“…This type of communication is enabled by two physical properties: (1) At a frequency of less than 100 MHz, the wavelength of an electromagnetic signal is far greater than the size of the human body and the electric field around the body can be approximated as constant over time, i.e., the phase of the signal remains uniform anywhere close to the human body [3], and (2) the human body can be modeled as a conducting wire at low frequencies, i.e., capacitive near-field coupling establishes a closed loop for signal transmission [38]. c) Surface wave techniques: Surface techniques are often referred to as "on-body" or "near-body" transmission.…”

“…While some electromagnetic waves propagate through the body in a similar way as with capacitive coupling, usually, a significant amount radiates into the air [35]. In addition, as the signal propagates through the body it is attenuated considerably [3]. Unlike with capacitive coupling or galvanic coupling, there is no closed loop for signal transmission; the receiver just measures the intensity of the electromagnetic signal analogous to conventional radio frequency transmission.…”

Abstract-Device pairing is the problem of having two devices securely establish a key that can be used to secure subsequent communication. The problem arises every time two devices that do not already share a secret need to bootstrap a secure communication channel. Many solutions exist, all suited to different situations, and all with their own strengths and weaknesses.In this paper, we propose a novel approach to device pairing that applies whenever a user wants to pair two devises that can be physically touched at the same time. The pairing process is easy to perform, even for novice users. A central problem for a device (Alice) running a device pairing protocol, is determining whether the other party (Bob) is in fact the device that we are supposed to establish a key with. Our scheme is based on the idea that two devices can perform device pairing, if they are physically held by the same person (at the same time). In order to pair two devices, a person touches a conductive surface on each device. While the person is in contact with both devices, the human body acts as a transmission medium for intra-body communication and the two devices can communicate through the body. This body channel is used as part of a pairing protocol which allows the devices to agree on a mutual secret and, at the same time, extract physical features to verify that they are being held by the same person. We prove that our device pairing protocol is secure in our threat model and we build a proof of concept set-up and conduct experiments with 15 people to verify the idea in practice.

“…A theoretical model, wherein the electric field was assumed to be composed of near field, inductive field, and far-field, was proposed by Bae et al [52] for the capacitive coupling HBC. The quasistatic field modelling of galvanic coupling HBC was developed by Pun et al [47,53].…”

Human body communication (HBC), which uses the human body tissue as the transmission medium to transmit health informatics, serves as a promising physical layer solution for the body area network (BAN). The human centric nature of HBC offers an innovative method to transfer the healthcare data, whose transmission requires low interference and reliable data link. Therefore, the deployment of HBC system obtaining good communication performance is required. In this regard, a tutorial review on the important issues related to HBC data transmission such as signal propagation model, channel characteristics, communication performance, and experimental considerations is conducted. In this work, the development of HBC and its first attempts are firstly reviewed. Then a survey on the signal propagation models is introduced. Based on these models, the channel characteristics are summarized; the communication performance and selection of transmission parameters are also investigated. Moreover, the experimental issues, such as electrodes and grounding strategies, are also discussed. Finally, the recommended future studies are provided.

The authors present a proposal to develop intelligent assisted living environments for home based healthcare in the presence of multimorbidity chronic patients. These environments unite the chronicle patient clinical history sematic representation ICP (Individual Care Process) with the ability of monitoring the living conditions using IoT technologies and events recurring to a fully managed Semantic Web of Things (SWoT) and Machine Learning Algorithms in order to activate the LDC (Less Differentiated Caregiver) for a specific care need. With these capabilities at hand, home based healthcare providing becomes a viable possibility reducing the institutionalization needs. The resulting integrated healthcare framework will provide significant savings while improving the generality of health and satisfaction indicators.
