QuestionAnti fraud voting system w/o login. Pin

Hi,

I am developing a voting system for a company, everything is going OK but the ability to detect and reject fraud votes.

Currently I am using cookies to determine whether the user has already voted or not, but this is not enough at all becoz a normal user can delete the cookie and vote again and again! A hacker can write a small program to send thousands of web requests that hold no cookies at all, which is of course a disaster!

I though about saving the IP address of each vote and block multiple votes from one IP, but there are many shared machines in cafes, universities, etc. Furthermore, many machines may be behind a firewall which means they will have the same public IP address.

I am sure that there are techniques to solve this problem but I couldn't find any by googling it, any ideas from experts?

ps: I don't want a ready-to-use solution, I want to write it myself coz I want to learn it.

Thanks everybody! Rose | [Rose]

And ever has it been that love knows not its own depth until the hour of separation
