AI impersonation prevention, deepfake resistance, autonomous AI agent identification, postquantum biometric identity generation, continuous session protection against AI agent hijacking, multiorbital identity root-of-trust corroboration, and family fraud elimination. The claims are drawn to methods and systems that make AI-based identity attacks structurally impossible rather than merely computationally difficult, by binding identity verification to the intersection of orbital time — derived from any terrestial or orbital regime — physical hardware, and living biometric presence.
