Questions this topic helps answer
Technical clues are strongest when their purpose and failure modes are explicit. Metadata can be edited; hashes answer different questions; provenance records need validation.
IPTC and XMP
Descriptive, administrative, rights, and workflow metadata used by publishers and creators.
SHA-256
A byte-level fingerprint that changes when any file byte changes.
Perceptual hash
A compact visual fingerprint designed to remain somewhat similar after ordinary transformations.
Content Credentials
Cryptographically verifiable provenance assertions about creation and editing history.
Choose the technical signal by the question
Use the Image Metadata Checker to record available fields and a SHA-256 fingerprint. The image hash guide explains when perceptual hashes are more useful for resized or recompressed files, while signed provenance credentials describe asserted history and whether the credential validates.
Absence is usually inconclusive
Platforms commonly remove metadata during upload or recompression. Screenshots and copied files may not retain the original fields. A missing camera model does not prove an image is synthetic, and missing Content Credentials do not prove that a file is deceptive.
Record the file before interpretation
Keep an untouched copy, calculate a cryptographic hash, and note the acquisition URL and time. Export technical results separately. This establishes which file was examined and prevents later edits from being confused with the source artifact.
Apply this topic with Image Metadata Checker
Inspect file metadata and create a SHA-256 fingerprint without storing the upload.
