Abstract: Cloud computing has revolutionized the way data is stored, processed, and shared by providing scalable, flexible, and on-demand access to computational resources over the internet. It has enabled individuals, enterprises, and government organizations to efficiently manage large volumes of data without investing heavily in physical infrastructure. Despite these advantages, the rapid adoption of cloud platforms has introduced significant challenges related to data security, privacy preservation, and fine-grained access control. Since data is stored on third-party servers, users lose direct control over their sensitive information, increasing the risk of unauthorized access, insider threats, and data breaches. Traditional encryption techniques such as symmetric and asymmetric cryptography ensure data confidentiality but fail to provide flexible and scalable access control mechanisms in dynamic, multi-user cloud environments. These methods rely heavily on complex key management systems and are not suitable for scenarios where access permissions need to be defined based on user roles, attributes, or contextual conditions. To address these limitations, Attribute-Based Encryption (ABE) has emerged as a powerful cryptographic approach that enables secure and flexible data sharing by enforcing access policies based on user attributes rather than identities. In particular, Ciphertext-Policy Attribute-Based Encryption (CP-ABE) allows data owners to define access structures directly within the encrypted data, ensuring that only users whose attributes satisfy the defined policies can decrypt and access the information. This paper presents the design and implementation of a secure and privacy-preserving data-sharing framework based on CP-ABE in cloud computing environments. The proposed system incorporates advanced security features such as fine-grained access control, secure key generation and distribution, user authentication, and protection against common attacks including collusion attacks and unauthorized data access. Additionally, privacy-preserving mechanisms are integrated to ensure that sensitive user attributes and data remain protected even from cloud service providers. The system architecture includes key components such as data owners, attribute authorities, cloud servers, and data users, working together to provide a secure and efficient data-sharing environment. Experimental evaluation demonstrates that the proposed framework significantly improves data security, reduces the risk of data breaches, and enhances access control efficiency compared to traditional encryption-based systems.

Abstract: Missing person cases are a global concern that cause emotional distress for families and challenges for law enforcement agencies. Traditional search methods such as posters, manual surveillance, and public announcements are slow and inefficient. This paper proposes FaceTrace, an artificial intelligence based missing person detection system that uses deep learning facial recognition to identify individuals from images and surveillance streams. The system leverages ArcFace embeddings, computer vision techniques, and a centralized MySQL database to match uploaded images with stored records. The proposed system enables faster identification and improves accuracy compared to manual methods.

Abstract: The rapid increase in construction activities has significantly increased the demand for water used in concrete curing. Conventional curing methods require continuous external water supply, which is often impractical in regions with water scarcity. This research focuses on self-curing concrete using Polyethylene Glycol (PEG-400) and Polyvinyl Alcohol (PVA) as internal curing agents. The study evaluates the mechanical properties of concrete, particularly compressive strength, by varying the percentage of these agents. The results demonstrate that self-curing concrete improves hydration, reduces shrinkage, enhances durability, and minimizes water consumption. The study concludes that PVA shows better performance compared to PEG in terms of strength and water retention.

Abstract: SocioMind AI is an AI-powered analytical framework that quantifies psychological states and personality traits through the automated processing of heterogeneous social media data. Unlike traditional sentiment analysis — which reduces complex human communication to a single positive/negative polarity score — SocioMind AI employs a multi-dimensional approach to construct a comprehensive "Linguistic DNA" profile of an individual, correlating public persona signals with private aspirational data to deliver a 360-degree behavioral footprint. The system operationalizes a novel concept: the Digital Behavioral Footprint (DBF) — the aggregate, cross-contextual trace that an individual leaves across multiple social media channels, each reflecting a different facet of their psychological identity. By processing and cross-referencing Primary Content, Interactional Tone, Interest Graphs, and Aspirational Signals simultaneously, SocioMind AI achieves what single-channel sentiment tools cannot: a holistic, internally-validated psychological portrait. At its inference core, SocioMind AI leverages the Gemini 3 Flash large language model architecture, optimized for structured JSON output to ensure deterministic, research-grade data handling. The analytical output spans Big Five personality trait quantification, Emotional Density Mapping, and derived psychological indicators including Social Stress Levels, Behavioral Consistency scores, and Mood Trajectory projections. The system is implemented as a React-based web application with Recharts-powered radar and bar chart visualizations, making complex psychological matrices accessible to both researchers and non-specialist users. Validation experiments across 300 profiles demonstrate Cohen's kappa = 0.74 for Big Five dimensions and Pearson r = 0.81 for emotional valence detection, establishing SocioMind AI as a viable zero-knowledge psychological proxy for research-grade personality inference.

Abstract: Public Wi-Fi networks in places like airports or cafés is convenient, but they are not very safe. Most people do not realize that these networks don’t usually have strong security and because of that, attackers can use methods like Man-in-the-Middle (MITM) attacks. One common method of MITM attacks is called ARP spoofing. In this method, a hacker tricks your device into sending data through their system instead of the real network. This usually happens in the background and the users don’t notice anything suspicous. As a result, important and personal information can be exposed and stolen without the user knowing. In this paper, I am proposind WiFiShield, a lightweight system or rather an application designed to detect such vulnerabilities in real time. Instead of being a heavy security suite, the application or system runs quietly in the background, sniffing network packets and double-checking the ARP table for any sudden, suspicious changes or spikes in the ARP requests. If the system sees a gateway address "flapping" or changing unexpectedly, it assigns a risk score and alerts the user immediately. I am aiming to make WiFiShield highly effective at spotting these hijacks without slowing down the computer. The application should be a simple, low-power solution for anyone who needs to stay connected on the go without leaving their personal data wide open to hackers.

Abstract: The proliferation of fake news on social media plat- forms poses significant threats to public discourse and democratic processes. While numerous machine learning approaches have been proposed for fake news detection, limited attention has been given to understanding why different models classify news as fake and whether these explanations are consistent across algorithms. This paper presents a comparative and explainable machine learning framework that addresses two critical research questions: (1) Do different ML models agree on which textual fea- tures indicate fake news? (Trust Gap Analysis), and (2) Do fake news patterns learned from one domain generalize to another? (Cross-Dataset Robustness). We evaluate four classical machine learning algorithms—Logistic Regression, Naive Bayes, Support Vector Machine, and Random Forest—using TF-IDF features on two distinct datasets: ISOT (political news, 44,898 articles) and WELFake (general news, 72,134 articles). Using SHAP (SHapley Additive exPlanations) for model interpretability, we compute Jaccard similarity and Spearman rank correlation to quantify agreement between model explanations. Our results reveal that different models exhibit varying levels of agreement on fake news indicators, with implications for model selection in real- world deployment. Furthermore, cross-dataset analysis identifies “universal” fake news features that generalize across domains versus “topic-specific” features that are domain-dependent. This work contributes a novel analytical framework for evaluating the trustworthiness and generalizability of fake news detection systems.

Abstract: The residential property market in Noida is complex due to its structured sector-based planning and the coexistence of Authority-developed plots and private high-rise housing societies. These two categories follow different pricing patterns, even within nearby areas. This study aims to develop a transparent price prediction model using Multiple Linear Regression to analyze the impact of hyperlocal features, particularly Metro connectivity, on property prices. A historical dataset of Noida properties was utilized and processed using Python and Pandas. The finalized regression model achieved approximately 85% accuracy on the testing dataset, revealing that Sector Location and Metro Connectivity are the most influential factors, often outweighing flat size. This demonstrates that a transparent regression approach can effectively support fair pricing in high-variance markets.

Abstract: Every year, forensic investigators and humanitarian groups are overwhelmed by thousands of missing people and unidentified bodies. However, traditional methods of identifica-tion are still very slow and prone to mistakes. AMPUIS, the AI-based missing person and Unidentified Body Identification System, solve this problem with a smart, real-time forensic framework. The system uses a ResNet-10-based Single Shot Multi-Box Detector to find faces, Open-face to extract deep embeddings that don’t change with pose, and a Support Vector Machine classifier to give probability scored identity verification. AMPUIS is built on a secure Flask web architecture that lets law enforcement and NGOs access it based on their roles. It has automated case management, severity-based alerts, and a live forensic dashboard. Experimental results show that this method is more accurate and faster than traditional biometric methods.It is also scalable and can be used all over the world for modern forensic identification.

Abstract: Innovative solutions that reduce human exposure to life-threatening risks are required because to the increasing frequency and severity of fire accidents in industrial settings, including petrochemical refineries, warehouses, power generation facilities, and chemical manufacturing plants. The methodical design, development, and experimental validation of an autonomous firefighting robot created especially for industrial deployment are presented in this work. The suggested platform combines an embedded multi-sensor array consisting of a FLIR Lepton 3.5 infrared thermal imager, Hamamatsu UV flame sensors, a Velodyne VLP-16 three-dimensional LiDAR, and electrochemical gas detectors with a thermally insulated omnidirectional Mecanum-wheel chassis. On an NVIDIA Jetson Orin NX computation module, FireDetNet-v2, a lightweight convolutional neural network trained on 45,000 annotated industrial fire pictures, achieves a mean average precision (mAP@0.5) of 97.6% at 30 frames per second. A 150-liter onboard water-AFFF suppression module uses a two-degree-of-freedom pan-tilt nozzle gimbal to administer agent at up to 12 bar, with a maximum throw range of 15 meters. GPS-denied autonomous navigation is made possible via simultaneous localization and mapping (SLAM) using the Cartographer framework using VLP-16 LiDAR data.
