Lawful basis and consent for personal data used in AI

Medium effortCovered by ISO 27001: StrongSatisfies 8 obligations in 7 policies

What it means

  • Before using personal data to train, test or run an AI system, confirm you have a valid basis under the DPDP Act 2023 (consent, or a listed legitimate use) for that specific purpose.
  • If data was collected for one purpose (servicing a loan) and you now want to use it for another (training a marketing model), check whether the original notice and consent cover it.
  • Notices tell people in plain language that AI is used and what data it uses; consent can be withdrawn, and withdrawal is honoured.
  • Covers personal data sent to external AI providers too.

Why it matters

  • RBI FREE-AI expects AI data use aligned with the DPDP Act.
  • Using data beyond its stated purpose is one of the easiest DPDP breaches to prove.
  • ICMR and NITI Aayog guidance both stress consent and user control.

Checklist

  1. For each AI system using personal data, record the purpose, data categories, and lawful basis in the record of processing.
  2. Check privacy notices mention AI use and the relevant purposes; update notices and consent flows where they do not.
  3. Assess whether new AI purposes are compatible with the original collection; seek fresh consent where needed.
  4. Build a way to honour consent withdrawal for AI uses (exclude from future training and inference).
  5. Ensure DPAs with AI vendors restrict use of personal data to your instructions.
  6. Have the DPO or privacy lead sign off before go-live.

Evidence examples

  • Record of processing entry for the AI underwriting model with lawful basis.
  • Updated privacy notice (version and date) mentioning AI-assisted decisions.
  • Consent manager logs or consent records for AI-specific purposes.
  • DPO sign-off on the AI system's privacy review.
  • Vendor DPA clause restricting training on customer personal data.

Common pitfalls

  • Assuming "we already have the data" means "we can use it for AI".
  • Privacy notice silent on AI and automated decisions.
  • Withdrawal honoured in the CRM but not in model training pipelines.
  • Pasting customer data into public GenAI tools.

Key takeaways

  • Every AI use of personal data needs a purpose and a valid basis under the DPDP Act.
  • Partial reuse from ISO 27001 (A.5.31, A.5.34); much stronger reuse if you already run a DPDP privacy programme or SOC 2 Privacy criteria.
  • Make sure consent withdrawal reaches training pipelines.
