A Smart IoT-Based Safety System for Vulnerable Populations: An Innovative Approach Using AI and Blockchain

In an increasingly digital world, safety remains a critical concern, especially for vulnerable populations such as women, children, and the elderly. This research presents an advanced IoT-based smart wearable safety device integrating artificial intelligence (AI) and blockchain technologies to enhance personal security. The system incorporates sensors for monitoring physiological and environmental parameters, a GPS module for real-time location tracking, and a high-frequency alarm. Blockchain ensures secure data transmission and tamper-proof records, while AI enhances threat detection through sentiment analysis and machine learning-based pattern recognition. Experimental results demonstrate an accuracy of 96.8%, a sensitivity of 94.3%, and a robust safety response mechanism. The proposed solution offers scalable, energy-efficient, and cost-effective protection, setting a benchmark for IoT-based safety systems.
