Train and test models designed to detect money laundering

Learn how to do basic operations in Anti Money Laundering AI by using command-line tools on your development machine or in the Google Cloud console.

In this guide, you provide sample bank transaction data in the form of BigQuery tables as input to AML AI. The API outputs BigQuery tables that include backtest results and prediction results. The results are used to analyze an example party that is laundering money by structuring funds.

Before you begin

  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.

    • 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. Create local authentication credentials for your Google Account:

    gcloud auth application-default login
  8. Grant roles to your Google Account. Run the following command once for each of the following IAM roles: roles/financialservices.admin

    gcloud projects add-iam-policy-binding PROJECT_ID --member="user:EMAIL_ADDRESS" --role=ROLE
    • Replace PROJECT_ID with your project ID.
    • Replace EMAIL_ADDRESS with your email address.
    • 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.

    • 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. Create local authentication credentials for your Google Account:

    • Replace PROJECT_ID with your project ID.
    • Replace EMAIL_ADDRESS with your email address.
    • Replace ROLE with each individual role.
  16. The API requests in this guide use the same Google Cloud project and location and hard-coded resource IDs to make the guide easier to complete. The resource IDs follow the pattern my-resource-type (for example, my-key-ring and my-model).

    Make sure the following replacements are defined for this guide:

    • PROJECT_ID: your Google Cloud project ID listed in the IAM Settings
    • PROJECT_NUMBER: the project number associated with PROJECT_ID. You can find the project number on the IAM Settings page.
    • LOCATION: the location of the API resources; use one of the supported regions:
      • us-central1

    "kmsKey": "projects/KMS_PROJECT_ID/locations/LOCATION/keyRings/my-key-ring/cryptoKeys/my-key",
    "state": "ACTIVE"
  }
}

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:service-PROJECT_NUMBER@gcp-sa-financialservices.iam.gserviceaccount.com" \
  --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

Run the following command to create a dataset to be used to send the AML pipeline outputs to.

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

Create an input dataset

Run the following command to create a dataset to copy the sample banking tables into.

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

Copy the sample dataset

Sample banking data is provided as a BigQuery public dataset. 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)
  1. Run the following command to copy the sample banking data into the input dataset you created.

    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. Open BigQuery in the Google Cloud console.

    Go to the Google Cloud console

  3. Find and expand the input dataset in the Explorer pane. After a few minutes, you should see tables in the input dataset. You can also check the status of the transfer by selecting Data transfers from the BigQuery navigation menu. The AML schema is defined in the AML input data model.

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. Install jq on your development machine. If you cannot install jq on your development machine, you can use Cloud Shell or one of the other methods for granting access to a resource found in the BigQuery documentation.
  2. Run the following commands to grant read access to the input dataset and its tables.
# 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

Run the following commands to grant write access to the output dataset.

# 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"

  4. Find the row with the name ObservedRecallValues.

    Observed recall values in BigQuery.

  5. 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 the old system).

Analyze a single structuring case in the Google Cloud console

  1. Open BigQuery in the Google Cloud console. Make sure SQL workspace is selected.

    Go to the Google Cloud console

  2. The BigQuery page has three main sections:

    • The BigQuery navigation menu
    • The Explorer pane
    • The details pane

    In the details pane, click Compose a New Query to open the query editor.

    Compose a new query.

  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. The transaction data shows a series of round transactions targeted at a single account, which looks suspicious.

    Suspicious transaction data for a single party.

  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.

    Risk case events for a single party.

  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 to high values in the months following the suspicious activity.

    Risk scores increasing for a single party.

  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.

    Explainability results for predictions.
