Federated Matching Process

The SyncID Federated Identity Matching process enables the system to match a user’s collective identity data (biometrics, social accounts, and blockchain addresses) against a broader database of credentials to verify identity across multiple platforms. With user authorization, the system uses zero-knowledge set membership on SyncID to allow Web2 applications, any blockchain, Layer 3 applications (L3s), and decentralized apps (DApps) to securely identify users.

Let's understand it through an example: Bob and Alice are both registered on SyncID. Their identities include the following attributes:

{
  "Bob": {
    "ADA_Address": "addr1qyrhfdkidh....",
    "Twitter_ID": "@bob_in_crypto",
    "Telegram_ID": "@Bob_Tele",
    "Biometric_Hash": "hash123"
  },
  "Alice": {
    "ADA_Address": "addr1thu7ghcndkjd...",
    "Twitter_ID": "@alice_in_chain",
    "Telegram_ID": "@Alice_Tele",
    "Biometric_Hash": "hash456"
  }
}

Bob and Alice can now seamlessly pay or chat with each other on Telegram or Whatsapp through their ADA address, tip on Twitter using SyncID-linked social profiles, receive notifications from dApps they interact with and much more.

This process ensures user privacy while offering a reliable means of authenticating identities across a secure, distributed network. By incorporating biometric data, social profiles, and blockchain addresses, SyncID provides a comprehensive and decentralized identity management solution ideal for the Web3 ecosystem and beyond.
