    • Zero Trust Collaborative Drone Systems for Disaster Management
      Advisors: Dr. Prasad Calyam, Dr. Kannappan Palaniappan, Dr. Ekincan Ufuktepe
      Graduate Student Mentors: Alicia Esquivel
      Research Students: Cameron Grant, Samuel Elfrink
      Abstract: With the ability to extend the capabilities of cloud computing, mobile edge computing has become increasingly utilized. In numerous cases, edge routing mechanisms can be used with mobile ad-hoc networks (MANETs) to manage data network transmission in areas where conventional networks would fail. Securing these networks is challenging due to their stateless nature and resource constrained devices. In addition, MANETs pose challenges that traditional security frameworks are not designed to meet. The Zero Trust (ZT) paradigm can solve these issues by offering adaptable defense strategies. A ZT approach can take the static or network-based perimeter security that is found in traditional networks and shift the focus on users, assets, and resources, providing superior security mechanisms to these systems. In this paper, we propose a novel ZT security framework for intelligence-driven edge routing for a collaborative drone system application, modeling threats that focus on preventing and mitigating common attacks that occur within the packet and network-level of collaborative drone systems. Because of the resource constraints present in these systems, we implement our ZT framework with an emphasis on low overhead for resource-constrained devices with a novel architecture for offloading resource-dependent security tasks. This is accomplished by offloading the large computational tasks to an additional Ground Control Station (GCS) at the edge of the network that has the burden of the trust management. We show the impact of Denial Of Service (DoS), Blackhole and Man-in-the-Middle (MITM) attacks on a drone swarm collaborative system using a realistic testbed setup. Finally, we present our Trust Manager (TM) algorithms to detect and mitigate threats at the packet and network levels with low overhead of implementation.

    • ClaimChain: Secure Blockchain Platform for handling Insurance Claim Processing
      Advisors: Dr. Prasad Calyam, Dr. Khaza Anuarul Hoque
      Graduate Student Mentors: Naga Ramya Bhamidipati, Varsha Vakkavanthula, Ernest Bonnah
      Research Students: George Stafford, Masrik Dahir
      Abstract: Insurance claims processing involves multi-domain entities and multi-source data, along with a number of human—agent interactions. Consequently, this processing is traditionally manually-intensive and time-consuming. Blockchain technology-based solutions and intelligent automation can significantly improve the scale and response time of claims processing. However, there is a need to secure such platforms against fraud (e.g., duplicate claims) and the loss of data integrity via cyberattack (e.g., Sybil Attacks). In this paper, we propose a novel “ClaimChain” consortium Blockchain platform that advances the state-of-the-art NICB ISO database through increased shared intelligence, inviting all insurance companies to participate. Our contributions include: (a) automation of insurance claim processing via implementation as highly-scalable Blockchain transactions, (b) Infrastructure-level threat modeling via attack tree formalism for integrity attacks realizable in Claimchain, and (c) Application-level fraud modeling for identified prominent red flags utilizing machine learning models and risk scoring on the basis of risk severity. We further our threat model with quantitative analysis for probability of threat occurrences and use security design principles to significantly reduce their probability of success. We evaluate the scalability of ClaimChain by simulating 3000 Blockchain transactions. Further, we show that integrity attacks at the infrastructure-level can be mitigated through implementation of carefully designed security principles. We also perform fraud-detection over an experimental dataset to show how machine learning models can accurately detect fraudulent activity. Our results show that ClaimChain is effective in protecting the intelligent automation of the insurance claims processing as seen in reduction of 24% probability of loss of integrity before and after applying security design principles. Claimchain is also effective in detecting fraudulent activities with a detection accuracy of up to 98% for identified red flags.

    • Creating a new Knowledge Network for Ecological Momentary Assessment (EMA) on Addiction Studies
      Advisors: Dr. Yi Shang, Dr. Tim Trull
      Graduate Student Mentors: Justin Varghese, Fengxiang Zhao
      Research Students: Cade Winters, George Stafford
      Abstract: Domain-specific knowledge is necessary for critical analysis and decision-making in any scientific field. As a result, it is important that we have mechanisms for collecting and applying knowledge contributed by the larger scientific community. The current paradigm involves collecting knowledge in human-readable scientific papers across various scientific journals. Extracting useful information from these papers is a labor-intensive task and the growing population of papers makes it difficult to consider older works. The implementation of a knowledge network would allow for the automation of this process, but there is no existing pipeline for the reorganization of data collected through Ecological Momentary Assessment (EMA) into knowledge graphs. In this paper, we present EMA-KN, an automatically generated knowledge graph built using the AI-KG architecture. This architecture features state-of-the-art extraction by employing the DyGIE++ and StanfordCoreNLP tools. We test our pipeline using a dataset of 74 EMA-related papers and compare the output to that of AI-KG using a dataset of 74 CS-related papers to capture the success of knowledge graph construction. Further, we evaluate knowledge graph embedding using different metrics. Results show that our pipeline performs marginally worse than AI-KG, sacrificing triple quality for domain plug-ability. In the future, we seek to improve the system to match the performance of dedicated domain-specific solutions.

    • Virtual Reality and CAVE for Immersive Photorealistic Synthetic Environments
      Advisors: Dr. Kannappan Palaniappan, Dr. Bimal Balakrishnan
      Graduate Student Mentors: Jaired Collins
      Research Students: Calvin Davis, Emily Lattanzio
      Abstract: Drones are expensive, have a limited battery life, and are subjected to constantly changing climate conditions. With these limitations, it is imperative to develop drone flight planning and autonomy testbeds to make effective use of their limited air time. These testbeds should have a real-world and high-resolution synthetic environment to simulate the setting that the drone will be flying through. Our team addressed this problem through creating an end-to-end pipeline that models an urban city as a synthetic environment to be viewed through the Microsoft HoloLens. The methodology includes reconstructing multiple city scale point clouds into meshes using algorithms such as the ball pivot algorithm, Poisson surface reconstruction, and greedy surface triangulation. Furthermore, the research experimentally compares different meshing platforms to reveal MeshLab as the most ideal option for the creation of simple meshes. With the application of a custom texture-mapping python script, we show that the models achieve a photo realistic look through utilization of a 4400 by 6600 image dataset. Our rendered 3D models and pipeline are available to labs in the battlefield to experiment optimal drone flight paths. In addition to that, this reconstruction and viewing pipeline can be used for further research such as flight training for commercial aircraft, city planning, car safety research in real-time traffic simulations, and video games.

    • Sleep Stage Classification Using Deep Learning
      Advisors: Dr. Marjorie Skubic
      Graduate Student Mentors: Ruhan Yi
      Research Students: Hosanna Tesfaye, Kelly Ryoo, Nikhil Vyas
      Abstract: Sleep stage classification can be used to monitor sleep quality and diagnose sleep disorders. Sleep disorders can be correlated to health conditions such as Alzheimer's and Parkinson's disease. This project uses a hydraulic bed sensor positioned under the mattress, as well as a deep learning approach, for sleep stage classification. Our motivation is to provide an automatic, non-invasive and more accessible method of classifying sleep stages by using deep learning to analyze data gathered from the hydraulic bed sensor. The test subjects for this project were elderly patients with sleep disorders. Polysomnography (PSG) data, the current gold standard, was also collected in a Sleep Lab to serve as the ground truth for the bed sensor data. In this study, sleep stages are categorized into 3 categories: Wake, Rapid Eye Movement (REM), and Non-Rapid Eye Movement (NREM). This paper uses a Convolutional Neural Network (CNN)- Long-Short Term Memory (LSTM) hybrid model with 2 CNNs of different filter sizes for feature extraction. These features are then fed into the LSTM for classification. Our results show an average accuracy of about 75.5% using leave one subject out cross validation. These results are promising and show that the hydraulic bed sensor combined with a deep learning approach is capable of providing an automatic and non-invasive method of classifying sleep stages.
