Handling Sensitive Information

Your data sets might contain sensitive information that you want to handle carefully. Credit card numbers, social security numbers, and other personal details like birthdates in data files are considered sensitive information. You can partially or completely obfuscate such values so that you can process it without placing any personal or identifying information at risk. An alert icon is displayed next to columns that the system identifies as sensitive information.

Always look at the alerts and recommendations before obfuscating data manually. The recommendations pane offers different options, including partial obfuscation and the removal of sensitive data records. For more information on alerts, see Viewing and Fixing Alerts. For more information on recommendations, see Viewing and Applying Recommendations.

To handle sensitive information:

1. On the main authoring page, identify the transform column that contains sensitive information.
2. In the Column cell, click the More Actions icon.
   A drop-down list appears.
3. Select Obfuscate.

The transform script now contains an action to obfuscate the selected sensitive column. When you run the transform on a data set, the data for the selected column is obfuscated.
