1. AICD and C2PA
C2PA belongs to the family of technical standards for content provenance and authenticity. Built on X.509 certificates, digital signatures, and hash binding, it provides cryptographic verification of a piece of content's provenance, edit history, and integrity. It addresses rich media such as images, video, audio, and PDF, and the barrier to adoption lies in compliant implementation and a chain of trust. AICD, by contrast, is a voluntary disclosure framework for the degree of AI involvement. It records the A0–A5 level of participation, human review, and tool information through human-readable statements and optional machine-readable fields; it offers no technical verification or certification endorsement; it applies to a broad range of content types, text included; it relies on the publisher's good faith; and it explicitly does not replace mandatory labelling. Put simply, C2PA answers "can the source be trusted, and is it tamper-proof", while AICD answers "is AI involvement transparent".
2. Why an "initiative"
Here "protocol" means a binding agreement or a normative framework. AICD has no contracting parties, no signing procedure, no compliance audit, no certification mechanism, and no liability for breach, and it constitutes no legal, regulatory, or platform obligation. It takes the form of voluntary, open, low-threshold, soft-law governance: anyone may adopt or withdraw from it unilaterally, with no authorisation, registration, or payment required, and those who do not adopt it face no penalty asserted by AICD. AICD draws its force from good faith, consensus, and reputational mechanisms rather than from enforcement; its aim is to cultivate a culture of transparency in AI creation, not to establish a mandatory standard or a certification system. It is an initiative for exactly that reason: it offers a choice and a shared vocabulary, and imposes no obligation.
