HEALTHCARE AGENTS · PATIENT DE-IDENTIFICATION
THE METHOD
01
Classify, then segment
The agent classifies every field and span of free text, and segments Part 2 records before anything is transformed.
02
Measure the risk against numbers, not a checklist
The agent measures k-anonymity, l-diversity and t-closeness across the full linked record, each against a threshold the release must clear.
03
Change only what the numbers say to change
The agent suppresses or generalises only where a measurement misses, and shifts dates per patient so intervals survive.
04
The agent produces the evidence, then a person signs it
The agent drafts the determination. A qualified statistician signs it, and a checksum binds it to the exact data set.
WHAT IT PRODUCES
Built and run by the agent in your environment or ours, designed against the risk model.
Method, analysis and determination, drafted by the agent, signed by a qualified statistician, bound to the data set by checksum.
A shorter document for authorized recipients, so the full method log stays with you.
The determination holds for 24 months, with re-attestation when the data or population changes materially.
The agent keeps measuring between attestations, because a growing data set changes its risk profile.

FAQ
One of the two de-identification methods HIPAA allows, under 45 CFR 164.514(b)(1). A qualified statistician measures re-identification risk and determines in writing that it is very small.
No. There is no certification or register of approved attesters. The rule asks for appropriate statistical expertise and documented methods and results.
Yes, on its own track from the start. Part 2 records are segmented before any transformation and governed separately, because they carry obligations HIPAA alone does not.
