Example 1 with CharacterMaskConfig

use of com.google.privacy.dlp.v2.CharacterMaskConfig in project java-docs-samples by GoogleCloudPlatform.

the class DeIdentification method deIdentifyWithMask.

// [START dlp_deidentify_masking]
/**
 * Deidentify a string by masking sensitive information with a character using the DLP API.
 *
 * @param string The string to deidentify.
 * @param maskingCharacter (Optional) The character to mask sensitive data with.
 * @param numberToMask (Optional) The number of characters' worth of sensitive data to mask.
 *     Omitting this value or setting it to 0 masks all sensitive chars.
 * @param projectId ID of Google Cloud project to run the API under.
