Spanner 和 BigQuery：实时欺诈防御盾

1. 简介

欢迎来到 Petverse 的后端，这是一款多人在线游戏，玩家可以在其中创建动物头像、探索世界并交易游戏代币。

最近，游戏的经济系统面临威胁。大量资金正从富有的狗狗玩家的账户中流失，全部转换为优质金枪鱼库存。我们怀疑有一群“罗宾汉猫”，它们从富有的猎犬那里偷东西来喂养猫群。

在此 Codelab 中，您将构建一个实时欺诈防御盾，以捕获主谋及其自动化机器人团伙。您将体验 Spanner 中的运营数据如何与 BigQuery 中的分析数据融合，从而通过图表 (GQL) 和关系型查询检测和调查复杂的欺诈模式。

您将执行的操作

所需条件

  • 启用了结算功能的 Google Cloud 项目。
  • 具备 SQL、终端命令和 Python 的基础知识。
  • 您可能需要 GitHub 账号（代码托管在 GitHub 上）。

受众群体：中级开发者、数据工程师和架构师。

预计总时长：45 至 60 分钟。

费用估算：本 Codelab 中创建的资源产生的费用应低于 5 美元。

2. 准备工作 / 设置

创建或选择 Google Cloud 项目

您需要一个启用了结算功能的 Google Cloud 项目，才能使用本实验所需的服务。

  1. 在 Google Cloud 控制台的项目选择器页面上，选择或创建一个 Google Cloud 项目。
  2. 确保您的 Cloud 项目已启用结算功能。了解如何验证是否已启用结算功能。
  3. 在 Cloud 控制台首页中找到您的项目 ID

Cloud 控制台首页

启动 Cloud Shell

您将使用 Google Cloud Shell 作为执行环境。Cloud Shell 预安装了 gcloud、git 和其他所需工具。

  1. 前往 Google Cloud Shell。
  2. 如果出现提示，请点击授权。
  3. 在 Cloud Shell 终端中设置环境变量，确保您正在自己的项目中操作：
export PROJECT_ID=<YOUR_PROJECT_ID>
gcloud config set project $PROJECT_ID

Cloud Shell：使用 gcloud config 设置项目

启用必要的 API

运行以下命令，以启用 Spanner、BigQuery 和 Vertex AI 的 API：

gcloud services enable spanner.googleapis.com \
    bigquery.googleapis.com \
    aiplatform.googleapis.com \
    run.googleapis.com

克隆代码库

克隆包含应用代码和示例架构的代码库：

git clone https://github.com/GoogleCloudPlatform/cloud-spanner-samples.git
cd cloud-spanner-samples/spanner-bq-fraud-defense

3. 预配基础设施

您现在将在 BigQuery 中设置数据仓库，并在 Spanner 中设置运营数据库。

设置 BigQuery 数据集和连接

BigQuery 将分析游戏中的遥测数据流。

在 Google Cloud Shell 的控制台中，继续运行以下命令，以确保项目 ID 仍处于设置状态：

export PROJECT_ID=<YOUR_PROJECT_ID>
gcloud config set project $PROJECT_ID
  1. 创建 game_analytics BigQuery 数据集：
bq mk -d --location=US game_analytics
  1. 创建连接以连接到存储分区和（可选）Spanner：
bq mk --connection --location=US --project_id=$PROJECT_ID \
    --connection_type=CLOUD_RESOURCE unicorn-connection
  1. 使用架构文件为 GameplayTelemetry、AccountSignals、Players 和 ChatLogs 表创建架构：
bq query --use_legacy_sql=false < bq_schema.sql

设置 Spanner

Google Cloud Spanner 将处理运营实时交易。在本实验中，我们将使用经济实惠的 100 个处理单元 (PU) 实例。

  1. 创建 Spanner 实例：
gcloud spanner instances create game-instance \
    --config=regional-us-central1 \
    --description="Game Instance" \
    --processing-units=100 \
    --edition=ENTERPRISE
  1. 创建 Spanner 数据库 game-db：
gcloud spanner databases create game-db --instance=game-instance
  1. 使用应用表（Players、Transactions、AccountSignals）和属性图（PlayerNetwork）更新 Spanner 架构：
gcloud spanner databases ddl update game-db --instance=game-instance --ddl-file=spanner_schema.sql
  1. 为多模态向量搜索创建 AvatarSearchIndex：
gcloud spanner databases ddl update game-db --instance=game-instance \
    --ddl="CREATE SEARCH INDEX AvatarSearchIndex ON Players(AvatarDescriptionTokens)"

将数据导入 BigQuery

  1. 将演示数据导入 BigQuery：
bq load --source_format=AVRO game_analytics.GameplayTelemetry gs://sample-data-and-media/spanner-bq-fraud-heist/GameplayTelemetry
bq load --source_format=AVRO game_analytics.AccountSignals gs://sample-data-and-media/spanner-bq-fraud-heist/AccountSignals
bq load --source_format=AVRO game_analytics.Players gs://sample-data-and-media/spanner-bq-fraud-heist/Players
bq load --source_format=AVRO game_analytics.ChatLogs gs://sample-data-and-media/spanner-bq-fraud-heist/ChatLogs
  1. 前往 BigQuery 控制台，然后探索 game_analytics 数据集中的数据。

BigQuery 控制台

将数据导入 Spanner

前往 Spanner 控制台，然后探索 game-db 数据库中的数据。

点击 Spanner Studio，然后打开新查询 (+)。

Spanner 控制台

将以下 INSERT 语句粘贴到查询编辑器中，然后点击运行：

这可能需要几分钟时间才能运行完毕。完成后，您应该能够预览数据。

Spanner Studio 中的数据预览

4. Watchdog（BigQuery 持续查询和 Spanner 同步）

我们的第一道防线是流式传输到 BigQuery 的遥测数据。我们希望监控可疑移动（例如，不可能的距离），并实时将提醒推送回 Spanner。

在实际应用场景中，您可以使用 BigQuery 持续查询和反向 ETL 来流式传输这些数据。不过，这需要预留使用企业版或更高级别。

如果预留可用，该命令将如下所示。如果您尚未设置预留，则无需将此内容复制到控制台中：

EXPORT DATA
  OPTIONS (
    uri = 'https://spanner.googleapis.com/projects/<YOUR_PROJECT_ID>/instances/game-instance/databases/game-db',
    format='CLOUD_SPANNER',
    spanner_options="""{ "table": "AccountSignals" }"""
  ) AS
SELECT
  GENERATE_UUID() as SignalId,
  PlayerId,
  'SUSPICIOUS_MOVEMENT' as AlertType,
  CURRENT_TIMESTAMP() as EventTime
FROM `game_analytics.GameplayTelemetry`
WHERE
  EventType = 'player_move'
  AND (LocationX > 1000 OR LocationY > 1000);

如需创建持续查询，您可以在 BigQuery 控制台 SQL 工作区中依次点击更多 > 创建持续查询。

此查询充当反向 ETL 引擎，可确保我们的事务系统 (Spanner) 立即了解分析系统 (BigQuery) 中检测到的异常情况。

在本实验中，我们人为地向 Spanner 插入了一些事务。

5. 多模态侦探（Spanner Graph 和向量搜索）

现在，Spanner 收到“高风险”信号，您可以调查欺诈团伙了。我们将使用 Spanner Graph 可视化金融网络并找到幕后主使。

在 Spanner Studio 中运行这些查询

图表：找到主导者

此查询会追踪受害者向窃贼转账，然后窃贼向头目节点转账的金融交易网络。按首领分组，并对战利品求和。

将其复制到 Spanner Studio 中，然后点击运行。

GRAPH PlayerNetwork
MATCH (victim)-[:Transfers]->(thief)-[t:Transfers]->(boss)
RETURN
  boss.Name AS RingLeader, COUNT(t) AS TributesReceived,
  SUM(t.Amount) AS TotalLoot
GROUP BY RingLeader
ORDER BY TotalLoot DESC
LIMIT 5;

您应该会看到“Pixel”是获得赞扬最多的收件人。

多信号调查

接下来，我们将 Graph 结果与之前从 BigQuery 推送的实时行为信号联接起来。我们希望找到向“Pixel”汇款且被标记为有可疑活动的玩家。

SELECT DISTINCT
  p.Name,
  s.AlertType as BQ_Signal,
  s.EventTime as SignalTime
FROM GRAPH_TABLE (
  PlayerNetwork
  MATCH (associate:Players)-[:Transfers]->(boss:Players)
  WHERE boss.Name = 'Pixel'
  RETURN DISTINCT associate.Name
) as g
JOIN Players p
  ON p.Name = g.Name
JOIN AccountSignals s
  ON p.PlayerId = s.PlayerId
ORDER BY s.EventTime DESC;

向量搜索：识别机器人账号

这些是真人玩家还是有组织的机器人团伙？使用向量搜索功能来识别个人资料描述与“Pixel”的描述可疑地相似的账号。

SELECT
  Name, AvatarDescription,
  COSINE_DISTANCE(AvatarEmbedding, (SELECT AvatarEmbedding FROM Players WHERE Name = 'Pixel')) as Similarity
FROM Players
WHERE Name != 'Pixel'
ORDER BY Similarity ASC
LIMIT 5;

相似度得分越低，表示它们越接近“Pixel”向量。如果这些账号的说明类似，则很可能是机器人！

我们还可以在 MATCH 子句中应用标量函数：

GRAPH PlayerNetwork
MATCH (associate:Players)-[:Transfers]->(boss:Players)
WHERE boss.Name = 'Pixel'
ORDER BY (
  COSINE_DISTANCE(associate.AvatarEmbedding, (SELECT AvatarEmbedding FROM Players WHERE Name = 'Pixel'))
) ASC
RETURN DISTINCT associate.Name

6. 揭秘剧情（BigQuery 属性图和 GCS 集成）

我们抓到了主谋，但需要了解他们是如何协调这起大规模“金枪鱼抢劫案”的。我们将使用 BigQuery 属性图在 BigQuery 中跟踪通信模式，以查询游戏聊天记录。

在 BigQuery Studio 中运行以下查询：

BigQuery 属性图

跟踪“Pixel”与其他玩家之间的通信：

GRAPH game_analytics.CatChatNetwork
MATCH (p1:Players)-[c:Communicates]->(p2:Players)
WHERE p1.Name = 'Pixel' OR p2.Name = 'Pixel'
RETURN
  p1.Name AS Sender,
  p2.Name AS Receiver,
  c.Message,
  -- Resolving structured metadata from ObjectRef
  p1.ProfilePictureUrl.uri AS SenderProfilePic
ORDER BY Message DESC;

观察“Operation Fishbowl is a go”（鱼缸行动开始）和“Diverting funds to the central tuna reserve”（将资金转移到中央金枪鱼储备）等消息。您可以了解 BigQuery 属性图如何让您分析包含非结构化数据的通信（使用 ProfilePictureUrl.uri 的 GCS 图片引用）。

如果您下载图片或点击结果中的经过身份验证的 GCS 链接，您将看到该球员的图片：

Pixel 个人资料照片

此分析查询进一步比较了欺诈团伙成员之间的聊天模式和图片。

在运行此代码之前，请先声明一个多模态模型，以生成存储在 Cloud Storage 存储分区中的个人资料照片的嵌入。此模型通过初始设置中创建的连接进行连接，因此您还需要向附加到该连接的技术用户授予 Vertex AI 用户权限。

将 <> 替换为您的项目 ID。

GRANT `roles/aiplatform.user`
ON PROJECT `<<PROJECT_ID>>`
TO "connection:<<PROJECT_ID>>.us.unicorn-connection";

您现在可以创建连接了。

CREATE OR REPLACE MODEL `game_analytics.multimodal_model`
  REMOTE WITH CONNECTION `us.unicorn-connection`
  OPTIONS (ENDPOINT = 'multimodalembedding@001');

如果因权限错误而失败（即“bqcx-12345745345345@gcp-sa-bigquery-condel.iam.gserviceaccount.com 无权访问或使用端点…”），请等待几分钟，直到权限传播完毕，然后重试。

以下查询使用 AI.GENERATE_EMBEDDING 函数遍历存储分区中的图片并创建嵌入。然后，使用 COSINE_DISTANCE 对这些嵌入进行比较，以便更好地了解聊天记录和个人资料照片的相似程度。

直观呈现欺诈团伙

您可以使用笔记本和 Python Cell Magic 直观呈现欺诈团伙。这样，我们就可以轻松直观地查看图表结果。如需详细了解相关信息，请参阅可视化图表文档。

在 BigQuery Studio 中，依次点击更多 > 笔记本 > 空白笔记本。

创建笔记本

将以下内容粘贴到代码单元中：

!pip install bigquery-magics==0.12.1

使用 + 代码按钮创建一个新单元，然后粘贴以下内容：

%%bigquery --graph
GRAPH game_analytics.CatChatNetwork
MATCH p=(p1:Players)-[c:Communicates]-(p2:Players)
WHERE p1.Name = 'Pixel' OR p2.Name = 'Pixel'
RETURN TO_JSON(p) AS full_path

点击全部运行。大约一分钟后，您应该会看到通信网络的可视化图表。

图表可视化

7. 清理

为避免系统因本 Codelab 中使用的资源向您的 Google Cloud 账号收取费用，请删除您创建的资源。

删除 Spanner 实例

gcloud spanner instances delete game-instance

删除 BigQuery 数据集

bq rm -r -f -d game_analytics

或者，删除项目

如果您为此实验创建了一个新项目，可以删除整个项目：

gcloud projects delete <YOUR_PROJECT_ID>

8. 恭喜！

恭喜！您已成功使用 Spanner 和 BigQuery 构建了实时欺诈防御盾。

您学习了如何：

  • 使用 BigQuery 持续查询将实时数据洞见推送到 Spanner。
  • 使用 Spanner Graph 跟踪财务关系。
  • 使用 Spanner 向量搜索对非结构化数据执行相似度查询。
  • 使用 BigQuery 图跟踪通信网络。

接下来怎么做？
