Mongo ObjectId Key (ObjectIdPkGenerator)

The Mongo ObjectId Key generator generates values to de-identify fields that contain MongoDB ObjectId values. The column value must be 12 bytes long.

Link object structure

The ObjectId Key generator does not support linking. It can be self-consistent, but not consistent with another column. You cannot configure differential privacy.

The metadata object is populated from the ObjectIdPkMetadata object. preserveTimetampAndCounter indicates whether to only change the random value portion of the identifier, but keep the timestamp and incremented counter portions.

There is no generator-specific configuration.

{
  "schema": "string",
  "table": "string",
  "column": "string",
  "dataType": "string", //MongoDB only
  "metadata": {
    "presetId": "string",
    "generatorId": "ObjectIdPkGenerator",
    "isConsistent": false,
    "preserveTimestampAndCounter": false,
    "encryptionProcessor": "x-on", //To use configured Structural data encryption
    "customValueProcessor": "string"  //If custom value processor applied
  }
}

Example replacement

In the following example replacement for the Mongo ObjectId Key generator, consistency is disabled.

Only the random value portion of the identifier is changed.

{
  "name": "userid",
  "schema": "public",
  "table": "users",
  "links": [
    {
      "schema": "public",
      "table": "users",
      "column": "user_id",
      "dataType": "ObjectId",
      "metadata": {
        "presetId": "ObjectIdPkGenerator",
        "generatorId": "ObjectIdPkGenerator",
        "isConsistent": false,
        "preserveTimestampAndCounter": true
      }
    }
  ]
}
