Check provenance in an image-resize pipeline

When to use this guide

A site serves a credentialed original through its download link but strips metadata from responsive image variants.

This is a fictional implementation scenario. The procedure below is Article 50 Hub's suggested working method, not a prescribed legal form, a customer result or a claim that every step is an additional statutory requirement.

Review procedure

1. List the master asset and the generated size variants.

2. Fetch representative delivered variants from the actual rendering path.

3. Inspect each with the documented validation tool and record format limitations.

4. Review how the pipeline preserves or re-establishes appropriate provenance without inventing a history.

What the example review finds

• The full-size image retains credentials.

• The thumbnail and mobile variant do not expose the same record.

Keep these example observations separate from your own results. An unknown or untested state should stay open until the relevant evidence has been inspected.

Fields for your working record

• Master asset

• Variant dimensions

• Delivery URL

• Validation result

• Pipeline owner

Use the downloadable blank worksheet linked on this page to connect the observed behavior with the deployed system. Add a reviewer, date, evidence reference, unresolved questions and a next action. The worksheet is editable locally and does not upload your records to Article 50 Hub.

Completion and handoff

Close the task only for the scope actually reviewed. Preserve the result that another authorized reviewer can reproduce, identify the owner of remaining work, and record a retest when the implementation changes. A completed worksheet is not a substitute for the underlying evidence.

Decision boundary

Derived-asset provenance requires technical design and review; copying a claim is not equivalent to a valid derivation record.

The official references below provide legal or technical context. Resolve applicability and exception questions with the responsible qualified reviewer; use the product's tools to organize implementation work within that assessment.
