I. INTRODUCTION

The problem of women's safety is a

significant issue in the world. With the

advent of technology, the aim is to find the

solution of the same using the concepts of

the Internet of Things and Cloud

Technology. Internet of things enables the

system to communicate with the Internet of

Things helps us interact with the natural

world and process real-world cues and

scenarios to get an output that assists

humans and other technologies [1]. Internet

of hings is a system of uniquely identifiable

components which communicate with each

other, share data, and allow users to

directly or indirectly interact with the

physical world. This technology can be used

to get location information and

communicate data collected [2]. Voice

recognition is a process that aims to

identify 'who' is speaking.

SpeakerVerification uses the process of

voice recognition to match the test input

with a pre-recorded sample for verification

or authentication. This falls under the

domain of biometrics. Cloud computing is

the availability of resources like data

storage and processing power, as per user

requirements sourced from a remote

location, over the internet. Cloud Storage

and processing has allowed us to store a

massive amount of data on a virtual storage

device. This reduces the memory

requirements in the wearable and makes it

cheaper as compared to using local storage.

The data needed is extracted from the cloud

storage according to specific requirements.

This also makes the data universally

accessible and reduces the risk of losing

data and evidence if the device is physically

harmed under any circumstances. Most of

the IoT based devices developed for women

safety use a mobile-based application to

activate the system. This, however, reduces

the device's utility in case of emergencies as

the usage of mobile phones in the presence

of an attacker might not be feasible. Our

system, on the other hand, does not use

any mobile interface. It is strictly a

hardware system that gets activated and

starts functioning on customizable voice

command. It is easier to activate and

provides better safety [3].

II. LITERATURE SURVEYS

Islam et al. [4] purposed "Design and

Implementation of Women Auspice System

by Utilizing GPS and GSM". In this system,

they used a GPS module, three

pushbuttons, PIC16F887 microcontroller.

GPS is used to get to the area of the client

quickly. Three press catches are executed

to characterize the kinds of a mishap

casualty is confronting.

When the client faces any issues wherever,

it can press any of these three catches. At

that point, the microcontroller will get it

and send an SMS to the particular

telephone number. The area of the client

will be constantly followed until the client

switch off the framework when saved.

What's more, to control the entire

framework they have utilized a PIC16F887A

microcontroller fueled by four AA batteries.

Muskan et al. [5] Implemented "Women

Safety Device Designed using IoT and

Machine Learning". This study is going to

design a device. For generating alarm, the

device is customized to learn the individual

pattern of temperature and heart rate and

determine the threshold when both

temperature and heart rate exceeds above

the threshold it automatically sends SMS

and location to the emergency contact

number to take action.

A. Priyadarshini et al. [6] suggested

"Women Empowerment towards developing

India". Women fortifying bases on

empowering every woman in the country to

make them selfruling in all perspectives as

a rule open, be careful about the rights and

cause them to get ready about physical

security. This paper centers around

portraying the issues that ladies are looking

in their daily life plans accessible for

Women Empowerment in India and Self-

Help Group which is effectively running in

the province of Tamil Nadu, proposals on

Self Help Group for future upgrade and a

contextual investigation of Women

Empowerment Cell.

Navya R Sogi [7] purposed "SMARISA: A

Raspberry Pi based Smart Ring for Women

Safety using IoT. They have actualized a

wearable gadget for ladies as a savvy ring

(SMARISA) and contain Raspberry Pi,

camera, signal and catch to initiate the

administrations and the gadget is very

compact. It can be enacted by tapping the

catch that will bring her present area and

catch the picture of aggressor employing

Raspberry pi camera and send to the crisis

contact number.Prof.

Sunil K Punjabi [8] designed the "Smart

Intelligent System for Women and Child

Security" A compact gadget with a weight

switch. At the point when an assailant is

going to ambush the women/kid or when

they recognize any shortcomings from an

increasingly unordinary, they would then

have the option to press the device by

pulverizing or pressing it. Promptly the

weight sensor identifies this weight and an

ordinary SMS, with the causality's zone

will be sent to their folks/watchman

telephone numbers set aside in the devices

while getting it. Followed by a call. If the

call is unanswered for a postponed time, a

call will be conveyed to the police, and SMS

will likewise be sent.

G C Harikiran et al. [9] Implemented "Smart

Security Solution for Women based on

Internet Of Things(IOT)" They proposed a

gadget that is the blending of two or three

contraptions, equipment fuses of a

wearable "savvy band" which continually

speaks with a sharp phone that has to get

section to the web. The product is

customized and stacked with all the

necessary data which fuses human conduct

and responses to unique conditions like

displeasure, dread, and pressure. This

creates a sign that is transmitted to the

phone. The product has got right of passage

to GPS and informing administrations

which are prearranged in any such way

that at whatever point it gets crisis signal, it

can deliver help demand along with the

spot co-ordinates to the nearest police

headquarters, family members and people

inside the near span who have utility

Nandita Viswanath et al. [10] purposed

"Smart Foot Device for Women Safety" This

shrewd gadget will be cut to the client's

footwear and can be enacted mindfully. On

tapping one foot behind the other multiple

times, an alarm is sent by methods for

Bluetooth low vitality correspondence to an

application on the causality's phone.

Adjusted to create an SMS searching for

help with the territory of gadget associated.

III. RELATED WORK:

Raspberry Pi

Raspberry Pi (pa ltd) is a series of tiny

single-board computers (SBCs) that have

been created in the UK and developed in

partnership with Broadcom by the

Raspberry Pi Foundation. Initially, the

Raspberry Pi initiative aimed at promoting

fundamental education in schools and poor

nations. The first model was more popular

than expected, selling for applications such

as robotics beyond its intended market. It is

extensively utilised, because to its cheap

cost, flexibility and open design, in various

sectors, for example for weather monitoring.

The HDMI and USB devices are often used

by computer and electrical enthusiasts.

Following the introduction of the second

board type, the Raspberry Pi Foundation

created a separate company, Raspberry Pi

Trading, installing Eben Upton as its CEO,

in charge of technological development. The

Foundation has been rededicated to

promote basic computer instruction in

schools and underdeveloped nations as an

educational charity

.

Sold units of the Raspberry Pi

One of the best-selling British computers is

the Raspberry Pi. More than forty million

boards were sold as of May 2021. Most Pis

is manufactured at a Sony plant in

Pencoed, Wales, while some are

manufactured in China and Japan.

DHT11

The DHT11 is a key, high-cost digital

sensor for temperature and moisture. It

utilises a capacitive moisture sensor and a

thermistor to monitor the environment and

spreads a digital signal to the data pin (no

analogue input pins needed). It is

reasonably easy to operate, but needs

precise scheduling for data collection. The

only major disadvantage to this sensor is

that you can only get fresh data once every

2 seconds, thus sensor values may be up to

2 seconds outdated when utilising the

library.

Fig 2: DHT11

Heart Beat Sensor -BH1792GLC

A sensor for optical heart rate detects pulse

waves that alter the volume of the blood

vessel as the heart pumps blood. Pulse

waves are detected using an optical sensor

and green LED to measure volume

variation. Optimizing an optical filter for

pulse wave detection in the sensor block

reduces environmental light influences

such as red and infrarot rays.

Fig 3 Heart Beat Sensor -BH1792GLC

This makes it possible to get high-quality pulse signals, even outside. Furthermore, using the optical sensor technology developed over many years, ROHM increased the sensitivity of the sensor block considerably. Supporting low-brightness VF LEDs enables a low optical heart rate monitoring system to be achieved without

the requirement for additional circuits (i.e., boost circuit). This leads to longer wearables with limited battery capacity.

Pi Camera

The Raspberry Pi Camera V2 is an 8

megapixel high-quality Raspberry Pi image

sensor Sony IMX219 with a fixed focus

lens. The camera is capable of 3280 x 2464

pixel static pictures with images of

1080p30, 720p60 and 640x480p90.

IV. PROPOSED SYSTEM

The primary purpose of this article is the safety and safety of women using raspberry pi. Python programming is employed for this purpose. The raspberry pi has a temperature sensor, heart beat sensor, GPS and camera module incorporated. If a lady is in danger, the alarm will automatically send the authorities concerned manually. SMS notice would be sent to the authorities involved. In addition, the use of voice information will assist women at risk. And not in such circumstance to click the button, if you use it, to tell the guardian to send an SMS alert and the taken picture.

Architecture of the system

The design of the system includes a Power Supply, Temperature Sensor, Heart Beat Sensor, Raspberry pi module, GPS, Camera, Voice and two input buttons. Figure 5 illustrates the architectural chart for women's safety gadget, which includes raspberry pi is a low cost single board computer for connecting the pi raspberry camera and a button for the transmission of a message to the police and chosen individuals. a pi camera m that clicks the criminal picture and also uses GPS to transmit women's present position.

Fig 5: Block Diagram of Women Safety System

Block Female Security System Diagram Here we use the raspberry pi temperature sensor and beat sensor. The typical human body temperature is 37oC, and the healthy person's medium heartbeat rate is 60-100 minutes. When the ladies are at risk, their body temperature and heartbeat will rise if both circumstances are over the threshold level, which means that a message is sent to the family/police/friends automatically. If we notice anything going strangely, in this situation it also surpasses the threshold above, we utilise another button to convey the message that I am secure. If we use two buttons, in certain instances it sometimes doesn't work implies that we also use a button if a woman is in danger; she pushes a button, and the text messages, picture and place will be sent to the authorities involved. If a woman can't push the button if above two circumstances we don't use voice data which is the main benefit for women in danger. When she can't push button, she asks assistance, the message will send to the authorities concerned, this is one of the major benefits of our paper.

A Raspberry Pi Board, temperature and heartbeat sensors, pi camera, GPS, panic button, and nodemcu controller for interface with heart rate and gps are the

prototype models of the women's safety system. A smart raspberry pi is loaded with a micro USB loader. A 12 volt power source is supplied. Where sensors constantly measure temperature and heart rate. We use three potential circumstances in our initiative to assist women in danger.

We use a temperature sensor and a beat sensor combined with the raspberry pi. The typical human body temperature is 37oC, and the average healthy person's heartbeat rate is 60-100/min. When women are in danger, their body temperature and heartbeat rates rise if the two circumstances reach the threshold level, which indicates that the message is delivered to the family/police/friends automatically.

If we notice anything going strangely, in this situation it also surpasses the threshold above, we utilise another button to convey the message that I am secure. If we use two buttons, the above condition sometimes does not work, it also implies that when women are in danger, we will use a button and then push the SMS, picture and location to send them to the authorities concerned.

Expect this lady is not able to push the button if no above two criteria are satisfied then we use voice data, which is the main benefit for women when she is in danger if she cannot push the button and tell them that the message will be sent to the authorities involved.

Conclusion

The existing procedures are not strong enough to prevent the criminalization of women. The primary aim of the system is quick and cheap cost. This document will enable women to quickly identify with the authorities in question when they are in risk. The method utilised consists of GPS tracking, SMS alerts, picture capture and even usage of audio data. The alert is issued manually as well as automatically. This model may be further developed to create a wearable device. The design may be compacter and lighter to be readily portable and user-friendly.
