Picture the cameras your city already has — on streetlights, in transit, across offices and clinics, even the phone in your pocket — quietly offered as opt-in wellness sensors. No wearables. No new hardware. Just an early-warning layer for public health, built privacy-first from the very first frame.
Concept illustration. NOZA is a wellness-screening concept, not a medical device — it does not diagnose, and in this vision every alert is verified by a human before any action is taken.
Not surveillance. A consented, anonymized wellness layer that helps a city notice — and respond to — health trends earlier, while keeping every individual invisible by default.
The cameras already around us — streetlights, buses and trains, building lobbies, clinics, a personal phone — can opt in as passive wellness sensors. One tap, or a clearly posted consent zone, is all it takes. Nothing to wear, nothing to charge.
A central health-intelligence dashboard turns millions of anonymized, moment-to-moment wellness signals into one live picture — surfacing early warnings like a flu wave, a heat-stress spike or a rise in cardiac-risk indicators, district by district, before a clinic ever fills up.
Signals are processed on the edge, right next to the camera. Nothing is stored, faces are never kept, and everything is anonymized and opt-in by default. The city sees the shape of a health trend — never a person.
Every alert lands in front of a trained clinician or public-health official first. The AI only raises a hand; people verify the context and decide what — if anything — happens next. No automated action, ever.
Anonymized wellness signals roll up into district-level trends and early-warning alerts. No names, no faces — just the shape of a city's health, updated moment to moment, so officials can act on a rising signal instead of a full waiting room.
A wellness signal moves through five stages — and a person stands between the AI and any real-world response.
An opt-in camera sees a person and reads visible wellness cues — never an identity.
Everything is computed on the device, next to the lens. The raw image never leaves.
Only a stripped, faceless wellness signal — a trend, not a person — is passed on.
A clinician or official verifies the alert and its context before anything happens.
Only once approved does help get routed — a welfare check, a clinic, an outreach team.
For this to ever work in the real world, it has to be governed like public-health infrastructure — not like surveillance software. These guardrails come first, not last.
The AI is a smoke detector, not a firefighter. It can raise an early, anonymized signal — but a trained clinician or public-health official always reviews the context and makes the call. Nothing is dispatched automatically, and false alarms are filtered by people, not code.
The city-scale future is a concept. The technology behind it is real — and you can try the first step right now. NOZA turns the camera you already own into a private wellness check in seconds, with nothing stored.
