Character Substitution (StringMaskGenerator)

The Character Substitution generator performs a random character replacement that preserves formatting (spaces, capitalization, and punctuation).

Characters are replaced with other characters from within the same Unicode Block.

Link object structure

The Character Substitution generator is implicitly consistent. You cannot configure consistency or differential privacy. There is no generator-specific configuration.

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

Example replacement

The following example replacement assigns the Character Substitution generator to a column.

{
  "name": "age",
  "schema": "public",
  "table": "users",
  "links": [
    {
      "schema": "public",
      "table": "users",
      "column": "age",
      "metadata": {
        "generatorId": "StringMaskGenerator"
      }
    }
  ]
}
