Abstract: In the age of deepfakes, content provenance is more important than ever to document the authenticity of videos, images, and other digital assets. Until now, there has been no widely accepted standard for documenting provenance in a secure, traceable manner. In 2021, however, the Coalition for Content Provenance and Authenticity (C2PA) released a specification for creating digitally-signed metadata manifests that can be associated with digital assets. The specification requires engineering resources to integrate into test and production workflows, which has been a bottleneck for many media companies that are not sure whether to invest in implementing new technical workflows. Seeking to lower the bar to entry, Amazon Web Services (AWS) developed an easy-to-deploy C2PA solution for Sinclair, Inc., which it has now released for the general public. The solution is deployed using Docker containers and serverless technologies and is invoked via REST APls. This article provides guidance on using the solution to create metadata, action, and ingredient assertions.
