The overall percentage of teenager abusements filed nowadays in the world is about 80%, out of which 74% are girl teenagers and the rest are boys. For every 40 seconds, a teenager goes missing in this world. Teenagers are the backbone of one\'s nation, if the future of teenagers was affected, it would impact the entire growth of that nation. Due to the abusements, the emotional and mental stability of the teenagers gets affected which in turn ruins their career and future. These innocent teenagers are not responsible for what happens to them. So, parents are responsible for taking care of their own teenagers. But, due to economic condition and aims to focus on their teenager\'s future and career, parents are forced to crave for money. Hence, it becomes difficult to cling on to their teenagers all the time. In our system, we provide an environment where this problem can be resolved in an efficient manner. It makes parents to easily monitor their teenagers in real time just like staying beside them as well as focusing on their own career without any manual intervention.
These Days parents are worried about their teenagers’s so they want a complete track of them and monitor them all the time, this is physically not possible. Basically, teenagers cannot complain about abusements which they face in their daily life to their parents. Teenagers can’t even realize what actually happens to them at their age. It is also difficult for parents to identify their teenagers are being abused. Since to prevent teenagers before being attacked, an autonomous real-time monitoring system is necessary for every teenager out there. In this system, the collected values from every sensor like temperature sensor, pulse rate detection sensor, metal detection sensor, and the location value from GPS are used to detect the status of the teenager and alerts the respective guardians using GSM accordingly.
II. LITERATURE SURVEY
A. RFID-based System for School Teenagers Transportation Safety Enhancement
This paper presents a system to monitor pick-up/drop-off of school teenagers to enhance the safety of teenagers during daily transportation from and to school. The system consists of two main units, a bus unit, and a school unit. The bus unit the system is used to detect when a teenager boards or leaves the bus. This information is communicated to the school unit that identifies which of the teenagers did not board or leave the bus and issues an alert message accordingly. The system has a developed web-based database-driven application that facilities its management and provides useful information about the teenagers to authorized personnel. A complete prototype of the proposed system was implemented and tested to validate the system functionality. The results show that the system is promising for daily transportation safety.
B. Design and Development of an IOT based wearable device for the Safety and Security of women and girl teenagers
The aim of this work is to develop a wearable device for the safety and protection of women and girls. This objective is achieved by the analysis of physiological signals in conjunction with body position. The physiological signals that are analyzed are galvanic skin resistance and body temperature. Body position is determined by acquiring raw accelerometer data from a triple axis accelerometer.
Acquisition of raw data is then followed by activity recognition which is a process of employing a specialized machine learning algorithm. Real-time monitoring of data is achieved by wirelessly sending sensor data to an open source Cloud Platform. Analysis of the data is done on MATLAB simultaneously. This device is programmed to continuously monitor the subject’s parameters and take action when any dangerous situation presents itself. It does so by detecting the change in the monitored signals, following which appropriate action is taken by means of sending notifications/alerts to designated individuals.
C. Teenager Safety Wearable Device
Parents need not have a smart mobile. Set of keywords are used to gain information from the kit. LOCATION keyword is used to obtain the location of the teenager. UV keyword is used to obtain the temperature of the surroundings. BUZZ keyword is used to turn on the buzzer which is fixed in that device. SOS is used to send a signal to the device.
D. Smart Intelligent System for Women and Teenager Security
A portable device which will have a pressure switch. As soon as an assailant is about to attack the person or when the person senses any insecurity from a stranger, he/she can then put pressure on the device by squeezing or compressing it. Instantly the pressure sensor senses this pressure and a conventional SMS, with the victim’s location will be sent to their parents/guardian cell phone numbers stored in the device while purchasing it, followed by a call. If the call is unanswered for a prolonged time, a call will be redirected to the police and the same message will be sent. Additionally, if the person crosses some area which is usually not accessed by the person then a message with the real-time location is sent to the parent/guardian's phone via conventional SMS.
III. EXISTING SYSTEM
Real-Time Teenager Abuse and Reporting System In the existing system, we use a voice recognition module in which the alert commands from the teenager are stored and kept for further reference. If the same teenager delivers the same command, it will compare with the alert command which was previously stored and sets an emergency level according to the alert command. The GSM has a SIM which is used to send an alert message or an alert call to the trusted peoples. GPS is used to track the live location and it is used when needed. The server will search the respective device ID from the database and search for respective contacts according to that device ID and helps in alerting the registered guardians.
The disadvantage of this project are,
The teenager could not produce the exact alert command during a panic condition.
The command produced may not match with the previously stored command.
This project requires manual intervention.
If the device moves, out of that boundary the server transfers an alert call by activating the GSM, to the user. The live location of the device will be updated in the server and pinged in the website for every few seconds. The server side coding was written in PHP and the controller side coding was written in Python.
The user will receive an alert call and after entering the login ID and password, they can check the live location through GPS, which was updated in the application. When giving boundary for the school unit, we can also maintain attendance by updating the entry and exit of the teenager, in and out, of school in the application.
We feed specific threshold values for sensors like temperature and pulse in which, if the device exceeds those threshold values or if the device gets exposed to abnormal condition then those values tend to be updated in the server. The server compares the currently obtained values with the coded threshold values, if they are beyond the threshold value, it generates an alert message through GSM. The alert messages are delivered to specified users in the form of SMS and the user can be able to login to the application to check the status and updated information.
After receiving the alert messages, if the user wants to visually check the status of the teenager, they are required to enter specific IP address of that camera for the first time before syncing and can be able to watch the live streaming videos which are updated to the server, for further uses they can directly view.
The microprocessor is used to control all these actions and the alert was done by checking for specific user of that device in the database.
One of the module in our project is temperature sensor which is used to detect the temperature of the teenager as well as the surrounding temperature. If there occurs any abnormal rise or fall in temperature in the body of the teenager or in the surrounding it will notify the user as per the coded time delay as shown in the picture. It will show the temperature and humidity values notifies the user based on the predefined value abnormal fall or rise scenarios.
We also have a web camera through which we can monitor the teenager lively through live video streaming whenever we get notified in abnormal cases. We have an IP address for the camera fitted with the kit and we are supposed to enter that IP address in our mobile application or web application through which we can see the live video streaming of what's happening around the teenager as shown in the picture. we can monitor the teenager 24/7 in real time through the help of this live streaming which makes parents feel that they are beside their teenagers ensuring teenagers's safety.
VII. FUTURE SCOPE
In our system, we automatically monitor the teenager in real time using Internet of Things, with the help of GPS, GSM, and Raspberry Pi. This system requires network connectivity, satellite communication, and high-speed data connection when we use web camera and GPS to lively monitor. It is difficult to monitor when there occurs any hindrance to satellite communication or any network issue. There also occurs time delay in video streaming through the server. Hence in the future, these issues can be overcome by using Zigbee concept or accessing the system without internet and using high-speed server transmission.
The word Future resembles the word Teenagers. As Dr. A.P.J Abdul Kalam’s words “Youngsters are the future pillars of one’s nation\", today\'s teenagers are tomorrow\'s youngsters, preserving their dreams and life for a better future is necessary. Therefore, each and every parent should take care of their own teenagers, without letting them to fall into the dark world of abusements, which entirely ruin them physically, mentally and emotionally destroying our future. Hence, considering the importance of our future, our project makes it easy for parents to track their teenagers and to visually monitor them on regular basis, which makes them ensure the safety of their teenagers and reduces the rate of incidents of teenager abuse.
