Human Presence Infrastructure™
A real-time infrastructure layer that verifies human presence in AI interactions


Human Presence Infrastructure™ verifies presence as it unfolds
Not identity
Not language
Not biometrics
HPI evaluates patterns in human expressive signals to distinguish human-generated expression from synthetic or replayed signals
Identity = who I am
Semantics = where I am
Expression = how I am
Sound = here I am
Intono introduces the fifth layer
Presence = that I am
Where Human Presence Infrastructure™
sits in the AI stack:
Identity layer
Authentication, biometrics, speaker identity
Semantics layer
Language processing, meaning, intent
Sound layer
Acoustic signal and vocal behavior
Expression layer
Continuity of human expressive dynamics
Human Presence Infrastructure™
Foundation layer
Verification of ongoing human presence in real time
