In this activity diagram for an e-voting system, the process begins with the user initiating the voting process and proceeding to authentication. If authentication is successful, the user selects a candidate, confirms their choice, and submits their vote, which is securely recorded in the database. A voting receipt is generated to confirm the successful submission. In case of failed authentication, the user is prompted to retry or exit the system. Similarly, if the vote is not confirmed, the user can reselect their candidate or exit. All paths ultimately converge to a single ending node, ensuring a streamlined and unified process flow for both successful and unsuccessful scenarios.
