An IOT Based Smart S.O.S. Wristband for Women Safety

Abstract

Violence against women in India is actually more present than it may appear at first glance, as many expressions of violence are not considered crimes, or may otherwise go unreported or undocumented due to certain Indian cultural values and beliefs. These reasons all contribute to India's Gender Inequality Index rating of 0.524 in 2017, putting it in the bottom 20% of ranked countries for that year. This paper introduces an IOT based smart wearable device which basically acts as a SOS signal for the women or children to contact their contemporaries on an immediately basis when in an emergency or dangerous situation. It is implemented using Raspberry Pi Zero, Raspberry Pi camera, GSM and GPS module along with an optional buzzer and buttons to activate the services. The basic operation of this device involves capturing an image of the culprit in the crime scene and sending the image along with the current location to the preferred contacts or police through the GSM module. This device also makes use of Haar Cascade algorithm which is a Machine learning image processing algorithm to enhance and highlight the image captured in the camera.
