Plain-language guides to image protection, provenance, and documentation — written for artists, not engineers.
Guides
What copyright protection means — and doesn’t
What registering your work actually establishes, and the honest limits of any technical protection.
ReadWhat a timestamp establishes — and doesn’t
Why a timestamp is evidence of existence, not proof of ownership or originality.
ReadCryptographic hashes, in plain language
A fingerprint for one exact file — and why it changes the moment the file does.
ReadPerceptual fingerprints, in plain language
Recognizing visually related versions even when the exact file has changed.
ReadRights metadata, and why it isn’t durable on its own
IPTC/XMP rights fields — useful, and often stripped by the platforms that receive your work.
ReadContent Credentials (C2PA), clearly
Verifiable provenance information — what it documents, and what it doesn’t prevent.
ReadSharing images more safely
Derivatives, sizing, and the small choices that keep authorship travelling with your work.
ReadDocumenting unauthorized use, calmly
How to preserve evidence without rushing to accusation.
ReadProtection methods, in detail
Every method, with the same honest structure: what it is, what it does, and what it doesn’t.
Cryptographic hash
A fingerprint for one exact file, computed with SHA-256.
Perceptual fingerprint
A compact description of what an image looks like, rather than its exact bytes.
Rights metadata
IPTC/XMP-compatible fields embedded in the file — creator, copyright notice, usage terms, and links.
Visible mark
A watermark or corner mark rendered onto a derivative image.
Invisible watermark
A resilient identifier embedded in the pixels of an image, imperceptible to the eye.
Content Credentials (C2PA)
A tamper-evident standard for attaching provenance information to media.
