Topic: Face recognition linked to Bitcoin (Read 1481 times)

Not a good idea, there is a risk to leak your privacy.
                                                                                                             

face expressions are risky, you can accidentally repeat it in pubblic why you are smiling or something else, i'm not in favor for it for any kind of security

it would be better to use your eyes but when you go public you wear a contact lenses that will change the color, so even if someone take photo he can't do shit

with so many possible scenarios of security options, with a security company you get a phone call that ask you for a pin after you already introduce your home password or pin in the local pad, pin on the phone and an agent comes on and ask you 2 questions with a voice recognition software, Is everything ok mr Anderson? can i please have the last for digits of your social security number.

lol add to that a faceregonition so you could get this answer you may send bitcoin now sir! 

Why bother making effort taking images? With today's society (widespread of online content sharing and cloud computing), it's most likely going to be on social networks such as Instagram, Facebook, Twitter, MySpace. Need I go on?

Anything that's public shouldn't be used to encapsulate private data. This specifically applies to Bitcoin private keys.

What about face recognition gives you the address and fingerprint+pin the private key?
Im sure there are not that many hand photos out there

This idea gets even worse the more you think about it:

OK, so lets assume it isn't really easy to systematically capture biometrics with digitial imaging equipment from miles away. Instead, imagine the $5 wrench attack against 2FA facial recognition + iris scans. Change the name to "5 seconds" attack, $5 wrench not even required. Probably don't even need to make physical contact, just close enough to grab some quick images. Tautologically dumb idea is a tautologically dumb idea.

My passport has face recognition. My border don't recognise my face no more and it's only five years old (the passport, not the face).

In theory iris/DNA/fingerprint recognition sounds secure but hacking is going to always be running alongside progress or taking a step up.

This thread is making me sick
 

No face recognition linked to BTC use. That's it. Full stop!

this can't still overcome the movements of the eyes that i was suggesting in the first page, that's the real password, and only you will know it, it would also be very difficult if not impossible to mimic

To conclude with @Carlton Banks quotes; both iris, and fingerprints could be extracted with an ordinary photograph, and facial recognition wouldn't be suitable because of its indeterministic nature; this makes it improbable and almost impossible to obtain the same values, unless a central server was introduced, thus, making your private keys as safe as an online wallet.

Furthermore, introducing "tollerance," would decrease the effectiveness of a relationship (between private key and facially recognised key), this would increase the possibility of obtaining identical values with difference faces, therefore, increasing the likelihood of mismatches, and sophisticated attacks from different sources such as photographs...

/thread (finally)

Hehe i don't think many people would want a unique BTC address linked to their face.

Good luck changing the patterns on your iris.

You can only link face recognition to bitcoin (or any other digital key) if using a central server.

The problem is that biometric is not strictly deterministic, which is required for a digital key.
There is a ton of research in this area, e.g. if you can add a tollerance to where you hit on the epliptic curve.

But for now, would you need a central server to map your biometric against a database and find the match with higest proberbility, then will the server return the digital key.

Unfortunally with current technoligy can you not link a biometric with a digital key.
If you could, then would it open a whole new possiblility of applications.
The most interesting application is to improve the demochracy, you could improve the voting system significantly by using your biosignature as a digital key and then sign your vote online.

In regards to the authentication information being on display, you should probably read this as well - A technic which allows the extraction of ones fingerprint with only a cutout piece of a photograph... Face recognition wouldn't be anymore difficult to fool, if one had a clear photograph which could be used to extract facial structures...

The difference being that the authentication information isn't even stored on the cards at all, and still they are fairly easy to defraud. If you use a face scan, the literal authentication information is permanently on display, your fingerprint information is all over every single door you open and every surface you use. Fingerprint spoofing tech has existed for decades, and is now cheap and reliable. This idea is only going to get worse with time, and it's already a bad idea now.

Good question.

Big data has enough information already to let hackers steal our identity. Why provide the more information that we cannot ever change?

You change as you age, but nothing stops you from re-scanning your features and doing some sort of 2FA to confirm this change. This sort of application would not be used

to store your life savings, because all security have some flaws. It's only for the day-to-day trading, like we move around with a physical wallet now.

You still have the majority of your life savings in cold storage, not connected or linked to this identity.

Let's be honest.. most people walk around with a wallet, with 1 or 2 or 3 credit cards and also their ATM card linked to their life savings, as you put it. The probability

for someone to get hold of that and to get your password is much higher or the same as someone going through the trouble to fake your face/finger print/retina etc...

It's not 100% secure {nothing is} but it opens up a opportunity for you not to walk around with a wallet full of cash and loaded with credit cards.

Imagine this scenario... you get knocked out, and you lose your memory. Someone takes you to the hospital... You get there and they admit you, without you or them

knowing who you are. You would still be able to pay for the treatment, without you knowing who you are. {For those people saying.. people would knock you out, and then scan

you for your money... Well, what stops them from doing that now? ....Would a merchant do business with a customer that is unconscious? }

One thing to take note is that human complexion changes especially with increasing age, so I don’t see how feasible would that be to link address to face recognition. More over, there’s chances that could even lead to security getting compromised if let’s say somebody could duplicate and create the exact facial expression almost similar as what you see in wax museum. I would accept that being done for other non-important applications but definitely not for addresses holding your life savings.
