Real or Fake? Content Provenance Tech to Fight Online Disinformation (G20a)
In an era of disinformation, exacerbated by rapidly advancing AI tools, the creation of seemingly authentic fake content poses significant dangers, including reputational damage and societal harm. Cryptographic provenance technologies are emerging as essential tools for establishing the origin and authenticity of online content.
This talk presents the work of the Coalition of Content Provenance and Authenticity (C2PA), the leading specification adopted by a growing ecosystem of content producers (e.g., generative AI, news media, cameras, photo editors) and validators (e.g., content platforms and social media). It describes how cryptographically signed manifests can be embedded in various types of digital assets to provide secure data origin. The talk also demonstrates open-source tools developed to validate content credentials and introduces novel zero-knowledge cryptographic research that offers stronger security and privacy in C2PA scenarios.
