Use Cases

Real-time Anonymisation for AI Products

Agencies integrate Cloak via API into chatbot services and WOG AI platforms to strip PII from user prompts in real-time before they reach external LLMs. 

Bulk Anonymisation for Policy Analysis and LLM training

The healthcare and social sectors use Cloak to anonymise large volumes of sensitive data (clinical notes, citizen correspondences, case files) for policy research, model fine-tuning, and inter-agency analysis. 

Data Sharing and Fusion across Agencies

Multiple data owners across sectors anonymise their datasets independently using shared encryption secrets, producing data that can still be linked on a common encrypted identifier for cross-agency data lakes.

Daily Operations and Dashboarding

Agencies anonymise operational data so dashboards, reports, and daily workflows do not expose PII to unauthorised staff.
