The usage of digital and intelligent healthcare applications on mobile devices has grown progressively. These applications are generally distributed and access remote healthcare services on the user's applications from different hospital sources. These applications are designed based on client-server architecture and different paradigms such as socket, remote procedure call, and remote method invocation (RMI). However, these existing paradigms do not offer a security mechanism for healthcare applications in distributed mobile-fog-cloud networks. This paper devises a blockchain-socket-RMI-based framework for fine-grained healthcare applications in the mobile-fog-cloud network. This study introduces a new open healthcare framework for applied research purposes and has blockchain-socket-RMI abstraction level classes for healthcare applications. The goal is to meet the security and deadline requirements of fine-grained healthcare tasks and minimize execution and data validation costs during processing applications in the system. This study introduces a partial proof of validation (PPoV) scheme that converts the workload into the hash and validates it among mobile, fog, and cloud nodes during offloading, execution, and storing data in the secure form. Simulation discussions illustrate that the proposed blockchain-socket-RMI minimizes the processing and blockchain costs and meets the security and deadline requirements of fine-grained healthcare tasks of applications as compared to existing frameworks in work.
移动设备上的数字和智能医疗应用的使用已经逐渐普及。这些应用程序通常基于客户端-服务器架构和不同的范例（如套接字、远程过程调用和远程方法调用（RMI））设计，从不同医院的来源为用户的应用程序分配和访问远程医疗服务。然而，这些现有的范例并没有为分布式移动雾云网络中的医疗应用程序提供安全机制。本文为移动雾云网络中的细粒度医疗应用程序设计了一个基于区块链-套接字-RMI 的框架。本研究引入了一个新的开放医疗保健框架，用于应用研究目的，并为医疗应用程序引入了区块链-套接字-RMI 抽象级别类。目标是满足细粒度医疗任务的安全性和截止日期要求，并在系统中处理应用程序时最小化执行和数据验证成本。本研究引入了一种部分验证证明（PPoV）方案，该方案将工作负载转换为哈希值，并在移动、雾和云节点之间进行验证，以在安全形式下卸载、执行和存储数据。仿真讨论表明，与现有工作中的框架相比，所提出的基于区块链-套接字-RMI 的框架可以最小化处理和区块链成本，并满足应用程序的细粒度医疗任务的安全性和截止日期要求。
