- Jolter 5y agoIf you have to go to a store, wouldn’t a government issued ID be sufficient and less invasive?
- ummonk 5y agoWhat if you lose your government ID? What if someone fakes your ID?
- Jolter 5y agoWhat if someone bribes the person taking the dna sample? Corrupt telecom employees have already been complicit in ID fraud by redirecting SMS traffic to attackers. How does the business know the DNA used to set up an account for Bob comes from him and not from attacker Bill? They would have to take his ID at his first visit so you’re still vulnerable to ID fraud. We can argue back and forth but IMO the DNA idea has two problems: 1 It is too invasive as it requires customers to reveal their DNA to the business. 2 It is impractical. Firstly, the technology doesn’t exist. Secondly, it requires a physical visit to authenticate.

- ipaddr 5y agoWhy not take cheek samples? Wouldn't a finger print be easier? Why would you need to go to the store plenty of dna sequencing happens over the mail for ancestry and alike. Partner with them and offer discounted dna results. Ideally you do this once and keep a card and use it everywhere.
- ummonk 5y agoYeah thinking about it more it's probably a cheek swab and not a blood prick. And yeah the card would be the more regularly used 2FA. The DNA test is just for when you lose your card. As to doing it by mail, that may be potentially doable, but one would need to think through how to prevent e.g. stolen saliva, MITM mail sample interceptions, etc.

- crazygringo 5y agoI'm pretty sure I've seen sci-fi movies where they get around this with a fake layer of skin applied and engineered/stolen blood with the desired DNA. Biometrics are never perfect. Sometimes they can be forged (even something as simple as a printout of a human face looking in a camera), other times you take advantage of a tech vulnerability to feed the desired biometric data in directly without needing to produce anything physical at all.
- astura 5y agoThis sort of thing actually happened https://en.wikipedia.org/wiki/John_Schneeberger https://en.wikipedia.org/wiki/John_Schneeberger >John Schneeberger (born 1961) is a North Rhodesian-born former physician who drugged and raped one of his female patients and also his stepdaughter while a physician in Canada. For years, he evaded arrest by implanting a fake blood sample inside a plastic tube in his arm, which confounded DNA test results. >During his 1999 trial, Schneeberger revealed the method he used to foil the DNA tests. He implanted a 15 cm Penrose drain filled with another man's blood and anticoagulants in his arm.[5] During tests, he tricked the laboratory technician into taking the blood sample from the place the tube was planted.
- ummonk 5y agoDamn. Off topic but once again I'm reminded of how ridiculously lenient most western countries (aside from the US) are towards violent criminals.
- qvq 5y agoIdentical twins would be a problem. There's no foolproof way of verifying identity today. It might be possible for a system to observe you and generate a set of identifiers. I doubt we can make anything accurate enough to be usable today. Maybe in a decade or two.
- zxcvbn4038 5y agoChimeras are another problem, although very rare.
- todd8 5y agoTheir birthmarks and finger prints are different (out of curiosity I verified this myself with twins that were students of mine) and I believe that their iris scans are different. So a combination of DNA and fingerprints/iris scans should be foolproof.
