Identity and integrity
Computes SHA-256, identifies JPEG or PNG from header bytes, and reports dimensions independently of the filename.
Image Authenticity & Evidence Checker
Inspect a photo’s hash, true container, dimensions, metadata and editing markers, C2PA/JUMBF signals, entropy, and appended data—then download a branded evidence report.
Evidence warning: No software can prove a photo is “real” from one file. Metadata can be forged, editing can be legitimate, and absence of a provenance credential is not evidence of fakery.
Analyze a JPEG or PNG image
Maximum 10 MB. The API processes the file in memory and does not retain file content. Use only images you are authorized to analyze.
What the analysis checks
Metadata and editing traces
Surfaces EXIF/XMP, camera, software, timestamp, Photoshop/Adobe, ICC, and sparse-metadata signals where readable.
Content Credentials signals
Detects C2PA/JUMBF-style markers while clearly separating marker presence from cryptographic trust validation.
Container anomalies
Finds data after a JPEG end marker, secondary file signatures, and whole-file entropy for deeper review.
Forensic workflow
- 1
Preserve the original and record its SHA-256 hash before editing or converting it.
- 2
Review every note, warning, and error alongside the complete technical facts.
- 3
Corroborate findings with provenance validation, source files, witnesses, and specialist examination when stakes are high.
Frequently asked questions
Can this prove whether an image is AI-generated?
No. It reports structural and metadata evidence. AI detectors and missing camera metadata are probabilistic signals, not proof.
Does a Photoshop marker prove deception?
No. It shows that an Adobe-related marker exists; ordinary cropping, color correction, and exporting can create the same trace.
Does it validate Content Credentials?
The beta detects C2PA/JUMBF-style markers but does not yet validate the cryptographic signature, certificate chain, or issuer trust.
