The proposed system is to produce a voting system that enables aspirants and voters to have a secure, non-biased and transparent means of registering and voting.
How The Program Should Work:
The program is to allow all Aspirants to register under the authentication of the Electoral officials.
The program then allows the voters to register on the system also with authentication from the Electoral officials but before the voters are allowed to register, the system checks if they are at least 18 years old. If all criteria are met, the voter is given a unique ID to vote.
The program allows all qualified voters to vote by requesting for the unique ID given to them during registration. The unique ID is checked for its validity before allowing the voters to cast their vote.
The votes are recorded and stored. The program is ended by the Electoral official by inputting the correct password. If the password is right, the result is displayed and the winner is declared. If there is a tie, the system declares a tie.
The Actors of the system:
There are two set of actors in this system
The Voters
The Aspirants
The Voting Officials
The System Requirements
