有没有办法获得唯一的计算机ID？

Question

We are looking for a way to know from what computer our silverligth or web application is running. We first wanted it to do by MAC adress but we found out that silverligth can't access the mac adress.

I was wondering is there a way go get a unique computer adress like a mac adress or something else pc unique? by silverligth/javascript/html or something else web based witout installing anything on their pc?

Thx Matthy

This tutorial walks you through it:

Answer 2

Generally it isn't possible to get a 100% unique identifier for each computer, however it is possible to get it somewhat unique. I have previously implemented some javascript/java code to do that. It worked by generating a hash from a few characteristics of client's machine:

• Fonts installed on client's machine
• Java version
• Silverlight version
• IP address

The combination created a somewhat unique identifier for each client, although it is very possible that several clients would have the same identifier. Or something like that... It was a long time ago.

(The whole thing depended heavily on having Java or Silverlight installed. Also user would need to allow the site to run the applet...)

I would suggest not going that way and simply accept the fact that it's not quite possible and find other solution to your problem.
