The only way to check if a given fingerprint belongs to someone real is to meet him in person and verify it by his finger.
So 3DPass is not a digital identity because 1 person can have infinite amount of digital identities. In my opinin, correct me if i'm wrong, it lose majority of use cases.
KK, will do.
pass3d recognition lib must contain both the fingerprint recognition algorithm and 3D object recognition (
Grid2d), which is actually there. That's how it works. It will prevent each digital identity from copying just as it does with 3D objects mined on 3Dpass blockchain (every object has a unique shape). Like 1 object = 1 asset.
1. As you can see on the picture posted by
@3dpass, the HASH ID is created from several pieces of data when together being leveraged as a seed. But each of them represents an
authentication factor you can never recover the HASH ID without having all of them:
- a fingerprint is
something that you are factor, which can identify the person easily (of course, in person);
- a piece of stone is
something that you have factor.
- this combination might be expanded with some additional factors like a password (
something that you know), etc.
So 3DPass is only a more secured version of private key. Or maybe not "more secured" but "secured in a different way". Because you can also hash your private key using "something you know" AKA password and part of your best book as "something you have" using simple softwere. 3DPass is nothing more than that. Am I wrong?
Yes, you are. As it was mentioned above,
the recognition algorithm is used in 3dpass instead of standard SHA2 hashing.
I suggest that you read this article to compare and understand better how it protects objects from being copied:
https://3dpass.medium.com/proof-of-scan-consensus-how-does-that-work-7a88b0fc8530that your bio has been already compromised (or even public), but the second factor is private and strong enough to protect your keys.
good point. But that doesn't this fact make bio useless in this system?
It doesn't, cause that's exactly what makes HASH ID real personal digital identity. Bio data serves to identify a person, not to protect your key. Moreover, I'm not sure, your fear to disclose your bio makes that much sense nowdays. In most cases, it's already being public (iris scans on your selfie photos published on the Internet, fingerprints on your camera). Of course, if you want to stay private, you can live your life without making photos, hiding from public cameras with a hood etc... but it's not common.
In my opinion, lots of people would prefer the possibility to use public digital identity for making p2p deals with real assets. Moreover, they would publish their iris scan with its HASH ID, so that 3DPass network can verify its authenticity. That's just my opinion. It doesn't make sense to keep in private something that you can't hide.
