Image Masking

Hide potentially sensitive recorded information collected by Process Discovery.

When masking is enabled, every screen capture displayed on the Console goes through the masking mechanism that:

  1. Analyzes all the text on the recorded screen

  2. Identifies potentially sensitive information

  3. Blurs out the target text

In the event that you don't want specific words masked, you can create a list of ignored terms and add them to the Codex file, an encrypted CSV file that you add to MongoDB.

For more details on the Codex file, see Codex in MongoDB.
