ARD ensures content provenance with C2PA and AWS

This article describes how ARD, Germany's public broadcaster, implemented a serverless solution using AWS and C2PA standards to verify video content authenticity and combat digital misinformation.

• ARD developed serverless media supply chain using C2PA standard for content authentication
• Solution uses Amazon S3, AWS Lambda, and AWS KMS for secure content signing
• C2PA attaches cryptographically sealed manifests tracking content origin and modifications
• Lambda functions automatically generate C2PA signatures when content arrives in VOD platform
• Enhanced hls.js player performs frame-by-frame verification during playback
• Verification status displayed via indicator; red alert and pop-up shown if verification fails
• Serverless approach enables cost-effective scaling with minimal maintenance overhead
• Solution accessible to broadcasters of all sizes without massive infrastructure investment

ARD's implementation demonstrates how cloud-native services and C2PA standards create practical, scalable content authentication for trustworthy media distribution.
