Access Policy transformation example

You need to make customer data available to a colleague in your bank's marketing department for customer analysis. As part of their role and the needs of their project, your colleague in the marketing department has limited access rights to customer data.

Use an Access Policy transformation to ensure that your organization complies with data privacy regulations while allowing your colleague to gain valuable insights. At run time, the transformation hides or obscures the information for which your colleague does not have access rights based on metadata and the properties that you set on the Access Policy tab.

The following table shows part of a table called BANK_CUSTOMERS, which includes contact details, birth dates, and other items of personally identifiable information:

CUSTOMER_NAME	ADDRESS	POSTAL_CODE	PROFESSION	EMAIL_ADDRESS	CUSTOMER_TYPE	DAY_OF_BIRTH
Brayden Combs	7776 Proctor Drive	48089	Associate Marketing	brayden.combs@organization.com	1	03/14/1990
Osvaldo Patton	63 Rosewood Court	64051	Project Manager	osvaldo.patton@organization.com	5	01/13/1988
Alivia Oneal	64 East Thorne Court	30043	Business Analyst	alivia.oneal@organization.com	3	06/22/1956
Skyla Weeks	7556 South Shore Drive	48045	Operations Manager	skyla.weeks@organization.com	4	10/08/1961
Justice Cobb	9136 S. Lafayette St.	60187	Financial Controller	justice.cobb@organization.com	1	02/23/1963
Braxton Kramer	7 Hill Field St.	28376	Restaurant Manager	braxton.kramer@organization.com	5	11/01/1969
Erin Ryan	20 Lakeshore Street	20706	Project Manager	erin.ryan@organization.com	2	07/23/1959

To configure the mapping, complete the following tasks:

Add a Source transformation that reads the BANK_CUSTOMERS source table.

Add an Access Policy transformation to the mapping canvas, and connect it to the data flow.

On the

Access Policy

tab, take the following actions:

In the

Consumer

field, select your marketing department colleague.

In the

Usage

field, select "customer analysis" as the usage context.

Users create and manage usage context in

Data Marketplace

. To learn more, see

Working With Data Collections

in the Data Marketplace help.

In the

Data Asset

field, select the BANK_CUSTOMERS table as the source data asset.

To use consistent tokenization, enter a consistency seed from another Access Policy transformation. Otherwise, generate a new consistency seed.

Click

Synchronize Access Policy

Add other transformations to the mapping as required.

Add a Target transformation to the mapping and connect it to the upstream transformation.

Click

Run

The

mapping

task applies the policies to the data, protecting it.

The following table shows the protected data:

CUSTOMER_NAME	POSTAL_CODE	PROFESSION	EMAIL_ADDRESS	CUSTOMER_TYPE	access_policy_filter
