借助 Cloud Data Loss Prevention (DLP) 的内置 infoType 检测器，您可以有效地查找常见类型的敏感数据。借助自定义 infoType 检测器，您可以全面定制自己的敏感数据检测器。检查规则可通过修改所给定的 infoType 检测器的检测机制，帮助优化 Cloud DLP 返回的扫描结果。
如果要从内置 infoType 检测器返回的结果中排除或包含更多值，您可以从头开始创建新的自定义 infoType，并定义 Cloud DLP 应遵循的所有条件。或者，您也可以根据自己指定的条件，优化 Cloud DLP 的内置或自定义检测器返回的结果。您可添加检查规则来实现此目的，它们有助于减少噪声、提高精确率和召回率，或者调整扫描结果的确定性。
本主题讨论如何使用两种类型的检查规则来排除某些结果或添加额外结果，所有操作均根据您指定的自定义条件执行。本主题还将介绍几种您可能需要更改现有 infoType 检测器的场景。
这两种检查规则是：
排除规则
排除规则对以下情况非常有用：
- 您希望排除结果中因 infoType 检测器重叠而导致的重复的扫描匹配项。例如，您要扫描电子邮件地址和电话号码，但却获得两个带电话号码的电子邮件地址匹配项，例如“206-555-0764@example.org”。
- 您在扫描结果中遇到了噪声。例如，您发现在扫描合法电子邮件地址时，同一虚拟电子邮件地址（例如“example@example.com”）或网域（例如“example.com”）返回的次数过多。
- 您有一个希望从结果中排除的术语、短语或字符组合的列表。
排除规则 API 概览
Cloud DLP 在 ExclusionRule 对象中定义排除规则。在 ExclusionRule 中，您可指定下列任一对象：
Dictionary对象，表示排除规则是常规字典规则。Regex对象，表示排除规则是正则表达式规则。ExcludeInfoTypes对象，包含一组 infoType 检测器。如果此处所列的任何 infoType 检测器匹配到结果，就会将结果从扫描结果中排除。
排除规则示例场景
下列各个 JSON 代码段均说明如何针对指定场景配置 Cloud DLP。
在 EMAIL_ADDRESS 检测器扫描中忽略特定电子邮件地址
以下采用多种语言的 JSON 代码段和代码说明如何通过 InspectConfig 向 Cloud DLP 指示应在使用 infoType 检测器 EMAIL_ADDRESS 的扫描中避免匹配“example@example.com”：

忽略包含子字符串“TEST”的扫描匹配项
以下采用多种语言的 JSON 代码段和代码说明如何通过 InspectConfig 向 Cloud DLP 指示应从指定的 infoType 列表中排除包含令牌“TEST”的任何结果。
请注意，这相当于将“TEST”作为令牌（而非子字符串）匹配，因此，虽然“TEST@email.com”之类的内容会匹配，但“TESTER@email.com”则不会。如果需要匹配子字符串，请在排除规则中使用正则表达式，而不是字典。

在与自定义检测器重叠的 PERSON_NAME 检测器扫描中忽略扫描匹配项
在此场景中，如果某匹配项还在使用代码段第一部分中定义的自定义正则表达式检测器的扫描中得到匹配，则用户不希望使用内置检测器 PERSON_NAME 的 Cloud DLP 扫描返回该匹配项。
以下采用多种语言的 JSON 代码段和代码在 InspectConfig 中同时指定了自定义正则表达式检测器和排除规则。自定义正则表达式检测器用于指定要从结果中排除的姓名。排除规则指定如果针对 PERSON_NAME 的扫描返回的任何结果也被自定义正则表达式检测器匹配到，则忽略这些结果。请注意，VIP_DETECTOR 在此情况下标记为 EXCLUSION_TYPE_EXCLUDE，因此它本身不产生结果。它只会影响 PERSON_NAME 检测器生成的结果。

}热词规则
热词规则对以下情况非常有用：
- 您想要根据匹配项与热词的邻近度来更改分配给扫描匹配项的可能性值。例如，您希望根据患者姓名与“患者”一词的邻近度，为患者姓名匹配项设置更高的可能性值。
- 检查结构化的表格数据时，您想要根据列标题名称来更改分配给匹配项的可能性值。例如，您希望为标题为
ACCOUNT_ID的列中的US_SOCIAL_SECURITY_NUMBER设置更高的可能性值。
热词规则 API 概览
在 Cloud DLP 的 InspectionRule 对象中，您可以指定一个 HotwordRule 对象，用于为在热词的一定邻近范围内的结果调整可能性。
InspectionRule 对象在 InspectionRuleSet 对象中分组为“规则集”，组中还有规则集所适用的 infoType 检测器列表。规则集中的规则按指定顺序进行应用。
热词规则示例场景
以下代码段说明如何针对特定场景配置 Cloud DLP。
提高旁边有热词“患者”的 PERSON_NAME 匹配项的可能性
以下采用多种语言的 JSON 代码段和代码说明了如何使用 InspectConfig 属性来扫描医疗数据库中的患者姓名。您可以使用 Cloud DLP 的内置 infoType 检测器 PERSON_NAME，但这会导致 Cloud DLP 匹配所有人名，而不仅仅是患者姓名。为解决此问题，您可以添加一条热词规则，用于在潜在匹配项第一个字符的一定邻近字符范围内查找“患者”一词。然后，您可以向匹配该模式的结果分配“可能性极大”(very likely) 这一可能性，因为这些结果符合您的特殊条件。通过在 InspectConfig 中将 Likelihood 的最小值设为 VERY_LIKELY，可确保结果中仅返回符合此配置的匹配项。

}重叠的 infoType 检测器
可以定义与内置 infoType 检测器同名的自定义 infoType 检测器。如热词规则示例场景部分中的示例所示，如果您创建与内置 infoType 同名的自定义 infoType 检测器，则新 infoType 检测器检测到的任何结果都会添加到内置检测器检测到的结果中。仅当 InspectConfig 对象的 infoType 列表中指定了内置 infoType 时，才会出现此情况。
创建新的自定义 infoType 检测器时，请对示例内容进行充分测试，确保其按预期工作。
