Understanding C2PA Provenance Architecture
The Coalition for Content Provenance and Authenticity (C2PA) standard embeds tamper-evident metadata into image headers using JUMBF container structures.
- Detection of JPEG APP11 markers and embedded JUMBF boxes
- Inspection of assertion claims: c2pa.actions, com.adobe.generative-ai
- Structural detection of Content Credentials across PNG and WebP
Forensic Scope & Structural Inspection
MetaClean provides immediate local structural detection to reveal whether provenance manifests are embedded in the file headers.
- Reveals embedded signing certificate subjects and issuers
- Extracts recorded actions (e.g. creation, cropping, generative editing)
- 100% private in-browser analysis without external API dependencies
Zero-Server Architecture
100% Client-Side Privacy Guarantee
Your browser loads the image binary directly into local memory via JavaScript File API.
Metadata extraction and cleaning algorithms execute on your device CPU with zero network transfer.
The sanitized file is saved straight to your downloads folder without touching any remote server.
