  • Publication number: 20240037274
    Abstract: Techniques for storing health data can include a multi-node data structure. A data node, a category node, and an institution node of a multi-node data structure can be generated in accordance with a configuration file. The data node can include health data and can be identified by a first unique data identifier and encrypted using a first cryptographic key. The category node can include the first unique data identifier and the first cryptographic key. The category node can be identified by a second unique data identifier and encrypted using a second cryptographic key. The institution node can include the second unique data identifier and the second cryptographic key. The institution node can be identified by a third unique data identifier and encrypted using a third cryptographic key. The data node, the category node, and the institution node can be shared with a service provider.
