- irjustin 7y agoAs another person said, you're literally leaving it everywhere you go. If you need a blood sample, then would donating blood be considered compromising security? Identity is what your DNA is. Password is a secret. Your DNA is not a secret.
- GrinningFool 7y agoI think requiring you to be physically present and having a human take the sample in a prescribed manner serves as an effective 'password' - unless it's a live sample, the DNA is useless.
- rckoepke 7y agoThe movie Gattaca showed in detail how routine spoofing of a variety of IRL DNA samples could work.
- irjustin 7y agoI think there's a misunderstanding of what is possible with DNA[0]. We take DNA from dead stuff all the time. I will agree with "you have to be physically present" is good enough password. This is Yubikey, which works fantastic. The problem with DNA is when it is compromised - you can't throw it away/change it without exorbant effort (bone marrow transplant? and then you're simply taking on someone else's identity? is that identity theft?).

- ummonk 7y agoI think people are misunderstanding what is being suggested here. The idea is that, for example, to unlock your bank account, you have to go to the bank where trusted bank employees will extract your DNA and have it sequenced, resulting in you being given access again. Others cannot spoof being you in this scenario because they cannot implant your DNA in themselves.
- irjustin 7y agoAh you're right. I've re-read it and it is physically present someone verifying you using your DNA. Which I agree, that works great, but quite narrow in the the use cases at that point.
- aabbcc1241 7y agoConsider if you're kidnapped and extracted DNA in unwilling manner
- mattnewton 7y agoThat's exactly what they did in the movie Gattica- it's hard but seems totally possible. I'd rather have multiple revokable keys.
- dredmorbius 7y agoYour DNA can show up all over the place.
