Explore secure media provenance through the Content Credentials specification from C2PA in this 55-minute conference talk from NDC Manchester 2025. Learn how traditional TLS-protected origin trust models have become insufficient in today's centralized internet landscape, where platforms host vast amounts of user-generated content that can be manipulated without requiring HTTP man-in-the-middle attacks. Discover the architecture of the C2PA Content Credentials specification and understand how it addresses modern content authenticity challenges. Examine typical media workflows and implementation challenges while diving deep into validation mechanisms and long-term signature systems within the specification. Gain insights into C2PA's new Conformance Program, designed to provide security assurance levels for C2PA implementations, ensuring robust content provenance verification in an era where digital media authenticity is increasingly critical.
