Executive Summary

Palma is a decentralized identity (DID) protocol designed to resolve the fundamental conflict between Security and Convenience in the digital world. Our core technology, Camera-Based Palmprint Biometrics, transforms a user's unique palm into an unforgeable cryptographic key.

Our philosophy is built on two commitments:

  1. Biometric Cryptography: We utilize a "Biometric-to-Key" derivation process. The user's palm is scanned, converted into a cryptographic key, and the original biometric data is immediately and permanently discarded. We never store raw biometric data.
  2. Zero-Knowledge Proofs (ZKP): All authentication is privacy-preserving. Users prove their identity without ever revealing their private key or biometric data to any party.

The Palma Wallet is our flagship product: an "All-in-One" application for managing DID, Verifiable Credentials (VCs), Crypto Assets, and Decentralized Data. It is a "seedless" wallet, secured by a novel combination of Palmprint Biometrics and Multi-Party Computation (MPC).
