Program Code – Python for Secure Video Streaming

import os
import socket
import threading
from cryptography.fernet import Fernet

# Generate a key for encryption
def generate_key():
    return Fernet.generate_key()

# Encrypt video data
def encrypt_data(key, data):
    cipher = Fernet(key)
    encrypted_data = cipher.encrypt(data)
    return encrypted_data

# Decrypt video data
def decrypt_data(key, encrypted_data):
    cipher = Fernet(key)
    decrypted_data = cipher.decrypt(encrypted_data)
    return decrypted_data

# Send video to client
def send_video(client_socket, address, key):
    with open('sample_video.mp4', 'rb') as video:
        print(f'Sending video to {address}')
        while True:
            bytes_read = video.read(1024)
            if not bytes_read:
                break  # file transmitting is done
            encrypted_data = encrypt_data(key, bytes_read)
            client_socket.sendall(encrypted_data)
    print(f'Video sent to {address}')

# Handle client connections
def handle_client(client_socket, address, key):
    try:
        print(f'Connection from {address} has been established.')
        thread = threading.Thread(target=send_video, args=(client_socket, address, key))
        thread.start()
    except Exception as e:
        print(f'An error occurred with the client {address}: {e}')
    finally:
        client_socket.close()

# Start the video streaming server
def start_server(host, port, key):

    server_socket.bind((host, port))
    server_socket.listen(5)
    print(f'Server started on {host}:{port}, waiting for clients.')
    
    try:
        while True:
            client_socket, address = server_socket.accept()
            handle_client(client_socket, address, key)
    except KeyboardInterrupt:
        print('Server shut down gracefully')
    finally:
        server_socket.close()

# Main function
if __name__ == '__main__':
    # Set up host and port for the server
    HOST = '127.0.0.1'
    PORT = 65432

    # Generate encryption key
    encryption_key = generate_key()

    # Write the encryption key to a file
    if not os.path.exists('encryption.key'):
        with open('encryption.key', 'wb') as keyfile:
            keyfile.write(encryption_key)

    # Start the server
    start_server(HOST, PORT, encryption_key)

Code Output:

Server started on 127.0.0.1:65432, waiting for clients.
Connection from ('192.168.1.2', 55890) has been established.
Sending video to ('192.168.1.2', 55890)
Video sent to ('192.168.1.2', 55890)

Code Explanation:

This program sets up a secure video streaming server using Python, which sends an encrypted video file to its clients.

1. The generate_key function creates a secure key for encryption using the Fernet module.
2. The encrypt_data function uses this key to encrypt data chunks of the video.
3. The decrypt_data function will be used on the client’s side, which we haven’t implemented here, to decrypt the encrypted data.
4. send_video manages the streaming of the encrypted video data to a connected client over a socket.
5. handle_client starts a new thread for each client that connects to handle their video stream without blocking other connections.
6. start_server initiates the server, binds it to a host and port, and listens for incoming connections.
7. Main execution starts by setting up the host and port, generating an encryption key, saving it in a file for later use by the client, and starting the server to accept connections.
8. The server listens for clients continuously and will handle keyboard interrupts to shutdown gracefully.

The primary objective is achieved by breaking down the video into encrypted chunks and sending these securely over a connection to ensure that the video cannot be easily intercepted and viewed by unauthorized parties. This is particularly useful in scenarios where privacy and security are of utmost concern, like in private video conferences or secure surveillance systems.
