Development of a 3G Authentication Based Mobile Access of Health Records: A Mobile Telemedicine Application

As our country progresses in its aim to be a developed country by the Year 2020, the field of Information and Communications Technology or ICT is fast becoming the forerunner for the vision. The Internet is used in almost all aspects of life. As for the communications sector, according to Global Mobile Subscriber Database December 2002 report, there are 8,814,700 mobile subscribers in Malaysia with an Annual Growth of 16.6%. Withthe adoption of 3G-communication technology in the coming years, compelling high speed services, reaching up to 2 Mb/s together with improved security features would soon be possible. Through these years in the mobile industry, the health sector has always been neglected. Reason being, the technology could not support the application and it is not so much of a revenue generating business compared to mobile games or sports news. With globalization where the society is always on the move across borders, together with degrading environment conditions and the need for time, instant health services are becoming crucial. Looking into these conditions of mobile adoption and health status, the author intends to develop a solution for a mobile telemedicine application. Kevin Hung (2003) defines telemedicine as the utilization of telecommunication technology for medical diagnosis, treatment and patient care. Thus, the main aim of this project was to develop an application that could be used for medical purposes. This project integrates the latest mobile telecommunication technologies together with medical services with the idea of providing a highly secured personalize medical system and database query as mobile handsets are becoming a necessity to individuals. This would make updating and retrieving medical health records hassle free, anytime and anywhere. This project has also laid the groundwork for future expansion by incorporating the basic audio and video streaming features. This report accounts for all the concepts, design works and results of the mobile telemedicine application that has been developed successfully

Fog Computing in Medical Internet-of-Things: Architecture, Implementation, and Applications

In the era when the market segment of Internet of Things (IoT) tops the chart in various business reports, it is apparently envisioned that the field of medicine expects to gain a large benefit from the explosion of wearables and internet-connected sensors that surround us to acquire and communicate unprecedented data on symptoms, medication, food intake, and daily-life activities impacting one's health and wellness. However, IoT-driven healthcare would have to overcome many barriers, such as: 1) There is an increasing demand for data storage on cloud servers where the analysis of the medical big data becomes increasingly complex, 2) The data, when communicated, are vulnerable to security and privacy issues, 3) The communication of the continuously collected data is not only costly but also energy hungry, 4) Operating and maintaining the sensors directly from the cloud servers are non-trial tasks. This book chapter defined Fog Computing in the context of medical IoT. Conceptually, Fog Computing is a service-oriented intermediate layer in IoT, providing the interfaces between the sensors and cloud servers for facilitating connectivity, data transfer, and queryable local database. The centerpiece of Fog computing is a low-power, intelligent, wireless, embedded computing node that carries out signal conditioning and data analytics on raw data collected from wearables or other medical sensors and offers efficient means to serve telehealth interventions. We implemented and tested an fog computing system using the Intel Edison and Raspberry Pi that allows acquisition, computing, storage and communication of the various medical data such as pathological speech data of individuals with speech disorders, Phonocardiogram (PCG) signal for heart rate estimation, and Electrocardiogram (ECG)-based Q, R, S detection.Comment: 29 pages, 30 figures, 5 tables.

The Promise of Health Information Technology: Ensuring that Florida's Children Benefit

Substantial policy interest in supporting the adoption of Health Information Technology (HIT) by the public and private sectors over the last 5 -- 7 years, was spurred in particular by the release of multiple Institute of Medicine reports documenting the widespread occurrence of medical errors and poor quality of care (Institute of Medicine, 1999 & 2001). However, efforts to focus on issues unique to children's health have been left out of many of initiatives. The purpose of this report is to identify strategies that can be taken by public and private entities to promote the use of HIT among providers who serve children in Florida

KALwEN: a new practical and interoperable key management scheme for body sensor networks

Key management is the pillar of a security architecture. Body sensor networks (BSNs) pose several challenges–some inherited from wireless sensor networks (WSNs), some unique to themselves–that require a new key management scheme to be tailor-made. The challenge is taken on, and the result is KALwEN, a new parameterized key management scheme that combines the best-suited cryptographic techniques in a seamless framework. KALwEN is user-friendly in the sense that it requires no expert knowledge of a user, and instead only requires a user to follow a simple set of instructions when bootstrapping or extending a network. One of KALwEN's key features is that it allows sensor devices from different manufacturers, which expectedly do not have any pre-shared secret, to establish secure communications with each other. KALwEN is decentralized, such that it does not rely on the availability of a local processing unit (LPU). KALwEN supports secure global broadcast, local broadcast, and local (neighbor-to-neighbor) unicast, while preserving past key secrecy and future key secrecy (FKS). The fact that the cryptographic protocols of KALwEN have been formally verified also makes a convincing case. With both formal verification and experimental evaluation, our results should appeal to theorists and practitioners alike

A Systematic Review of Research Studies Examining Telehealth Privacy and Security Practices Used By Healthcare Providers

The objective of this systematic review was to systematically review papers in the United States that examine current practices in privacy and security when telehealth technologies are used by healthcare providers. A literature search was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P). PubMed, CINAHL and INSPEC from 2003 – 2016 were searched and returned 25,404 papers (after duplications were removed). Inclusion and exclusion criteria were strictly followed to examine title, abstract, and full text for 21 published papers which reported on privacy and security practices used by healthcare providers using telehealth.  Data on confidentiality, integrity, privacy, informed consent, access control, availability, retention, encryption, and authentication were all searched and retrieved from the papers examined. Papers were selected by two independent reviewers, first per inclusion/exclusion criteria and, where there was disagreement, a third reviewer was consulted. The percentage of agreement and Cohen’s kappa was 99.04% and 0.7331 respectively. The papers reviewed ranged from 2004 to 2016 and included several types of telehealth specialties. Sixty-seven percent were policy type studies, and 14 percent were survey/interview studies. There were no randomized controlled trials. Based upon the results, we conclude that it is necessary to have more studies with specific information about the use of privacy and security practices when using telehealth technologies as well as studies that examine patient and provider preferences on how data is kept private and secure during and after telehealth sessions.Keywords: Computer security, Health personnel, Privacy, Systematic review, Telehealth

A Novel Secure Patient Data Transmission through Wireless Body Area Network: Health Tele-Monitoring

The security of sensitive data obtained from a patient has not been implemented properly because of energy issues of sensor nodes in Wireless Body Area Network (WBAN) and constrained resources such as computational power and low battery life. The main of this paper is to enhance the security level of data transmission between patient and health service provider by considering the availability of energy at sensor nodes. The proposed system consists of a hybrid Advanced Encryption Standard (AES) and Elliptic Curve Cryptography (ECC), which provides simple, fast and high cryptographic strength of data security. ECC is used for securing AES encryption keys, and AES algorithm is used for encrypting/decrypting text. A scenario where sensor nodes are continuously supplied energy from solar power is considered and based upon the energy availability; respective encryption technique is implemented. The result shows that the proposed EEHEE algorithm increases the encryption of the data file by more than 19% compared to the State of Art's solution. The proposed EEHEE system is 11% faster in encrypting data file and reduces the energy consumption by 34 % compared to the current best solution.  The proposed system concentrates on reducing the energy consumption in WBAN and increasing cryptographic strength to the system by using the hybrid symmetric and asymmetric algorithm. Thus, this study provides an efficient scheme to enhance security for real-time data transmission in telemedicine

MedLAN: Compact mobile computing system for wireless information access in emergency hospital wards

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.As the need for faster, safer and more efficient healthcare delivery increases, medical consultants seek new ways of implementing a high quality telemedical system, using innovative technology. Until today, teleconsultation (the most common application of Telemedicine) was performed by transferring the patient from the Accidents and Emergency ward, to a specially equipped room, or by moving large and heavy machinery to the place where the patient resided. Both these solutions were unpractical, uneconomical and potentially dangerous. At the same time wireless networks became increasingly useful in point-of-care areas such as hospitals, because of their ease of use, low cost of installation and increased flexibility. This thesis presents an integrated system called MedLAN dedicated for use inside the A&E hospital wards. Its purpose is to wirelessly support high-quality live video, audio, high-resolution still images and networks support from anywhere there is WLAN coverage. It is capable of transmitting all of the above to a consultant residing either inside or outside the hospital, or even to an external place, thorough the use of the Internet. To implement that, it makes use of the existing IEEE 802.11b wireless technology. Initially, this thesis demonstrates that for specific scenarios (such as when using WLANs), DICOM specifications should be adjusted to accommodate for the reduced WLAN bandwidth. Near lossless compression has been used to send still images through the WLANs and the results have been evaluated by a number of consultants to decide whether they retain their diagnostic value. The thesis further suggests improvements on the existing 802.11b protocol. In particular, as the typical hospital environment suffers from heavy RF reflections, it suggests that an alternative method of modulation (OFDM) can be embedded in the 802.11b hardware to reduce the multipath effect, increase the throughput and thus the video quality sent by the MedLAN system. Finally, realising that the trust between a patient and a doctor is fundamental this thesis proposes a series of simple actions aiming at securing the MedLAN system. Additionally, a concrete security system is suggested, that encapsulates the existing WEP security protocol, over IPSec

The Telehealth Chain: a protocol for secure and transparent telemedicine transactions on the blockchain

Blockchain technology provides a secure and decentralized platform for storing and transferring sensitive medical data, which can be utilized to enable remote medical consultations. This paper proposes a theoretical framework for creating a blockchain-based digital entity to facilitate telemedicine services. The proposed framework utilizes blockchain technology to provide a secure and reliable platform for medical practitioners to remotely interact with patient transactions. The blockchain will serve as a one-stop digital service to secure patient data, ensure privacy, and facilitate payments. The proposed framework leverages the existing Hyperledger Fabric platform to build a secure blockchain-assisted telemedicine platform
