创建常规自定义字典检测器

自定义字典提供了匹配字词或短语列表的简单而强大的功能。您可以将自定义字典用作检测器，也可以将其用作内置检测器的例外列表。您还可使用自定义字典来强化内置的 infoType 检测器，以匹配其他结果。

本部分介绍了如何根据字词列表创建常规自定义字典检测器。

字典自定义 infoType 检测器详解

如 API 概览中所述，要创建字典自定义 infoType 检测器，需要定义一个包含下列内容的 CustomInfoType 对象：

  • 您希望在 InfoType 对象中为自定义 infoType 检测器指定的名称。
  • （可选）Likelihood 值。如果省略此字段，则字典项的匹配项将返回默认可能性 VERY_LIKELY。
  • （可选）DetectionRule 对象或热词规则。这些规则可对在指定热词一定邻近范围内的结果调整可能性。详细了解自定义匹配可能性中的热词规则。

  • （可选）SensitivityScore 值。如果省略此字段，则字典项的匹配项将返回默认敏感度级别 HIGH。

    敏感度得分用于数据分析。在分析数据时，敏感数据保护功能会使用 infoType 的敏感度得分来计算敏感度级别。

  • Dictionary - 可以是包含要扫描的字词列表的 WordList，也可以是要扫描的字词列表（以换行符分隔）所在单个文本文件的 CloudStoragePath。

作为一个 JSON 对象，包含所有可选组件的字典自定义 infoType 检测器如下所示：此 JSON 包含存储在 Cloud Storage 中的字典文本文件的路径。如需查看内嵌字词列表，请参阅本主题后面的示例部分。

{
  "customInfoTypes":[
    {
      "infoType":{
        "name":"CUSTOM_INFOTYPE_NAME"
      },
      "likelihood":"LIKELIHOOD_LEVEL",
      "detectionRules":[
        {
          "hotwordRule":{
            HOTWORD_RULE
          }
        },
        ...
      ],
      "sensitivityScore":{
          "score": "SENSITIVITY_SCORE"
        },
      "dictionary":
      {
        "cloudStoragePath":
        {
          "path": "gs://PATH_TO_TXT_FILE"
        }
      }
    }
  ],
  ...
}

字典匹配详情

以下是关于敏感数据保护如何与字典字词和短语进行匹配的指南。以下要点同时适用于常规自定义字典和大型自定义字典：

  • 字典字词不区分大小写。如果您的字典包含 Abby，将匹配 abby、ABBY、Abby 等。
  • 扫描匹配项时，在字典或要扫描的内容中，除了 Unicode 基本多语言平面中包含的字母、数字和其他字母字符外，其他所有字符一律被视为空格。如果您的字典扫描 Abby Abernathy，将匹配 abby abernathy、Abby, Abernathy、Abby (ABERNATHY) 等。
  • 任何匹配项两侧的字符均必须与字词中相邻字符的类型（字母或数字）不同。如果您的字典扫描 Abi，将匹配 Abi904 的前三个字符，但不匹配 Abigail 的前三个字符。
  • 如果字典字词包含 Unicode 标准补充多语言平面中的字符，则可能会产生意外结果。此类字符的示例包括表情符号、科学符号和历史文字。

字母、数字和其他字母字符的定义如下：

  • 字母：Unicode 规范中常规类别为 Lu、Ll、Lt、Lm 或 Lo 的字符
  • 数字：Unicode 规范中属于一般类别 Nd 的字符
  • 其他字母字符：Unicode 规范中属于一般类别 Nl 或具有 Unicode 标准中定义的贡献属性 Other_Alphabetic 的字符

示例

简单字词列表

假设您的数据中包括患者在就诊期间接受治疗的病房。在特定数据集中，这些位置可能被视为敏感数据，但是敏感数据保护的内置检测器不会捕捉它们。

病房列为：

  • "RM-Orange"
  • "RM-Yellow"
  • "RM-Green"

  "item":{
    "value":"Patient was seen in RM-YELLOW then transferred to rm green."

JSON 输出：

当我们使用 POST 将此 JSON 发布到 content:deidentify 时，将返回以下 JSON 响应：

{
  "item":{
    "value":"jack@example.org accessed customer record of [EMAIL_ADDRESS]"
  },
  "overview":{
    "transformedBytes":"17",
    "transformationSummaries":[
      {
        "infoType":{
          "name":"EMAIL_ADDRESS"
        },
        "transformation":{
          "replaceWithInfoTypeConfig":{

          }
        },
        "results":[
          {
            "count":"1",
            "code":"SUCCESS"
          }
        ],
        "transformedBytes":"17"
      }
    ]
  }
}

输出结果正确识别出了 user1@example.com 与 infoType 检测器 EMAIL_ADDRESS 匹配，jack@example.org 与自定义 infoType 检测器 DEVELOPER_EMAIL 匹配。请注意，由于我们选择仅转换 EMAIL_ADDRESS，因此 jack@example.org 保持不变。

强化内置的 infoType 检测器

请设想一下内置的 infoType 检测器未返回正确值的情景。例如，您希望返回人名匹配项，但敏感数据保护的内置 PERSON_NAME 检测器无法返回数据集中一些常见人名的匹配项。

借助敏感数据保护功能，您可以通过在自定义 infoType 检测器的声明中包含内置检测器来强化内置的 infoType 检测器，如下例所示。下面的代码段展示了如何配置敏感数据保护来使内置 infoType 检测器 PERSON_NAME 额外匹配出姓名“Quasimodo”：
