Deepfake, Image and Video Forensics

Is a photo or video genuine, edited or generated by AI? We examine the file, where it came from and how it was made, and report what can be established about its authenticity, with the limits of each test stated plainly.

How We Test Authenticity

Metadata and ProvenanceCamera, device and software details, capture time and location, and Content Credentials (C2PA) where present.
Source and HistoryFinding the earliest available copy and tracing how the file was shared, re-saved and re-encoded.
Compression AnalysisSigns a file has been re-compressed, spliced or exported from editing software.
Pixel and Noise InconsistenciesLighting, shadows, edges and sensor noise that do not match across the image or frame.
Frame-Level Video AnalysisDropped, duplicated or inserted frames, and face, lip-sync and motion artefacts typical of AI generation.
Device ComparisonWhether a file is consistent with the phone or camera it is claimed to have come from.

When It Matters

  • →Fake or manipulated intimate images, including image-based abuse
  • →Photos or video produced as evidence in family law and protection order matters
  • →Disputed CCTV, dashcam and body-worn footage
  • →Impersonation scams using a fake video of an executive or family member
  • →Defamation and harassment involving fabricated images
  • →Insurance claims supported by edited or recycled photos

Accuracy and Limits

No single test proves an image is real or fake, and automated deepfake detectors give probabilities, not answers. We combine several independent methods, report the confidence of each finding, and state what the evidence cannot establish. A heavily compressed copy from social media holds far less information than the original file, so we always ask for the earliest version available.

If you are dealing with intimate images shared without consent, you can also report it to the eSafety Commissioner, who can have material removed.

Common Questions

Can you tell if a photo or video is fake?+

Often. We examine the original file, its metadata, compression history and visual consistency. Some findings are conclusive; others can only be reported as consistent or inconsistent with editing.

Do you need the original file?+

It helps a great deal. Files forwarded through messaging apps or social media lose metadata. Send the earliest copy you have and tell us where it came from.

Can AI detection tools settle the question?+

No. Automated detectors produce false positives and false negatives. We use them only alongside file and source analysis, and explain their limits in the report.

Before You Call

01Keep the Original FileSave the file itself, not only a screenshot or screen recording. Screenshots strip most of what we test.
02Record Where You Found ItThe link, account, date and time, and who sent or posted it. Take a screenshot of the post as well.
03Don’t Edit or Forward ItCropping, filtering or re-sending through a messaging app re-compresses the file and loses detail.
04Keep the DeviceThe phone or camera said to have taken it lets us test whether the file is consistent with that device.
