BlockChainVoting

Special thanks to Vincent Mühler for open sourcing efforts on face recognision npm package Face API.

As the viewer of this repository you get an additional privilege to run this project without generating an infura ropsten network api key as it is already hardcoded into the code.

How to run(I personally love Debian Linux so the instructions are written accordingly.)

Step 1: Clone this repository using the command.
git clone https://github.com/pranav3714/BlockChainVoting.git

Step 2: Navigate to the cloned repository using.
cd BlockChainVoting

Step 3: Install the dependancies using.
npm i

Step 4: Use mongodb database.(This is a basic database architecture for test purposes only.)
Database name: panDatabase
Collection name: users
Document schema: { _id: objectID, name : string, pan : string, phone : string, image: base64encodedImage}
Document Sample:
{ _id : ObjectId("5e07a89511fe041fb1668b97"), "name" : "Raman Raaj", "pan" : "AAAPL1234C", "phone" : "9324679902", image: base64encodedImage }

Note:
    Image of user can be encoded to base64 programmatically or using any online tool.(input image format expected is jpeg)
    _id is automatically generated by Mongo
    concepts like indexing and user authentication for efficiency and security respectively
    Image can be inserted to the database using the image.js file in the project directory.

Step 5: Run the app.js file using node
node app.js

Step 6: Open a web browser and type in URL:
http://localhost:3000
