Mobile Devices

Mobile devices play a crucial role in Interstellar's architecture. They are the interaction surface for every human intent.

World-Leading Mobile Security

Interstellar's Mobile Security Innovation​

Making Your Phone as Secure as a Hardware Wallet​

This technology equips your everyday smartphone with next-generation mobile device security by combining multiple layers of protection in a unique way. Unlike traditional solutions that try to detect malware — which is particularly difficult on mobile devices — this approach creates a secure environment for critical digital actions that remains effective even if your device is compromised.

How It Works​

The system uses 4 strong authentication factors, all working together:

1. Your Device's Hardware Security​

Your phone's built-in Secure Element (SE) stores a special key that's activated by your biometrics — fingerprint or face. This provides hardware-level security similar to what's found in hardware wallets — but conveniently integrated into your daily device.

2. The Intent Message​

When initiating an intent, you see exactly what you're approving — the amount and destination. While this may seem basic, it's presented in a way that malware cannot tamper with or hide, making it a crucial security factor.

3. Dynamic Visual Authorization​

This is where it gets innovative. The system creates a unique cryptographic "movie" that only human eyes can properly see:

  • The “movie” is generated on-chain and contains a one-time code
  • Each frame is protected by advanced cryptography called garbled circuits
  • The code is only visible to humans, not to screen-capturing malware

4. Your Personal Interaction Pattern​

Upcoming Feature: The system will be able to learn how you naturally interact with these visual challenges, creating an anonymous behavioral profile that cannot be stolen or replicated by an AI.

Protection Against Advanced Threats​

This multi-layered security is effective against sophisticated threats. The threat model covers how Proof of Human Intent stops each of them:

  • Scams and Social Engineering
  • Clipper Malware
  • Overlay Attacks
  • Prompt Injection

Breakthrough​

Unlike traditional EDRs, which struggle on mobile, this approach:

  • Is delivered through a simple SDK integration
  • Requires no additional hardware or seed phrases
  • Focuses protection on critical operations
  • Provides security equivalent to hardware wallets
  • Works even on compromised devices

It’s a new paradigm: rather than detecting every threat, it creates a sealed, verifiable environment for sensitive operations that remains trustworthy regardless of device integrity.
