# Redaction (data masking)

### Overview

ComplyCube automatically applies **field-level redaction** (also known as **field masking** or **data masking**) on sensitive data fields to ensure compliance with global privacy regulations.

Examples of redacted fields include:

* **Dutch BSN** (Burgerservicenummer or Dutch Citizen Service Number)
* **Singapore NRIC** (National Registration Identity Card Number)
* **Korean RRN** (Resident Registration Number)

{% hint style="info" %}
To meet strict compliance requirements, sensitive fields are automatically redacted from **document images** stored in the customer record and the results of **Document Checks**. Where applicable, redaction is applied to both the **front and back** of the document.
{% endhint %}

{% hint style="info" %}
Users on our **Growth** or **Enterprise** **plans** can customize and add additional fields to their [redaction policies](https://portal.complycube.com/policies). Please contact your Account Manager to update your policy.
{% endhint %}

### Scope

Redaction is applied immediately on document capture, before the document image is stored. All instances of sensitive fields are masked, including those encoded within **QR codes**, the **Visual Inspection Zone (VIZ)**, the **Machine Readable Zone (MRZ)**, and **barcodes**.

ComplyCube does not **store** or **process** these sensitive fields, ensuring strong privacy protection and full regulatory compliance.

During **Document Check** processing, all redacted text fields return as fixed-length asterisk (\*) strings. This format is consistent across the **API**, **Web Portal**, and **reports**.

### Where redaction is applied

Redaction applies anywhere ComplyCube displays or returns document images or extracted fields, including:

* Stored document images in the customer record (Portal and exports).
* [Document Check](https://docs.complycube.com/documentation/product-guides/identity-verification/document-check) results returned via API and visible in the Portal.
* Generated reports that include document images or extracted fields.

### Configuring redaction policies

Redaction is enabled by default for supported sensitive fields.

If you need to modify or add masking rules, your redaction configuration can be updated by contacting your Account Manager.
