ABSTRACT
The Online Crime Reporting System is a web-based application developed to simplify and digitize the process of registering and managing crime complaints. In the traditional system, citizens are required to visit police stations physically to file complaints, which can be time-consuming and inconvenient. This project provides an online platform that allows users to report crimes, track complaint status, and communicate with authorities from anywhere using the internet.
The application is developed using Python Flask for backend processing and SQLite for database management, with HTML, CSS, and Bootstrap used to design a responsive and user-friendly interface. The system follows a role-based access control model involving three types of users: Citizens (Users), Officers, and Administrators. Citizens can register, log in, submit complaints, and track their case updates. Officers can view assigned complaints, add investigation notes, and update complaint statuses. Administrators manage the overall system by monitoring complaints, assigning officers, and managing registered users.
Security is ensured through features such as password hashing for secure storage of credentials, and session-based authentication to restrict unauthorized access. The system maintains all complaint records digitally, eliminating paperwork and improving accuracy, transparency, and accountability in case handling.
Overall, the Online Crime Reporting System offers a practical and efficient solution for modernizing crime reporting procedures while strengthening communication between the public and law enforcement authorities.

INTRODUCTION
Crime reporting plays a crucial role in maintaining safety and law enforcement efficiency in society. Traditionally, the process of reporting crimes requires individuals to visit police stations and submit written complaints in person. While this system has been operational for decades, it creates several challenges for both citizens and authorities. Victims or witnesses often face difficulties such as long waiting times, travel inconvenience, fear of facing authorities, or lack of time to report incidents promptly. These factors may discourage people from reporting crimes, leading to delays in investigations and reduced crime documentation.
Manual complaint registration workflows also present internal challenges within police departments. Paper-based record keeping is prone to data loss, misplacement, duplication, and errors. Searching, updating, or sharing case information becomes slow and inefficient, which affects case monitoring and decision-making. Administrative tracking of complaint progress is also difficult when using traditional documentation methods. These issues highlight the need for a modern, digitized platform capable of simplifying communication between citizens and law enforcement agencies.
The Online Crime Reporting System is designed to overcome these limitations by providing a secure and accessible web-based platform that enables digital crime reporting and case management. The system allows citizens to register accounts, submit crime complaints online, and track progress without visiting a police station. Each complaint is recorded in a centralized database, enabling officers to efficiently review assigned cases and update investigation status digitally. Administrators supervise the entire workflow, assign officers to cases, manage user accounts, and view overall complaint statistics.
The application is built using Python Flask as the backend framework and SQLite as the database system for handling structured data related to users, complaints, and investigation updates. The frontend is created using HTML, CSS, and Bootstrap, ensuring a responsive interface that works across multiple devices. The system emphasizes data security through password encryption techniques and session-based authentication to prevent unauthorized access. Role-based permission controls ensure that users only access features relevant to their roles, maintaining system integrity and confidentiality.
This project demonstrates how modern web technologies can transform traditional public service systems into efficient digital platforms. By reducing paperwork, minimizing reporting delays, enabling transparent complaint tracking, and improving coordination between citizens and law enforcement officers, the Online Crime Reporting System contributes toward streamlined administration and better public service delivery. The application serves as both an academic demonstration of full-stack web development and a practical model for implementing digital governance systems in real-world environments.
