Guardian Wallet & Steganographic Ticketing
Overview
A companion guardian device for Quantum Vault that co-signs high-value transactions, provides account recovery, and verifies steganographic event tickets. Built with post-quantum cryptography (ML-KEM-768, ML-DSA-65), Shamir Secret Sharing, and multi-layer LSB steganography. Pairs securely with Quantum Vault via QR, Bluetooth LE, or relay.
Features
- Guardian Pairing: Secure device-to-device pairing with Quantum Vault wallets via QR code, Bluetooth LE, or relay server. Verbal verification codes prevent MITM attacks.
- Transaction Co-Signing: Real-time approval requests for high-value transactions with detailed summaries, 15-minute expiry, and replay protection via nonces.
- Steganographic Ticketing (zsss): Embed up to 256 unique event tickets in a single image using multi-layer LSB steganography. ChaCha20-Poly1305 encrypted, publicly shareable images.
- Shamir Secret Sharing (SLIP-39): Split wallet recovery seeds into M-of-N shares with threshold recovery. BIP39-compatible word lists for human-readable backup.
- NFT Photo Signing: Two-layer steganographic NFT system — public certificate for verification, private ownership key as a bearer instrument. No blockchain required.
- Post-Quantum Security: ML-KEM-768 and ML-DSA-65 for quantum-resistant guardian pairing and transaction signing, combined with Ed25519 and X25519 classical cryptography.
