Design and Development of a Woman Safety Device Prototype with Fingerprint Authentication

The growing need for personal safety, especially for women and children, has driven the development of Internet of Things-based wearable security devices. This paper presents the design and development of a security device equipped with GPS and GSM for real-time location tracking and emergency notification. The device also integrates fingerprint biometric authentication to ensure secure access and prevent unauthorized use. Additional features such as a camera and voice recorder enable the collection of audio-visual evidence that can be used as legal proof. The ASCON-128 encryption algorithm is used to protect user data privacy by securing the stored recordings, and the cryptographic keys are generated directly from biometric data. The testing showed that the device functions well in sending emergency notifications, tracking location, and recording the event as the evidence, both in the form of images and sound. The average location deviation of this prototype based on GPS sensor reached 5.43 meters and the furthest deviation reached 10.53 meters. The device's power consumption with a standby mode usage of 60.84 Wh and an active mode usage of 41.25 Wh. However, challenges in the decryption process required further improvement. Overall, this device offers an innovative solution to enhance the safety and legal protection of women in dangerous situations, with potential for further development.
