Security & Privacy

RealiOS is designed with defense-in-depth architecture, securing user data at every layer.

1. Encryption

All sensor data is encrypted on-device using AES-256-GCM, and only hashed identifiers are stored on-chain.

2. Authentication

Every submission requires:

• Wallet signature

• Device key validation

• Nonce (anti-replay protection)

3. Privacy

• GPS coordinates blurred within a 3–5 km range

• Motion or sound data abstracted into statistical form (no raw media)

• Zero-knowledge proofs for submission validity

4. Sybil Resistance

• Unique node ID tied to wallet + device hardware

• Optional staking or delegation for higher trust missions

• Cross-validation among nearby nodes to detect data forgery

5. Immutable Proof-of-Data

Once verified, every data hash is permanent on Solana — guaranteeing tamper-proof, timestamped authenticity forever.
