Cognitive Privacy Filter
- Naveen Srinivasa
The Privacy Filter module hides sensitive information such as names, email addresses, credit card numbers, IP addresses, etc. present within various CRM system objects. You can connect your data source to this module, select the appropriate information and choose how to hide the original information. Once all the sensitive information is obfuscated, the data source will still have all the relevant context and knowledge that can be used to connect with various Ascendo products.

How do I choose the entities for the Privacy Filter module to detect and filter?
Ascendo AI’s Privacy Filter module enables you to bundle multiple entities into a single group called Presets. Each Preset contains a list of entities, how each entity is filtered (replace, mask, redact) and the values associated with the chosen filtering method.
The presets can be configured in the Ascendo AI’s Privacy Filter Module.
Testing the Preset
Once the presets are configured, you can head over to the Playground. Here, you can provide any text to the Input, select your preset and choose the Sensitivity level. The Sensitivity defines strictness of the privacy filter model when identifying an entity.
