EFFICIENT TRACKING FOR WOMEN SAFETY AND SECURITY USING IOT

: Women play vital roles in our society from their birth to the end of life. In the past few years, crime against women has increased to a great extent. According to the survey it is found that 84 per cent of the women who experienced harassment were in the age group of 25 to 35 years, who ar e mostly full-time workers and students. Most of the women also don’t conc entrate on th eir health due to th eir busy schedule. Women safety and security is a serious and biggest social issue and most importantly hurting the half population of the country in all aspects which needs to be solved urgently . Sin ce no one can respond ap tly in critical situations, we propose a smart intelligen t device which automatically senses information and helps women in “Every single step of life”. The device is the integration of multiple devices comprises of a wearable smart-band and a secret webcam connected via Blu etooth which continuously tracks the information and communicates wi th smart phones that has access to the internet. The application is programmed and embedded in such a way that tracks information of the women such as call log, messages, movement, p ulse measurement, blood ox ygen levels, heart beat rating and r ecords continuously in the internet. When SOS present in smart band is pressed continuously it automatically generates signals to the predefined smart phones and nearest police station along with location coordinates and the secret webcam in the locket captures the culprit photo which is directly uploaded to the server.


INTRODUCTION
Today, in the current global scenari o, Women were faci ng lot of challenges. Even after playing her all the roles and all the job timely in efficient manner in the modern society, she is weak because men are still strongest gender of the society. In th e last few years, crime ag ainst women in Delh i h as increased to a great extent. Some o f t he most c ommon crimes agains t wom en are rape, dowry deaths, se xual harassment at hom e or wo rk place, kidnapping and abduction, cru elty b y h usband, relatives, assau lt o n a woman, and sex trafficking. According to the statistics, it is found t hat e very t wo out of t hree women have s uffered around two to five times sexual harassment in the last year. By th e su rvey o f D elhi gover nment's Women an d Ch ild Development Depa rtment, aro und 80% o f t he w omen i n national capital have fear regarding their safety. Today girls were not allowed to m ove freel y eve n in t he streets due to security reasons. Day b y day the w omen h arassment is increasing. As of now we a lone ca n't c hange t he s ociety totally but we can increase the security of women by using modern technology. Nowadays though the re are many apps and devices evolved for w omen safet y vi a sm art phone w hich c an be act ivated only by a t ouch or one cl ick or sh ake t he mobile. It i s n ot possible t o car ry mobiles i n our ha nd i n al l ci rcumstances and it is not possible to make a call or click on it or shake it, so here we introduced a new technique via smart watches. This paper describes abo ut a sm art an d efficien t in telligent security system fo r women wh ich is the in tegration of multiple d evices c omprises of a w earable s mart-band an d locket c onnected vi a B luetooth which c ontinuously t racks the inform ation and c ommunicates with s mart phones t hat has access to the internet. T he application is programm ed and em bedded i n such a wa y that tracks inform ation and records co ntinuously in th e in ternet and when SOS prese nt in smart band is pressed it automatically generates signals to the predefined smart phones and nearest police station along with location coordinates. The locket comprises of we bcam which captures the culprit photo and tracked in the internet. The system i s in tegrated with a device wh ich helps in tracking heal th i nformation. It measures pul se a nd blood oxygen l evels and m onitors heart beat . It pr ovides detailed information ab out frequ ency, d uration, in tensity, a nd patterns of movement to d etermine yo ur step s taken , distance travelled, calories burned, and sleep quality. The 3axis im plementation allows the accelerom eter to m easure your motion in any way that you move. This device guides the wo men in m aintaining h er h ealth during abn ormal condition or pregnancy.

EXISTING SYSTEM
The existing systems surveyed are mentioned below: a) System designed as apps for android smartphones  In paper [1 ] th e v oice reco gnizing mo dule will recognize the user a nd activ ates the app e ven i f the mobile keypad is lo cked. The GPS in m obile will read the latitude and longitude to trace the exact location of the user a nd sends the alert message inc luding t he location t o re gistered co ntact num bers. The a udio recording m odule rec ords t he con versation f or evidences. Al so user ca n s elect contact number t o make a call through voice based contact list.  In pap er [3] a sin gle click in th e mobile a pp it first make a call to the first regi stered contact number and sends the alert message to all the registered c ontact numbers al ong wi th t he l ocation c ontinuously f or every 5 minutes until the stop button is click ed in the application.
 VithU is a popular app for women safety wh ich is activated when the user press the Power button present in smartphone twice. It sends an alert message to user's emergency contacts every two minutes.  Raksha t his ap p i s act ivated whe n t he button t apped, immediately s ends the use r's location to specified contacts. If t he ap p i s swi tched off or n ot wo rking, when the user press volume button for three seconds it can send alerts using SOS functionality.  Stay Secure a pp ca n be activated by pressing t he Power bu tton five tim es an d au tomatically send s an alert to use r's e mergency c ontacts. It also has a free SOS SM S feature w hich ca n sen d a t ext t o fi ve of user's saved c ontacts within five minutes. Stay Secure also allows the user's saved contacts to keep a track of her location and can work without data connectivity.  Shake2Safety app is activat ed when t he user s hake Smartphone or pre ss t he p ower button f our t imes t o send an SOS text or call to the pre-registered numbers. It works even when there's no internet connection. b) System designed as devices  In paper [ 2] t he sensor in t he watch g ets activ ated when the ta rgeted hea rt rat e for the targeted tim e period is achieved and produces alarm sound to make the n earby people atten tion. It au tomatically calls th e registered c ontacts and se nds the user's location through message.  In paper [4] when t he use r pres s t he c ontrol b utton present in smart watch it immediately sends senses the voice command and sends it to the nearest police with the curre nt l ocation. It also co ntains a sh ock mechanism to produce elec tric sh ock i n emergency situations to deter the attacker.

PROPOSED SYSTEM:
Base on t he critical analysis and t he re quirement of safet y functionality the m odules are sel ected as shown in figure 1.
The pr oposed syste m mainly consists of t wo weara ble devices.

Wrist watch tracking device
This syste m c omprises of various features listed below.  Device with SIM enabled  GPS,BLUETOOTH &WIFI  Two way talk  Long standby  Intelligent power saving  live tracking,  Emergency call (another form of SOS)  GSM 900/1800/1900 with GPR  45X35x13.5mm  GEOFENCE The smart watch is capable of storing few contact numbers. The up a nd d own b uttons on right si de o f t he watch is used to select contact and m ake a call. It ha s capability to receive a call as well. The re are two m ore buttons on the left side of the watch, one is SOS button and other i s p ower-off b utton. The device is activated when SOS bu tton is click ed for t wo second s. I t is pr ogrammed that whe n the device is activ ated, it immed iately sends the alert messages like " I am in da nger, pleas e hel p me" with long beep sound with high volume at the receiver side e ven it is in silent profile along with location using GPRS.
The device is also em bedded wit h live t racking chip which sen ses th e pulse rate, h eart b eat, calo ries burn t and bl ood oxygen l evels o f the us er. Normally the sm art watch always keeps tracki ng the information of user like day t o day call l og (i .e out going a nd i ncoming cal l information), messages, movement (where the user is going specifically wi th t ime), bl ood oxygen l evels, p ulse measurement, heart beat rate , calories burnt for eve ry one hour d epends o n th e setting . Th e 3-ax is i mplementation allows the accelerometer to measure the motion in any way that th e u ser moves. All th ese in formation is sto red in the server thr ough in ternet. When t he user is in abn ormal condition, th e d evice imme diately n otifies th e registered contact numbers with the message "The user is in abnormal situation, please con sult d octor i mmediately" al ong with location of the user.
The device al so has a feature " GEO FE NCE", which imm ediately a lerts receive r (the registered contacts) when th e user m oves ou t o f sp ecified lo cation with a message "Out of boundary, Please look over".

2) Device with Camera which can be used as locket
This device consists of the following features  Bluetooth  Camera with 0.3 Mega Pixel (spy camera)  Rechargeable battery  This de vice ha s t wo buttons one i s power off an d other is to activate. When the device gets activated the cam era captures the a ttacker's picture and records in the server. These pictures will be used as the evidence.  It detects the infrare d rays com ing from every hidden cam eras placed in changi ng rooms, hotels room etc., in s uch cases it tra ces the location using GPS m odule a nd se nd t he notification t o t he use r about unsafe place. We can programm e according to the user decisions to register the complaint base on notification.
To m ake t he proposed system work , both the sm art wat ch and loc ket ca mera must be charged a nd turne d on.The following st eps m ust be d one before t he use r using t he system.
Step 1: Register contact numbers in the smart watch Step 2: Set the time duration for tracking the information, so that for every mentioned time the information is upd ated in the server.
Step 3: B luetooth m ust be e nabled i n b oth t he devices(i.e watch and locket) This System can be used in different levels for a women. If the user enables Health Tracker, the system tracks the pulse rat e, hea rtbeat, calories burnt and bl ood o xygen levels of the women for every time duration depends on the setting of the user. This information will be stored in the server so that she or her family members who know the URL a ddress can view t he data. When the readi ng of ei ther pulse or heart beat or cal ories burnt o r bl ood oxygen levels are not in normal condition (exceeding or falling below th e lim it), immed iately th e sy stem sen ds alert message "SHE IS IN ABNORMAL CONDITION, CONSULT DOCTOR" t o the re gistered numbers with long beep sound at the receiver side. This system will also h elp wo men to guid e how much she have to walk. It informs the women to "walk" if she sit for lon g time and also if sh e walk (or jog) for more ti me it i nforms th e number o f calories bu rnt and suggest to "stop walk". This system helps the women to make herself fit and mainly during her pregnancy.

b) Working of safety device as GeoFence
The GPS i n Smart wat ch t racks t he m ovement of t he women an d i s use d t o know t he s peed o f m ovement with th e help o f rate o f change in lat itudes an d longitudes. F or every t ime duration de pends on t he setting th e inform ation is track ed an d sav ed i n the server. When the women moves out of the area (which can be speci fied) it immediately notifies with message to the re gistered num bers "SHE IS OUT OF BOUNDARY, TA KE CA RE". Esp ecially this GeoFence can b e u sed in child ren (g irls) so that wh en the ch ild (g irl) moves ou t of specific area. This can be viewed at t he URL as the i nformation is stored i n the server. c) Working of safety device when women in vulnerable attack.
When the women face with an y vulnerable attacks, the only thing she has to do is pressing SOS button for two seconds. Immediately the device gets act ivated a nd sends the alert messages like " I a m in dange r, please help me" with long beep sound with high volume at the receiver side even it is in silent profile, along with location using GPRS. Th is syste m wo rks even in th e absence of internet connectivity. The hidden camera in the loc ket like device is also gets activated whe n SOS is clicked and ca ptures the attacker's pictures. Th is info rmation will b e also gets stored in the server so that these pictures ca n be helpful for evidences.

CONCLUSION
This Efficien t, Sm art an d In telligent device really h elps women in "Every single step of life". The women need not hold th e device lik e smart ph ones. Th e only th ing t o do is enabling before they need. When the device gets activated it stores every information of women in the server and notifies the police and their family members (i.e registered numbers) when required.This system act as super fancy guard for women at a nytime and a nywhere when they wea r. So that women can c ome out freely with out an y ob stacles to reach their goals and future endeavours.
