Gama (2^nd runner up in Locus codecamp 2023)

Our project revolves around the idea of building a browser extension that empowers users to navigate the web with confidence by detecting and warning them about phishing sites, fake reviews, and other online threats.

Requirements

Python 3.11
Whois cli
pip

Installation

Install gama with git & pip

    > git clone https://github.com/PhuyalGaurav/gama.git
    # now be in the gama folder & make a venv
    > cd gama
    \gama> python -m venv venv
    # install all the dependencies
    \gama> venv\Scripts\activate
    (venv) .. \gama> pip install -r requirements.txt

Deployment

To deploy this project run

  # be in the root gama folder
  # make sure you have your venv activated
  \gama>venv\Scripts\activate
  (venv) .. \gama> cd backend
  (venv) .. \gama\backend> python app.python
  # Now the local server should be running

Use of some thechnologies and why?

Libraries Used	Why?
Fast API	We Used to fast api. Because it is very light weight and also new!, we also went with a api approach so that other developers can use our api to integrate it in thier own applications
Sk Learn	Since our data set was quite small . We went with sklearn rather than tensorflow. Also with our limited hardware we could train with it easier than tensorflow that utilizes heavy & expensive cuda cores
Whois	We choose whois cli instead of an api because we wanted to keep this as free as possible and also keep the delay between front & backend small.
Chrome extention	we went with chrome extension to make this as usable as possbile & reach as many people as possible we are planning to add firefox in the future so that it reaches mobie uses too

How to use the extention

After the server has been set up. Add the frontend extention to your web browser . Make sure that developer mode is enabled.

Now Load unpacked

Now select the frontend folder from gama directory

Now the extention should be installed. go ahead and pin it. so:

Now the extention is installed!

Your extention should be shown like this with details

Now whenever you visit a suspisous site the above screen is shown protecting you from online threats
If you wish to Disable this just click the checkbox

If you ever find a site that seems suspicous you can report it by just reporting it in the textbox like so:

If you want to check for a fake review then highlight the text and right click

Now click on gama and click on Review check

Now you should get a notification like this:

If you would like to check for fake news follow the same process just click on news check :
Then you should get a notification like this

Appendix

The python server is easily uploadable to the web & serve use through online apis
The apis can be used by 3rd party apps too.
The machine learning models are trained on datasets found on kaggle (With the creators permission )

Model accuracies (pre tested)

Fake News Model : 81.23%
Phishing Detector Model : 78.93%
Fake Review Model : 73.22%
