AI Act – Article 50: transparency for chatbots and deepfakes by 2026

Excerpt — From 2 August 2026, any AI interaction with the public, any synthetic content (deepfakes, generated text/voice/visuals), and any “emotion recognition” or “biometric categorization” system must be explicitly disclosed. Non‑compliance can trigger fines up to €15M or 3% of global turnover.

The general rule

Article 50 of Regulation (EU) 2024/1689 (AI Act) imposes transparency obligations for certain “limited-risk” AI systems — notably:

• systems that interact with natural persons (chatbots, voice assistants);
• AI systems that generate or manipulate content (“deepfakes,” synthetic text/voice/images/videos);
• emotion recognition or biometric categorization systems.

The official text is published in the EU Official Journal; see the AI Act (Reg. 2024/1689) and its Article 50. Application: the transparency obligations (including Article 50) apply from 2 August 2026, per the timeline published by the Commission’s AI Act Service Desk. Sources:

• AI Act text on EUR‑Lex: Regulation (EU) 2024/1689 (includes Article 50). See the reference EUR‑Lex entry. (eur-lex.europa.eu)
• Article 50 factsheet on transparency obligations by the Commission’s Service Desk. (ai-act-service-desk.ec.europa.eu)
• Application timeline: transparency (Art. 50) applicable from 2 August 2026. (ai-act-service-desk.ec.europa.eu)

Penalties: failure to comply with Article 50 may be fined up to €15M or 3% of global annual turnover (whichever is higher), under Article 99 AI Act. (eur-lex.europa.eu)

Interaction with the GDPR: when personal data are processed, the transparency and information requirements of GDPR Articles 12 to 14 continue to apply (“concise, transparent, intelligible and easily accessible” form; information on ADM/profiling and its consequences where relevant). Official references: GDPR Articles 12 and 13 (EUR‑Lex/EDPB). (edpb.europa.eu, eur-lex.europa.eu)

What the regulator says

• European Commission (AI Act Service Desk) — scope of Article 50: disclosure is required for chatbots and AI‑generated/manipulated content (“deepfakes”), as well as for emotion recognition/biometric categorization systems. A narrow exemption exists for law‑enforcement uses, excluding tools made available to the public. (ai-act-service-desk.ec.europa.eu)
• European Commission (Digital Strategy) — ongoing work on practical labelling/display modalities for Article 50 (cross‑text consistency and user messaging). Useful to anticipate common implementation guidance. (digital-strategy.ec.europa.eu)
• CNPD (Luxembourg) — AI thematic files: reminder that some AI Act‑prohibited practices already raise GDPR concerns (incl. transparency) and may lead to CNPD complaints/investigations if deployed in Luxembourg. (cnpd.public.lu)

Key timeline points: the AI Act foresees phased application. Article 50 transparency obligations apply from 2 August 2026. In the meantime, organisations should prepare disclosures, labels, and processes. (ai-act-service-desk.ec.europa.eu)

How to implement in practice

Before deployment

1. Map Article 50‑triggering use cases
   • Chatbots/assistants (HR, customer support, online banking, internal helpdesks open to customers/public).
   • Content generation/retouching (marketing, comms, CSR, training): AI images/videos/voice/text, “avatars,” AI voice translations.
   • “Emotion recognition” (e.g., facial/voice analysis) or “biometric categorization” tools.

   Document for each: AI type, audience, channels (web, mobile, call centre, social), publication flow, and business owner. (ai-act-service-desk.ec.europa.eu)

2. Define the Article 50 + GDPR notice framework
   • Clear, unambiguous notice BEFORE or AT THE START of the interaction (chatbot/voicebot): “You are interacting with an AI system.” Place it where the user engages (button, window, voice prompt). (ai-act-service-desk.ec.europa.eu)
   • Labelling AI content (“deepfakes,” synthetic voices, generated texts/visuals): indicate that content is AI‑generated or AI‑manipulated; preserve this information on every re‑publication. (ai-act-service-desk.ec.europa.eu)
   • When personal data are processed, add the GDPR‑required information (controller, purposes, legal basis, rights, existence of ADM/profiling where relevant). (eur-lex.europa.eu)
3. Choose disclosure placements/formats
   • Web/app: first‑contact banner + persistent icon/label near the input field; for content, visible watermark or caption/slug; keep an “alt text”/metadata flagging synthetic nature.
   • Audio/voice: opening message (“This message was generated by AI”) + visual indicator in the player.
   • Video: opening and closing slate; subtitles mentioning “content generated by AI.”

   Exact formats will be discussed/aligned at EU level; follow Commission updates. (digital-strategy.ec.europa.eu)

During operations

4. Ensure permanence and accessibility
   • Information must remain “obvious and unavoidable” for the average user. Avoid buried mentions (menus, T&Cs). Repeat the notice if a conversation resumes after a significant delay. (ai-act-service-desk.ec.europa.eu)
   • Adapt to channel: visible mention on each carousel card, each video thumbnail, each published transcript.
5. Manage exemptions and sensitive cases
   • The AI Act’s law‑enforcement exemptions do not cover services made available to the public to report offences: those still require transparency. Obtain legal sign‑off before invoking any exemption. (ai-act-service-desk.ec.europa.eu)

After (control and evidence)

6. Traceability and audit
   • Keep proof of disclosures: screenshots/exports, versions of audio/visual scripts, publication timestamps, mapping of models and prompts.
   • Labelling and retention policy: retain originals and labelled versions; update if content is reused.
7. Incident and risk management
   • If AI content is published without proper labelling, correct, inform, and implement pre‑publication checks. Non‑compliance with Art. 50 exposes you to fines up to €15M or 3% of global turnover (Art. 99). (eur-lex.europa.eu)
8. Luxembourg/EU governance
   • In Luxembourg, the CNPD remains competent for GDPR (information, transparency, DPIA where high risk). For the AI Act, follow Commission (AI Office) communications and Service Desk updates on Article 50 practical modalities. (cnpd.public.lu)

Concrete examples (templates to adapt)

• Banking chatbot: “You are interacting with an AI‑powered conversational assistant. It may make mistakes. Do not share sensitive information. Learn more [GDPR notice link].”
• Corporate video with AI avatar: opening slate “This video contains an AI‑generated avatar and voice.” + persistent footer note “Content partially generated by AI.”
• Emotion detection in training: signage at room/platform entry: “Automated analysis of expressions/voice by AI (emotion recognition).” + GDPR notice detailing purposes and legal basis.

Common pitfalls

1. Hidden or one‑off notice
   • A disclosure buried in T&Cs or shown only on first visit is not enough. The reminder must be clear and recurring where the user acts. (ai-act-service-desk.ec.europa.eu)
2. Forgetting the distribution chain
   • Social reposts, partner sharing, email: the “AI” label must travel with the content (caption, watermark, metadata). Unlabelled reuses risk non‑compliance. (ai-act-service-desk.ec.europa.eu)
3. Confusing AI Act transparency with GDPR information
   • The “AI content” label does not replace GDPR information on data processing (GDPR Arts. 12–14). Both apply when personal data are involved. (edpb.europa.eu)
4. Overlooking “emotion recognition”/biometric categorization systems
   • Even for internal PoCs with volunteers, Art. 50 requires explicit notice; moreover, such processing may involve sensitive data (GDPR Art. 9) and/or require a DPIA. Legal review is essential. (eur-lex.europa.eu)
5. Assuming a generic “law‑enforcement exemption”
   • The exemption is strictly limited and does not apply to systems made available to the public to report offences. (ai-act-service-desk.ec.europa.eu)

Timeline note (as of 6 May 2026): Article 50 transparency obligations will apply from 2 August 2026. DPO/CISO/Comms teams should finalise by summer 2026 their display/labelling templates, associated GDPR notices, and audit evidence. (ai-act-service-desk.ec.europa.eu)
