OpenCV 5 · Agentic privacy · AWS

Share the safe copy.

QuietGuard Vision finds faces, QR codes, and text geometry before a screenshot becomes public. It preserves the source, creates an opaque redacted copy, and verifies every action.

Copy-only action

The original stays intact.

The fixture is generated synthetic data. The sanitized copy replaces QR and text regions with opaque pixels, then a separate verifier checks that each selected region materially changed.

Bounded autonomy

A visible decision chain.

Every stage emits machine-readable evidence. High region count or coverage stops at a human review gate.

Perceive

OpenCV 5 uses QRCodeDetector, YuNet, thresholding, morphology, and contours.

Decide

A deterministic policy scores signal type and image coverage.

Act

The agent writes a new file. It never overwrites the source.

Verify

Pixel change and a hash-chained trace prove what happened.

Cloud delivery

One pipeline, local and AWS.

The same tested package runs behind an HTTP API in an arm64 Lambda container. The function has only the basic logging role, caps input at 5 MiB, and keeps request data in temporary storage.
