Open-Source and Online Evidence: Capture and Verification
Readiness training. LEA.Training does not grant any official certificate, licence or authority.
A public post, a video, a web page, a seller's listing. Anyone can see them, and anyone can save them. That is the strength of open-source material and also its weakness. A page can change in a minute. A screenshot can be edited in less. This unit shows how to capture online material so that it can be trusted later, and how to test it before you rely on it.
Focus: capture it so that another person can check it. Then verify it before you believe it.
Learning objectives
- Follow four steps: plan, collect, preserve, verify.
- Make a capture record that supports a web page or post as evidence.
- Explain the weaknesses of a screenshot and how to strengthen it.
- Use a web archive, and state its limits.
- Verify online material by its source, its content and its technical data.
- Work safely and within the law and the platform's terms.
