Deidentificator

Remove identifying data, replace IDs with transport IDs, and handle date shifting via the DateShift-ID Pattern.

The CDA:

1. Deidentifies the bundle in a single pass, generating transport IDs (tIDs) on-the-fly for each unique ID and date value, attaching tID extensions and nulling date values during deidentification
2. Sends the generated mappings — ID pairs (originalID, tID) and date pairs (tID, originalDate) — to the TCA for secure storage
3. Receives transferId from TCA and forwards it with the deidentified bundle to the RDA

For more details, see the De-Identification documentation.

Bundle Sender

Send patient bundle to RDA.
