训练和测试旨在检测洗钱行为的模型

了解如何使用开发机器上或 Google Cloud 控制台中的命令行工具执行反洗钱 AI 中的基本操作。

在本指南中，您将以 BigQuery 表的形式提供示例银行交易数据，作为 AML AI 的输入。API 会输出包含回测结果和预测结果的 BigQuery 表。其结果用于分析通过组织资金结构进行洗钱的示例方。

  },
  "done": false
}

如果成功，响应正文会包含一个长时间运行的操作，其中包含可用于检索异步操作的正在进行状态的 ID。复制返回的 OPERATION_ID 以便在下一部分中使用。

查看结果

使用 projects.locations.operations.get 方法检查是否已创建实例。如果响应包含 "done": false，请重复该命令，直到响应包含 "done": true。

本指南中的操作可能需要几分钟到几小时才能完成。在本指南中，您必须等到某项操作完成后才能继续操作，因为 API 会将某些方法的输出用作其他方法的输入。

在使用任何请求数据之前，请先进行以下替换：

  • OPERATION_ID：操作的标识符

    "state": "ACTIVE"
  }
}

授予对 CMEK 密钥的访问权限

API 会自动在您的项目中创建一个服务帐号。服务帐号需要访问 CMEK 密钥，才能使用该密钥加密和解密基础数据。授予对密钥的访问权限。

gcloud kms keys add-iam-policy-binding "projects/PROJECT_ID/locations/LOCATION/keyRings/my-key-ring/cryptoKeys/my-key" \
  --keyring "projects/PROJECT_ID/locations/LOCATION/keyRings/my-key-ring" \
  --location "LOCATION" \
  --member "serviceAccount:service-PROJECT_NUMBER@gcp-sa-financialservices.iam.gserviceaccount.com" \
  --role="roles/cloudkms.cryptoKeyEncrypterDecrypter" \
  --project="PROJECT_ID"

创建 BigQuery 数据集

本部分介绍如何创建输入和输出 BigQuery 数据集，然后将示例银行数据复制到输入数据集中。

创建输出数据集

运行以下命令创建数据集，该数据集用于向其发送 AML 流水线输出。

bq mk \
  --location=LOCATION \
  --project_id=PROJECT_ID \
  my_bq_output_dataset

创建输入数据集

运行以下命令，创建要将示例银行表复制到其中的数据集。

bq mk \
  --location=LOCATION \
  --project_id=PROJECT_ID \
  my_bq_input_dataset

复制示例数据集

示例银行数据作为 BigQuery 公共数据集提供。此数据集的主要功能包括：

  • 100,000 方
  • 从 2020 年 1 月 1 日到 2023 年 1 月 1 日的核心时间范围，以及额外的 24 个月的回溯期
  • 每月 300 个排除和 20 个正风险案例
  • 具有以下属性的风险案例：
    • 一半的正风险案例都与 AML_PROCESS_START 事件之前的两个月内发生的活动有关
    • 另一半涵盖 AML_PROCESS_START 事件之前的两个月内收款金额最高的各方
    • 随机生成负例
    • 风险用例为相反状态生成 0.1% 的几率（例如，随机为正例的一方，或有结构化活动或收入最高且被报告为负例的一方）

  1. 运行以下命令，将示例银行数据复制到您创建的输入数据集。

    bq mk --transfer_config \
  --project_id="PROJECT_ID" \
  --data_source=cross_region_copy \
  --target_dataset="my_bq_input_dataset" \
  --display_name="Copy the AML sample dataset." \
  --schedule=None \
  --params='{
    "source_project_id":"bigquery-public-data",
    "source_dataset_id":"aml_ai_input_dataset",
    "overwrite_destination_table":"true"
  }'

  2. 在 Google Cloud 控制台中打开 BigQuery。

    前往 Google Cloud 控制台

  3. 在探索器窗格中查找并展开输入数据集。几分钟后，您应该会在输入数据集中看到表。您还可以通过从 BigQuery 导航菜单中选择数据传输来查看转移状态。AML 架构在 AML 输入数据模型中定义。

授予对 BigQuery 数据集的访问权限

API 会自动在您的项目中创建一个服务帐号。该服务帐号需要能够访问 BigQuery 输入和输出数据集。

  1. 在开发机器上安装 jq。如果您无法在开发机器上安装 jq，可以使用 Cloud Shell 或 BigQuery 文档中提供的其他授予对资源的访问权限的方法。
  2. 运行以下命令以授予对输入数据集及其表的读取权限。
# Request the current access permissions on the BigQuery dataset and store them in a temp file.
bq show --format=prettyjson "PROJECT_ID:my_bq_input_dataset" | jq '.access+=[{"role":"READER","userByEmail":"service-PROJECT_NUMBER@gcp-sa-financialservices.iam.gserviceaccount.com" }]'> /tmp/mydataset.json
# Update the BigQuery dataset access permissions using the temp file.
bq update --source /tmp/mydataset.json "PROJECT_ID:my_bq_input_dataset"

# Grant the API read access to the BigQuery table if the table is provided.
for table in party account_party_link transaction risk_case_event party_supplementary_data
do
   [ -n table ] && bq add-iam-policy-binding \
     --member="serviceAccount:service-PROJECT_NUMBER@gcp-sa-financialservices.iam.gserviceaccount.com" --role="roles/bigquery.dataViewer" \
     PROJECT_ID:my_bq_input_dataset.${table}
done

运行以下命令以授予对输出数据集的写入权限。

# Request the current access permissions on the BigQuery dataset and store them in a temp file.
bq show --format=prettyjson "PROJECT_ID:my_bq_output_dataset" | jq '.access+=[{"role":"roles/bigquery.dataEditor","userByEmail":"service-PROJECT_NUMBER@gcp-sa-financialservices.iam.gserviceaccount.com" }]'> /tmp/mydataset.json
# Update the BigQuery dataset access permissions using the temp file.
bq update --source /tmp/mydataset.json "PROJECT_ID:my_bq_output_dataset"

在 Google Cloud 控制台中分析单个结构化案例

  1. 在 Google Cloud 控制台中打开 BigQuery。确保已选择 SQL 工作区。

    前往 Google Cloud 控制台

  2. BigQuery 页面包含三个主要部分：

    • BigQuery 导航菜单
    • 浏览器窗格
    • “详细信息”窗格

    在“详细信息”窗格中，点击编写新查询以打开查询编辑器。

    编写一个新查询。

  3. 将以下 SQL 语句复制到编辑器中，然后点击运行。

    SELECT *
FROM `PROJECT_ID.my_bq_input_dataset.transaction`
WHERE account_id = '1E60OAUNKP84WDKB' AND DATE_TRUNC(book_time, MONTH) = "2022-08-01"
ORDER by book_time

    此对账单已于 2022 年 8 月检查账号 ID 1E60OAUNKP84WDKB。此帐号已与第三方 ID EGS4NJD38JZ8NTL8 相关联。您可以使用 AccountPartyLink 表来查找指定帐号 ID 对应的参与方 ID。

    交易数据显示了针对单个帐号的一系列圆形交易，这些看起来很可疑。

    某一方的可疑交易数据。

  4. 将以下 SQL 语句复制到编辑器中，然后点击运行。

    SELECT *
FROM `PROJECT_ID.my_bq_input_dataset.risk_case_event`
WHERE party_id = 'EGS4NJD38JZ8NTL8'

    此声明表明存在导致该方退出的风险案例。风险案例在可疑活动两个月后开始。

    单个方的风险案例事件。

  5. 将以下 SQL 语句复制到编辑器中，然后点击运行。

    SELECT *
FROM `PROJECT_ID.my_bq_output_dataset.my_prediction_results`
WHERE party_id = 'EGS4NJD38JZ8NTL8'
ORDER BY risk_period_end_time

    通过查看预测结果，您可以看到在可疑活动后的几个月内，该方的风险得分从近零（注意指数值）跳到高值。您实际看到的结果可能与显示的结果不同。

    某一方的风险得分增加。

    风险评分并非概率，风险得分应始终相对于其他风险得分进行评估。例如，在其他风险得分较低的情况下，一个看似较小的值可以视为正数。

  6. 将以下 SQL 语句复制到编辑器中，然后点击运行。

    SELECT *
FROM `PROJECT_ID.my_bq_output_dataset.my_prediction_results_explainability`
WHERE party_id = 'EGS4NJD38JZ8NTL8'
AND risk_period_end_time = '2022-10-01'

    通过检查可解释性结果，您可以看到正确的特征系列得分最高。

    预测结果的可解释性结果。

如需删除实例，请使用 projects.locations.instances.delete 方法。

如需发送请求，请选择以下方式之一：

curl

执行以下命令： 

curl -X DELETE \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     "https://financialservices.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/instances/my-instance"

PowerShell

执行以下命令： 

$cred = gcloud auth print-access-token
$headers = @{ "Authorization" = "Bearer $cred" }

Invoke-WebRequest `
    -Method DELETE `
    -Headers $headers `
    -Uri "https://financialservices.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/instances/my-instance" | Select-Object -Expand Content
