dataPolicyType

enum (DataPolicyType)

Required. Data policy type. Type of data policy.
dataPolicyId

string

User-assigned (human readable) ID of the data policy that needs to be unique within a project. Used as {dataPolicyId} in part of the resource name.
Union field matching_label. Label that is bound to this data policy. matching_label can be only one of the following:
policyTag

string

Policy tag resource name, in the format of projects/{projectNumber}/locations/{locationId}/taxonomies/{taxonomyId}/policyTags/{policyTag_id}.
Union field policy. The policy that is bound to this data policy. policy can be only one of the following:
dataMaskingPolicy

object (DataMaskingPolicy)

The data masking policy that specifies the data masking rule to use.

DataMaskingPolicy

The data masking policy that is used to specify data masking rule.

JSON representation 
{    // Union field masking_expression can be only one of the following:   "predefinedExpression": enum (PredefinedExpression),   "routine": string   // End of list of possible types for union field masking_expression. }
Fields
Union field masking_expression. A masking expression to bind to the data masking rule. masking_expression can be only one of the following:
predefinedExpression

enum (PredefinedExpression)

A predefined masking expression.
routine

string

The name of the BigQuery routine that contains the custom masking routine, in the format of projects/{projectNumber}/datasets/{dataset_id}/routines/{routine_id}.

PredefinedExpression

The available masking rules. Learn more here: https://cloud.google.com/bigquery/docs/column-data-masking-intro#masking_options.

Enums
PREDEFINED_EXPRESSION_UNSPECIFIED Default, unspecified predefined expression. No masking will take place since no expression is specified.
SHA256 Masking expression to replace data with SHA-256 hash.
ALWAYS_NULL Masking expression to replace data with NULLs.
DEFAULT_MASKING_VALUE

Masking expression to replace data with their default masking values. The default masking values for each type listed as below:

  • STRING: ""
  • BYTES: b''
  • INTEGER: 0
  • FLOAT: 0.0
  • NUMERIC: 0
  • BOOLEAN: FALSE
  • TIMESTAMP: 1970-01-01 00:00:00 UTC
  • DATE: 1970-01-01
  • TIME: 00:00:00
  • DATETIME: 1970-01-01T00:00:00
  • GEOGRAPHY: POINT(0 0)
  • BIGNUMERIC: 0
  • ARRAY: []
  • STRUCT: NOT_APPLICABLE
  • JSON: NULL
LAST_FOUR_CHARACTERS

Masking expression shows the last four characters of text. The masking behavior is as follows:

  • If text length > 4 characters: Replace text with XXXXX, append last four characters of original text.
  • If text length <= 4 characters: Apply SHA-256 hash.
FIRST_FOUR_CHARACTERS

Masking expression shows the first four characters of text. The masking behavior is as follows:

  • If text length > 4 characters: Replace text with XXXXX, prepend first four characters of original text.
  • If text length <= 4 characters: Apply SHA-256 hash.
EMAIL_MASK

Masking expression for email addresses. The masking behavior is as follows:

For more information, see Email mask.
DATE_YEAR_MASK

Masking expression to only show the year of Date, DateTime and TimeStamp. For example, with the year 2076:

  • DATE : 2076-01-01
  • DATETIME : 2076-01-01T00:00:00
  • TIMESTAMP : 2076-01-01 00:00:00 UTC

Truncation occurs according to the UTC time zone. To change this, adjust the default time zone using the time_zone system variable. For more information, see the System variables reference.
