What is the health index?
Think of a health history as a book whose chapters are kept in different libraries. The index does not copy the chapters: it keeps the map used to find them with permission.
Link, do not copy
Keep links to reports, tests and other records that remain at their source.
Control access
Authorise what can be shared and with whom. Each access can be recorded.
Use one card
Show the QR code to find the index during an emergency or continued care.
Long-term confidentiality
Protection designed for data that may remain sensitive for decades
Confidential storage with post-quantum protection for encryption keys. Each document is encrypted with AES and its key is protected for the recipient using NIST-standardized ML-KEM.
This reduces the risk that someone steals encrypted information today, keeps it, and later tries to decrypt it using quantum computers.
Your PIN unlocks the protected profile. The service also protects profile keys independently, and every document uses its own encryption key. Knowing the login or possessing only the stored data is not enough to open it.
The protection is designed for information that may need to remain confidential for 10, 50, or 100 years. No responsible system can promise that encryption will remain impossible to break for that entire period; UNID uses standardized algorithms, key separation, versioning, and rotation so protection can evolve.
How It Works
Three simple steps
Create the card
Add a nickname and the necessary personal details. UNID is the default service.
Give permission
Authorise health organisations to link information in the index.
