Train and test models designed to detect money laundering

Train and test models designed to detect money laundering

In this guide, you learn how to train and test models designed to detect money laundering. You run through some basic steps to prepare your environment and create an AML AI instance. You then provide synthetic transaction data from one of Google's datasets (in the form of BigQuery tables) as input to AML AI. This input is used to train and backtest a model.

After registering parties for prediction, the API makes model predictions. The results are used to analyze an example party that is laundering money by structuring funds.

Before you begin

Important: After you create your project, the API is not automatically visible. You must contact your Google representative before you can enable the API.

Important: Completing this quickstart will result in charges to your Google Cloud account. For information on pricing, see the Pricing page. Note that the sample dataset used in this quickstart contains 100,000 parties.

Note: If you are going to use an existing project that you don't own, you may need your administrator to grant you certain permissions to access the existing project. For more information, see Creating and managing projects.

1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
2. Install the Google Cloud CLI.

3. To initialize the gcloud CLI, run the following command:

   gcloud init

4. Create or select a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   • Create a Google Cloud project:

     gcloud projects create PROJECT_ID

     Replace PROJECT_ID with a name for the Google Cloud project you are creating.

   • Select the Google Cloud project that you created:

     gcloud config set project PROJECT_ID

     Replace PROJECT_ID with your Google Cloud project name.

5. Make sure that billing is enabled for your Google Cloud project.

6. Enable the required APIs:

   gcloud services enable financialservices.googleapis.com bigquery.googleapis.com cloudkms.googleapis.com bigquerydatatransfer.googleapis.com

7. If you're using a local shell, then create local authentication credentials for your user account:

   gcloud auth application-default login

   You don't need to do this if you're using Cloud Shell.

8. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/financialservices.admin, roles/cloudkms.admin, roles/bigquery.admin

   gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE

   • Replace PROJECT_ID with your project ID.

   • Replace USER_IDENTIFIER with the identifier for your user account. For example, user:[e-mail].

   • Replace ROLE with each individual role.
9. Install the Google Cloud CLI.

10. To initialize the gcloud CLI, run the following command:

    gcloud init

11. Create or select a Google Cloud project.

    Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

    • Create a Google Cloud project:

      gcloud projects create PROJECT_ID

      Replace PROJECT_ID with a name for the Google Cloud project you are creating.

    • Select the Google Cloud project that you created:

      gcloud config set project PROJECT_ID

      Replace PROJECT_ID with your Google Cloud project name.

12. Make sure that billing is enabled for your Google Cloud project.

13. Enable the required APIs:

    gcloud services enable financialservices.googleapis.com bigquery.googleapis.com cloudkms.googleapis.com bigquerydatatransfer.googleapis.com

14. If you're using a local shell, then create local authentication credentials for your user account:

    gcloud auth application-default login

    You don't need to do this if you're using Cloud Shell.

15. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/financialservices.admin, roles/cloudkms.admin, roles/bigquery.admin

    gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE

    • Replace PROJECT_ID with your project ID.

    • Replace USER_IDENTIFIER with the identifier for your user account. For example, user:[e-mail].

    • Replace ROLE with each individual role.
These roles fulfill the following required permissions:

Grant access to the CMEK key

The API automatically creates a service account in your project. The service account needs access to the CMEK key so it can use the key to encrypt and decrypt the underlying data. Grant access to the key.

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:[e-mail]" \
  --role="roles/cloudkms.cryptoKeyEncrypterDecrypter" \
  --project="PROJECT_ID"

Create BigQuery datasets

This section describes how to create input and output BigQuery datasets, and then copy sample banking data into the input dataset.

Create an output dataset

Create a dataset to be used to send the AML pipeline outputs to.

Bash

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

PowerShell

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

Create an input dataset

Create a dataset to copy the sample banking tables into.

Bash

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

PowerShell

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

Copy the sample dataset

Note: The sample data is protected by the same allowlist that protects API enablement documented in the Before you begin section.

Sample banking data is provided as a BigQuery dataset in Google's shared dataset project. You must have access to the AML AI API for this dataset to be accessible. Key features of this dataset include the following:

• 100,000 parties
• A core time range from January 1, 2020 to January 1, 2023 and an additional 24 months of lookback data
• 300 negative and 20 positive risk cases per month
• Risk cases with the following attributes:
  • Half of the positive risk cases are for structuring activity which occurred in the two months preceding the AML_PROCESS_START event
  • The other half covers parties with the highest amount of received money in the two months preceding the AML_PROCESS_START event
  • Negative cases are randomly generated
  • A 0.1% chance for the risk case to be generated in the opposite state (for example, a random party that is positive, or a party that has structuring activity or the highest income and is reported negative)
• The AML schema is defined in the AML input data model.

1. Copy the sample banking data into the input dataset you created.

   Bash

   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"
     }'
   

   PowerShell

   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. Monitor the data transfer job.

   Bash

   bq ls --transfer_config \
   --transfer_location=LOCATION \
   --project_id=PROJECT_ID \
   --filter="dataSourceIds:cross_region_copy"
   

   PowerShell

   bq ls --transfer_config `
   --transfer_location=LOCATION `
   --project_id=PROJECT_ID `
   --filter="dataSourceIds:cross_region_copy"
   

   After the transfer completes, a data transfer job with the display name Copy the AML sample dataset is created.

   You can also check the status of the transfer using the Google Cloud console.

   You should see something like the following output.

                        name                           displayName         dataSourceId       state
   -------------------------------------------  -----------------------  -----------------  ---------
   projects/294024168771/locations/us-central1  Copy AML sample dataset  cross_region_copy  SUCCEEDED
   

Grant access to the BigQuery datasets

The API automatically creates a service account in your project. The service account needs access to the BigQuery input and output datasets.

1. Grant read access to the input dataset and its tables.

   Bash

   bq query --project_id=PROJECT_ID --use_legacy_sql=false \
     'GRANT `roles/bigquery.dataViewer` ON SCHEMA `PROJECT_ID.my_bq_input_dataset` TO "serviceAccount:[e-mail]"'
   

   PowerShell

   bq query --project_id=PROJECT_ID --use_legacy_sql=false "GRANT ``roles/bigquery.dataViewer`` ON SCHEMA ``PROJECT_ID.my_bq_input_dataset`` TO 'serviceAccount:[e-mail]'"
   

2. Grant write access to the output dataset.

   Bash

   bq query --project_id=PROJECT_ID --use_legacy_sql=false \
     'GRANT `roles/bigquery.dataEditor` ON SCHEMA `PROJECT_ID.my_bq_output_dataset` TO "serviceAccount:[e-mail]"'
   

   PowerShell

   bq query --project_id=PROJECT_ID --use_legacy_sql=false "GRANT ``roles/bigquery.dataEditor`` ON SCHEMA ``PROJECT_ID.my_bq_output_dataset`` TO 'serviceAccount:[e-mail]'"

Create an engine config

Create an AML AI engine config to automatically tune hyperparameters based on a given engine version and the data provided. Engine versions are released periodically and correspond to different model logic (for example, targeting a retail line of business versus a commercial one).

To create an engine config, use the projects.locations.instances.engineConfigs.create method.

This stage involves hyperparameter tuning which can take some time to process. Provided your data does not change substantially, this step can be used to create and test many models.

Once the operation has completed, do the following:

1. Open BigQuery in the Google Cloud console.

   Go to the Google Cloud console

2. In the Explorer pane, find and expand your project.

3. Expand my_bq_output_dataset and click my_backtest_results_metadata.

4. On the menu bar, click Preview.

5. In the name column, find the row with ObservedRecallValues.

   

6. Assume that your capacity for investigations is 120 per month. Find the recall value object with "partyInvestigationsPerPeriod": "120"`. For the following sample values, if you limit investigations to parties with risk scores greater than 0.53, then you can expect to investigate 120 new parties each month. Over the backtesting period, the year 2022, you would identify 86% of cases that the previous system identified (and possibly others, which were not identified by your current processes).

   {
     "recallValues": [
       ...
       {
         "partyInvestigationsPerPeriod": "105",
         "recallValue": 0.8142077,
         "scoreThreshold": 0.6071321
       },
       {
         "partyInvestigationsPerPeriod": "120",
         "recallValue": 0.863388,
         "scoreThreshold": 0.5339603
       },
       {
         "partyInvestigationsPerPeriod": "135",
         "recallValue": 0.89071035,
         "scoreThreshold": 0.4739899
       },
       ...
     ]
   }
   

See more about the other fields in the backtest results.

By changing the partyInvestigationsPerPeriodHint field, you can modify the number of investigations a backtest produces. To obtain scores to investigate, register parties and produce predictions against them.

Import registered parties

Before creating prediction results, you need to import registered parties (that is, customers in the dataset).

To import registered parties, use the projects.locations.instances.importRegisteredParties method.

Request JSON body:

Keep checking for the result of that operation until it completes. When it completes, you should see that 10,000 parties were registered in the JSON output.

Create a prediction result

Create a prediction result on the last 12 months in the dataset; these months were not used during training. Creating prediction results creates scores for each party in each month across all the prediction periods.

To create a prediction result, use the projects.locations.instances.predictionResults.create method.

Analyze a single structuring case in the Google Cloud console

Note: Due to differences in engine versions and the evolution of synthetic data over time, these results may not exactly match your outputs.

1. Open BigQuery in the Google Cloud console.

   Go to the Google Cloud console

2. In the details pane, click the Untitled Query tab to see the editor.

3. Copy the following SQL statement into the editor and click Run.

   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
   

   This statement checks account ID 1E60OAUNKP84WDKB in August 2022. This account is linked to party ID EGS4NJD38JZ8NTL8. You can find the party ID for a given account ID by using the AccountPartyLink table.

   The transaction data shows frequent round transactions targeted at a single account shortly after large cash deposits, which looks suspicious. These transactions could be indicative of smurfing (that is, breaking up a large transaction of money into smaller transaction amounts) or structuring.

   

4. Copy the following SQL statement into the editor and click Run.

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

   This statement shows that there was a risk case leading to the exit of this party. The risk case started two months after the suspicious activity.

   

5. Copy the following SQL statement into the editor and click Run.

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

   By checking the prediction results, you can see that the party's risk score jumps from nearly zero (note the exponent value) to high values in the months following the suspicious activity. Your results may vary from the results shown.

   

   The risk score is not a probability. A risk score should always be evaluated relative to other risk scores. For example, a seemly small value can be considered positive in cases where the other risk scores are lower.

   Note: Due to differences in engine versions and the evolution of synthetic data over time, the results obtained may differ from these screenshots. Model results shouldn't be interpreted as a probability of money laundering; model results should be interpreted relative to the same customer over time and to other customers. The numbers obtained for explainability and risk score may differ.

6. Copy the following SQL statement into the editor and click Run.

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

   By checking the explainability results, you can see that the correct feature families score the highest values.
