Understanding security risks and users perception towards adopting wearable Internet of Medical Things

This thesis examines users’ perception of trust within the context of security and privacy of Wearable Internet of Medical Things (WIoMT). WIoMT is a collective term for all medical devices connected to internet to facilitate collection and sharing of health-related data such as blood pressure, heart rate, oxygen level and more. Common wearable devices include smart watches and fitness bands. WIoMT, a phenomenon due to Internet of Things (IoT) has become prevalent in managing the day-to-day activities and health of individuals. This increased growth and adoption poses severe security and privacy concerns. Similar to IoT, there is a need to analyse WIoMT security risks as they are used by individuals and organisations on regular basis, risking personal and confidential information. Additionally, for better implementation, performance, adoption, and secured wearable medical devices, it is crucial to observe users’ perception. Users’ perspectives towards trust are critical for adopting WIoMT. This research aimed to understand users’ perception of trust in the adoption of WIoMT, while also exploring the security risks associated with adopting wearable IoMT. Employing a quantitative method approach, 189 participants from Western Sydney University completed an online survey. The results of the study and research model indicated more than half of the variance (R2 = 0.553) in the Intention to Use WIoMT devices, which was determined by the significant predictors (95% Confidence Interval; p < 0.05), Perceived Usefulness, Perceived Ease of Use and Perceived Security and Privacy. Among these two, the domain Perceived Security and Privacy was found to have significant outcomes. Hence, this study reinforced that a WIoMT user intends to use the device only if he/she trusts the device; trust here has been defined in terms of its usefulness, easy to use and security and privacy features. This finding will be a steppingstone for equipment vendors and manufacturers to have a good grasp on the health industry, since the proper utilisation of WIoMT devices results in the effective and efficient management of health and wellbeing of users. The expected outcome from this research also aims to identify how users’ security and perception matters while adopting WIoMT, which in future can benefit security professionals to examine trust factors when implementing new and advanced WIoMT devices. Moreover, the expected result will help consumers as well as different healthcare industry to create a device which can be easily adopted and used securely by consumers

The Impacts of Privacy Rules on Users' Perception on Internet of Things (IoT) Applications: Focusing on Smart Home Security Service

Department of Management EngineeringAs communication and information technologies advance, the Internet of Things (IoT) has changed the way people live. In particular, as smart home security services have been widely commercialized, it is necessary to examine consumer perception. However, there is little research that explains the general perception of IoT and smart home services. This article will utilize communication privacy management theory and privacy calculus theory to investigate how options to protect privacy affect how users perceive benefits and costs and how those perceptions affect individuals??? intentions to use of smart home service. Scenario-based experiments were conducted, and perceived benefits and costs were treated as formative second-order constructs. The results of PLS analysis in the study showed that smart home options to protect privacy decreased perceived benefits and increased perceived costs. In addition, the perceived benefits and perceived costs significantly affected the intention to use smart home security services. This research contributes to the field of IoT and smart home research and gives practitioners notable guidelines.ope

Conceivable security risks and authentication techniques for smart devices

With the rapidly escalating use of smart devices and fraudulent transaction of users’ data from their devices, efficient and reliable techniques for authentication of the smart devices have become an obligatory issue. This paper reviews the security risks for mobile devices and studies several authentication techniques available for smart devices. The results from field studies enable a comparative evaluation of user-preferred authentication mechanisms and their opinions about reliability, biometric authentication and visual authentication techniques

Exploring the use of conversational agents to improve cyber situational awareness in the Internet of Things (IoT).

The Internet of Things (IoT) is an emerging paradigm, which aims to extend the power of the Internet beyond computers and smartphones to a vast and growing range of "things" - devices, processes and environments. The result is an interconnected world where humans and devices interact with each other, establishing a smart environment for the continuous exchange of information and services. Billions of everyday devices such as home appliances, surveillance cameras, wearables and doorbells, enriched with computational and networking capabilities, have already been connected to the Internet. However, as the IoT has grown, the demand for low-cost, easy-to-deploy devices has also increased, leading to the production of millions of insecure Internet-connected smart devices. Many of these devices can be easily exploited and leveraged to perform large-scale attacks on the Internet, such as the recently witnessed botnet attacks. Since these attacks often target consumer-level products, which commonly lack a screen or user interface, it can be difficult for users to identify signs of infection and be aware of devices that have been compromised. This thesis presents four studies which collectively explored how user awareness of threats in consumer IoT networks could be improved. Maintaining situational awareness of what is happening within a home network is challenging, not least because malicious activity often occurs in devices which are not easily monitored. This thesis evaluated the effectiveness of conversational agents to improve Cyber Situational Awareness. In doing so, it presented the first study to investigate their ability to help users improve their perception of smart device activity, comprehend this in the context of their home environment, and project this knowledge to determine if a threat had occurred or may occur in the future. The research demonstrated how a BLSTMRNN with word embedding could be used to extract semantic meaning from packets to perform deep packet inspection and detect IoT botnet activity. Specifically, how the models use of contextual information from both the past and future enabled better predictions to be made about the current state (packet) due to the sequential nature of the network traffic. In addition, a cross-sectional study examined users' awareness and perception of threats and found that, although users value security and privacy, they found it difficult to identify threats and infected devices. Finally, novel cross-sectional and longitudinal studies evaluated the use of conversational agents, and demonstrated them to be an effective and efficient method of improving Cyber Situational Awareness. In particular, this was shown to be true when using a multi-modal approach and combining aural, verbal and visual modalities

Data Disparity: Tiered Pricing as an Alternative to Consumer IoT Data Privacy Regulations

In recent years, Internet of Things (IoT) devices have exploded on the consumer scene. These emerging products bring new technological capabilities into our everyday lives. IoT is projected to contribute anywhere from $4-11 trillion to the global economy and companies are investing billions of dollars into the technology. However, with the vast amount of data that IoT devices collect, consumers are burdening the risk of having their personal data breached or sold to third parties. This paper first identifies why consumers may be weary or willing towards providing their personal data and how unconscious biases in the purchasing process cause consumers to misperceive their level of risk. Then, the impact of potential regulations that may be enacted are analyzed. Finally, a study is conducted that tests consumers’ purchasing behavior around a smart speaker that is offered under a three-tier price model providing three different levels of data privacy. From this study, a two-tier price model is proposed as an effective measure towards ensuring greater equality in the personal data trade between consumers and sellers, and a proactive alternative to regulations that may create new challenges for both parties

Pedestrian Detection with Wearable Cameras for the Blind: A Two-way Perspective

Blind people have limited access to information about their surroundings, which is important for ensuring one's safety, managing social interactions, and identifying approaching pedestrians. With advances in computer vision, wearable cameras can provide equitable access to such information. However, the always-on nature of these assistive technologies poses privacy concerns for parties that may get recorded. We explore this tension from both perspectives, those of sighted passersby and blind users, taking into account camera visibility, in-person versus remote experience, and extracted visual information. We conduct two studies: an online survey with MTurkers (N=206) and an in-person experience study between pairs of blind (N=10) and sighted (N=40) participants, where blind participants wear a working prototype for pedestrian detection and pass by sighted participants. Our results suggest that both of the perspectives of users and bystanders and the several factors mentioned above need to be carefully considered to mitigate potential social tensions.Comment: The 2020 ACM CHI Conference on Human Factors in Computing Systems (CHI 2020
