# Real-World Applications You may be asking yourself what is the use and the value of becoming aware of these differences? Here are a few examples of unlinking in the real world. I would say, their use and value are immediately intuitively understood. For instance, * **Voting systems:** Voters remain anonymous, but their eligibility is verified. * **Healthcare:** Researchers can access data for studies, but the patient’s identity is never revealed. * **Online reviews:** A reviewer is verified but only visible as a username, preserving both trust and privacy. * **Digital identity frameworks**: Individuals share only attributes like “I am a licensed driver,” without showing their full ID. Each of these systems prioritizes unlinking over erasure, and it works. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
