A responsive web application for server-side image scrambling.
safedun-server is a server-side image scrambling web app.
The following instructions will help you get safedun-server up and running in your preferred server/port. Before proceeding to the installation, make sure that your system contains all the prerequisites.
safedun-server is built on Python and uses external libraries like numpy, opencv and flask. Follow the instructions below to setup your system.
1. Install Python 3.6+ (Anaconda distribution recommended)
Run the following command on the terminal/command prompt to install all the dependencies:
pip install numpy opencv-python flask
Clone safedun-server repository into your system using the following command:
git clone https://github.com/adildsw/safedun-server.git
cd safedun-server
python server.py
Upon successful server hosting, the terminal/command prompt should return the following message:
* Serving Flask app "server" (lazy loading)
* Environment: production
WARNING: This is a development server. Do not use it in a production deployment.
Use a production WSGI server instead.
* Debug mode: off
* Running on http://x.x.x.x:port/ (Press CTRL+C to quit)
http://x.x.x.x:port/ is the address of the hosted server.
Once the server is up and running, open the address http://x.x.x.x:port/ (refer to terminal/command prompt running the server) in your browser to open safedun-server.
Open the terminal/command prompt running the server and press CTRL+C to terminate the server.
safedun-server offers the functionality of scrambling and unscrambling images using specific keyphrases and cycles.
- Operation Mode: choose whether you want to scramble or unscramble an image
- Cycle: select the number of cycles you the want the scrambling/unscrambling to go over
- Key: input the key you want to scramble/unscramble the image over
- File: select the image file you want to scramble/unscramble
NOTE: Unscrambling should be done with the same key and cycle which was used while scrambling the image.
safedun-server allows users to change the default host IP, port number and activate debug mode.
python server.py --local True
python server.py --host x.x.x.x --port xxxx
python server.py --debug True
NOTE: By default, safedun-server attempts to host the server in the system's local network with the default port 5000.
