingerprint authentication that involve a dictionary of digitized fingerprints. I'd just as soon the vulnerabilities involved not get fixed as that would force attackers back to using less civilized means. 

I suppose it might be more accurate to call it a dictionary attack rather than a brute force attack, but what do I know?

Maybe it's just the work you had done

found on Dump A Day

I can't imagine facial recognition is going to handle facial modification all that well. If you get cosmetic surgery, be prepared to re-enroll.

You can't just pay lip service to data protection

from here and here

Clearview AI, the biometric surveillance company everyone loves to hate because they add you to their system without your consent, is apparently ignoring French regulators trying to call it to heel over violations of the European Union's GDPR. While they haven't paid the fines yet, they're now going to be growing by the day, and the EU has already thrown out existing data transfer arrangements with the US over GDPR violations (like the Cambridge Analytica scandal) in the past.

Can't be shy if you want to fly

from here and here

I hope you all don't mind biometric surveillance creeping slowly but steadily into your everyday lives, because it sounds like the creeps at the TSA have definitely settled on the creeping strategy.

Face Rec can get rekt

found on eBaum's World

I think anyone who sees this image captured by a face recognition system (assuming the system can even capture this as a face) is going to assume the system is on the fritz.

Biometric racism

found on Reddit

How can technology be racist? Well this is a perfect example. The people who made this biometric authentication technology had a racial bias in favour of certain facial features and failed to account for or consider any races that didn't meet their criteria - thus this error message telling someone to open their eyes wider than they naturally would open. It means they can't use the technology as easily (or at all) which means they don't get access to the same level of security that someone from a different race would.

Give a face recognition system nightmares

from here and here (image source)

Right now PPE is doing a fine job of covering up most of my facial features when I go outside, but the pandemic won't last forever (hopefully), so I'm definitely considering this as an alternative. It's either this or go around looking like a bank robber.

Anti Facial Recognition mask

Product Page

I couldn't find any research about this specific pattern to suggest it does more than any other mask to foil face recognition, but face masks in general do significantly lower the confidence of a match, and if you pair this with a pair of dark sunglasses you should be good to go even if it's a dud. On the other hand, the pattern could also serve as a conversation starter so you could help others start thinking critically about whether they want to be surveilled by facial recognition systems.

It's more "secure"

from here and here

There are some scenarios where I can see fingerprint biometrics providing a lot of additional security, but phones and laptops aren't among them. It's like a combination lock with the combination written on it. They do provide convenience, and maybe that's what we should be caring about, but we shouldn't try to pretend it's for security

A face recognition pushmi-pullyu

from here and here (image source)

It may be terrible taste, but it actually looks like pretty good execution. I can definitely see face rec systems falling for it. Now the question is, does that resemble his actual face or is he going to try and pull a fast one.

Good thing you didn't forget which finger to use

found on Acid Cow

There are a variety of reasons why unlocking a phone with just a fingerprint might not be a good idea (such as the fact that it can be entered without your consent by an intimate contact or compelled from you by the authorities) but if those kinds of adversaries aren't part of your threat model then forgetfulness is certainly an argument in favour of fingerprint unlock.

Have fun with passwordless authentication

found on Reddit

They've been trying to get rid of passwords for years, opting instead for things like your phone (as a token) or biometrics, or both. Unfortunately alternatives to passwords require additional hardware and just aren't as reliable as passwords.

Turn the other cheek

from here and here (image source)

I sometimes question whether fingerprints are actually more secure than passwords, but I'm not sure if buttprints have the same caveats

That's one way to fight biometric surveillance

from here and here (image source)

So would you be willing to turn yourself into a human potato head* if it meant you could foil automated surveillance systems? 

(*What else would you call it with all those eyes?)

Your buttprint is your password

found on Reddit

People keep telling us how secure biometrics are, but what's even more secure than biometrics? Weird biometrics! My password is a body part but you don't know which part.

Computerphile: Fingerprint Recognition


Watch on YouTube

There are of course additional steps one can add to the process to make sure you're dealing with a live genuine finger rather than some sort of facsimile, but it still boils down to comparing minutae points.

For Receptacle Use Only

from here and here

I never imagined smart light bulbs could measure biometric properties like body temperature and heart rate. I suppose they must be emitting more than just visible light... at least I hope that's how it works. 

The problem now is how can you tell if someone else is using such a bulb and measuring your biometrics without your knowledge or consent?
