Autoclick security for a like button

Hi everyone I want to develop a button like 'facebook like button'. I am going to u开发者_如何学Cse it on my website and thinking it to share as iframe like facebook but I cannot think its securty because someone can develop a script that can click on it automatically.

I thought a solution using sessions but I couldn't make an algorithm completely.

How can I disallow autoclicks and which solution is the best? It can be any language I just want algorithm.

Thanks, have a nice day.

Edited : Think a website like facebook. I login facebook and I can click on like button on any website.

Move to a new page and allow the logged in user to confirm that they were the ones who clicked the like button.

I'm not sure that there's a surefire way to prevent clickjacking or the type of fraud you're referring to, given that you want to place your button in an iframe.

See http://ha.ckers.org/blog/20081007/clickjacking-details/ for more info.

You can't prevent this, once you have generated the like button, the button can be access directly. You just can protect yourself using client side defence technologies like Comitari supplies.

They have a free product that protects you against ClickJacking and LikeJacking attacks.
