A Privacy-Preserving Approach to Health Insurance Fraud Detection Using Vertical Federated Learning Raghi K R, Arjun Paramarthalingam, Harini Kanthan, Mahalakshmi Karthiban Sensors, 2025 In fraud detection, centralized approaches often face challenges related to data protection, security, and potential data breaches. Such methods require sensitive healthcare and insurance data to be pooled in one location, which increases vulnerability to misuse. This paper introduces FraudNetX, a privacy-preserving fraud detection framework, by utilizing Vertical Federated Learning (VFL) to address centralized system limitations. VFL enables models to be trained collaboratively while ensuring data privacy and security through quantifiable Differential Privacy (DP) guarantees (ε = 1.0, δ = 1 × 105). FraudNetX implements a noise injection based on Differential Privacy (DP) with Gaussian noise (s = 1.2) in the process of training the model to guarantee confidentiality of the personal data. This research entails two partner organizations, which are a hospital and an insurance company, in an actual VFL configuration. The model is trained on 10 communication rounds in this federated setup, and the local optimization of each client is followed by the global aggregation step. Hospitals and insurers can learn fraud patterns without sharing their data. The proposed FraudNetX is a hybrid architecture which is composed of Feedforward Neural Networks (FFNNs) and transformer encoders. An adaptive weighting strategy has been applied to handle category imbalance concern and enhance recall of a few categories which are hard to detect, especially in fraud involving minorities, balancing the recall performance. The framework also includes a decision model that uses hospital data and claim behavior to classify each claim as legitimate, under review, or fraudulent. The experimental evaluation on the real-world dataset demonstrates that FraudNetX enhances the accuracy and F1-score of fraud detection (accuracy = 99.91%, F1 = 99.94%, ROC-AUC = 0.98) but does not violate data privacy.
AI-Driven Chatbot for Mental Health Analysis Using Transformer Models Arjun Paramarthalingam, Amirthasaravanan Arivunambi, Ashokkumar Janarthanan, Sindhuja Sundaresan, Srinivas saravanan Ariyangavu Premier Journal of Science, 2025 This Mental Wellness Chatbot is a software-based solution created for the purpose of solving the incomplete alleviation of depression symptoms in a person. This mental wellness Companion is a chatbot that act as a normal chatbot while mainly focus on the mental health of the user. To accomplish this, we are going to be use various techniques and algorithms to create this chatbot. We are going to use API token of a pre-trained hugging face model in order to create this chatbot rather than using the Large Language Model (LLM) locally since executing the chatbot locally requires a lot of GPU power in the device in order to create and embed the data that we are providing as a dataset. Mainly we are going to be using a pre-trained model from the open-source hugging face model and we are not going to be using OpenAI for completing it. For the database we are going to be using the vector database Facebook AI Similarity Search (FAISS) instead of Mangodb. The mental health Chatbot app is like a reliable friend in the pocket, always ready to lend an ear and offer support whenever you need it. Through gentle questions and personalized suggestions, it helps to navigate the emotions and find ways to feel better. By tracking persons progress over time, it creates a valuable record of emotional journey, empowering to understand oneself better. With 24/7 availability and a commitment to privacy and confidentiality, it provides a safe space for a person to express openly and honestly. Whether the person looking for coping strategies, educational insights, or connections to additional resources, the Chatbot app is there to guide a person on their path to emotional well-being.
AI-powered virtual mouse control through hand gestures with computer vision Arjun Paramarthalingam, Ashokkumar Janarthanan, Amirthasaravanan Arivunambi, Srinivas Saravanan Ariyangavu, Hariprasath Senthamaraikannan, Rekha Ganapathy Harnessing AI in Geospatial Technology for Environmental Monitoring and Management, 2024 This article introduces an Artificial Intelligence (AI) enabled virtual mouse system that utilizes hand gestures and fingertip detection to operate computer mouse functions through AI and computer vision techniques. It serves as a convenient alternative to traditional physical mouse, offering users increased flexibility and accessibility in navigating and controlling their devices. In this article, the proposed work uses three modules such as OpenCV, MediaPipe and PyautoGUI to create the virtual mouse system. OpenCV library is used for its real-time computer vision functionality to help us to capture the hand using the web camera. The MediaPipe framework is used to detect the hand region using KLT Tracking Algorithm and then the K-cosine border tracking algorithm is used to identify various types of hand gesture movements to mimic the computer mouse cursor movement and scrolling operations. The PyAutoGUI module is used to perform appropriate mouse actions based on the recognized hand gestures.
A deep learning model to assist visually impaired in pothole detection using computer vision Arjun Paramarthalingam, Jegan Sivaraman, Prasannavenkatesan Theerthagiri, Balaji Vijayakumar, Vignesh Baskaran Decision Analytics Journal, 2024 Visually impaired individuals encounter numerous impediments when traveling, such as navigating unfamiliar routes, accessing information, and transportation, which can limit their mobility and restrict their access to opportunities. However, assistive technologies and infrastructure solutions such as tactile paving, audio cues, voice announcements, and smartphone applications have been developed to mitigate these challenges. Visually impaired individuals also face difficulties when encountering potholes while traveling. Potholes can pose a significant safety hazard, as they can cause individuals to trip and fall, potentially leading to injury. For visually impaired individuals, identifying and avoiding potholes can be particularly challenging. The solutions ensure that all individuals can travel safely and independently, regardless of their visual abilities. An innovative approach that leverages the You Only Look Once (YOLO) algorithm to detect potholes and provide auditory or haptic feedback to visually impaired individuals has been proposed in this paper. The dataset of pothole images was trained and integrated into an application for detecting potholes in real-time image data using a camera. The app provides feedback to the user, allowing them to navigate potholes and increasing their mobility and safety. This approach highlights the potential of YOLO for pothole detection and provides a valuable tool for visually impaired individuals. According to the testing, the model achieved 82.7% image accuracy and 30 Frames Per Second (FPS) accuracy in live video. The model is trained to detect potholes close to the user, but it may be hard to detect potholes far away from the user. The current model is only trained to detect potholes, but visually impaired people face other challenges. The proposed technology is a portable option for visually impaired people.

Existing detection systems frequently rely on antiquated methodologies, resulting in low accuracy and efficiency. The study indicates a novel approach for detecting Mirai botnet activity that uses XGBoost, an advanced ensemble learning algorithm. The proposed system outperforms standard approaches in terms of performance measures by incorporating thorough data preparation, feature extraction, and selection methodologies, as well as efficient XGBoost model training. The results show a considerable improvement in accuracy (0.90), precision (0.89), recall (0.91), and F1 score (0.90), as well as a decrease in false positives (20) and false negatives (15). Furthermore, improved computational efficiency leads to shorter training and prediction timeframes, less memory utilization, and more responsive detection capabilities. Overall, the proposed system provides a strong framework for proactive detection and mitigation of Mirai botnet threats, which improves network security in real-world scenarios.
