Privacy-First AI: PII Masking and Encrypted Pipelines

Handling clinical conversations means assuming every byte is sensitive. ECHOSCRIPT runs automated PII detection and masking before data moves downstream, so identifiers never sit unprotected in logs, queues, or model context.

Encryption is end to end — in transit and at rest — and access is gated by role. Compliance isn't a checkbox at the end; it's a constraint that shapes the architecture from the first diagram.

The mindset shift is treating privacy as a feature with tests, not a policy document. If I can't prove data is masked and encrypted at each hop, the pipeline isn't done.
