Operated from EU territory by an EU citizen under Greek jurisdiction, ensuring data never leaves the EU. Fully compliant with GDPR Article 44 for maximum data sovereignty.
An ARIA Node Operator is a licensed entity authorised to operate an ARIA Capsule node within a specific regulatory jurisdiction, subject to the terms and technical specifications of Sovereign Governance Systems Ltd. The ARIA EU Node operated via bioinformatics.gr is fully sovereign: all data processing occurs within EU borders, under the direct oversight of an EU citizen, and in accordance with applicable EU law.
Dr Triantafyllos Paparountas — Greek citizen and bioinformatics/AI governance specialist — serves as the EU Node Operator. This arrangement ensures that data controller responsibilities, technical custody, and operational decision-making all reside within EU jurisdiction, with no reliance on third-country infrastructure for processing activities covered under GDPR Chapter V.
The EU Node does not transfer, replicate, or proxy personal data or regulated research data outside the EU/EEA without explicit data subject consent and a valid transfer mechanism as defined under GDPR Article 44.
Operated under Greek law (HDPA oversight), an EU member state, ensuring full GDPR applicability and institutional accountability.
The node operator holds Greek citizenship, satisfying CADA Level 3 requirements for EU data sovereignty certification.
All processing activities are confined to EU/EEA infrastructure. No data residency exceptions are made without documented legal basis.
This node operates exclusively within EU/EEA territory, eliminating the need for Chapter V transfer mechanisms. All processing activities meet the adequacy standard by design, not by derogation.
The ARIA Capsule architecture is designed to satisfy EU AI Act obligations for high-risk AI systems, including conformity assessment, technical documentation, and post-market monitoring requirements applicable to AI systems in life sciences.
CADA (Certified AI Data Architecture) Level 3 requires both EU legal entity ownership and EU citizenship for the responsible operator. This node meets both requirements: SGS Ltd is UK-registered with EU citizen ownership and operational control.
The ARIA Capsule is a patented sovereign technology (UK GB2612045.1; US Application #19/693,491) that forms the backbone of this node's infrastructure. It provides a multi-tier security architecture combining cryptographic integrity, differential privacy, and hardware attestation — ensuring that AI workloads remain auditable, tamper-evident, and jurisdictionally confined.
This EU Node operates ARIA Capsule tiers T1 through T3 in a fully operational state, with the T4 AMD SEV-SNP hardware TEE tier planned for Q4 2026.
