The C2PA standard certifies that text was not generated by AI models like ChatGPT.

An open standard that proves the authenticity and provenance of digital content against the proliferation of generative AI. What is C2PA?: C2PA (Coalition for Content Provenance and Authenticity) is an open standard backed by Adobe, Microsoft, Intel and other major players. It attaches to any digital content, image, video, text, audio, a tamper-proof provenance certificate. This certificate contains cryptographically signed metadata: who created the content, with which tool, when, and whether it has been modified since. Why does it matter now?: With the democratisation of ChatGPT, Gemini, Mistral and other generative models, it has become impossible to distinguish human text from AI-generated text with the naked eye. C2PA offers a technical answer to this trust problem: rather than detecting AI (a fragile approach), it proves the authenticity of human content (a reliable approach). How does certification work?: The process relies on a chain of trust. The author uses a C2PA-compatible tool to create content. At publication time, the tool generates a signed manifest containing the creation history, modifications and the author's verified identity. This manifest is embedded in the file or stored in a public registry. Any subsequent modification invalidates the signature. Practical applications for businesses: For businesses, C2PA opens several use cases: certifying that marketing content was not AI-generated (AI Act compliance), guaranteeing the authenticity of contractual documents, protecting intellectual property of original creations, and reinforcing client trust in official communications. At Powehi: a Labs topic: We are actively exploring C2PA in our Labs. Our goal: offer our clients simple tools to certify their professional content and stand out in a world where digital trust becomes a competitive advantage.
