Privacera Platform

Create and run Databricks UDF for masking
:

You can create Privacera user-defined functions (UDFs) for masking by running the following SQL query in your Databricks cluster:

drop function if exists db.mask;
CREATE FUNCTION db.mask AS 'com.privacera.crypto.PrivaceraMaskUDF'
Run sample queries to verify masking and encryption

Redact the column email from the customer_data database with the masking scheme EMAIL_REDACT_SCHEME and save the output to a column called RedactedEmail.

select mask(email,'EMAIL_REDACT_SCHEME')
as RedactedEmail
db.customer_data;

Single query to encrypt and mask: Encrypt (protect) the column PERSON_NAM from the customer_data database with the PERSON_NAME_ENCRYPTION_SCHEME and mask the EMAIL from the customer_data database with the masking scheme EMAIL_MASKING_SCHEME. The data are transformed in place with no intermediate location.

select protect(PERSON_NAME,'PERSON_NAME_ENCRYPTION_SCHEME'),
mask(EMAIL,'EMAIL_MASKING_SCHEME')
from db.customer_data;
