👨‍🔧Overview

ULALO Architecture leverages AI, Blockchain, Decentralized storage, and advanced cryptographic techniques to ensure secure, private and efficient management of electronic health records.

ULALO Smart Patient system architecture centers around secure and data-privacy aware system to manage electronic health records (EHR). Here's a summary of how we use Web3 technologies:

• Identity and Blockchain:

  • Decentralized Identifiers (DID) is used for secure identity management.

  • The ULALO L1 Chain is used to keep blockchain state and to manage transactions at very low fees.

• Document Handling and Storage:

  • Patients can scan documents from their phones and stored them as PDFs.

  • Encrypted PDFs are stored on the InterPlanetary File System (IPFS).

  • The Hash of the PDF is stored on the Blockchain for data integrity.

• AI Integration:

  • OCR libraries are used to extract key information from EHR data like for classification and making them easy to retrieve to the patient.

• Data Security and Privacy:

  • EHR data is encrypted with the patient's key.

  • Access control lists(ACL) are used to share data with providers that the patient choose to.

  • Patient data is queried using Zero-Knowledge (ZK) proofs to preserve privacy.

  • Hashes and previous hashes are used to maintain data integrity.
