DPPH Key Enablers
The envisioned platform for DPPH relies on cutting-edge cryptographic technology and open-source frameworks to provide a usable, flexible and easily maintainable system that can be seamlessly deployed at hospitals and enable efficient and scalable data sharing and processing across clinical data warehouses in a privacy-conscious way, and enforcing the privacy policies of each hospital. These are the sought properties and enablers leveraged to achieve them in DPPH:
Privacy-conscious sensitive data processing
Accessibility and Usability
Scalability and Elasticity
Data Traceability and Management
Security and Accountability
The DPPH architecture enables efficient and scalable privacy-conscious data sharing across a federation of hospitals, comprising all steps from the encrypted ETL (Extract, Transform, Load) at the hospitals, to the sharing and processing of the encrypted and protected data in the federation. The figure below depicts an example instantiation integrating i2b2 and SHRINE.
