Title: Privacy and Implementation Challenges in Contact Tracing Applications
Abstract: Digital contact tracing (CT) applications have emerged as one of the potential solutions to reduce the spread of the COVID-19 pandemic. Those applications come with several challenges in term of performances but most importantly in term of privacy. We discuss the main challenges associated with the implementation of those application. Covering the basic principle of CT applications, we present the main features of CT systems. A number of privacy risks associated to CT have been identified and two system model have been adopted leading to different trade-off in term of personal data protection. Last but not least, the use of Bluetooth as a mean to estimate proximity of contacts is associated with several issues regarding distance measurement reliability and limitations imposed by mobile operating systems.

Title: Effective Social Networking for Online Lecture Delivery
Abstract: Social network analysis has been shown valuable to comprehend various collective behavior in complex systems and networks, such as knowledge dissemination, modelling epidemics, and knowledge discovery from the data. Recently, due to the COVID-19 pandemic, people studying in schools and working in companies have to stay at home to remotely study or work utilizing online technology. In spite of continuing education and professional activities, the usual person-to-person interaction dynamic in schools and offices have been substantially impacted and significantly changed. In this paper, we examine the change in human interaction networks and consequent difficulties in forming social networks for inspiring discussion owing to remote interactions. Taking social network analysis, we suggest methods to increase social engagement of individuals affected by the remote technology in classes or work. The resulting network topology offers an insight as to how small-world networks are naturally formed, particularly in an online or online-offline setting.

Title: DETECT: Wearable Sensor Data to Predict COVID-19 and Viral Illnesses
Abstract: Digitalize human beings using biosensors to track our complex physiologic system, process the large amount of data generated with artificial intelligence (AI) and change clinical practice towards individualized medicine: these are the goals of digital medicine. In this talk, we discuss how to tackle the problem of COVID-19, we start with an overview of continuous, passively monitored vital signs from 200,000 individuals wearing a Fitbit wearable device for 2 years. This large study provides the baseline for DETECT, our app-based, nationwide clinical study enrolling individuals who routinely use a smartwatch or other wireless devices to determine if individualized tracking of changes in heart rate, activity and sleep can provide early diagnosis and self-monitoring for COVID-19. We analyze data from more than 36,000 individuals, showing how we can discriminate (on an individual level) between COVID-19 and other types of infections. We discuss how this can impact both the individual and public health, and how the use of AI can be a game changer in this fight against the virus.

Title: AR/VR Smart Health Service and Technologies for 5G and Beyond
Abstract: Recent developments in Virtual Reality (VR) and Augmented Reality (AR) have gained much interest in their adoption and enabled a new way of working, communications, and entertainment. Since the outbreak of COVID-19, hospital contact visits have been discouraged under social distancing and quarantine practices. As a result, the demand for remote healthcare grows significantly, where AV/VR smart health technology can be a key enabler to it. However, to deliver immersive experiences with high-resolution AR/VR services, it requires intensive computation capability and massive communication bandwidth with ultra-low latency for transmissions, which cannot be handled with current wireless technology. The advent of 5G and beyond (B5G) is expected to significantly boost mobile data rates and address the low latency problem via mobile edge computing (MEC). In this talk, we will present an intelligent B5G AR/VR streaming system for smart health service, which is expected to bring innovative healthcare experience to citizens. The core technologies include: MEC-based streaming, AI-enabled wireless resource management, and AR/VR service design. The developed smart AR/VR healthcare service has been deployed at major hospitals for field trials in Taiwan supported by a 5G/MEC operator and VR technology manufacturers.

Title: Evaluating Bluetooth-based Decentralized Contact Tracing in Crowds
Abstract: Digital contact tracing is being used by many countries to help contain COVID-19's spread in a post-lockdown world. Among the various available techniques, decentralized contact tracing that uses Bluetooth received signal strength indication (RSSI) to detect proximity is considered less of a privacy risk than approaches that rely on collecting absolute locations via GPS, cellular-tower history, or QR-code scanning. As of October 2020, there have been millions of downloads of such Bluetooth-based contract-tracing apps, as more and more countries officially adopt them. However, the effectiveness of these apps in the real world remains unclear due to a lack of empirical research that includes realistic crowd sizes and densities. This study aims to fill that gap, by empirically investigating the effectiveness of Bluetooth-based contact tracing in crowd environments with between 30 and 50 participants, emulating classrooms, moving lines, and other types of real-world gatherings. The results confirm that Bluetooth RSSI is unreliable for detecting proximity, and that this inaccuracy worsens in environments that are especially crowded. In other words, this technique may be least useful when it is most in need, and that it is fragile when confronted by low-cost jamming. Moreover, technical problems such as high energy consumption and phone overheating caused by the contact-tracing app were found to negatively influence users' willingness to adopt it. On the bright side, however, Bluetooth RSSI may still be useful for detecting coarse-grained contact events, for example, proximity of up to 20m lasting for an hour. Based on our findings, we recommend that existing contact-tracing apps can be re-purposed to focus on coarse-grained proximity detection, and that future ones calibrate distance estimates and adjust broadcast frequencies based on auxiliary information.

Abstract: The outbreak of the coronavirus pandemic since the end of 2019 has been declared as a world health emergency by the World Health Organization, which raised the importance of an accurate mathematical epidemic dynamical model to predict the evolution of COVID-19. Replicator dynamics (RDs) are exclusively applied to many epidemic models, but they fail to satisfy the Nash stationarity and can only describe an unidirectional population flow between different states. In this paper, we proposed mean field evolutionary dynamics (MFEDs), inspired by the optimal transport theory and mean field games on graph, to model epidemic dynamics. We have compared the MFEDs with RDs theoretically. In particular, we show efficiency of MFEDs by modeling the evolution of COVID-19 in Wuhan, China. Furthermore, we analyze the effect of one-time social distancing as well as the seasonality of COVID-19 through the post-pandemic period.

Title: Privacy-Preserving Multi-Operator Contact Tracing for Early Detection of Covid19 Contagions

Abstract: The outbreak of coronavirus disease 2019 (Covid-19) is imposing a severe worldwide lock-down. Contact tracing based on smartphones' applications (apps) has emerged as a possible solution to trace contagions and enforce a more sustainable selective quarantine. However, a massive adoption of these apps is required to reach the critical mass needed for effective contact tracing. As an alternative, geo-location technologies in next generation networks (e.g., 5G) can enable Mobile Operators (MOs) to perform passive tracing of users' mobility and contacts with a promised accuracy of down to one meter. To effectively detect contagions, the identities of positive individuals, which are known only by a Governmental Authority (GA), are also required. Note that, besides being extremely sensitive, these data might also be critical from a business perspective. Hence, MOs and the GA need to exchange and process users' geo-locations and infection status data in a privacy-preserving manner. In this work, we propose a privacy-preserving protocol that enables multiple MOs and the GA to share and process users' data to make only the final users discover the number of their contacts with positive individuals. The protocol is based on existing privacy-enhancing strategies that guarantee that users' mobility and infection status are only known to their MOs and to the GA, respectively. From extensive simulations, we observe that the cost to guarantee total privacy (evaluated in terms of data overhead introduced by the protocol) is acceptable, and can also be significantly reduced if we accept a negligible compromise in users' privacy.

Title: A Scalable COVID-19 Screening Platform
Time: 11:45-12:07 Dec. 8 (Tue.) (local time in Taipei)
Author(s): Cristian Chilipirea, Stefan-Adrian Toma and Luciana Maria Morogan (Military Technical Academy Ferdinand I, Romania)
Abstract: The COVID-19 pandemic has put a strain on health facilities world-wide. Remote screening can lessen the burden on medical resources. Manual screening cannot be performed due to the large number of people that need to be screened. We are constructing an automated remote screening system for Romania. The system needs to support simultaneous use by many persons (presumably a significant part of the population). Considering the urgency, we propose a light- weight web-based application that can run even on low- resource server infrastructures. We considered using cloud services, however, due to privacy considerations regarding medical data and legal issues we designed the application to be able to run, but to not require cloud services. Some of the decisions that we made were to offload computation to the browser, limit the number of requests and construct a server architecture that uses buffers for writing to the database and that can scale different components.

Title: Aether - A Novel Method to Eliminate False Positives in Private Automated Contact Tracing
Time: 12:07-12:30 Dec. 8 (Tue.) (local time in Taipei)
Author(s): Satvik Dasari (Westwood High School, USA)
Abstract: Contact tracing has shown promise to mitigate the negative effects of serious infectious diseases, such as COVID-19. Contact tracing can identify people who have potentially been exposed to COVID-19, as well as to enforce quarantine rules. However, many of these methods store location data, and therefore present privacy concerns. Bluetooth technology provides an effective solution to avoid violating fundamental privacy rights. However, Bluetooth technology doesn't have a good way of knowing whether devices are on the same level or different levels. In the case of multistory buildings, false positives can occur between two people who are within close proximity but on different floors. This paper proposes a novel solution in which the built-in barometer in mobile devices is used in combination with Bluetooth to avoid false positives. This paper establishes the viability and effectiveness of the solution through various experiments to make the current Bluetooth contact tracing technology even more accurate, which will ultimately save countless lives.
