Focused on the development of an interoperable registration system for medical records, OSASUKAT: blokchain platform project, has concluded after two years of collaboration between different research centers and other entities. The project has consisted in the development of a solution able to make easier the integration of patients’ medical record information provided by different sources and centers. To this aim, BioKeralty has established the functional requirements, designed the architecture of the global system and participated in the evaluation of the operational performance of the tools developed.

Data availability, confidentiality, integrity and non-repudiation key aspects to guarantee project security

The OSASUKAT project results allowed to complete the implementation and integration of different the modules included in the OSASUKAT general architecture system and to implement a testing environment to validate the functional and operational requirements of the platform. To this aim, the integration of relevant medical data of people with breast cancer was taken as starting point. The goals achieved were:

• 1. Conclude the implementation of the system services module: this module allows healthcare personnel to look up patients’ health information and services to configure and manage the whole platform.
• 2. Complete the blockchain module: this module is useful to implement those functionalities that are required to guarantee data security and information access. To make this possible, patients’ medical history access traceability and data treatment has been implemented. In addition, it includes a blockchain technology security layer.
• 3. Complete the development of different interoperability connectors: connectors allow to retrieve medical data from an EHR (Electronic Health Record) located in repositories with different HIS (Health Information System) systems.
