Interstellar Compliance and Security Architecture Overview
1. Objective
This document outlines how Interstellar's decentralized authentication and behavioral biometric framework aligns with and exceeds major regulatory, security, and identity standards relevant to financial services, mobile authentication, and PII protection.
2. Compliance Alignment Matrix
| Standard | Requirement Type | Interstellar Alignment |
| FIPS 140-3 | Cryptographic module security | Supports use of FIPS-certified Secure Elements (e.g., Titan M2, Samsung eSE). Cryptographic operations confined to SE with attestation support. |
| PSD2 SCA | Strong Customer Authentication | Meets 2FA: Possession (device-bound key + SE attestation) and Inherence (behavioral biometrics + cognitive input). Replay-proof and spoof-resistant. |
| NIST SP 800-63-3 (AAL3) | Authentication Assurance Level 3 | Hardware-backed crypto, anti-replay, biometric spoof resistance. Potential to exceed AAL3 assurance through garbled circuits and behavioral profiling. |
| NIST SP 800-122 | PII protection guidelines | All PII and biometrics are locally encrypted within SE. No central storage. Behavioral biometric profiles are session-specific and AI-unlearnable. |
| ISO 27001 / ISO 27701 | Information Security and Privacy Management | Privacy by design. Secure onboarding, ephemeral authentication state, and no PII leakage. Meets Annex A controls for cryptography and access management. |
| GDPR (Art. 32, 25) | Security of processing, privacy by design | Session-based data minimization, encrypted biometric input, and zero-knowledge user interaction through dynamic cognitive cryptography. |
3. Technical Differentiators
- Dynamic Cognitive Input System: Per-session visual cryptography resists AI-based replay or mimic attacks.
- Garbled Circuits: Ensure ephemeral, non-learnable computation with behavioral biometrics.
- Device Hardware Profiling: Uses execution fingerprinting and SE-based attestation to verify integrity.
- On-Chain SE Signatures: Enables decentralized and verifiable proof of possession without centralized key stores.
4. Strategic Opportunities
- Open Banking & PSD2 Partners: Interstellar provides a future-proof path for banks seeking SCA compliance with user experience advantages.
- EUDI Wallet Compatibility: Can adapt on-chain SE signatures to align with WebAuthn/FIDO2 for compliance with EU Digital Identity Wallet standards.
- MTD/EDR Market Positioning: Behavioral biometric + hardware profile stack can position Interstellar as an advanced Mobile Threat Defense solution.
5. Next Steps
- Create formal FIPS 140-3 SE verification layer for supported devices.
- Define a white-labeled SDK API reference for SCA enforcement.
- Publish internal audit mapping to ISO 27001 Annex A controls.
- Develop technical paper on compliance with NIST AAL3 via decentralized biometric proof.
