An IoT-Based Framework of Webvr Visualization for Medical Big Data in Connected Health

Abstract

Recently, telemedicine has been widely applied in remote diagnosis, treatment and counseling, where the Internet of Things (IoT) technology plays an important role. In the process of telemedicine, data are collected from remote medical equipment, such as CT machine and MRI machine, and then transmitted and reconstructed locally in three-dimensions. Due to the large amount of data to be transmitted in the reconstructed model and the small storage capacity, data need to be compressed progressively before transmission. On this basis, we proposed a lightweight progressive transmission algorithm based on large data visualization in telemedicine to improve transmission efficiency and achieve lossless transmission of original data. Moreover, a novel four-layer system architecture based on IoT has been introduced, including the sensing layer, analysis layer, network layer and application layer. In this way, the three-dimensional reconstructed data at the local end is compressed and transmitted to the remote end, and then visualized at the remote end to show reconstructed 3D models. Thus, it is conducive to doctors in remote real-time diagnosis and treatment, and then realize the data processing and transmission between doctors, patients and medical equipment.INDEX TERMS Internet of Thing (IoT), telemedicine, lightweight progressive transmission, medical big data, visualization.

IoMT amid COVID-19 pandemic: Application, architecture, technology, and security

“…This was developed to satisfy IoMT functional requirements using a five-layer architecture - sensing/execution layer, communication auxiliary layer, network transmission layer, data integration layer, and application service layer. Alternatively ( Xu et al., 2019 ), has introduced a four-layer system architecture based on IoT - application layer, network layer, analysis layer, and sensing layer. The objective was to improve transmission for remote diagnose and treatment that require data processing and data visualization for three-dimensional images and, at the same time, provide data transmission security.…”

“…In view of hardware constraints, lightweight security approaches like lightweight cryptography, lightweight hybrid anomaly detection, and lightweight multi-factor authentication are possible current approaches to enforce stronger authentication in IoMT systems. In particular ( Xu et al., 2019 ), proposed a secure, lightweight authentication system for WBAN. In this scheme, forward secrecy can be ensured without the use of asymmetric encryption.…”
