AI content authenticity and provenance
Watermark, disclose, and prove the origin of AI content.
The EU AI Act now requires AI-generated content to be marked and disclosed. Filigrane is the engineering-led guide to doing it properly, from the Webisoft team that builds watermarking, Content Credentials, and provenance systems into real products.
EU AI Act Article 50 transparency obligations apply in
Transparency obligations under Article 50 apply from 2 August 2026. Generative-AI systems already on the market get until 2 December 2026 to bring marking and detection into line. Penalties reach EUR 15M or 3% of global annual turnover.
Five things you now have to get right
Deep, cited, engineering-first guidance across the whole content-authenticity stack.
EU AI Act Article 50: every obligation, date, and penalty, explained
EU AI Act Article 50 requires watermarking and disclosure of AI content from 2 August 2026. Full obligations, timeline, and penalties, sourced and dated.
WatermarkingAI content watermarking: the engineering view
How AI content watermarking embeds detectable signals in text, images, audio, and video at generation time, and how to build or buy a pipeline.
Content CredentialsC2PA and Content Credentials, explained
What C2PA and Content Credentials are, how manifests, signing, and verification work, and who backs the standard, explained for product teams.
Deepfake provenanceDeepfake provenance: proving media is real instead of chasing fakes
Why cryptographically signed provenance beats deepfake detection as a long-term trust strategy, how C2PA signing works, and where its limits are.
Document provenanceDocument Provenance: How to Prove a Document Is Authentic and Unaltered
What document provenance means, how hashing, signatures, timestamps and audit trails prove authenticity, and when simpler tools are enough.
Why Filigrane
Most Article 50 content online stops at "you must comply." We are the engineers who actually wire watermarking, C2PA Content Credentials signing, and provenance verification into a product. Every page here is written from that build experience, cited to primary sources, and kept current.
Standards-neutral
We compare SynthID, C2PA, and open watermarking honestly, and tell you where each fits.
Implementation-first
Not policy memos. The actual pipeline: embed at generation, disclose in the UI, verify after the fact.
Built by Webisoft
A software engineering firm. We scope and build the system, then hand you something that ships.
