Security Solution for Internet Of Things(IOT)
EXISTING SYSTEM FOR
WOMEN SECURITY
Having this concern in
mind many developers have come up with creative applications. Some of such
applications are: Codes like *91# is used to provide emergency services, which
will alert police control. Free mobile application 'Help me on mobile' to
ensure safety of women was launched to assist those who need emergency .These
applications need a single click to do this task. But when a girl is in
trouble, there can be times that the girl is not capable of taking the phone
and pressing button.
A.SHE (Society Harnessing Equipment): It is a
garment embedded with an electronic device. This garment has an electric
circuit that can generate 3800kV which can help the victim to escape. In case
of multiple attacks it can send around 80 electric shocks [3].
B.ILA security: The co-founders of this
system, have designed three personal alarms that can shock and disorient
potential attackers and hence safegaurd the victim from perilous situations.
C.AESHS (Advanced Electronics System for
Human Safety) It is a device that helps track the location of the victim when
attacked using GPS facility.
D.VithU app: This is an emergency app
initiated by a popular Indian crime television series “Gumrah” aired on Channel
[V]. When the power button of the Smartphone is pressed twice consecutively, it
begins sending alert messages with a link of the location of the user every two
minutes to the contacts.
E.Smart Belt: This system is designed
with a portable device which resembles a normal belt. It consists of Arduino
Board, screaming alarm and pressure sensors. When the threshold of the pressure
sensor crosses, the device will be activated automatically. The screaming alarm
unit will be activated and send sirens asking help [4].
The main drawback of these applications and services
is that the initial action has to be triggered by the victim which often in
situation like these doesn’t happen. So the emphasis is to build a solution
that works autonomously in situations encountered.
The device communicates
with smart phone through a specially designed application that acts an
interface between the device and the phone. The data directed by the smart band
such as the pulse rate, temperature of the body along with the motion of the
body is continuously monitored by the application which is pre-installed in the
phone. In cases of abuse, the app directs the smart phone to perform the
following tasks:•Sends message to the family members along with the
co-ordinates. •Co-ordinates is sent to nearest police station requesting
immediate action. •Also sends information to people in near vicinity requesting
public attention. The app is programmed in such a way that it uses the GPS of
the smart phone to track the co-ordinates and monitor the movement for easy
track ability! The help message is sent to the family members and the nearest
police station through the GSM facility that is inbuilt in the phone.
The app also provides a
social platform where the people who have this particular app installed get the
messages instantaneously so that they too can contribute in justice being
delivered just in time. This feature is executed by using internet facilities
of the phone of the user. Control Unit collects information from smart wrist
unit and GPS receiver. GSM module will then send all these information from
control unit to base station. Wrist unit collects the data from human using
body temperature sensor, pulse rate senor and switches. RF module is used to
send data from wrist unit to the control unit.
A.PULSE RATE SENSOR:
Heart beat sensor gives digital output of heart beat. When heart beat detector
is working the led flashes for every heart beat. This digital output will be
connected to microcontroller directly to calculate the beats per minute (BPM)
rate. It works on the principle of light modulation of networked satellites and
are tracked to uplinks data for synchronization. The system uses four
frequencies in the L-band which ranges from 1.2 to 1.6 GHz.
B.GSM MODULE: GSM is
used to send data from control unit to base unit .We can use GSM 300 which
operates at frequency 900MHz. It has up link band of 890MHz to 915MHz and down
link Band of 935MHz to 960 MHz GSM takes advantages of both FDMA & TDMA. In
25MHz BW, 124 carriers are generated with channel spacing of 200 KHz (FDMA).
Each carrier is split into 8 time slots (TDMA). At any given instance of time
992 speech channels are made available in GSM 300 [5], [6].
C.DUAL TECHNOLOGY
MOTION SENSOR: A Motion Sensor is a device that detects moving objects. A motion
detector is often integrated as a component of a system that automatically
performs a task or alerts a user of motion in a specified area. Motion sensors
form a vital component of security. Many modern day motion sensors use
combinations of various technologies. While combining multiple sensing
technologies into one detector reduces false triggering, it does at the expense
of reduced detection probabilities and increased vulnerability factor [7].
D.BLE( Bluetooth Low
energy) BLE is designed to connect devices with low power consumption. A study
by Beacon software, Aislelabs, reported that peripherals, such as proximity
beacons, usually function for an year with a 1,000mAh coin cell battery. This
is possible due to the power efficiency of Bluetooth Smart protocol which only
transmits small packets as compared to Bluetooth Classic which was compatable
for audio and high bandwidth data [8].
E.TEMPERATURE SENSOR:
Human body temperature is of vital importance to maintain the health and
therefore it is necessary to monitor it regularly. We can measure the body
temperature using various temperature sensors. For instance, LM35 series are
precision integrated circuit sensors whose output voltage is linearly
proportional to the Celsius temperature. It operates linearly +10.0mV/°C scale
factor with 0.5°C accuracy.In emergency caes body temprature varies drastically
which can trigger module for rescue
