Q:

Flex 4.5 - unique computer information

I am developing a flex 4.5 web based application and I need to make sure if the client chooses a certain level of security, each user can log only from an authorized computer.
So the question is how can I get some unique computer information? Anything like HDD serial number, CPU specifications, motherboard information, even the user that is logged into the Operating System can do.
So far the information on the web isn't giving me much hope that this can be achieved, but I had to ask.
Thanks in advance.

A:

This is not easy using a browser based Flex application, but there are some workarounds.  
The browser based Flash Player can communicate with an AIR app on the desktop using localconnection.  So, you could create an AIR app that utilizes NativeProcess to retrieve your machine specific information.  
You could also use NativeProcess from a AIR app without using the browser at all.
A third option would be to install an application server on the client machine and have the browser based app communicate with the server to retrieve the client information.
I consider most of these options too difficult to be practical, but it depends on how important this feature is to you.
