Creating Cloud DLP de-identification templates

You can use templates to create and persist configuration information to use with Cloud Data Loss Prevention (DLP). Templates are useful for decoupling configuration such as what you inspect for and how you de-identify it from the implementation of your requests. Templates provide a robust way to re-use configuration and enable consistency across users and data sets.

The Cloud DLP supports two types of templates:

• De-identification templates: Templates for saving configuration information for de-identification jobs, including both infoType and record (structured dataset) transformations.
• Inspection templates: Templates for persisting configuration information for inspection scan jobs, including what predefined or custom detectors to use. For more information about inspection templates, see Creating Cloud DLP inspection templates.

For conceptual information about templates in Cloud DLP, see Templates.

The remainder of this topic shows you how to create de-identification templates for use with the Cloud DLP.

Create a de-identification template

It’s useful to note that a de-identification template is simply a reusable de-identification configuration plus some metadata. In API terms, the DeidentifyTemplate object is effectively a DeidentifyConfig object that includes a few more fields of metadata, such as a display name and a description. Therefore, to create a new de-identification template, the basic steps are:

1. Start with a DeidentifyConfig object.
2. Call or POST the create method of the projects.deidentifyTemplates resource, including in your request a DeidentifyTemplate object that contains a display name, a description, and that DeidentifyConfig object.

The returned DeidentifyTemplate will be usable immediately. You can reference it in other calls or jobs by its name. You can list the existing templates by calling the *.deidentifyTemplates.list method. To view a specific template, call the *.deidentifyTemplates.get method. Note that the limit for the number of templates you can create is 1000.

If you've already had some experience de-identifying sensitive data from text, images, or structured content using Cloud DLP, you've already created a DeidentifyConfig object. One additional step turns it into a DeidentifyTemplate object.

REST example

The following JSON is an example of what you could send to the projects.deidentifyTemplates.create method. This JSON creates a new template with the given display name and description, and scans for matches on the infoTypes EMAIL_ADDRESS and GENERIC_ID. When it finds content matching those infoTypes, it will mask the first three characters with an asterisk (*) character:

JSON Input:

POST https://dlp.googleapis.com/v2/projects/[PROJECT_ID]/deidentifyTemplates?key={YOUR_API_KEY}

{
  "deidentifyTemplate":{
    "displayName":"Email and id masker",
    "description":"De-identifies emails and ids with a series of asterisks.",
    "deidentifyConfig":{
      "infoTypeTransformations":{
        "transformations":[
          {
            "infoTypes":[
              {
                "name":"GENERIC_ID"
              }
            ],
            "primitiveTransformation":{
              "replaceWithInfoTypeConfig":{

              }
            }
          },
          {
            "infoTypes":[
              {
                "name":"EMAIL_ADDRESS"
              }
            ],
            "primitiveTransformation":{
              "characterMaskConfig":{
                "charactersToIgnore":[
                  {
                    "charactersToSkip":"@"
                  }
                ],
                "maskingCharacter":"*"
              }
            }
          }
        ]
      }
    }
  }
}

JSON Output:

{
  "name":"projects/[PROJECT_ID]/deidentifyTemplates/[JOB-ID]",
  "displayName":"Email and id masker",
  "description":"De-identifies emails and ids with a series of asterisks.",
  "createTime":"2018-11-30T07:17:59.536022Z",
  "updateTime":"2018-11-30T07:17:59.536022Z",
  "deidentifyConfig":{
    "infoTypeTransformations":{
      "transformations":[
        {
          "infoTypes":[
            {
              "name":"GENERIC_ID"
            }
          ],
          "primitiveTransformation":{
            "replaceWithInfoTypeConfig":{

            }
          }
        },
        {
          "infoTypes":[
            {
              "name":"EMAIL_ADDRESS"
            }
          ],
          "primitiveTransformation":{
            "characterMaskConfig":{
              "maskingCharacter":"*",
              "charactersToIgnore":[
                {
                  "charactersToSkip":"@"
                }
              ]
            }
          }
        }
      ]
    }
  }
}

To quickly try this out, you can use the APIs Explorer that's embedded below. For general information about using JSON to send requests to the Cloud DLP API, see the JSON quickstart.

Using de-identification templates

Once you’ve created a new template, you can use its name identifier anywhere deidentifyTemplateName is accepted, such as:

• projects.content.deidentify: De-identifies potentially sensitive data in content using the template as its configuration. Be aware that this method can use either an inspection template or a de-identification template.

Listing de-identification templates

To list all de-identification templates that have been created, use one of the *.*.list methods:

• projects.deidentifyTemplates.list

Code examples

Following is sample code in several languages that demonstrates how to use Cloud DLP to list inspection templates. The process is identical to the one for listing de-identification templates.

Important: The code on this page requires that you first set up a Cloud DLP client. For more information about installing and creating a Cloud DLP client, see Cloud DLP client libraries. (Sending JSON to Cloud DLP REST endpoints does not require a client library.)

To delete a specific de-identification template, use one of the *.*.delete methods:

• projects.deidentifyTemplates.delete

With each *.*.delete method, you include the resource name of the template to be deleted.
