🚔 CyberDraft Engine – Automated Letter Generator for Cyber Crime Wing

📌 Overview

CyberDraft Engine is a desktop-based automation tool developed to assist law enforcement officers in generating formal investigation letters quickly and accurately.

The application reduces manual paperwork, minimizes human error, and significantly speeds up communication with Telecom Service Providers (TSPs), banks, and digital intermediaries.

Designed with usability and efficiency in mind, this system streamlines critical workflows involved in cybercrime investigations.

🎯 Objective

To build a secure, user-friendly GUI application that automates official letter generation for cybercrime investigations, improving operational efficiency for officers.

🚀 Key Features

🔐 Secure Authentication

Role-based login system (Admin & Officer)
Password hashing using bcrypt
Officer profile management

📄 Automated Letter Generation

Supports multiple investigation request types:

✅ Telecom Service Providers (Airtel, Jio, Vodafone, BSNL)

CAF Details
Call Detail Records (CDR)
IMEI Tracking
Aadhar-linked numbers
PoS requests

✅ Intermediary Platforms

WhatsApp
Google
Facebook
Instagram
Twitter

✅ Banking Requests

Bulk processing via Excel
Transaction and account detail extraction
Batch letter generation with progress tracking

🏗️ System Architecture

Frontend:

Python Tkinter (GUI)

Backend:

SQLite3 (Local Database)

Libraries Used:

python-docx → Word document generation
pandas → Excel data processing
bcrypt → Password security
tkcalendar → Date selection (optional)

🧠 How It Works

Officer logs into the system.
Creates or selects a case.
Chooses the request type (TSP / Bank / Intermediary).
Inputs required details.
The system dynamically fills pre-built templates.
A formatted .docx letter is generated instantly.
