Provenance, watermarks and labels for AI content
Understand content credentials, watermarks and AI labels: how they work and where they fall short
A taste of a lesson
If an image has no content credentials, does that mean it's fake?
No. Absence tells you very little. Most cameras, apps and platforms do not yet attach or preserve provenance data, and a simple screenshot or re-upload often strips it. So most genuine images have none. The logic only runs one way: valid credentials are useful evidence about origin, missing credentials are neutral. For an unlabelled image, fall back on context checks: original source, reverse image search, other coverage. Quick check: what would you conclude from an image whose credentials say 'generated with AI'?
Written by the teacher as an example. In your lesson the tutor answers your own questions, and like any AI it can be wrong.
What you will be able to do
- Distinguish provenance metadata, watermarks, detectors and visible labels
- Explain how each signal can be stripped, degraded or misread
- Explain why absence of a signal does not prove authenticity
- Design a labelling approach for an organisation's own AI assisted content
Lesson plan
- 1 Four kinds of signal Tell apart provenance, watermarks, detectors and labels. Start
- 2 Provenance metadata in practice Understand signed provenance records and their weak points. Start
- 3 Watermarks and their limits Assess how robust watermarks are for images, audio and text. Start
- 4 Labels and audiences Understand how people interpret AI labels. Start
- 5 A layered approach for your organisation Combine signals and set a clear policy for your own content. Start

About this tutor
For communicators, platform and trust staff, archivists, journalists, designers and policy minded learners who need to understand how the origin of digital content can be signalled. You learn the difference between provenance metadata such as content credentials, invisible watermarks in images, audio and text, detection classifiers, and visible labels. You look at how each can be stripped, forged or misunderstood, why 'unlabelled' does not mean 'authentic', and how layered approaches work better. You also consider practical choices for an organisation: when to label its own AI assisted content, and how to explain labels to audiences.

About the teacher
I teach people to judge AI claims, spot synthetic media and report on AI without the hype
9 tutors 435 lessons taught Sample
I teach media literacy for the age of AI. My learners include journalists, students, sceptics and anyone tired of breathless headlines in both directions. We practise reading claims about AI critically, checking images and video, understanding why AI text detectors fail, and asking the questions a careful reporter would ask. My background is in newsroom fact checking and training reporters,...
