Image and Video Metadata and Verification Tools
Image and Video Metadata and Verification Tools[edit | edit source]
Analyzing digital files to uncover origins, authenticity, and context.
Overview[edit | edit source]
Image and video metadata and verification tools help activists, researchers, and journalists validate the authenticity and context of media. This is essential for countering misinformation, documenting human rights abuses, or verifying events when trust in official narratives is low.
Digital media often contains hidden metadata — embedded information like date, time, GPS location, camera model, and software used — which can be analyzed to:
- Confirm time and place
- Detect tampering or manipulation
- Track media distribution or re-use
- Support investigations with verifiable data
Types of Metadata[edit | edit source]
- EXIF: Exchangeable image file format, stores GPS, timestamps, camera settings
- XMP / IPTC: Metadata for copyright, author, and usage rights
- Container Metadata: Found in video files (e.g. .mp4, .mov), includes resolution, codec, creation time
Common Tools[edit | edit source]
- Exiftool: Command-line tool to extract and modify image/video metadata
- Metadata2Go / EXIF.tools: Web-based viewers (no install required)
- YouTube DataViewer (Amnesty): Extracts thumbnails and upload timestamps
- InVID / WeVerify Plugin: Browser extension for video verification (reverse image search, keyframes, metadata analysis)
- Fotoforensics: Offers ELA (Error Level Analysis) and basic metadata parsing
Use Cases in Activism[edit | edit source]
- Verify timestamp/location of police violence or environmental destruction
- Compare multiple uploads of the same footage to track virality or manipulation
- Detect if a photo was taken during a different protest than claimed
- Build a case archive with credible metadata-verified documentation
Best Practices[edit | edit source]
- Always preserve original files — avoid social media compression when possible
- Store metadata copies separately when posting online (platforms strip metadata)
- Verify with cross-source triangulation (not just metadata)
- Annotate findings when sharing to maintain transparency
Ethical Considerations[edit | edit source]
- Metadata can reveal personal info (e.g. location) — be cautious with sharing
- Don’t publish identifying EXIF from vulnerable witnesses without consent
- Balance transparency and safety when posting metadata-rich content
- Clearly label analysis results as interpreted, not absolute proof
Limitations[edit | edit source]
- Most social platforms strip metadata on upload
- Metadata can be faked or edited
- Not all cameras embed GPS/time info (especially older or privacy-focused models)
- Tools like ELA are not foolproof — false positives are common
