Environment Setup

• Python 3.10 or higher

• Virtual Environment set-up

  1. Open a terminal in your project folder.
  2. Create a virtual environment (name it venv):

     python -m venv venv

  3. Activate the virtual environment:
     • Windows (Command Prompt):

       venv\Scripts\activate

     • Windows (PowerShell):

       .\venv\Scripts\Activate.ps1

  4. Install all required libraries:

     pip install -r requirements.txt

• Python Libraries
  Note: Can also be installed through pip -r install requirements.txt

  • python-dotenv
  • pyscard
  • pandas
  • pycryptodome
  • cryptography
  • numpy
  • pymongo
  • gmpy2
  • datetime
  • psutil

Running the Program

1. Ensure that all necessary packages are installed as mentioned previously, and that the program and its source codes are run in a virtual environment.
2. Make sure to adjust the IP address for the MongoDB_URI in the gui.py and db_manager.py source codes.
3. Update the .env file to match the system path where patient_data_headers.csv is located.
4. Run the program by using the following command:

   & .venv/Scripts/python.exe path/to/your/script.py

5. A GUI window will then appear, which allows the user to input the patient data and select an encryption algorithm, encrypt, and write to the NFC card, or decrypt the patient data written on the NFC card.
6. The output for both encryption and decryption will be displayed in the GUI and will also be saved in both a CSV file (metrics_log) and a .log file (metrics_result.log), as seen in the images below. Additionally, another CSV file (e.g., decrypted_aes for AES decryption) containing the decrypted data is produced during each decryption, depending on the algorithm used.
