C2PA standard: verify AI content provenance

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.
