AETHERIA, the platform to end the 'maze' of the medical record
Every time a patient changes hospital, their medical history starts all over again. Paper reports, stray PDFs and systems that can’t communicate make it difficult for doctors to see the full picture. AETHERIA was created to put an end to this problem.
The platform, developed by Izertis, uses advanced AI to convert any medical document, physical or digital, into the international HL7 FHIR standard, allowing the information to be unified in a format that all healthcare systems can understand. From there, citizens can store their data in a secure digital wallet and decide who to share it with, privately and verifiably.
The project also looks ahead to the Health Data Spaces, considered a cornerstone for the future of healthcare management in Europe. These collaborative environments enable the secure, regulated exchange of medical information between professionals, researchers and public systems
AETHERIA integrates with them through standard connectors based on Eclipse DataSpaces, a technology that ensures safe, traceable and interoperable data flows, a key step towards turning clinical data from an obstacle into an ally.
Key challenges in the healthcare sector
AETHERIA was created to solve one of the major bottlenecks in digital health: the fragmentation of clinical data. Today, hospitals and laboratories operate with systems that can’t understand each other and generate fragmented records in countless formats (PDF, Word, DICOM or proprietary databases) making true interoperability nearly impossible and leaving patients without real control over their information.
The consequences are well known: duplicate tests, less accurate diagnoses and soaring coasts because one doctor cannot see what has already been done in another centre. Moreover, this lack of coordination hampers the potential for biomedical research and population-based analyses that could uncover patterns key to new therapies.
AETHERIA addresses the fragmentation of clinical data by enabling secure access, interoperability, and patient sovereignty
Although European legislation (EHDS, GDPR, Data Act, eIDAS 2.0) is making progress in recognising the full right of patients to access and control their medical information, obstacles to consolidating complete records remain a daily reality.
AETHERIA changes the game by using AI to automatically convert all that clinical information to the HL7 FHIR standard, integrating self-sovereign verifiable credentials and deploying connectors for Data Spaces.
The result: secure access, total interoperability and patient sovereignty, in full alignment with European guidelines.
Four technological pillars
AETHERIA is structured around four modules that combine sovereign digital identity and artificial intelligence to transform clinical data management.
The first module integrates SSI management through the Identfy ecosystem developed by Izertis, providing an enterprise wallet for hospitals and a citizen wallet for patients, ensuring that each user maintains full control of their information.
AETHERIA integrates sovereign digital identity, AI, and semantic analysis
The second applies Deep Learning models and multimodal LLMs to automatically convert any clinical data to the HL7 FHIR standard.
It also adds an advanced semantic analysis layer capable of reviewing extensive medical records, detecting patterns, creating clinical summaries and generating predictions that support more accurate medical decisions.
The exploitation platform completes the system with a hybrid architecture that ensures interoperability, scalability and maximum security: a central infrastructure at Izertis for core services and a distributed environment, SaaS or On-Premise, with specific portals for hospitals and professionals.
This integration allows common flows such as sharing verifiable medical records between centres, granting access for diagnosis, or providing anonymised data to research projects, always under a human centric approach and with full patient sovereignty.
Significant progress
As of February 2026, AETHERIA has achieved milestones that demonstrate its technical maturity: the HL7 FHIR conversion service is already running in production, powered by Claude LLM via AWS Bedrock, and the credential flows have been validated end to end.
A concrete example: a patient can receive credentials issued by one hospital, store them in their wallet and present them to another facility for immediate care.
AETHERIA already converts data into HL7 FHIR and enables patients to use clinical credentials immediately and securely
Meanwhile, the testing infrastructure reproduces real scenarios through three EDC connectors developed by TECNALIA, linking hospitals (as both service consumers and data providers) with Izertis as producer and consumer node. These connectors already allow the HL7 FHIR service to be adapted for integration into Data Spaces.
At the same time, negotiations are progressing to incorporate the project into an operational Health Data Space, a key step to validate interoperability in a real environment.
The project’s next milestones focus on gathering real medical data to complete validation, accelerating deployment in fully functional Data Spaces, designing an intuitive user interface, and launching the AI agent, an intelligent assistant that citizens can interact with directly.
Izertis leads European digital health
Funded by the Ministry for Digital Transformation and the Civil Service, through the Recovery, Transformation and Resilience Plan and by the European Union - Next Generation EU, under the 2024 call for grants for data space technology products and services (with a total budget of €894,434 and a completion date of June 2026), AETHERIA positions Izertis as a benchmark in AI services for European healthcare. The project is developed in collaboration with TECNALIA as a subcontracted partner, drawing on its experience in over 30 R&D&I projects.
The project aims to reduce diagnostic duplication, accelerate biomedical research and give citizens full sovereignty over their clinical data, contributing directly to the European Health Data Space (EHDS).
