Native semantic categories of sensitive data classification¶

The following sections list semantic categories that are provided by Snowflake. These native semantic categories identify common types of sensitive attributes such as names and addresses. If you need to classify attributes that are not supported natively, see Create custom categories for sensitive data.

Each section corresponds to a privacy category. For example, the Identifier categories section lists the native semantic categories that are assigned to data that belongs to the IDENTIFIER privacy category.

Important

Multiple semantic categories can be considered “Sensitive Personal Data”, “Special Categories of Data”, or similar terms under various laws and regulations, and might require additional protections or controls.

About semantic subcategories¶

If Snowflake identifies that the type of sensitive data is specific to a locale, it assigns the data a semantic subcategory. For example, suppose Snowflake identifies a social security number (SSN), which is an identifier in the United States (US). The native semantic category is NATIONAL_IDENTIFIER and the semantic subcategory is US_SSN.

Semantic subcategories are prefixed with the two-letter country code of a locale, as defined by ISO 3166-1 alpha-2.

After classification, you can find the semantic subcategory in the Details field of the JSON object returned by the classification process. For more information about viewing this response object, see Use SQL to view results.
