Have you ever wondered where all the health data generated from annual check-ups ultimately ends up? Companies claim "anonymization," but industry insiders know that these data chains are actually quite fragile. The risk of privacy leaks is like a sword hanging overhead, ready to fall at any moment.

A more pressing issue is that your health information should be your own asset, yet it’s locked away in various medical institutions’ databases. It can neither provide a coherent reference for your subsequent diagnosis and treatment nor contribute to medical research while effectively protecting your privacy. This "both unusable and immovable" state is indeed quite awkward.

The root of the problem lies in the lack of a collaborative mechanism that can both protect privacy and be verified. But recently, I’ve discovered that with technologies like zero-knowledge proofs and programmable privacy, there might be a solution.

Imagine this scenario: your genomic data, chronic disease history, medical images—all under your control. Through privacy-preserving computation networks, this highly sensitive information can be transformed into encrypted, verifiable credentials. When you need to share information with a new hospital or research institution, you don’t have to expose the raw data; you just generate a cryptographic proof—such as "my indicator is within the normal range" or "I have completed a specific vaccination." The other party can verify the authenticity of the information without seeing any additional details.

What does this change bring? Cross-institutional and cross-regional collaborative diagnosis and medical research can now be conducted without ever touching the original data. Privacy is no longer a stumbling block—instead, it becomes the cornerstone for driving medical innovation.
