Sensitive Data Protection 可帮助您了解、管理和保护敏感数据。
借助敏感数据保护，您可以轻松地分类和隐去基于文本的内容和图片中所含的敏感数据，包括存储在Google Cloud 存储库中的内容。
文本分类
假设存在以下文本输入：
Please update my records with the following information:
Email address: foo@example.com
National Provider Identifier: 1245319599
Driver's license: AC333991
Please update my records with the following information:
Email address: foo@example.com
National Provider Identifier: 1245319599
Driver's license: AC333991
使用占位符“***”输出的示例：
Please update my records with the following information:
Email address: ***
National Provider Identifier: ***
Driver's license: ***
图片分类
Sensitive Data Protection 使用光学字符识别 (OCR) 技术在分类之前识别文本。与文本分类类似，它会返回结果，但它还会在找到文本的位置添加边界框。

Similar to text\nclassification, it returns findings, but it also adds a bounding box\nwhere the text was found.\n\nStorage classification\n----------------------\n\nStorage classification scans data stored in Cloud Storage, Firestore in Datastore mode (Datastore),\nand BigQuery. Instead of streaming data into Sensitive Data Protection, you\nspecify in your request the storage location for the Cloud Storage\nbucket, Datastore kind, or BigQuery table you\nwant Sensitive Data Protection to scan.\n\nWhen scanning files in Cloud Storage locations, Sensitive Data Protection\nsupports scanning of binary, text, image, Microsoft Word, Microsoft Excel,\nMicrosoft Powerpoint, PDF, and Apache Avro\nfiles. A list of file extensions for the file types within Cloud Storage\nthat Sensitive Data Protection can scan is available on the API reference page for\n[`FileType`](/sensitive-data-protection/docs/reference/rest/v2/FileType).\nFiles of types that are unrecognized are scanned as binary files.\n\nThe results of the scan can be either saved to a new BigQuery\ntable or published to a Pub/Sub topic. From there, you can use\nbuilt-in BigQuery tools to run rich SQL analytics or tools\nsuch as Looker Studio to generate reports.\n\nFor more information about scanning storage repositories for sensitive data\nusing Sensitive Data Protection, see [Inspecting storage and databases for\nsensitive data](/sensitive-data-protection/docs/inspecting-storage).\n\nFor more information about visualizing scan results using other Google Cloud\ntools, see [Analyzing and reporting on Sensitive Data Protection\nfindings](/sensitive-data-protection/docs/analyzing-and-reporting).\n\nWhat's next\n-----------\n\n- Learn more about [image inspection and redaction](/sensitive-data-protection/docs/concepts-image-redaction).\n- Learn about [transformation methods](/sensitive-data-protection/docs/transformations-reference) that you can use with Sensitive Data Protection.\n- Work through the [Redacting Sensitive Data with Sensitive Data Protection](https://www.cloudskillsboost.google/focuses/46234?parent=catalog) codelab.\n- Learn more about [creating a de-identified copy of data in\n storage](/sensitive-data-protection/docs/concepts-deidentify-storage)."]]
