The organization could further strengthen its privacy controls by deploying Differential Identifiability. Differential identifiability is a privacy-enhancing technique that allows the organization to use and share aggregate information about user data, while minimizing the risk of identifying individual users. This is particularly important in the context of medical data, which can be sensitive and personal. It’s worth noting that while the other options may have their own benefits in certain contexts, they do not directly address privacy concerns in the same way as differential identifiability.
