A New Approach to Digital Identity 
Anchored in Physical Reality

— Today’s identity systems are portable
— Passwords, tokens, and sessions can be stolen or replayed
— Attackers don’t  break systems—they impersonate trust

A different foundation is emerging:
— Identity anchored in device physics and ambient signal interaction
— Not stored. Not transferable. Fundamentally resistant to replication.

Device → Ambient Signal → Unique Signature → Authentication
