Design a secure Online E-voting System

AIM
* Design a secure Online e-voting system that can provides 2 or more out of these below : confidentiality, anonymity, integrity, authenticity, auditability and verifiability. You can implement this in any language of your choice.

- Confidentiality prevents anyone else from knowing who has voted for whom except the voters themselves.
- Anonymity is to prevent the tracking of the voters’ real identities.
- Authenticity is to ensure that voters are eligible with unidentifiable-untraceable signatures of the real votes.
- Integrity is to ensure that no one else is able to change the ballot, and to detect the change if it occurs.
- Auditability makes the election auditable with or without tracing back the true identity of the voters.
- Finally, verifiability enables the system to verify and count the votes, and to detect any missing or fraudulent votes.

You don't have to be able to prove all these above but if you can provide 2 then i will be fine with it .

*** Implementation Design - this specifies how the program works internally ( database )
