Digital forensics is the technical analysis of digital media and metadata to determine the authenticity, provenance, and integrity of digital evidence. In the misinformation context, digital forensics includes image authentication, video analysis, metadata examination, and detection of AI-generated or manipulated content.
Scope
- Image authentication: Detecting manipulation, determining origin, and verifying timestamp and geolocation using metadata and computational analysis.
- Video forensics: Analyzing frame-level artifacts, compression patterns, and audio-visual consistency to detect deepfakes and synthetic content.
- Metadata analysis: Examining EXIF, timestamps, and other embedded information to verify content origin and authenticity.
- Manipulation detection: Identifying signs of editing, splicing, or synthetic generation in digital media.
- Chain of custody: Documenting the integrity of digital evidence for investigative and legal contexts.

Notes
Digital forensics has become increasingly important as AI tools make high-quality image and video synthesis accessible to non-experts. The field bridges academic research in computer vision with practical needs of journalists, fact-checkers, and law enforcement.
