Healthcare Asset Bridge System

The Decentralized Data Bridge System is designed to facilitate the secure and efficient exchange of data between data providers and data consumers. This system leverages several key components, including light Nodes, IPFS Storage Nodes, and Trusted Execution Environment (TEE) Nodes, to ensure the privacy, integrity, and security of data throughout the entire process.

Data Encryption and Storage

Data providers begin by encrypting their data to ensure its security and integrity. This encrypted data is then saved on the blockchain, creating a secure and immutable record. To further enhance data availability and redundancy, Light Nodes save the encrypted data to IPFS Storage Nodes. IPFS (InterPlanetary File System) is a decentralized file storage system that ensures data is distributed and accessible across a decentralized network.

Data Request and Approval

When a data consumer wishes to purchase data, they initiate a request. This request is forwarded by the system to the data provider, along with the data consumer's public key. The data provider reviews and approves the request, generating a proxy key as part of the approval process. This proxy key is then sent to the blockchain, ensuring it is securely recorded and accessible.

The Decentralized Data Bridge System is designed to facilitate the secure and efficient exchange of data between data providers and data consumers. This system leverages several key components, including light Nodes, IPFS Storage Nodes, and Trusted Execution Environment (TEE) Nodes, to ensure the privacy, integrity, and security of data throughout the entire process.

Secure Data Transmission

Once the data request is approved and the proxy key is generated, Light Nodes save the proxy key for subsequent use. The data consumer completes the payment process and reissues the data request. Light Nodes then load the requested data from the IPFS Storage Nodes. To ensure the data's security during transmission, TEE Nodes utilize the proxy key to re-encrypt the data. This re-encryption process ensures that the data remains secure and private as it is transmitted to the data consumer.

Data Delivery

Finally, the system delivers the re-encrypted data to the data consumer. This entire process ensures that data can flow securely and efficiently between providers and consumers, maintaining the privacy and security of the data at all stages.

The Decentralized Data Bridge System represents a robust framework for data exchange within the ecosystem. By leveraging advanced cryptographic techniques, decentralized storage solutions, and secure execution environments, the system provides a secure and efficient method for data providers and consumers to interact, ensuring the integrity and privacy of the data exchanged.
