Because our eyes deserve trusted content.
Oberchain is a C2PA suite that certifies the origin and integrity of digital content with CA/TSA-backed signing, timestamping, and provenance. With Generator, Validator, APIs, and AI-based watermarking, it ensures authenticity and compliance across Embedded/Sidecar/Remote modes—from creation to screen.
Oberchain Services
Generator / Verifier
Oberchain’s Generator creates cryptographically signed C2PA manifests embedding origin, authorship, and edit history.
Supports all C2PA modes: Embedded, Sidecar, and Remote—choose in-file credentials, a local sidecar, or remote-referenced manifests.
The Verifier checks authenticity and integrity across all three modes, ensuring every asset carries a verifiable chain of trust from creator to audience.
CA, TSA and Vault
CA/TSA issues X.509 certificates and RFC 3161 timestamps to secure content signatures and ensure long-term verifiability.
The Vault is a secure repository for remote manifests only, providing a stable access point for verification—no key or policy management.
Together they enable policy-driven trust, revocation control, and EU AI Act–ready compliance across C2PA workflows.
Deployable Everywhere
Oberchain supports multiple deployment models—SaaS, Hybrid, and On-premise—to match different security, latency, and compliance needs.
Integration is seamless through REST APIs, SDKs, or managed appliances, enabling quick adoption in existing media or data workflows.
All deployments ensure scalability, observability, and SLA-backed reliability for both file-based and streaming use cases.
Ensuring Compliance with the EU AI Act
Oberchain is designed to ensure full compliance with Article 50 of the EU AI Act, which mandates transparency and traceability for AI-generated or AI-modified content.
By embedding C2PA manifests, cryptographic signatures, and verifiable provenance data directly into media assets, Oberchain provides the mechanisms required to label, audit, and verify content origin and integrity.
AI-Driven Content Fingerprinting for Provenance Integrity
Oberchain’s Fingerprinting module creates a unique digital signature for every media asset, enabling precise identification even after editing, transcoding, or redistribution.
Using robust perceptual hashing and AI-assisted analysis, it links content to its original C2PA manifest, allowing verification even when metadata is lost or altered.
This ensures persistent traceability across platforms and workflows, reinforcing authenticity and provenance throughout the content lifecycle
Built on C2PA. Powered by Kebula.
Oberchain is a spin-off initiative of Kebula S.r.l., created to extend Kebula’s expertise in data-centric and AI-driven solutions into the domain of content authenticity and provenance. Kebula is a contributor member of the C2PA consortium, actively helping evolve the open standard for trusted media. Through Oberchain, Kebula turns this commitment into a practical, enterprise-ready suite that enables organizations to generate, verify, and preserve trusted digital content across the entire media lifecycle.
