A Location Based Safety Application for Enhancing Women’s Safety

Women’s safety remains a critical and urgent concern, as evidenced by the increasing incidence of harassment and violence, necessitating the development of innovative, technology-driven solutions. Although numerous mobile applications have been designed to address this issue, many fails to deliver essential functionalities. These deficiencies include the lack of real-time emergency response mechanisms, seamless tracking capabilities, and proactive safety features that meaningfully enhance user protection. Often, these applications rely on outdated alert systems and exhibit delayed SOS notifications, undermining their effectiveness in critical situations. To address these shortcomings, ‘Shield Sisters’ was developed as a Flutter-based mobile application aimed at equipping women with reliable and practical safety tools. The application integrates instant SOS alerts, real-time location tracking, an intelligent geofencing system, and a community-driven safety reporting mechanism. Its robust technological infrastructure comprises MongoDB, Node.js, and Firebase Firestore for efficient backend operations, the Twilio API for immediate emergency SMS notifications, and the Google Maps API for precise, real-time geolocation services. Shield Sisters classifies locations into Safe Zones (e.g., police stations and hospitals), Red Zones (e.g., high-risk areas), and Neutral Zones, providing users with timely warnings before entering potentially dangerous areas. Furthermore, its live tracking feature updates the user’s location every ten seconds, enabling trusted contacts to monitor movements with accuracy. To ensure security and privacy, Shield Sisters employs SHA-256 encryption for password protection, JWT-based authentication for user verification, and role-based access controls to restrict emergency contact privileges. The application’s performance, scalability, and security were rigorously evaluated using Flutter’s testing framework, Thunder Client for API validation, and stress testing to assess server load capacity. Designed for speed, scalability, and dependability, Shield Sisters offers a trustworthy solution that users can rely upon in moments of need.
