Human Hash

[bitcoinpeddler]

1) for every human must be a unique hash id
2) it is not possible to build this hash id without the real person ( it is not possible to build in an automatic way these id)
3) decentralized , without a certifier authority

It doesn't seem possible for it to be decentralized.

If you were to go the DNA route you could do sha 256(DNA+password)
That would prevent problems with twins/DNA thieves

Biometrics are not a secure identification method, they change and can be faked relatively easily. Digitizing human identity is a big challenge when it comes to making it foolproof and accessible but still secure. We've had private key encryption for decades but it's difficult to get people to use it, so phone's etc use biometrics because they are easy for people to implement.

I'm not sure if you already have seen this or if it will be of use to you, but here is a whitepaper on a decentralized secure identification system.  I haven't read the whitepaper thoroughly, so my apologies if it doesn't apply to your post.

You need a ZK-SNARK to make this happen.

That means, you need some sequence of bytes that gets generated (because i assume you'd want to store it on a blockchain) which would need some information that a human has that a computer doesn't.

Consider this.
Assume a human does generate some byte sequence that a computer cannot produce. The human also needs to prove that he/she has provided the correct sequence.
This proof will be an algorithm that a computer can run on the byte sequence.

We have been able to device SNARKs in math because we understand the fundamentals of modulo operations (In case of public private key encryption), because we invented both math and computers.

I am not sure if we have an understanding at that level for any property associated with humans.
What is the underlying logic that creates a fingerprint/DNA? Can that logic be exploited to produce ZK-SNARKs?


PS : I add "ZK" because i'd assume you want to maintain privacy of the human

It's done now, it's called a faucet and currently the best tech is captchas.  You could have a captcha use an algorithm to analyze fingerprints, and each unique fingerprint gets 1 coin per day.  captcha's can be done multiple times and theoretically you could use fake fingerprints but still it is pretty good proof you aren't a bot.  However the fingerprint reading algorithm would need to be cryptographic in the sense that it is easy to verify a print but impossible to create a print digitally to fool the algorithm.

The idea is brilliant, you could use facial recognition function and biometric locks for unique I.D.

As of now mate I think every physical recognition can be faked for instance finger prints and facial recognition.

And what might be this biometric locks, its the same as the others they could only develop algorithms to match up every person's identity?

That's technology for you.

In the end, everything that have mentioned by the author is possible except for being decentralized, its quite impossible - at the moment.

There is a problem easily solved by humans and hard for a computer: recognition of another human.
Consider this solution:
One is initially identified by a picture or a short introductory video. Then while using the network one has to undergo an identification procedure which includes three 1 minute interviews with strangers via some kind of a videochat.
Mining = working as one of the strangers that identifies that someone who is trying to make a transaction is a real person and he is the same person as on the identification introductory video. You can make sure that identification is done thoroughly by consensus procedures (3 interviewers have to agree on the identity of the person, and if one disagrees with majority he gets penalty).
You can eliminate those who try to create more then one account via simple face recognition software (plus some extra mining-interviewing). But I believe that this is unnecessary. Blockchain is about having as many identities as you want.

There is a great development that can solve a lot of problems and can open the door to new features, I am trying to figure out if there is a way to build this feature.
The idea is to build an "hash" to identify a real person. There must be 3 property.

1) for every human must be a unique hash id
2) it is not possible to build this hash id without the real person ( it is not possible to build in an automatic way these id)
3) decentralized , without a certifier authority

For example a not working solution can be something related to the dna code , build an hash from the dna but violate the point 2 because is possible to build in automatic false hash id ...

Any idea for a solution?

Maybe if you build and DNA reader in your computer, you just have to lick a stick and put it into the devise, so there is the one possibility, but, of course anyone can steal your DNA information from a cup of coffee , for example…

But the point should be… Why? In the world of control and lack of privacy building a new system of recognition… is there any point in doing so? And… as for crypto, it is not supposed to be anonymity the whole point of its existence? (even since they are not).

I am not judging here, I´m just really curious about the idea behind this.
