Help Unique Identifier of a computer

Post by dacoda »

Is it possible to get an unique identifier of a computer using PHP? Because I am creating a web application, and what i want to happen is I want to register any unique identifier of the user's computer so that he/she cannot use his/her account in any other computer. Is that possible?

From a web app, no you can't.

Best you can do is check their IP address, which can (a) vary, and (b) be forged (or so I'm told).

Your best bet is a licensing server, some companies spend millions of dollars investing in special hardware "keys" that have to be installed for licensing reasons that just end up getting bypassed by the crackers anyways
@tasairis, I think he meant restricting the installation of his code base, not direct end users
