Recently, I built a voting system for an entertainment portal, but it was also plagued by vote fraud. I used all available methods. But none of them are ideal. In the end, I figured out the following method, and I made a flow chart to share with you.
If you don’t understand the process, don’t get too confused. I won’t give too many boring explanations. Of course, this process is just a general process, and there are a lot of judgments in the middle. The main one used is session. Because of the verification code and so on, then don’t use it in the Internet voting system. No one will verify it, and it will be annoying at first sight. Again, what I wrote in my WEB development notes are simple ideological things. If you want to improve them, you can expand them yourself. I don't have time to explain.
In the following flow chart, you must pay attention to the logout of the session. That is, after a session is used up, you must remember to log out, otherwise it will still be bypassed by the ticket machine.
