Detect 13–19 digit card numbers spoken or typed, including numbers split across turns or separated by spaces, dashes or the words 'space' and 'dash'. Validate with the Luhn check before acting. Keep only the last four digits so agents can confirm the card. Mute the matching audio segment in the recording.

Detect national identity numbers (US SSN 3-2-4, Aadhaar 12 digits, NI numbers) whether spoken digit by digit or typed. Replace with a stable one-way hash so the same person can still be matched across conversations without storing the number itself. Never place the raw value in summaries or exports.

Detect any credential the customer or agent reveals: passwords, PINs, one-time codes, security answers, bearer tokens and API keys. Block means the value is never written to storage at all — drop it at ingestion and log only that a credential was spoken. Prompt the agent to stop the customer from reading credentials aloud.

Detect account numbers, sort codes, routing numbers, IBAN and UPI handles. Keep the last four characters for verification and mask the rest. Allow the masked value into the case record so refunds can be traced.

Redact diagnoses, medications, treatment details and insurance member IDs. Keep the fact that a health topic was discussed so categorisation still works, but remove the specific condition.

Redact phone numbers, personal email addresses and home addresses before knowledge indexing or export. Leave them visible inside the live conversation so the agent can complete the task.
