OpenAI adopts C2PA, partners with Google on SynthID
OpenAI announced two measures to make it easier to detect images generated by its models: a commitment to the open C2PA provenance standard (metadata flags) and a partnership with Google to embed the invisible SynthID watermark. The protections and a preview public verification tool that checks both signals will initially apply only to images produced by OpenAI products, with the company saying it hopes to expand support over time. C2PA, founded in 2021, provides editable metadata that can be manipulated but is broadly accessible, while Google’s SynthID watermark is designed to persist through common transformations like screenshots and resizing. OpenAI positions the two approaches as complementary layers to improve provenance and resist tampering.
Major AI platforms (OpenAI and Google) are rolling out provenance and watermarking measures and a verification tool; this affects content authenticity, brand safety, misinformation risk, and verification workflows across media and advertising.

OpenAI strengthens provenance with C2PA and SynthID
OpenAI announced a multi-layered approach to content provenance that combines C2PA-conformant Content Credentials, cross-platform SynthID watermarking (via a partnership with Google DeepMind), and a preview of a public verification tool. OpenAI said it has been attaching Content Credentials to images since 2024 (DALL·E 3, ImageGen, Sora) and is now a C2PA Conforming Generator Product so platforms can read and preserve provenance metadata. To make provenance more resilient when metadata is stripped or broken, OpenAI will embed SynthID invisible watermarks in images generated by ChatGPT, Codex, or the OpenAI API. The company is previewing a verification tool that checks uploaded images for Content Credentials and SynthID signals and will initially verify only OpenAI-originated content, with plans for broader cross-industry support over time.
OpenAI strengthens AI governance for Europe
OpenAI outlines measures to align its safety, security, transparency, and provenance practices with the EU AI Act and related Codes of Practice. The company highlights governance tools (system cards, Model Spec, Red Teaming Network), updated internal frameworks (Preparedness Framework updated 2025, Frontier Governance Framework), provenance efforts using C2PA and SynthID (expanding to audio and planning for text), and cybersecurity collaborations including a Trusted Access for Cyber program and an OpenAI EU Cyber Action Plan launched in early May 2026. OpenAI says it will continue updating resources and working with regulators, external experts, and partners as EU implementation proceeds.
Anthropic Adds Provenance Markers to Claude for EU AI Act
Anthropic has implemented machine-readable provenance marking in newer Claude models to meet the EU AI Act’s Article 50 transparency requirements that took effect on 2 August 2026. Supported Claude models published since that date embed invisible text watermarks and, for images and compatible files, attach digitally signed provenance metadata using the C2PA standard; digital signatures record that content was processed by Claude and indicate changes to stored metadata. Anthropic says the markings are applied globally, cloud-provider support for signed metadata varies, and it is working to retrofit older models and provide detection tools. The company cautions that watermarks only signal Claude processing and are not conclusive proof of authorship — they can sometimes survive copy‑paste or edits but have technical limits. Anthropic has joined the European Code of Practice on Transparency; the article also cites May 2026 funding, valuation, and revenue figures.
