How Maskflare masks Switzerland identifiers
Detections are replaced with a token such as mf_mask_d7e0 before the request goes to the AI provider, and with response restoration turned on the real value is put back in the answer. The other actions are redact, partial, hash, format-preserving encryption, generalize, alert and block.
- Protect now, Finance - Protect now, Healthcare and Developer: mask (a reversible token) when Switzerland is a primary country.
- Monitor first: alert (counted, forwarded unchanged) when Switzerland is a primary country.
Compliance profiles that include the Switzerland pack: Switzerland - nDSG health data.
Limits worth knowing
- A passing checksum shows that a value is well formed, not that it was issued to a real person. The examples on this page pass for that reason and are not real.
- 3 of the 15 detectors here match on pattern alone (eMediplan medication plan (QR payload), Passport / identity card number and Postal code), so they can match text that merely has the same shape.
- Detectors read the text of the request. A value inside an image is found only after OCR, and a value split across lines is not one match.
- Names, addresses and free-text details are handled by other packs. This page is limited to the Switzerland identifiers.
