Detailed Description of the Invention:
In the digital era, data security is a matter of utmost concern. The increasing use of computers and the internet has made it easier for malicious actors to gain unauthorized access to sensitive information. Among the primary methods used by cybercriminals is infecting computers with malware, which can lead to severe consequences for individuals and organizations.
To address these pressing challenges, the present invention "File Defender" is developed which is a comprehensive system that provides a user-friendly interface to encrypt files, decrypt previously encrypted files, and scan files for malware detection. The tool combines encryption technology, specifically AES-256 (Advanced Encryption Standard), with a simple password-based system to ensure files are securely protected. Furthermore, authorized users can easily decrypt files using the provided password.
Figure 1 shows the flow of data and control in the “File Defender” tool. When the system executes, it asks for the files or directory to encrypt, decrypt, or scan for malware signature. The above DFD shows the four modules of the “File Defender” program as separate processes. The GUI is connected to the “File Defender” module, which is the main module and is responsible for coordinating the different processes.
The Encrypt module is responsible for encrypting files in a directory(s) recursively and storing the encryption key in a text file (key.txt). The Decrypt module uses the encryption key to decrypt all the files. The Scanner module is responsible for scanning a single file or all files in given folders or directories recursively to detect files that have malware signatures. It matches each file with the malware signatures file in the "signatures" folder of the program. The Key.txt file is used by the Encrypt and Decrypt modules to encrypt and decrypt files, respectively. The Malware Signatures file is used by the Scanner module to identify files with malware signatures.
Figure 2 shows the functionalities of “File Defender” tool and shows the four modules of the “File Defender” tool as separate processes. The encryption and decryption is done by Encrypt and Decrypt modules respectively. The flowchart shows the flow of data and control in the “File Defender” program. The program starts when the user launches it. The GUI is displayed, and the user interacts with the program by selecting the files or directory to encrypt, decrypt, or scan for malware signature. The main module is responsible for coordinating the different processes.
The Encrypt module encrypts the selected files or directory and stores the encryption key in a text file (key.txt). The Decrypt module uses the encryption key to decrypt the files. The Scanner module scans the selected files for malware signatures by comparing them with the malware signatures in the “signatures” folder. The Key.txt file is used by the Encrypt and Decrypt modules to encrypt and decrypt files, respectively. The program outputs the results to the user. The program ends when the user exits it.
The “File Defender” program is divided into several modules, each of which performs a specific function. Here is a brief description of each module and its functionality:
Encryption Module - This module encrypts files within a given folder or a directory browsed by a user. The encryption uses AES-256 encryption and the encryption key is generated using a user-defined password.
Decryption Module - This module decrypts previously encrypted files within a folder or directory. The user must provide the correct password used during encryption to successfully decrypt the files within their folder or directory.
Malware Scanning Module - This module scans a single file or a directory. In fact, the user browses the file or directory to scan. Then the program after running tells whether the browsed file or files inside of the browsed folder or directory contain malware signature, or string or not.
Graphical User Interface (GUI) Module – This module provides an interface for interacting easily with the program. It allows the user to browse a single folder or directory for file encryption or decryption, as well as file or directory malware scanning. It contains an output clear button and a scroll up and scrolls down button. The GUI was implemented using the tkinter library, while the program's functionalities were implemented as functions that were called by the GUI's event handlers.
The software requirements for running the system will be specified in Table 1, outlining the necessary components for optimal performance.

The software system described in this document is designed to operate on the Windows operating system. It is primarily intended for developers and requires the following Python modules for installation: tkinter, os, pycrypto, hashlib, yara, argparse, crypto.cipher, datetime, os.urandom (16), termcolor, configparser, json, base64, PyCryptodome, win32crypt, locale, platform, pathlib, itertools, subprocess, typing, request, reportlab.
The programming language used for the development of this software is Python 3. The system incorporates multiple techniques for enhancing its functionality, including Yara 4-based rules for pattern matching, known virus signatures-based and strings-based techniques for detecting malicious content, and encryption and decryption techniques to ensure data security.
Developers can efficiently work on the software using the Visual Studio Code (VScode) development environment.
System Flow:
When the program is launched, the user is presented with a GUI window that contains the following elements:
• A label displaying the name of the program.
• A menu bar containing drop down menu such as “Cryptography”, “Malware Scanner”. Each drop down menu has options. “Cryptography” submenu is “Browse Directory to Encryption” and “Browse Directory to Decryption”, while Malware Scanner submenu are “Browse File” to Scan, “Browse Folder to Scan”.
• A Listbox in the center displaying the output or result of the program.
• A button to clear the output of the listbox.
• A label that displays the report when encryption, decryption or malware scanning is completed.
• A label to track use chose or operation. As an example, if user click on “Cryptography” menu and chose “Browse Directory to Encrypt”, and then cancel it without selected the directory to encrypt. The program notifies him on the Listbox that he doesn’t Browse the directory to encrypt. The same goes for Decryption, malware scan and other case.
• Message box that displays notification when any operation completed.
When the user clicks on the encryption or decryption options in the menu bar, the program prompts the user to select the folder or directory to encrypt/decrypt. After selecting, the program generates a new encryption key using the os.urandom() function, saves the key to a file, and encrypts folder or directory content using the generated key. While if the decryption option is selected, the program prompts the user to select the folder or directory to decrypt. After that, it asks user to browse the key file used for encryption and then decrypts the chosen folder or directory using the selected key file.
To scan file, user has two options, scan single file or scan given folder or directory. When the user clicks on Browse scan File in the menu bar, the program prompts the user to select the file to scan for malware. While when the user clicks on browse scan folder in the menu bar, the program prompts the user to select the folder to scan for malware. The program then scans the selected file or folder for malware by comparing the file's hash with the hashes of known malware signatures stored in the "signatures" folder. If a match is found, the program adds the file to the list of infected files and displays the report on the screen.
The program's output is displayed in the listbox. Each operation performed by the program is logged in the listbox along with a timestamp. The program also colorizes the output using the termcolor module to make it easier for the user to read. Finally, the program includes a button to clear the output of the listbox, as well as a label that displays the report when malware scanning is completed.
