Biometric identification and privacy protection have always been the core challenges of Web3 identity verification. The AIBT solution is worth noting — by combining zero-knowledge proofs and homomorphic encryption, it achieves a bold breakthrough: your fingerprint, iris, and facial data never need to be stored or transmitted.

The technical principle is actually not complicated. AI performs identity matching and liveness detection, but all processes are conducted within an encrypted environment. After verification, only the "identity hash value" is written to the blockchain. In this way, users have a unique and unforgeable digital identity across the entire Web3 world, while also completely avoiding the privacy leak risks caused by attacks on centralized databases.

To put it simply, this addresses not only identity issues but also trust issues. Your private data is always in your control, with only verification results recorded on the chain — this is the true meaning of decentralized identity.

Hmm, this idea is interesting. Not putting data on the chain indeed solves the privacy issue for the majority, and it's much more reliable than previous schemes that involved throwing everything onto the blockchain.

honestly the zero-knowledge part sounds clean on paper but... where's the independent audit trail? ngl seeing "never stored or transmitted" claims makes me twitch a little, requires further validation imo

I think this approach is really clean; only putting the hash value on the chain without the data itself is a brilliant move. Finally, someone thought of using homomorphic encryption to handle this... but how does it perform in practice? Zero-knowledge proofs sound very appealing, but can the verification cost on the chain really be acceptable? If this really works out, the KYC process used by centralized exchanges will be shattered into pieces. It seems much more reliable than those fake privacy projects; data truly cannot be accessed by anyone. But the key question is whether anyone will actually use it... even the best solution is useless if no one adopts it. On-chain biometric verification has always been a big pitfall, but this time it finally looks interesting. Will the user experience become more complicated? That’s the real test. The issue of private key management is solved, but the problem of biometric data arises again—going in circles.
