Blockchain E-Voting Project
Abstract
The platform behaves as fully indepedent and decentralized during the voting process. The data is transparent but the identity of the voter is secured by homomorphic encryption. I have tested and compared this solution in three different blockchains. The result shows that both public and private blockchains can be used with only a difference in speed.
Goal
In the natural course of tech developments, e-voting will eventually become a norm. Blockchain enables a smart, secure and efficient election system making the process of voting faster, simpler and cheaper while increasing voter turnouts and supporting more effective democracies. With every vote being inspected by independent validators, elections are harder to rig.
Results
Although we see a slight difference in network times, they are negligible. Public blockcahin regardless has more advantages in an electoral system due to its openness of data and that it is updated in real time. A private blockchain is faster but it reduces the credibility of the whole system by being partially centralized because it only runs where the authority wants it. Private blockchain can be proposed as a future enhancement to add more possiblities of adoption.
Libraries Used
Django Framework
Django library is used for the web framework of the application for hassel-free development. Used in this project for shortcuts in rendering with the HttpSessions.
Helped with messages and requests.
hhhhhh
Keras
A high-level, deep learning API developed by google for implementing neural networks.
Imported Maxpooling2D, Dense, Dropout, Activation, Flatten, Convolution2D, Sequential.

Hash Library
Using SHA256, that is secure hash algorithm 256-bit long, used for implementing cryptographic security in this project. This assits us in fingerprinting.

PyAES
This is an inbuilt python algorithm used for implementation of AES which helps in encryption and decryption of data.
PBKDF2 is used here to generate an encryption key from password string then use encrypt key for encryption of data.
PyMySQL
This is a pure-Python mySQL client library. In this project it is used to establish a connection with the database SQL 5.5. Connection established with the host, username, password and port.

Numpy
Numpy is a python library used to perorm mathematical operations specifically on arrays. In this project it is used to generate random strings and arrays.

Smtplib
This is a simple mail transfer protocol library inbuilt in python which is in this project used for sending OTP for the E-voting through email id of the user. This is an added layer for the user validation.
hhhhhhhhhhhhhhhhhhhhhhhhhhh
Base64
This python library is generally used to encode and decode data. Here, in this project it is used to transport the data in binary format over mediums that cannot handle binary data.
We used Binascii to convert between binary and ASCII values.
Proposed System
djanga
A high-level python web framework that enables repid development.
This is a back-end langugage
I have used several frameworks from the same.
Javascript object notation is a text-based way of representing javasript objects, literals, arrays and scalar data.
It is PL independent.
Consists of documented list of users eligible for voting.
Eliminates duplication of votes.
Manages integrity errors.
Restricts the users from registering wwith same name and photograph.
