Cloud Data Loss Prevention (Cloud DLP) 現已併入機密資料保護。API 名稱維持不變：Cloud Data Loss Prevention API (DLP API)。如要瞭解構成 Sensitive Data Protection 的服務，請參閱「Sensitive Data Protection 總覽」。

使用 infoType 檢查圖片是否含有機密資料

如要檢查圖片是否含有機密資料，請將 base64 編碼圖片提交至 Cloud DLP API 的 content.inspect 方法。除非您指定要搜尋的資訊類型 (infoType)，否則 Cloud DLP 會搜尋最常見的 infoType。
