SHAKTI: Women Safety Device

Abstract

In our Country, even though it has a superpower and economic development, there are still many crimes against women. The atrocities against women can be brought to an end with the help of our product “Shakti”. This device is a security system, specially designed for women in distress. Method/Analysis: Using ESP32 for the hardware device is the most efficient and it consumes less power. We use radio frequency signal detectors to detect hidden cameras. Findings: We analyzed that there are no security devices for our total safety. The user has to carry multiple devices. We found an ALL-IN-ONE security device that has all the features in one click or Gesture. Applications/Improvements: In this paper we used ESP32 and Android applications in which both the device and the smartphone are synchronized using Bluetooth, hence both can be triggered independently. We can record audio for further investigation and can give an alert call and message to the pre-set contacts with the instant location every 2 minutes and can be tracked live using our application. A hidden camera detector is also a distinct feature using which we can ensure our privacy.

Introduction

Shakti is a personal safety device and smartphone application designed specifically for women in distress or emergency situations. It combines hardware and mobile app functionalities to:

• Send emergency alerts,

• Share live location,

• Record evidence (audio/video),

• Detect hidden cameras,

• Work without internet when necessary.

It offers real-time protection 24/7 and is easy to use, activated via a button press or voice command (e.g., shouting "HELP").

2. Key Use Cases

“Shakti” aids in preventing and responding to:

• Stalking

• Assault attempts

• Domestic violence

• Unsafe environments

• Hidden surveillance

3. Literature Review Highlights

Past safety devices inspired this system:

• FEMME: Integrated safety tool but lacked live surveillance features.

• Smart Wearable (IoT-based): Used GPS/GSM but no audio/video support.

• Bluetooth-Based Safety System: Relied on nearby phones and lacked autonomy.

4. Proposed System Overview

Hardware Components

• ESP32 Microcontroller: Central controller

• GPS & GSM Modules: Real-time tracking and SMS alerting

• Voice Recorder (ISD1820): Captures emergency audio

• Sound Sensor (LM393): Activates SOS on hearing “HELP”

• Bluetooth Module (HC-05): Enables remote SOS activation

• Hidden Camera Detector: Alerts presence of surveillance devices

• OLED Display: Shows system status and location

• Push Button: Triggers various actions (SMS, audio recording, calls)

Power Requirement: Operates on just 5V.

5. App Features

• SOS Activation: Via button press or loud voice

• Audio/Video Recording: For evidence

• GPS Tracking: Shared via SMS every 2 minutes

• Hidden Camera Detection: Ensures privacy in sensitive spaces

• Battery Monitoring: Sends location if battery runs low

6. Future Scope

• Wearable Integration: Miniaturized for use in jewelry, watches, bags

• Advanced Connectivity: Adds Wi-Fi, LoRa for rural/urban coverage

• AI Threat Detection: Learns and alerts users based on behavior patterns

• Longer Battery Life: Power-efficient upgrades for remote usability

Conclusion

Our primary goal of this project is to ensure every woman in our society feels safe and secure. According to the survey in India, 53% of working women are not feeling safe - Women working the night shift (Bangalore-56%, Chennai-28%, Hyderabad-35%, Mumbai-26%). Overall 86% of working women in India, women facing hurdles are high in Delhi, Mumbai, Hyderabad, Kolkata, and Pune compared to other places. Shakti can play a major role by providing women with a safe environment in all situations for example (detecting hidden cameras, physical threats, harassment, robbery, and stalking). By implementing real-time applications and a device, we can solve the problems to an extent. With further research and innovation, this project is used as a small wearable device like a watch, pendant, etc.
