Systems and methods for a multi-system, multi-client, multidirectional, cyber-resilient, permissioned blockchain imaging data exchange platform
Techniques are described herein for enhancing the privacy, confidentiality, cyber-resilience, and operational efficiency of multi-system, multi-client, multi-directional image exchanges among client users, devices, servers, cloud environments, or other applications within one network or a system of networks by deploying a permissioned blockchain, that uses threshold cryptographic primitives and the key component of permissioned blockchains called Byzantine fault-tolerant (BFT) protocol, combined with fine-grained access control, publish/subscribe capabilities and a novel use of the private chaincode functionality during image exchange operations, which involves image sharing without sacrificing performance. Techniques, methods, processes, and systems described herein can enhance operational efficiency by increasing operational processing speed and reducing operational processing time for image exchange operations within the platform.
1 . A non-transitory permissioned blockchain technology system, including:
(1) enhanced privacy, confidentiality, and security of image exchanges with off-chain image storage while all other image-related metadata are cryptography hashed and the owner's digital signature is stored onchain;
wherein the enhanced privacy, confidentiality, and security of the image exchanges are due to
(a) execution of integrity-protected private chain codes in an enclave, isolated from an operating system and hypervisor;
(b) secure channels and protection even during transit within each blockchain network;
(c) advanced identity management and fine-grained access control which allows greater complexity and control of image access;
(d) decentralized access control for zero-trust network identity protection during image exchange operations by offering publication and subscription functionality; and
(e) a permissioned blockchain that uses threshold cryptographic primitives and a Byzantine fault-tolerant (BFT) protocol, combined novel private chain code functionality for image exchange operations;
(2) enhanced and secure auditability of image exchange operations within the permissioned blockchain technology platform (a) by recording all the image exchange operations on an immutable ledger, and (b) due to data provenance functionality;
(3) enhanced operational efficiency of the image exchange operations due to the private chain code functionality and secure off-chain image storage; and
(4) a multi-trust without requiring complicated authentication processes for members already authorized within the permissioned blockchain.
2 . A method comprising:
(1) enhancing privacy, confidentially, and security of image exchanges with off-chain image storage while all other image-related metadata are cryptography hashed and the owner's digital signature is stored on chain;
wherein the enhanced privacy, confidentiality, and security of the image exchanges are due to preforming the steps of:
(a) executing integrity-protected private chain codes in an enclave, isolated from an operating system and hypervisor;
