Imaging Evidence Integrity

Create a portable integrity capsule for healthcare evidence — containing a SHA-256 evidence fingerprint, chain of custody, sequence and public proof receipt, without storing or exposing sensitive healthcare files.

Data postureMetadata + evidence fingerprint only

Plain-English meaning:

GetIntegrityAPI adds the portable proof layer, attaching independently verifiable receipts to healthcare workflows you already run. This capsule shows what was sealed, who sealed it, when it happened, where it sits in the sequence, and how it can be verified later.

5. Canonical sealed capsule

This downloadable capsule is the evidence package used for offline inspection and SHA-256 verification.

6. Offline verification path

Step 1Download the capsule JSON.

Step 2Canonicalize the canonical_evidence object using sorted-key JSON.

Step 3Compute SHA-256 over the canonical evidence string.

Step 4Compare it with the evidence fingerprint shown above.

Step 5Use the proof ID or verification URL to confirm the public proof receipt exists.

Integrity proof only. This demo verifies digital evidence integrity, not clinical accuracy, diagnosis, regulatory approval, or medical meaning. It uses example healthcare payloads only — no real patient data, medical image, raw report, or proprietary file content is submitted or stored.
