In Korea, every time a government body releases a slice of your health records through the national health-data channel, that release is logged — stamped with which agency handed the data over, which part of your record it was, and the exact second it happened. In one recent month, a routine user's log held 45 such access events. You can check who accessed your medical records yourself in a few minutes, using one government portal and one app, and here is the path.
Where your data is
Your health data does not sit still inside one hospital. Through the 건강정보 고속도로 (Health Information Highway), records from 860 institutions — tertiary hospitals, general hospitals, and local clinics — are exchanged in a national standard covering 12 categories and 113 data items: checkups, medications, vaccinations, diagnostic tests, and surgical history.
A single visit to a clinic or a pharmacy can set several of these data pulls in motion. They happen in the background, on your behalf, and you are usually the last to know any of it occurred.
Ministry of Health and Welfare: the platform links 860 medical institutions and lets individuals retrieve, store, and transmit their own health data with their consent.
This free service keeps track of every access
The "Highway" is run from a single government portal: 마이헬스웨이 (myhealthway.go.kr), the Ministry of Health and Welfare's platform for the exchange. It is the citizen-facing side of the whole system — where you sign in as yourself, see what the institutions hold on you, and ask for it to be sent somewhere.
마이헬스웨이 is a relay. Your records stay with the institution that holds them, and the portal passes a copy along to wherever you have chosen to send it.
What the portal keeps is the ledger. Every time your data is viewed, saved, shared, or downloaded through the channel, it records the event (조회·저장·공유 이력). Each entry names the provider that released the data — 건강보험공단, 심사평가원, or 질병관리청 — the category of record, who or what requested it, and the timestamp.
Services you can access
These are some of the services available in myhealthway.go.kr.
- 진료기록 열람내역 조회 — who accessed your records. Each read of your health data through the channel, with the releasing provider and the timestamp.
- 활용서비스 공유 이력 — what was shared. Records passed to a third-party service you connected to your account.
- 활용서비스 다운로드 이력 — what was downloaded. Records saved out of the platform to a device or an outside service.
- 전송요구내역 조회 — your transmission requests. The record of every time you asked the platform to send your data somewhere.
Check it yourself
Open the 나의건강기록 app — the actively developed flagship client, redesigned on 7 July 2026 with family-record viewing and travel-quarantine features — or open myhealthway.go.kr in a browser.
Sign in with 본인인증. Expect an identity check: a 공동/금융인증서, or a 휴대폰 간편인증. There is no anonymous view of a medical log.
Then open your health record and find 열람내역 / 이력.
The app is still under heavy development and has known issues on iPhone. When it acts up, the browser portal at myhealthway.go.kr is the reliable fallback, and it exposes the same logs.
Your right to data portability
You have a growing set of rights over this data. The 전송요구권 (data portability) under Article 35-2 of the Personal Information Protection Act took effect for medical data on 13 March 2025 — it lets you require your records be sent where you choose. The access log itself is the platform's own transparency layer: 마이헬스웨이 runs under the 의료법 (Medical Service Act, Art. 21-2), and the log is how you see who has actually been reading your records.
When did you last check who has been looking at your own health records — and would you recognise every name in the list if you did?
