Deleting user data using keys

Abstract:

Described are techniques for tracking associations between known keys and internal keys related to user data received at a natural language processing system and shared with target systems. The system can receive a request to delete data associated with a user or device, and determine one or more known keys related to the request. The system can retrieve previously stored associations between known keys and internal keys, and use the associations to generate a delete command containing relevant internal keys to be sent to the target systems, which in turn can delete data associated with the internal keys.
