Hi,
I need to develop a once-only voting system using ASP. I have a voting script that stops users voting from the same computer, via IP and/or cookie, but that does not stop the same person voting multiple times from multple computers.
Therefore, what I'd like is a front-end sign-on screen and provide all (known) users their own unique username/password or just a unique password with a one-time validity only. Once they get past the first sign-on challenge, they are passed onto the voting screen where their vote is anonymous. Of course, unknown passwords should be rejected.
Then, if they try to sign on again with the same password, it tells them they have already voted. The administrator should be able to also see who has not voted.
Any assistance appreciated.
