Technical Specifications of C2PA

Architecture and Design

The C2PA framework is built on a set of core components designed to ensure the secure and reliable verification of digital content. The architecture includes the following key elements:

1. Provenance Model: Defines how provenance information is structured and stored, enabling the tracking of content history from creation to dissemination.
2. Trust Model: Establishes the mechanisms for verifying the identity of content creators and publishers, ensuring that provenance information is reliable and trustworthy.
3. Claim Model: Describes the types of claims that can be made about content (e.g., creation date, creator identity) and how these claims are managed and verified.
4. Binding Techniques: Ensures that provenance information is cryptographically bound to the content, preventing unauthorized alterations and ensuring the integrity of the provenance data.

These components work together to provide a comprehensive solution for content provenance and authenticity, facilitating the adoption of C2PA standards across various digital media platforms.

Establishing Trust

Central to the C2PA framework is the establishment of trust in digital content. The trust model involves the use of cryptographic signatures to verify the identity of content creators and the integrity of their contributions. When a piece of content is created or modified, a digital signature is generated using the creator’s unique cryptographic credentials. This signature is then included in the provenance data, providing a verifiable link between the content and its creator.

To ensure the credibility of these signatures, C2PA relies on Certification Authorities (CAs) that perform real-world due diligence to verify the identities of content creators. These CAs issue digital certificates that authenticate the identity of the creator, adding an additional layer of trust to the provenance data. This system enables consumers to confidently verify the authenticity of digital content and trust the information provided in the provenance data.

Claims and Assertions

Claims and assertions are fundamental concepts in the C2PA framework. A claim is a statement about a piece of content, such as its origin, creator, or the modifications it has undergone. These claims are cryptographically signed by the entity making the claim, ensuring their integrity and authenticity. Assertions are collections of claims bound to a specific piece of content, forming the provenance data.

The process of creating and managing claims involves several steps:

1. Creation: Content creators generate claims about their content, such as metadata, creation date, and location.
2. Signing: These claims are digitally signed using the creator’s cryptographic credentials, ensuring their authenticity.
3. Binding: The signed claims are then bound to the content, forming a tamper-evident link between the content and its provenance data.
4. Verification: Consumers and applications can verify the claims by checking the digital signatures and ensuring the provenance data has not been altered.
5. This structured approach to managing claims and assertions ensures that the provenance data remains reliable and verifiable throughout the content’s lifecycle.

Binding to Content

Binding provenance data to content is a critical aspect of the C2PA framework. This binding ensures that any changes to the content are detectable, preserving the integrity of the provenance data. There are two main types of bindings used in C2PA: hard bindings and soft bindings.

1. Hard Bindings: These create a cryptographic link between the content and its provenance data, making any alterations to the content or data immediately detectable. Hard bindings are highly secure and are used for content where integrity is paramount.
2. Soft Bindings: These are less stringent and allow for some modifications to the content without invalidating the provenance data. Soft bindings are useful for content that may undergo minor, non-substantive changes after its initial creation.

Both binding types play a crucial role in maintaining the integrity and reliability of provenance data, ensuring that consumers can trust the content they encounter.

Guiding Principles of C2PA

Privacy and Control

C2PA is designed with a strong emphasis on privacy and user control. The framework allows content creators and publishers to control what provenance data is included with their content, ensuring that sensitive information can be protected. Users have the option to include or redact certain assertions, providing flexibility in how provenance data is managed.

Key principles guiding privacy and control include:

1. User Consent: Content creators must consent to the inclusion of their provenance data.
2. Data Minimization: Only the necessary provenance data is included to maintain privacy.
3. Redaction: Users can redact specific claims to protect sensitive information without invalidating the remaining provenance data.

These principles ensure that the C2PA framework respects user privacy while maintaining the integrity and reliability of the provenance data.

Addressing Potential Misuse

To prevent misuse and abuse of the C2PA framework, a comprehensive harms, misuse, and abuse assessment has been integrated into the design process. This assessment identifies potential risks and provides strategies to mitigate them, ensuring the ethical use of C2PA technology.

Key aspects of this assessment include:
