# Sensitive data safe handling

Use this before card, personal, or health data moves: redact PCI card
data, handle PII and PHI (protected health information) by the regime,
and contain spills fast.

You need the draft, transcript, or record to check, the regimes and
redaction tool from prefs, and the vault or safe-store path.

## Name what is in the text

Call out card numbers and CVVs, government IDs, passwords and tokens,
health details, and any other identifiers. Give each finding its data type
and line number with a redacted fragment only — never reproduce the raw
value, not in the finding, the log, or anything you hand back, because the
masking step comes later and a quoted PAN, CVV, token or health detail has
already escaped by then. A scan you cannot run is UNKNOWN, never "clean".

## Redact before anything moves

Mask card data to last four, strip CVVs and full credentials entirely,
and minimize PII to what the case needs. Fix what a reword can fix and
mark each change; route what it cannot — data already exposed, a
required record that must keep identifiers — to the compliance owner
with a short packet.

## Stop capture before live card data

On payment calls, pause recording or mask keypad (DTMF) entry before
collection, and resume after authorization. Never store sensitive
authentication data — CVV, PIN, or magnetic-stripe track data — in audio,
screen recordings, or transcripts; the recording itself becomes the
violation. Redact any such slip from transcripts immediately.

## Check the PHI handling path too

Confirm minimum-necessary access (except treatment, disclosures to the
individual, authorized uses, disclosures to the regulator, or as
required by law), identity verified before any PHI talk, encrypted
store, no health detail in ticket subjects or public replies, and
and retention on the applicable PHI schedule — keep the record only as long
as it is genuinely needed, and scope the six-year default to the compliance
documentation that actually requires it rather than to every case record. A PHI finding outside the safe path is P1
until contained.

Stamp the result: clean, redacted, or blocked-with-owner. Blocked items
never move before the compliance yes. Log regimes, verdict, and
approver on the case.

After a spill, draft the containment note: what leaked, where, who saw
it, the purge or rotate steps, and the prevention fix. Offer to
re-check the macro or template source so the next use starts clean.

Deliver the findings list, the redacted text or the owner packet, the
verdict stamp, and the case log line.

## What not to do

No redaction tool means manual masking with a second pair of eyes
required, and the tool gap named. Never declare text clean by
skimming.
