Legal and regulatory developments: transparency, copyright, and deployment controls

EU AI Act Article 50 transparency duties have applied since 2 August 2026; further watermarking rules are expected by 2 December, with provider/deployer roles and system eligibility requiring careful interpretation. A practical guide recommends mapping tools and regions and planning machine-readable marking and explicit deepfake disclosure. C2PA manifests differ from probabilistic embedded watermarks; no mark alone proves authenticity, and disputed portfolio claims show why signals should not be treated as definitive evidence.
