'STEWART' - Building a Symbiotically Secure Lowcost Healthcare Platform

Development of an innovative, secure platform for optimizing patient care with an integrated ECG wristwatch for long-term monitoring and symbiotic zero-knowledge security.

The Symbiotically Secure Lowcost Healthcare Platform project represents a groundbreaking initiative to revolutionise healthcare technology through the development of innovative, highly-secure, and cost-effective digital medical solutions. This ambitious project addresses the critical need for affordable yet secure healthcare infrastructure in an increasingly digital world.

Project Objectives

Our primary objective is to create a comprehensive healthcare platform that seamlessly integrates security at every level while maintaining affordability for healthcare providers of all sizes. The project aims to:

  • Develop a symbiotic security architecture that provides multi-layered protection without compromising performance
  • Create cost-effective solutions that make advanced healthcare technology accessible to smaller medical facilities
  • Implement cutting-edge cryptographic protocols specifically designed for medical data protection
  • Establish new standards for secure medical device communication and data exchange
  • Ensure compliance with international healthcare data protection regulations

Key Innovation Areas

Our research focuses on developing novel approaches to healthcare security that go beyond traditional methods, incorporating symbiotic security principles where multiple security layers work together to enhance overall protection while reducing individual component costs.

Technical Approach and Methodology

This application study focuses on developing a secure ECG wristwatch based on an eWatch platform for privacy-compliant remote patient monitoring, particularly 24-hour outpatient ECG data collection. The project involves multiple partners across Germany and Turkey, with WIZnet leading as a data protection and security expert, Medron handling device development with Demsay's collaboration, as well as security analysis and modelling support by the University of Stuttgart.

eHealth Watch System Architecture

The wristwatch will feature a symbiotically secure architecture SoC, low-power high-precision sensors, and comprehensive security measures to protect patient data integrity and privacy. Beyond technical development, the project includes creating training programs for medical staff and patients, conducting extensive testing for device durability and reliability, and performing detailed analysis of data transmission, performance metrics, and security protocols to optimise the system's overall effectiveness and battery life.

Expected Impact and Benefits

The successful completion of this project will have far-reaching implications for the healthcare industry and the wider European footing in advanced IoT security manufacturing:

  • Democratisation of Secure Healthcare Technology: Making advanced security accessible to smaller clinics and healthcare providers
  • Enhanced Patient Data Protection: Providing unprecedented levels of security for sensitive medical information, unlocking previously unavailable healthcare functionality due to safety concerns
  • Reduced Healthcare Costs: Lowering the financial barrier to implementing secure digital health solutions
  • Improved Interoperability: Creating standards that enable secure communication between diverse healthcare systems
  • Innovation in Medical Security: Establishing new paradigms for healthcare cybersecurity, positioning Europeans SMEs as industry leaders in secure eHealth
