ABSTRACT

With the advancement of chat applications over internet, ones messages can be reached all over the world which means it can be used to influence younger generation in both good and bad ways. Although, these chat applications have many advantages like communication can happen anywhere, anytime but it also has disadvantages like terrorist activists can also convey their messages through these chat applications to make other people all kinds of terrorist, cybercrime, etc. So, we propose a chat application system that monitors the various chats going on and detect the suspicious chats too. The server handles all the chat process and scans it for any suspicious words. If there are suspicious words, then an alert is provided to admin and admin can detect that particular chat. The chat history is being saved in the database from which admin will block any suspicious message. Only admin have the authority to access the database. Therefore, our chat application system is mainly to provide secure communication and reduce illegal activities.

CHAPTER ONE

INTRODUCTION

1.1Introduction

Chat refers to the process of communicating, interacting and/or exchanging messages over the Internet. It involves two or more individuals that communicate through a chat-enabled service or software. Chat may be delivered through text, verbal, communication. Chat is also known as chatting, online chat or Internet chat (Brindha et al 2019).

Chat applications allow all kinds of communication including threatening message and illegal activities (Shakil 2012). For the purpose of reducing such illegal activities, this research will attempt to propose a system called Active Chat Monitoring and Suspicious Chat Detection using tools like Eclipse, MySql and Java Language. In this system, many clients who are also known as users can communicate with each other and their chats can be monitored in the server. The suspicious keywords are stored in the database and only admin has the authority to access that database in order to insert new keywords and alter data if required. The server analyzes plain text and if any suspicious words are found, then it alerts admin. The admin, on getting the notification will delete the particular user so that he/she cannot chat again.

In our active chat monitoring and suspicious chat detection system, user can only send and receive messages to and from the other users and cannot monitor like the admin. Without the knowledge of users the admin is able to see the live chat of users and is responsible for watching out the suspicious conversation between users. We are using Port number to connect two users to start the chat. The system was designed in such a way that admin and users are mandatory to register in this system first in order to access the system. So, admin should have valid account to monitor the chat and same goes to users to chat with other registered users.

Nowadays with development and advancement of new technology especially focusing on chat applications, it connects all the people around the world. It is one of the important technologies to unify the society together and to deliver messages within seconds. But with such kind of advantages and benefits, there comes the disadvantages of it too.

With increasing use of chat application, the illegal activities have also risen drastically. Criminals and all sort of terrorist take advantage of this application to preach their messages and influence the younger generation to do illegal things. And also sending threatening messages and taunting people through chat has became common because of the fact that the other side user will not be able to see the sender’s face and all.

So, it is very important to have chat monitoring and detecting system along with the chat application as chat monitoring and detecting system will detect criminal behind the screen. And also people will be aware of such systems and will withdraw themselves from doing illegal things and could make good use of their time.

Thus, our proposed system will be able to make the society more stable by reducing the number of criminals and it also assures the user security and protection. The system will not only detect the suspicious users but also have the ability to delete them so that they cannot join the chat from next time and the other users will not be influenced by the suspicious users. And also there is a least chance of getting threatening messages and thus users may feel secure and relieve.

1.2Problem Statement

The Active Chat Monitoring and Suspicious Chat Detection System can detect only plain text and cannot be used for any voice chat and videos shared between the users. It cannot detect many suspicious words online hence it is vulnerable for cyber frauds. But if the framework proposed at server side is integrated, there will be significant reduction in cyber crime. The system will track that word even if the statement is not mentioned in that way. The proposed system first detects the suspicious activities when suspicious user sends some suspicious message to another user and then deletes that message instead of deleting it before delivering the message.

1.3  Objectives

Active chat monitoring and suspicious chat detection is a chat system where suspicious users are identified by determining the keywords used by him/her. The main purpose of this project is to develop software that can be used to find a system that identifies deception in messages through communication. The system is designed in a way that the users can easily interact with the system with minimum knowledge to browse the internet. It detects what kinds of information are being passed from the users and can detect their whole conversation without their notice. It can be used along with most widely used social sites like face book, twitter, etc. to provide security against cyber crime. By the use of this system, one can be saved from involving in illegal activities and from being a cyber victim.

1.4 Scope of the Study

Our system will detect only online plain text from the discussion forum and will divide or classify the text into different category and it will decide whether the posts are legal or illegal. In our proposed system, the admin that is the server may not always watch the chat. So, in order to prevent illegal or suspicious chatting, admin sets the keywords as suspicious words which will be deleted as an alert will be sent to the admin.
