A new paradigm in healthcare data privacy and security

Today’s health IT landscape is a constellation of isolated, locally hosted repositories taking on costs and risks of data protection, while patients remain disenfranchised, without an actual understanding or control over the use of their personal information. MyHealthMyData (MHMD) aims at fundamentally changing these assumptions by introducing a new way to share private information and empower their primary owners, the patients. MHMD will foster the development of a true information marketplace, enabling individuals to exercise full control over their personal data and leverage their value, implementing new mechanisms of trust and direct, value-based relationships between EU citizens, hospitals, research centres and businesses.

Key elements of this innovation, implemented through this new model, include:


A shared public data ledger where information is boiled down into hash language-based codes, which everyone can inspect but no single user controls. This system is used to distribute control of fraudulent activities to the entire network of stakeholders, as any attempt to tamper with whichever part of the blockchain is immediately evident and easily detectable.

Dynamic Consent

The possibility for individuals to provide different types of consent according to distinct potential data uses, taking control over who will access his/her data and for what purpose.

Personal Data Accounts

Personal data storage clouds enabling individual access from any personal device through the blockchain in a probative, secure, open and decentralized manner.

Smart Contracts

Self-executing contractual states, based on the formalisation of contractual relations in digital form, which are stored on the blockchain and automate the execution of peer-to-peer transactions under user-defined conditions.

Multilevel De-identification and Encryption Technologies

Advanced techniques for encoding and de-associating sensible data from the owners’ identity (i.e. multi-party secure computation, homomorphic encryptions), while allowing analytics applications to leverage the information.
