# Enable Masked Content Distributions

With the 20R1 release, Veeva Safety introduces masked distributions for study and patient content protection. This feature allows Admins and Distribution Managers to generate _Distributions_ and ICSRs that selectively mask sensitive patient or blinded study data, while continuing to generate unmasked _Submissions_ for regulatory agencies. This feature works with the _Transmission_ and _Reporting Family_ objects.

Once you enable this feature, <a href="/en/gr/01422/">configurable field masking</a>
 allows you to mask or unmask certain fields in masked distributions.

The following pages also describe how to use masked distributions:

* <a href="/en/gr/01225/">Generate Masked Safety Reports</a>
 provides information about how masked distributions work and which fields are masked.
* <a href="/en/gr/01254/">Set Up Partner Distribution Lists</a>
 provides information for administrators on how to set up reporting rules that automatically generate masked distributions.
* <a href="/en/gr/1022564/">Create an ICSR Transmission</a>
 provides information for _Distribution Manager_ users on how to manually create masked distributions.

### 25R3 Update: Patient Content Protection: Mask PII (EU Guidance)

With the 25R3 release, Vault updates Personally Identifiable Information (PII) masking to meet the requirements of the EU GVP Module VI Addendum. This feature adds the _Mask PII (EU Guidance)_ option to the _Patient Content Protection_ field on _Submissions_ which impacts masking on E2B files. On your custom reporting rule sets, you can [configure new options][1] on the <a href="/en/gr/01250/#mask-pii">_Mask PII_ reporting rule parameter</a>
 to define how Vault masks PII.
