available when using reservations that are created with certain BigQuery editions. For more information about which features are enabled in each edition, see <a href="/bigquery/docs/editions-intro">Introduction to BigQuery editions</a>.</span></aside> <p>BigQuery supports <a href="/bigquery/docs/column-data-masking">data masking</a> at the column level. You can use data masking to selectively obscure column data for users groups, while still allowing them access to the column. Data masking functionality is built on top of <a href="/bigquery/docs/column-level-security-intro">column-level access control</a>, so you should familiarize yourself with that feature before you proceed.</p> <p>When you use data masking in combination with column-level access control, you can configure a range of access to column data, from full access to no access, based on the needs of different user groups. For example, for tax ID data, you might want to grant your accounting group full access, your analyst group masked access, and your sales group no access.</p> <h2 id="benefits" data-text="Benefits" tabindex="-1">Benefits</h2> <p>Data masking provides the following benefits:</p> <ul> <li>It streamlines the data sharing process. You can mask sensitive columns to make it possible to share tables with larger groups.</li> <li>Unlike with column-level access control, you don't need to modify existing queries by excluding the columns that the user cannot access. When you configure data masking, existing queries automatically mask column data based on the roles the user has been granted.</li> <li>You can apply data access policies at scale. You can write a data policy, associate it with a policy tag, and apply the policy tag to any number of columns.</li> <li>It enables attribute-based access control. A policy tag attached to a column provides contextual data access, which is determined by the data policy and the principals that are associated with that policy tag.</li> </ul> <h2 id="data_masking_workflow" data-text="Data masking workflow" tabindex="-1">Data masking workflow</h2> <p>Figure 1 shows the workflow for configuring data masking:</p> <p><img src="/static/bigquery/images/data-masking-workflow.png" alt="To enable data masking, you must create a taxonomy, create data policies for the policy tags in the taxonomy, and then associate the policy tags with table columns." width="850" class="image"> <strong>Figure 1.</strong> Data masking components.</p> <p>You configure data masking with the following steps:</p> <ol> <li><a href="/bigquery/docs/column-level-security#create_taxonomy">Set up a taxonomy and one or more policy tags</a>.</li> <li><p>Configure <em>data policies</em> for the policy tags. A data policy maps a <a href="#masking_options"><em>data masking rule</em></a> and one or more principals, which represent users or groups, to the policy tag.</p> <p>When <a href="/bigquery/docs/column-data-masking#create_data_policies">creating a data policy</a> by using the Google Cloud console, you create the data masking rule and specify the principals in one step. When creating a data policy by using the BigQuery Data Policy API, you create the data policy and data masking rule in one step, and specify the principals for the data policy in a second step.</p></li> <li><p>Assign the policy tags to columns in BigQuery tables to apply the data policies.</p></li> <li><p>Assign users who should have access to masked data to the BigQuery Masked Reader role. As a best practice, assign the BigQuery Masked Reader role at the data policy level. Assigning the role at the project level or higher grants users permissions to all data policies under the project, which can lead to issues caused by excess permissions.</p> <p>The policy tag that is associated with a data policy can also be used for column-level access control. In that case, the policy tag is also associated with one or more principals who are granted the Data Catalog Fine-Grained Reader role. This enables these principals to access the original, unmasked column data.</p></li> </ol> <p>Figure 2 shows how column-level access control and data masking work together:</p> <p><img src="/static/bigquery/images/data-masking-components.png" alt="Policy tags are associated with data policies to configure data masking, and then associated with table columns to enable masking." width="850" class="image"> <strong>Figure 2.</strong> Data masking components.</p> <p>For more information about role interaction, see <a href="/bigquery/docs/column-data-masking-intro#role-interaction">How Masked Reader and Fine-Grained Reader roles interact</a>. For more information about policy tag inheritance, see <a href="/bigquery/docs/column-data-masking-intro#auth-inheritance">Roles and policy tag hierarchy</a>.</p> <h2 id="masking_options" data-text="Data masking rules" tabindex="-1">Data masking rules</h2> <p>When you use data masking, a data masking rule is applied to a column at query runtime, based on the role of the user running the query. Masking takes precedence to any other operations involved in the query. The data masking rule determines the type of data masking applied to the column data.</p> <p id="custom_mask">You can use the following data masking rules: </p> <ul> <li><p><strong>Custom masking routine</strong>. Returns the column's value after applying a <a href="/bigquery/docs/user-defined-functions#custom-mask">user-defined function (UDF)</a> to the column. <a href="/bigquery/docs/routines#permissions">Routine permissions</a> are required to manage the masking rule. This rule, by design, supports all <a href="/bigquery/docs/reference/standard-sql/data-types">BigQuery data types</a> except for the <code translate="no" dir="ltr">STRUCT</code> data type. However, support for data types other than <code translate="no" dir="ltr">STRING</code> and <code translate="no" dir="ltr">BYTES</code> is limited. The output depends on the defined function.</p> <p>For more information about creating UDFs for custom masking routines, see <a href="/bigquery/docs/user-defined-functions#custom-mask">Create custom masking routines</a>.</p></li> <li><p><strong>Date year mask</strong>. Returns the column's value after truncating the value to its year, setting all non-year parts of the value to the beginning of the year. You can only use this rule with columns that use the <code translate="no" dir="ltr">DATE</code>, <code translate="no" dir="ltr">DATETIME</code>, and <code translate="no" dir="ltr">TIMESTAMP</code> data types. For example:</p> <table> <thead> <tr> <th>Type</th> <th>Original</th> <th>Masked</th> </tr> </thead> <tbody> <tr> <td><code translate="no" dir="ltr">DATE</code></td> <td>2030-07-17</td> <td>2030-01-01</td> </tr> <tr> <td><code translate="no" dir="ltr">DATETIME</code></td> <td>2030-07-17T01:45:06</td> <td>2030-01-01T00:00:00</td> </tr> <tr> <td><code translate="no" dir="ltr">TIMESTAMP</code></td> <td>2030-07-17 01:45:06</td> <td>2030-01-01 00:00:00</td> </tr> </tbody> </table> <aside class="note"><strong>Note:</strong><span> Truncation occurs according to the UTC time zone. To change this, adjust the default time zone using the <strong>@@time_zone</strong> <a href="/bigquery/docs/reference/system-variables">system variable</a>.</span></aside></li> <li><p><strong>Default masking value</strong>. Returns a default masking value for the column based on the column's data type. Use this when you want to hide the value of the column but reveal the data type. When this data masking rule is applied to a column, it makes it less useful in query <a href="/bigquery/docs/reference/standard-sql/query-syntax#join_types"><code translate="no" dir="ltr">JOIN</code></a> operations for users with Masked Reader access. This is because a default value isn't sufficiently unique to be useful when joining tables.</p> <p>The following table shows the default masking value for each data type:</p> <table> <thead> <tr> <th><strong>Data type</strong></th> <th><strong>Default masking value</strong></th> </tr> </thead> <tbody> <tr> <td><code translate="no" dir="ltr">STRING</code></td> <td>""</td> </tr> <tr> <td><code translate="no" dir="ltr">BYTES</code></td> <td>b''</td> </tr> <tr> <td><code translate="no" dir="ltr">INTEGER</code></td> <td>0</td> </tr> <tr> <td><code translate="no" dir="ltr">FLOAT</code></td> <td>0.0</td> </tr> <tr> <td><code translate="no" dir="ltr">NUMERIC</code></td> <td>0</td> </tr> <tr> <td><code translate="no" dir="ltr">BOOLEAN</code></td> <td><code translate="no" dir="ltr">FALSE</code></td> </tr> <tr> <td><code translate="no" dir="ltr">TIMESTAMP</code></td> <td>1970-01-01 00:00:00 UTC</td> </tr> <tr> <td><code translate="no" dir="ltr">DATE</code></td> <td>1970-01-01</td> </tr> <tr> <td><code translate="no" dir="ltr">TIME</code></td> <td>00:00:00</td> </tr> <tr> <td><code translate="no" dir="ltr">DATETIME</code></td> <td>1970-01-01T00:00:00</td> </tr> <tr> <td><code translate="no" dir="ltr">GEOGRAPHY</code></td> <td>POINT(0 0)</td> </tr> <tr> <td><code translate="no" dir="ltr">BIGNUMERIC</code></td> <td>0</td> </tr> <tr> <td><code translate="no" dir="ltr">ARRAY</code></td> <td>[]</td> </tr> <tr> <td><code translate="no" dir="ltr">STRUCT</code></td> <td><p>NOT_APPLICABLE</p> <p> Policy tags can't be applied to columns that use the <code translate="no" dir="ltr">STRUCT</code> data type, but they can be associated with the leaf fields of such columns. </p> </td> </tr> <tr> <td><code translate="no" dir="ltr">JSON</code></td> <td>null</td> </tr> </tbody> </table></li> <li><p><strong>Email mask</strong>. Returns the column's value after replacing the username of a valid email with <code translate="no" dir="ltr">XXXXX</code>. If the column's value is not a valid email address, then it returns the column's value after it has been run through the <a href="/bigquery/docs/reference/standard-sql/hash_functions#sha256">SHA-256</a> hash function. You can only use this rule with columns that use the <code translate="no" dir="ltr">STRING</code> data type. For example:</p> <table> <thead> <tr> <th>Original</th> <th>Masked</th> </tr> </thead> <tbody> <tr> <td><code translate="no" dir="ltr">abc123@gmail.com</code></td> <td><code translate="no" dir="ltr">XXXXX@gmail.com</code></td> </tr> <tr> <td><code translate="no" dir="ltr">randomtext</code></td> <td><code translate="no" dir="ltr">jQHDyQuj7vJcveEe59ygb3Zcvj0B5FJINBzgM6Bypgw=</code></td> </tr> <tr> <td><code translate="no" dir="ltr">test@gmail@gmail.com</code></td> <td><code translate="no" dir="ltr">Qdje6MO+GLwI0u+KyRyAICDjHbLF1ImxRqaW08tY52k=</code></td> </tr> </tbody> </table></li> <li><p><strong>First four characters</strong>. Returns the first 4 characters of the column's value, replacing the rest of the string with <code translate="no" dir="ltr">XXXXX</code>. If the column's value is equal to or less than 4 characters in length, then it returns the column's value after it has been run through the <a href="/bigquery/docs/reference/standard-sql/hash_functions#sha256">SHA-256</a> hash function. You can only use this rule with columns that use the <code translate="no" dir="ltr">STRING</code> data type.</p></li> <li><p><strong>Hash (SHA-256)</strong>. Returns the column's value after it has been run through the <a href="/bigquery/docs/reference/standard-sql/hash_functions#sha256">SHA-256</a> hash function. Use this when you want the end user to be able to use this column in a <a href="/bigquery/docs/reference/standard-sql/query-syntax#join_types"><code translate="no" dir="ltr">JOIN</code> operation</a> for a query. You can only use this rule with columns that use the <code translate="no" dir="ltr">STRING</code> or <code translate="no" dir="ltr">BYTES</code> data types.</p> <p>The SHA-256 function used in data masking is type preserving, so the hash value it returns has the same data type as the column value. For example, the hash value for a <code translate="no" dir="ltr">STRING</code> column value also has a <code translate="no" dir="ltr">STRING</code> data type.</p> <aside class="special"><strong>Important:</strong><span> SHA-256 is a deterministic hashing function; an initial value always resolves to the same hash value. However, it does not require encryption keys. This makes it possible for a malicious actor to use a brute force attack to determine the original value, by running all possible original values through the SHA-256 algorithm and seeing which one produces a hash that matches the hash returned by data masking.</span></aside></li> <li><p><strong>Last four characters</strong>. Returns the last 4 characters of the column's value, replacing the rest of the string with <code translate="no" dir="ltr">XXXXX</code>. If the column's value is equal to or less than 4 characters in length, then it returns the column's value after it has been run through the <a href="/bigquery/docs/reference/standard-sql/hash_functions#sha256">SHA-256</a> hash function. You can only use this rule with columns that use the <code translate="no" dir="ltr">STRING</code> data type.</p></li> <li><p><strong>Nullify</strong>. Returns <code translate="no" dir="ltr">NULL</code> instead of the column value. Use this when you want to hide both the value and the data type of the column. When this data masking rule is applied to a column, it makes it less useful in query <a href="/bigquery/docs/reference/standard-sql/query-syntax#join_types"><code translate="no" dir="ltr">JOIN</code></a> operations for users with Masked Reader access. This is because a <code translate="no" dir="ltr">NULL</code> value isn't sufficiently unique to be useful when joining tables.</p></li> </ul> <h3 id="data_masking_rule_hierarchy" data-text="Data masking rule hierarchy" tabindex="-1">Data masking rule hierarchy</h3> <p>You can configure up to nine data policies for a policy tag, each with a different data masking rule associated with it. One of these policies is reserved for <a href="/bigquery/docs/column-level-security#set_up_column-level_access_control">column-level access control settings</a>. This makes it possible for several data policies to be applied to a column in a user's query, based on the groups that the user is a member of. When this happens, BigQuery chooses which data masking rule to apply based on the following hierarchy:</p> <ol> <li>Custom masking routine</li> <li>Hash (SHA-256)</li> <li>Email mask</li> <li>Last four characters</li> <li>First four characters</li> <li>Date year mask</li> <li>Default masking value</li> <li>Nullify</li> </ol> <p>For example, user A is a member of both the employees and the accounting groups. User A runs a query that includes the <code translate="no" dir="ltr">sales_total</code> field, which has the <code translate="no" dir="ltr">confidential</code> policy tag applied.

For a given column, it is possible to have some users with the BigQuery Masked Reader role that allows them to read masked data, some users with the Data Catalog Fine-Grained Reader role that allows them to read unmasked data, some users with both, and some users with neither. These roles interact as follows:</p> <ul> <li>User with both Fine-Grained Reader and Masked Reader roles: what the user sees depends on where in the policy tag hierarchy each role is granted. For more information, see <a href="#auth-inheritance">Authorization inheritance in a policy tag hierarchy</a>.</li> <li>User with Fine-Grained Reader role: can see unmasked (unobscured) column data.</li> <li>User with Masked Reader role: can see masked (obscured) column data.</li> <li>User with neither role: permission denied.</li> </ul> <p>In the case where a table has columns that are secured or secured and masked, in order to run a <code translate="no" dir="ltr">SELECT * FROM</code> statement on that table, a user must be a member of appropriate groups such that they are granted Masked Reader or Fine-Grained Reader roles on all of these columns.</p> <p>A user who is not granted these roles must instead specify only columns that they have access to in the <code translate="no" dir="ltr">SELECT</code> statement, or use <code translate="no" dir="ltr">SELECT * EXCEPT (<var translate="no">restricted_columns</var>) FROM</code> to exclude the secured or masked columns.</p> <h3 id="auth-inheritance" data-text="Authorization inheritance in a policy tag hierarchy" tabindex="-1">Authorization inheritance in a policy tag hierarchy</h3> <p>Roles are evaluated starting at the policy tag associated with a column, and then checked at each ascending level of the taxonomy, until the user either is determined to have appropriate permissions or the top of the policy tag hierarchy is reached.</p> <p>For example, take the policy tag and data policy configuration shown in Figure 4:</p> <p><img src="/static/bigquery/images/data-masking-inheritance.png" alt="Evaluating user access when Masked Reader is granted at a higher level of the taxonomy and Fine-Grained Reader is granted at a lower level of the taxonomy." width="600" class="image"> </p> <p><strong>Figure 4.</strong> Policy tag and data policy configuration.</p> <p>You have a table column that is annotated with the <code translate="no" dir="ltr">Financial</code> policy tag, and a user who is a member of both the ftes@example.com and analysts@example.com groups. When this user runs a query that includes the annotated column, their access is determined by the hierarchy defined in the policy tag taxonomy. Because the user is granted the Data Catalog Fine-Grained Reader role by the <code translate="no" dir="ltr">Financial</code> policy tag, the query returns unmasked column data.</p> <p>If another user who is only a member of the ftes@example.com role runs a query that includes the annotated column, the query returns column data that has been hashed using the SHA-256 algorithm, because the user is granted the BigQuery Masked Reader role by the <code translate="no" dir="ltr">Confidential</code> policy tag, which is the parent of the <code translate="no" dir="ltr">Financial</code> policy tag.</p> <p>A user who is not a member of either of those roles gets an access denied error if they try to query the annotated column.</p> <p>In contrast with the preceding scenario, take the policy tag and data policy configuration shown in Figure 5:</p> <p><img src="/static/bigquery/images/data-masking-inheritance2.png" alt="Evaluating user access when Fine-Grained Reader is granted at a higher level of the taxonomy and Masked Reader is granted at a lower level of the taxonomy." width="600" class="image"> </p> <p><strong>Figure 5.</strong> Policy tag and data policy configuration.</p> <p>You have the same situation as shown in Figure 4, but the user is granted the Fine-Grained Reader role at a higher level of the policy tag hierarchy, and the Masked Reader role at a lower level of the policy tag hierarchy. Because of this, the query returns masked column data for this user. This happens even though the user is granted the Fine-Grained Reader role further up the tag hierarchy, because the service uses the first assigned role it encounters as it ascends the policy tag hierarchy to check for user access.</p> <p>If you want to create a single data policy and have it apply to several levels of a policy tag hierarchy, you can set the data policy on the policy tag that represents the topmost hierarchy level to which it should apply. For example, take a taxonomy with the following structure:</p> <ul> <li>Policy tag 1 <ul> <li>Policy tag 1a <ul> <li>Policy tag 1ai</li> </ul></li> <li>Policy tag 1b <ul> <li>Policy tag 1bi</li> <li>Policy tag 1bii</li> </ul></li> </ul></li> </ul> <p>If you want a data policy to apply to all of these policy tags, set the data policy on policy tag 1. If you want a data policy to apply to policy tag 1b and its children, set the data policy on policy tag 1b.</p> <h2 id="data_masking_with_incompatible_features" data-text="Data masking with incompatible features" tabindex="-1">Data masking with incompatible features</h2> <p>When you use <a href="#compatibility">BigQuery features that aren't compatible with data masking</a>, the service treats the masked column as a secured column, and only grants access to users who have the Data Catalog Fine-Grained Reader role.</p> <p>For example, take the policy tag and data policy configuration shown in Figure 6:</p> <p><img src="/static/bigquery/images/data-masking-fallback.png" alt="The policy tag associated with the column is evaluated to determine if the user has permission to access unmasked data." width="600" class="image"> </p> <p><strong>Figure 6.</strong> Policy tag and data policy configuration.</p> <p>You have a table column that is annotated with the <code translate="no" dir="ltr">Financial</code> policy tag, and a user who is a member of the analysts@example.com group. When this user tries to access the annotated column through one of the incompatible features, they get an access denied error. This is because they are granted the BigQuery Masked Reader by <code translate="no" dir="ltr">Financial</code> policy tag, but in this case, they must have the Data Catalog Fine-Grained Reader role.
