WHAT PREVENTS THE OPTIMAL Galvanic Coupled HBC (GC-HBC) IN THE INTERNET OF BODIES?
Best insight from top research papers
The optimal performance of Galvanic Coupled Human Body Communication (GC-HBC) in the Internet of Bodies is hindered by several factors. One of the main challenges is the dependency of the channel behavior on various internal and external parameters, such as the electrical properties of skin and muscle tissue layers, electrode size, electrode separation, and geometrical position of the electrodes . Another factor is the mismatch at the transmitter and receiver ends, which can lead to increased channel loss and dominance of capacitive HBC even for galvanic excitation and termination . Additionally, the measurement process of the actual gain through the human body in intrabody communication (IBC) poses technical challenges due to the heterogeneity of experimental setups and conditions . Furthermore, achieving high-data-rate galvanic coupling IBC systems is still a problem, limiting the development of implanted medical sensors . Finally, while GC-HBC provides impermeability to malicious attacks, eavesdropping susceptibility of GC-signals and similar body communication techniques over-the-air and in direct contact with the medium can be a concern .

Interfacial reaction between electrode and body when apply voltage across human body?4 answersThe interfacial reaction between an electrode and the human body when applying voltage across the body is an important consideration in various applications such as biopotential sensing and human body communication. The body-electrode interface acts as a transducer, converting ionic current in the body to electronic current in the circuits and vice versa. However, practical body-electrode interfaces often have impedances and potentials that hinder the free flow of currents, affecting the performance of the application. To measure the interfacial impedance between the body and a stimulating electrode, an apparatus has been developed that extracts voltages loaded on the electrodes and calculates the impedance based on the digital signal and applied current. Additionally, a device has been proposed to measure the voltage accumulated in the human body and discharge it through a receptacle unit, ensuring safety and preventing reverse voltage supply. Galvanic coupling is another approach for intrabody data transmission, where the coupling of current into the human body is optimized for safety and signal quality. Understanding the human body impedance and taking safety measures such as using insulated cables and protective clothing can significantly reduce the risk of electric shocks and electrocution.
What is Body Area Networks?4 answersA body area network (BAN) is a network of low-power devices, including smart sensors, situated on or around the human body to monitor physiological and motion information for various applications such as healthcare, sports, and security. It provides connectivity and power among these sensors, enabling the creation of a "human intranet". WBANs (wireless body area networks) are a type of BAN that utilize wireless technologies such as IEEE 802.11, IEEE 802.15.4, and IEEE 802.15.6. Reliability is a crucial aspect of WBANs, and research has been conducted on reliability modeling, analysis, and designs for WBANs. Routing protocols play a significant role in WBANs, affecting energy efficiency, topology, temperature, location, and quality of service. The goal is to achieve energy effectiveness and efficient transmission processes for remote monitoring of wearable system data.
How can privacy and security risks in the Internet of Medical Things for healthcare monitoring systems be addressed?4 answersPrivacy and security risks in the Internet of Medical Things (IoMT) for healthcare monitoring systems can be addressed through various measures. Firstly, it is crucial to examine the available security and privacy measures in the IoMT space to protect sensitive individual health information. Vulnerabilities in IoT devices can lead to unauthorized access, insecure communications, and data breaches, so implementing proper authentication and authorization, secure communication protocols, and appropriate software updates is essential. Additionally, the use of authentication schemes, such as digital signatures and Authenticated Key Exchange (AKE) protocols, can ensure that only authorized entities have access to medical services. Privacy concerns can be mitigated by implementing privacy-by-design principles, raising awareness among users, and promoting responsible data collection practices. By implementing recognized safeguards, the risk of exploiting vulnerabilities can be greatly reduced, ensuring the security and privacy of IoMT systems in healthcare monitoring.
What are the most pressing security issues in the Internet of Things?5 answersThe most pressing security issues in the Internet of Things (IoT) include resource constraints leading to vulnerability to cyber-attacks, unauthorized access and insecure communications, inadequate device updates and a lack of robust safeguards. Additionally, improper authentication and authorization, insecure communication protocols, and inappropriate software updates pose significant risks to IoT devices and networks. Privacy concerns arise from the collection and processing of sensitive user data without proper consent and lack of privacy-by-design principles. To address these issues, proposed solutions include ensuring security in IoT networks through dark-net traffic detection systems, privacy provisioning, lightweight cryptographic frameworks, secure routing, and protection against DoS attacks. Researchers have also proposed a layered paradigm with security and privacy tools for the deployment and evaluation of virtualized IoT systems.
What are the key information security concerns in IoT components of eHealth?3 answersKey information security concerns in IoT components of eHealth include the protection of sensitive health information against cybercrime attacks and the associated risks in healthcare systems. Privacy and security issues surrounding data transfer, processing, monitoring, and documentation are also significant concerns. The complexities of IoT security have increased with the variations of IoT devices, posing a notable risk of attackers gaining control of medical IoT devices and altering the collected data. In the establishment of a software product line for eHealth IoT systems, the adoption of systematic security and privacy threat modeling and risk assessment approaches introduces a variation space that is difficult to capture in a proactive approach. The IoT healthcare system faces challenges that need to be addressed, such as ensuring stability and ubiquity, and addressing concerns related to IoT security.
