Death-certificate de-identification is the removal of the decedent, informant, and certifier IDs. It meets HIPAA Safe Harbor (45 CFR §164.514(b)). anonym.plus runs locally and keeps the cause-of-death chain and broad demographics for mortality work.
When this applies
Mortality datasets drive public-health research. But the file carries the full identity, the informant (often a relative), and the signing doctor. All must go before you share it.
How anonym.plus handles it
- Load the file into anonym.plus on your device.
- It finds decedent, informant, and certifier IDs.
- Exact dates and places get flagged; the cause text stays.
- Swap or black out the confirmed IDs.
- Save the clean file on your device.
What you need to provide
- The certificate (PDF, scan, or registry export).
- A date and place broaden option for Safe Harbor.
- An operator to suit the later use.

Limitations & cautions
HIPAA guards a decedent's PHI for 50 years. Place and exact date are strong clues in mortality data — make them broad. A rare cause plus a place can re-identify after direct IDs go.
Frequently asked questions
Is a dead person's data still HIPAA-protected?
Yes. The Privacy Rule guards a decedent's PHI for 50 years after death, so these files still need de-identification before reuse.
Are informant and certifier details removed too?
Yes. The informant (often a relative) and the signing doctor are IDs and are flagged together.
Can the cause chain stay?
Yes. The cause chain stays for analysis. Only IDs go, though a rare cause needs extra care.
