" 🖐 ✦ 🇨🇳 " Let's all think about a question first:

In Web2, facial recognition is more prevalent, and its technology is far superior to palm print recognition. But why does the Humanity Protocol focus on palm print recognition instead of facial recognition?

Today, let's have a good talk about the secrets behind this 🧵:

⛀Humanity Protocol Palm Print Recognition:

Based on the unique patterns of palmprint ridges and palm vein structures. Palmprints contain complex lines and textures, while palm veins reflect the subcutaneous vascular structure, making them difficult to replicate.

Humanity Protocol uses dedicated devices to scan the palm prints and palm veins of both hands, combining zero-knowledge proof technology to verify the authenticity of identity without storing complete biometric data.

Advantages: Palm print and palm vein data are highly personalized, have strong stability, and are not affected by external environments (such as lighting or facial expressions).

⛀Regular Face Recognition:

Identity verification is performed by analyzing facial feature points such as the distance and shape of the eyes, nose, and mouth.

Relying on the camera to capture images, factors such as lighting, angle, makeup, and glasses may affect the accuracy.

Data is usually stored as feature vectors, but can easily be deceived by high-resolution photos, videos, or 3D masks.
(For example, KYC from certain exchanges and project KYC have all been compromised.)

●Difference in Privacy:

Many people in Web3 are unwilling to disclose personal appearance information, while the Humanity Protocol ensures that the verification process does not expose the original palm print data through zero-knowledge proof technology, only outputting "true/false" results.

The lack of information about personal appearance aligns well with the decentralized concept of Web3.

Facial recognition speaks for itself; it is directly related to personal appearance, has a high risk of leakage, and is also prone to abuse.

Finally:
Humanity Protocol, with the complexity of palm prints and palm veins and the privacy protection of zero-knowledge proofs, can certainly find its place in the future of Web3 based on the two points I mentioned above.

Recently, we also acquired MoonGate, which is a significant step forward! The app will be launched soon! Is $H coming soon as well?
