Abstract :
The rising occurrence of theft in public areas like buses, trains has heightened the demand for low-cost, portable, and effective personal security devices. Bags, which tend to be used to hold valuable items, are particularly exposed to theft because they are easily accessible and heavily dependent on simple locking devices like padlocks and zippers. These conventional methods have only passive protection and can easily be broken or manipulated. To cope with this increasing issue, this paper proposes the design and implementation of an alarm-based Anti-Theft bag security system with active and real-time reaction to unauthorized entry. The new system incorporates hardware and software elements in order to guarantee real-time detection, deterrence, and control. It is constructed with an ESP32 microcontroller, magnetic door sensor, active buzzer, and rechargeable battery and remote monitoring and control through the Blynk IoT platform.
In a closed position of the bag, the magnetic sensor stays in contact, representing an authorized state. If an unauthorised opening is attempted on the bag, the sensor can sense the detaching of its magnetic contact and alert the ESP32 to activate the buzzer. The active buzzer generates an audible alarm that immediately alerts the owner and the people around, thus deterring theft. The alarm is persistent until the user turns it off manually through the Blynk mobile app, sending a "Stop" command remotely. This combination of hardware and IoT software offers an easy-to-use interface for both control and monitoring in real time. Use of a rechargeable battery by the system guarantees portability and seamless functionality, hence its application in mobile settings like public transport and travel scenarios.
The suggested system was field-tested in various real-life scenarios to assess its performance. Findings indicated an instantaneous response upon detection of intruder access. The system showed good deterrence power, with the alarm serving to draw attention and discourage attempts at stealing. Users could remotely switch off the alarm via the Blynk app, adding flexibility and ease of use. The magnet sensor proved to be dependable by reliably detecting when bags are opened without triggering false alarms during normal handling, thus verifying system stability. In addition, the design was energy-efficient and utilized little power in idle mode and only moderate power when alarm mode was on.
The combination of ESP32's Wi-Fi and Bluetooth support with IoT-based mobile control has turned an ordinary bag into a smart, interactive, and responsive security system. Hardware-software integration, real
time generation of alerts, and human-centric control mechanisms are highlighted in this research, advancing portable security technology. The results confirm the Anticipated Anti-Theft bag as a viable, reliable, and costeffective solution that complements personal safety in crowded places. Potential future enhancements could incorporate offline deactivate functionality. In general, the system effectively illustrates how IoT and embedded systems can be used to develop intelligent, proactive anti-theft devices that balance efficiency, usability, and portability for daily protection.
