How Biometric Proof-of-Humanity Works

This page describes the concept of SSI and how biometrics can empower humans to be fully autonomous when it comes to owing their own data.

Humanity is building out a global infrastructure for human-based Self-Sovereign Identities (SSI), referring to decentralized identity models that provide users with full control and autonomy of their own identity data.

To ensure Proof-of-Humanity (PoH), Humanity uses two methods:

1. Enrollment App: Available on both Android and iOS, it allows users to scan their palm print capturing the surface patterns of the palm to receive a palm print Verifiable Credential (VC) using a CNN machine learning model.

2. Humanity Scanners: Hardware devices that use infrared light to map the unique vein patterns beneath the skin. These vein patterns are only detectable in a living body, making them impossible to replicate and one of the most secure identification methods available.

The mobile app provides a basic yet robust Proof-Of-Humanity within Humanity while the activation through the Humanity Scanners provide a full enrollment.

In both cases Humanity keeps personal data entirely confidential due to the implementation of Zero-Knowledge (ZK) Proofs.
