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虚拟形象、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股票。我们怀疑有一群“罗宾汉猫”正在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

使用 BigQuery 持续查询检测实时数据流中的异常，并将其推送到 Spanner。
使用 Spanner Graph 追踪财务关系，调查欺诈团伙。
使用 Spanner 向量搜索查找相似的个人资料描述，从而识别机器人账号。
使用 BigQuery Graph 分析海量通信日志，揭示协调图。

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各项服务。

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。
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。
在 Cloud 控制台首页中查找项目 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。

前往 Google Cloud Shell。
如果出现提示，请点击授权。
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

现在，您将在 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

创建 game_analytics BigQuery 数据集：

bq mk -d --location=US game_analytics

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

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。

创建 Spanner 实例：

gcloud spanner instances create game-instance \
    --config=regional-us-central1 \
    --description="Game Instance" \
    --processing-units=100 \
    --edition=ENTERPRISE

创建 Spanner 数据库 game-db：

gcloud spanner databases create game-db --instance=game-instance

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

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

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

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 中的遥测数据。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 ENTERPRISE 版或更高级别的资源。

如果预订可用，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：找出幕后主使

此查询会跟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 Boss 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”汇款且被标记为存在可疑活动的玩家。

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

这些是真实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”的描述过于相似的账号。

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。如果这些账号的描述类似，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）。

如果您点击结果中的 GCS 链接，您将看到播放器的图片：

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“PROJECT_ID”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 没有访问或使用端点的权限…”），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，以便我们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 来直观呈现欺诈团伙。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图表可视化效果。

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，则可以删除整个项目：

gcloud projects delete <YOUR_PROJECT_ID>

8. 恭喜！
