Abstract—Women Safety has always been an issue even in these modern times with so much advancement in technology. Women are not safe anywhere and are most vulnerable when travelling alone into lonely roads and deserted places. The hand-held safety devices for women require human intervention for activating the device. The work aims at designing an IoT based safety device that relies on providing security to women by fingerprint-based method of connectivity to thedevice and alerting nearby people and police when a woman is not safe. An unsafe situation is sensed by the device and then it will automatically automatically alert nearby people, parents and police. Additional features such as sending messages, audio recording, capturing the image of the situation are also part of the device.

They cannot leave their homes whenever of the day they cannot wear garments as indicated by their will and cannot go to work in harmony. There is a shame towards ladies that pulverizes their feelings of opportunity, yet besides, sabotages their trust and dreams. Because of the above factors, it is quite clear that in the country there is a struggling need for women's safety. This paper makes the strength of an insurance gadget that is planned simply to serve the reason for bestowing security to women so they never experience powerless while managing such social requesting circumstances. A propelled framework can be assembled that can help women when they are in harms way. In this paper, we are using Raspberry pi which is a low cost and can be portable and we using a temperature sensor, GSM, GPS, and Camera module. In our paper using three ways of connecting to the concerned authorities. For women safety and security purpose we made a device which is extremely compact and may be triggered utilizing sufferer just clicking the button and use of temperature and heart rate and voice data which integrated to the raspberry pi.

IoT is arrangement of related sensors, registering and advanced gadgets spread over the globe over the web which can convey among them to share and move data utilizing exceptional id which is relegated to each and each gadget, as UIDs (unique identifiers). With the developing of various business premises and social orders, the concentration to computerize these premises have expanded definitely. The application sends an alert by way of an SMS with the persons location to the configured group through the Global Positioning System (GPS) and the captured picture of the incident is stored in an external remote server. The application also makes a phone call to one of the managed contacts. It can

also be used in case of attempted molestation, accident, family emergency and chain snatching. This application can also be used by a person who witnesses the incident. The users are required to submit personal details such as email id and emergency contact numbers. The users can configure their own list of contacts including close relatives and friends.

effectively running in the province of Tamil Nadu, proposals on Self Help Group for future upgrade and a contextual investigation of Women Empowerment Cell.

D. G. Monisha et al [5]., Proposed a system which contain a location tracking mechanism, it works if the suffered person press a single click it sends a SOS message with current location to pre-set contact of every 2 minutes, if the person clicks a button double times then it records and sends SOS message and also it calls to the pre- set contact numbers when the person pressed a button for a longtime.


Our system serves as android phone-based technology to track the culprit with the geographical identification of the incident. The users are required to submit personal details such as email id and emergency contact numbers. The users can configure their own list of contacts including close relatives and friends. At the time of any critical incidents our application will save the women by intimating the nearby police station to rescue her and also it will give information to her family.
