A live demonstration of the core principles of Photichain, our patented technology. In four steps you can prove the core claims to yourself:
And an image-block is not limited to photographs of physical objects. Per the patent’s embodiments, the registered image can be an image of data, code, or files; a financial transaction or trade — where a verified match can fire a programmed action of your own design, a transaction being one example; medical imagery such as an MRI or X‑ray; satellite imagery; or your existing UPC barcode or QR code, reprogrammed — the code keeps doing its everyday job for every ordinary scanner while Photichain adds a verification layer only your assigned devices can read.
The core loop — four steps, one protected chain. Registration and reprogramming are both written to the chain of custody; verification and recognition both resolve locally against it. Below the loop: reader gating, field recognition, and challenge tests.
Choose or capture an image. It is fingerprinted on your device and sealed into the chain below as a new image-block, linked to the block before it.
On a phone, this lets you take a photo or pick from your library.Every registered image carries a programmable action that fires on a verified match. Change it any time — the image-block is re-tasked without re-registering, and the change is recorded in the chain of custody.
Present an image. It is checked against the protected chain locally, with no server call. A registered, unaltered image passes and its programmed action executes; anything altered or unknown fails. The few milliseconds shown is browser overhead on a general-purpose CPU — a ceiling, not the target. In firmware on a DPU it is engineered to run far faster.
This takes an image you registered, changes a single pixel, and runs the same verification. The altered copy no longer matches its protected image-block — tamper-evidence in action.
A protected image-block is cryptographically unreadable to unassigned devices — you decide which hardware holds the key. Toggle provisioning below (simulated for this demo), then attempt a read as this browser: first without the key, then with it. The anti‑enumeration consequence matters as much as the security one — to everything you have not assigned, your protected assets yield nothing: no identity, no data, no inventory intelligence.
Display one of your registered images on another screen — or print it — then capture it with your camera, filling the frame. Recognition is approximate by design: it tolerates lighting, angle, and framing differences, the way a field sensor recognizes a marker it has seen before. On a recognized match, the programmed action executes. This demo uses simplified visual matching to illustrate the principle — in the full patented architecture, recognition is specified as AI-driven computer vision, engineered to recognize markers under far harder real-world conditions.
On a phone, tap to take a photo or pick from your library.Verification here is two-layered by design: an exact layer (Step 3) where changing a single bit fails, and an approximate recognition layer (Step 6) that tolerates real capture noise while rejecting different content. These challenges show where each layer draws its line — run them and watch the system explain its own boundaries.
Each block below is sealed against the one before it. Registrations and reprogramming events are both recorded, so re-tasking an image-block never breaks the custody trail.
What you just used is the floor, not the ceiling. Every capability on this page scales up in the production architecture:
This page runs in a sandboxed browser. The production architecture is firmware-resident on the DPUs and SmartNICs you already own — designed to verify at the hardware boundary, at the point of capture.
Recognition here is deliberately simple. The patented architecture specifies AI-based computer vision — built to recognize registered images through the lighting, angles, and distances of real field conditions.
You reprogrammed one image-block over the air. The same patented capability is designed to re-task verification logic, identities, and triggered actions across an entire deployed fleet — with no recovery, no replacement.
This browser demo is the floor — the simplest public expression of Photichain. Response Images has also built and exercised an enterprise-scale prototype on enterprise cloud infrastructure, running one-way (point-of-capture) and two-way (round-trip) verification pipelines — the program behind the consensus-free architecture presented across this site. Full instrumented benchmarking is the current milestone.
