The SEOS (Smart Eye Operating System) team aims to leverage core blockchain technologies to establish a public chain for comprehensive health and medical data. Relying on blockchain technology, it integrates data sharing across interconnected devices and systems, securely consolidating and managing medical data generated by various devices, including smartphones, as well as data scattered across different healthcare institutions. This approach facilitates the return of ownership and management rights of medical data to users; establishes personalized health records; and develops secure, compliant, controllable, and scalable health applications. It supports the development of precision medicine models and promotes the implementation of AI diagnostic technologies, thereby building a healthy and trustworthy blockchain ecosystem in healthcare to provide better services to a wide range of users.
