Abstract: 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.
