The proposed system gives priority to self-defense by providing safety and helping women in critical situations. It also tends to implement a device that is triggered without any manual aid, providing safety for women in public transport vehicles such as cabs, taxis, buses, auto rickshaws. The main aim of the project is to implement wearable IoT devices built with the Raspberry Pi, which includes a sound sensor, camera module, GPS, and GSM. When the sound sensor detects screaming, the machine learning SVM (support vector machine) algorithm removes superfluous noise and analyses just the victim's screaming. After analyzing the victim's scream, the device immediately activates the camera module, which records 10 seconds of video. The GPS module will track the geographical locations and, using the GSM module, will send an alert message as well as an emergency call to the nearest police station. In the second scenario, when the victim flips the switch, the camera module is immediately enabled and a 10-second clip is recorded. The GPS will be active, and GSM will transmit a status alert message. The procedure's primary objective is to provide a smart device for a lady that is both comfortable and portable. The smart band's capacity to minimize the size of gadgets is the first and most important distinction between it and other existing safety measures[16].
