Knowledge Base
Technical standards and references behind VeriMedia's AI opt-out and metadata protection workflows.
Core Topics
- AI training opt-out metadata signaling (
ai:opt-out=trueXMP standard) - Creator ownership and licensing metadata (IPTC, XMP WebStatement)
- EXIF and PDF metadata privacy cleanup
How This Is Used
VeriMedia applies these references to keep behavior predictable across JPEG, PNG, WebP, HEIC, and PDF workflows. The goal is practical privacy protection: strip tracking-relevant metadata, retain file usability, and embed creator ownership context where users explicitly request it.
All processing runs in-browser. These sources are used for schema alignment and terminology consistency. no remote API dependency.
Privacy guarantee: VeriMedia never receives your files. All metadata reads and writes happen inside your browser's local sandbox memory. Nothing is uploaded, stored, or logged.
