The Internet of Medical Things (IoMT) is the next frontier in the digital revolution and it leverages IoT in the healthcare domain. The underlying technology has changed the current healthcare system by collecting real-time data of patients and providing a patient motioning system. But IoMT also presents a big challenge for data storage management, security, and privacy due to cloud-based storage. Today, this large volume of IoMT generated medical data is stored in the centralized storage system. However, centralization of patient sensitive information leads to a single point of failure, privacy, and security concern. To address these issues, we propose a smart contracts enabled consortium blockchain network. We integrated interplanetary file systems (IPFS) cluster node where smart contracts are deployed at the initial stage for authentication of patient’s and medical devices, the same cluster layer is also proposed as a distributed data storage layer for device-generated data after authentication and these data are securely transmitted over the consortium blockchain. The IPFS cluster node ensures the security and authentication of the devices and it also provides secure storage management in IoMT enabled healthcare system. The consortium network enables the privacy of data owing to hash-based storage in a block of IoMT enabled healthcare network.

利用区块链和IPFS技术实现医疗物联网(IoMT)安全和隐私框架的设计和实现

医疗物联网(IoMT)是数字革命的下一个前沿领域,它在医疗保健领域利用物联网。底层技术通过收集患者的实时数据并提供患者运动系统,改变了当前的医疗系统。但是由于基于云的存储,IoMT还为数据存储管理,安全性和隐私性提出了巨大挑战。今天,由IoMT生成的大量医疗数据存储在集中式存储系统中。但是,集中患者敏感信息会导致单点故障,隐私和安全问题。为了解决这些问题,我们提出了一个支持智能合约的联盟区块链网络。我们集成了星际文件系统(IPFS)群集节点,该群集节点在初始阶段就部署了智能合约以对患者和医疗设备进行身份验证,并且还建议将同一群集层作为分布式数据存储层,用于身份验证后的设备生成数据和这些数据通过财团区块链安全传输。IPFS群集节点可确保设备的安全性和身份验证,并且还可在支持IoMT的医疗保健系统中提供安全的存储管理。由于在支持IoMT的医疗保健网络中,基于哈希的存储,联盟网络实现了数据的保密性。相同的集群层也被提议为用于在认证之后用于设备生成的数据的分布式数据存储层,并且这些数据在财团区块链上安全地传输。IPFS群集节点可确保设备的安全性和身份验证,并且还可在支持IoMT的医疗保健系统中提供安全的存储管理。由于在支持IoMT的医疗保健网络中,基于哈希的存储,联盟网络实现了数据的保密性。相同的集群层也被提议为用于在认证之后用于设备生成的数据的分布式数据存储层,并且这些数据在财团区块链上安全地传输。IPFS群集节点可确保设备的安全性和身份验证,并且还可在支持IoMT的医疗保健系统中提供安全的存储管理。由于在支持IoMT的医疗保健网络中,基于哈希的存储,联盟网络实现了数据的保密性。
